bogies next crazy idea....WARNING Supermoto content...

[bogieboy]

so... ever since i started watching youtube vids of supermotos, i have wanted a su-mo...now thats gonna happen, and on the dirty cheap too... to start this off, i picked up a set of 1987 kawasaki ex250 ninja rims...for $113 shipped... need to get a cush drive hub for it, and a proper sprocket but other than that, parts are fairly well done (aside from fabbing the appropriate spacers for the rims and making the proper brake mounts...all stuff i can do LOL) so yeah... picture these rims (painted magnesium/goldish color) on my bike...

[SpudRider]

I'm subscribed, BB. :) This looks like a fun project. :tup:

[Wild_Alaskan]

I wouldn't worry about a cush hub too much unless you like to shift without the clutch alot

[bogieboy]

I need the cush hub anyways for the wheel... Its cheap anyways... LOL unless of course i just weld the hub to the wheel... However i do tend to shift clutchless alot...

[Weldangrind]

Do it! I'll make popcorn.

[bogieboy]

Lets see... Sprocket/cush drive hub came to the door saturday, and according to my tracking, my wheels showed up today, via the "brown truck" santa...LOL pics to come of the wheels by the bike in a day or so...

[katoranger]

Brown truck Santa comes to your house too?

[SpudRider]

Santa comes to my home by FedEx and UPS. :tup:

[bogieboy]

Santa comes to my home by FedEx and UPS. :tup:

Ups is "brown truck" santa...LOL And fed ex is purple and orange santa... And the mailman is blue santa...LOL

[recracer]

I'm jumping in for the ride . looking forward to the updates :clap:

[Killerbracing]

Any updates on this? :thanks:

[bogieboy]

Sorry i didnt see the ask for updates.... Well no actual work has been done yet, other than Danita thinking it would be a nice gesture to buy me a shinko 567 front tire and 568 rear as well as a sprocket to convert it to 520 chain so i can use the stock ninja rear sprocket... I did also pick up a rear axle and spacers for the ninja, figure it would be a good starting point for modding stuff...

[bogieboy]

Picture time... On the left we have a 110/80-16 shinko 567, and the right a 130/80-16 shinko 568...

http://i662.photobucket.com/albums/uu346/bogieboy01/20140226_233045_zps1dfa5d98.jpg

The left is the front tire, the right is the rear if you didnt already figure out that fat one for the rear...LOL

[Weldangrind]

What helped you to decide on 16", vs. 17" or 18"?

[katoranger]

Cheap wheels.:tup:

[bogieboy]

Kato hit the nail on the head... Cheap wheels... 17s would likely have run 2-3x as much for decent straightrims...however theres a trade off... Tire selection for road tires is limited to scooter tires for the most part for a 16" rim...

[Daeouse]

This is going to be awesome. . .

[bogieboy]

Well got time to play around today...

Started with this...

http://i662.photobucket.com/albums/uu346/bogieboy01/20140227_162852_zps49a088bf.jpg

And finished the day with this...

http://i662.photobucket.com/albums/uu346/bogieboy01/20140227_171323_zps3ba81752.jpg

Still need to make precision spacers and find appropriate bearings for the front end but with just a few washers as spacers and one spacer from the stock ninja stuff i had, its pretty well set...

Still need to figure out the rear brake mount, and a few other little things...

[Daeouse]

@_@ so cool. . .

[bogieboy]

THANKS!!!!!! all in right now i have $250 into the swap... So much cheaper than buying supermoto specific rims to the tune of $700+...

[katoranger]

I think the scooter tires will be up to the task on a 200cc china bike.

The white wheels look good with the blue. Like a yamaha.

[bogieboy]

I was originally going to powdercoat them gold/magnesium but the white looks so good im not gonna worry about it...LOL This size scooter tires are usually found on the 4-500cc bigger scooters, and some people use these tires on thier cruisers too....they are a 4ply tire, rated for 112 mph sustained...

So pretty. . . I'm such a magpie. . .:crazy:

[SpudRider]

Nice job, BB! :tup:

[Killerbracing]

Oh yeah! I needed that today! Great motivation! Keep with it!

[Weldangrind]

It's a good look. Any Photoshop stars around here interested in colouring the rims gold? How about black?

[Weldangrind]

So pretty. . . I'm such a magpie. . .:crazy:

I had a good laugh over that! :D

[bogieboy]

It's a good look. Any Photoshop stars around here interested in colouring the rims gold? How about black?

Thank you all!!!! As far as PSing the wheels a different color, i will do that in my spare time...LOL so maybe never...

[bogieboy]

Oh as a side note, you dont really think about some things until its happened... The stand over on this bike is now similar to my ke100.... I think over all the switch from 21/18 to 16/16 combo lowered the bike a good 5-6"... May be a viable option for any shorter riders... Oddly enough, the kickstand needed no modifications....its just that short...LOL

[recracer]

Looks good . Great progress in a day . I got away with the stock kick stand . Later I came across another and cut out about an inch ,could have taken more off it. It has enough lean now that I don't worry it will fall over

[Killerbracing]

It's a good look. Any Photoshop stars around here interested in colouring the rims gold? How about black?

I'm not a photoshopper, but, I'm painting my rims black.

[bogieboy]

ordered up wheel bearings for it yesterday... took a while to find a few of them, since they are nonstandard bearings... hardest one to find was for the cush drive... a 15mm bore with a 52mm OD....LOL turns out theres an alternator bearing thats just the right size out there... so i will hopefully get the bike totally together and safely rideable within the next week or so... still need to fab a bracket for the rear brakes though... anyone have ideas?

[Weldangrind]

Can you get the bracket that was meant for the caliper, and then weld tabs on the swingarm to match it?

[recracer]

On mine i modded the factory bracket http://www.chinariders.net/showthread.php?t=10190&highlight=recracer&page=2 have a look here . hope it helps

[bogieboy]

hmm... i dont want to chop up the factory bracket, since i still want the ability to use the stock wheels... but something along those lines may work.... gotta sit down and see what i can come up with....

[bogieboy]

Can you get the bracket that was meant for the caliper, and then weld tabs on the swingarm to match it?

the rear caliper and everything is still the stock caliper... if at all possible i want to make this comversion completely reversuble in case i want to ride in a dual sport event....

[Weldangrind]

If that's the case, I'd track down a second swingarm. Undo the shock bolt, drive the pivot bolt out and slide the swingarm away.

[bogieboy]

if i had the money in the bike budget i would... but thats pretty well depleted right now.... i will have to see what i can come up with in terms of an adapter....

PM sent . please check

[Daeouse]

Behold my quick manipulation!

[bogieboy]

well saturday i got 4 out of 5 bearings in... turned out that i ordered one for the back wheel incorrect...i ordered another of them and hope to have it soon...other than that its almost done... still working on the brake extender though...

[alex_in_az]

this looks pretty sweet, I'm due for a new set of tires soon, I may go for some street ones instead of knobbies

[bogieboy]

got the other wheel bearing in, and had a bit of fun.... even though i still have no back brake....

http://i662.photobucket.com/albums/uu346/bogieboy01/tapatalk_1396098202347_zpsa1536b29.jpg

[recracer]

Looks Good . I have never been good at getting the front wheel up like this. The Goldwing powered up once . Yikes thought I was going to die.

[bogieboy]

i am not gonna lie... its scary at first... the wierd part is i can ride a wheelie on my mountain bike at balance point, which is a far steeper angle, for far longer than i am comfortable with on the motorcycle... its pretty easy to power it up, due to the large rear sprocket, its currently geared sligghtly shorter than the stock 17/56 gearing...its a 13/45 520 chain gearing... i am probably going to get a 38 rear for it eventually, but its kinda nice to be able to hooligan it a bit...LOL i may keep it this way for a while...

[SpudRider]

I'm glad you are making good progress, BB. :tup:

However, I wouldn't pop wheelies without a rear brake. The rear brake is your only safeguard from looping the bike. ;)

[Weldangrind]

The angle of that wheelie looks really cool.

If you saw how the bearings had impinged on the steering neck of my TW (from a previous owner), you'd never wheelie again.

[bogieboy]

so... yesterday i got the brakes sorted... it all started with a trip to harbor freight...why not use chinese stuff on a chinese bike...LOL i picked up a few things, not knowing what all i would need... but heck its cheap, and i can use it for other stuff...LOL ended up getting two packs of 4.5"metal cutoff wheels, and a corded 3/8 chuck drill (my milwaukee 1/2" chuck is a pain in the tuchus... the chuck is so stiff you strip out chuck keys...only way to tightne/loosen it is a pipe wrench and a vise...) didnt end up needing to use the drill, as i decided after seeing another guy do the same (hes a machinist though and i doubt that he used an angle grinder...LOL) i found it the best to cut down the diameter of the rotor... how does one keep things round? pretty simple... put bike on stand, start motor, put in 2nd gear...rear wheel is off the ground, now spinning...steady hands on the grinder, and you start your cut line...because its spinning its like a lathe... took 3 cuttoff wheels, but it worked... i didnt think to take pics of it, but it doesnt really look any different than stock, other than if you look close, you can see the outer most row of drilled holes got mostly cut off...so theres dimples on the edge of the rotor... heres a pic of the guys wheels that inspired me to do it...

look closely at the rear rotor.. he actually took more off than i did, he cut into the second set of holes, apparently his KTM uses a smaller rear rotor... he also cut down the front as well... the stock rotors each drilled line is 4 holes long, both front and back...

http://andrewgore.smugmug.com/Motorcycles/2013-KTM-350EXCF/Supermoto-Wheels/i-wf2bvnN/0/L/IMG_20140323_133350680-L.jpg

[Weldangrind]

That's a neat idea. You were using cut-off discs on the rotor? I would not have thought of that. By reflex, I probably would have gravitated towards a flap disc.

It sounds like your 1/2" chuck has seen better days. If you can get it to tighten around an old allen wrench, it's not to difficult to change the chuck. A genuine Jacobs is only $10 at HF: http://www.harborfreight.com/1-2-half-inch-jacobs-keyed-chuck-45731.html

[bogieboy]

i used the thin cutoff wheels spinning the opposite direction of the wheel, and perpendicular to the braking surface, cutting thru the face instead of sanding down the diameter. i tried 40-120 grit flap wheels and didnt hardly scratch the surface...

as for the ole milwaukee, the reverse doesnt function anymore either...LOL

[Weldangrind]

The switch on the Milwaukee is replaceable. Drills of that quality are rare these days, so it's worth fixing.

I can now visualize how you were cutting the rotor. Makes perfect sense.

[recracer]

Good Work . hmmm makes me wonder ,with no sprocket or brake rotor alignment problems . What would a high strung ninja 250 engine would be like in these bikes. :hmm:

[Weldangrind]

It would be high strung.

[bogieboy]

[recracer]

:lmao: There are tons of them on ebay

[bogieboy]

:lmao: There are tons of them on ebay

i know...LOL wise minds think alike... you can get em for about the same as a china engine with low miles...LOL

[SpudRider]

That's very ingenious, BB. :) Good work. :tup:

[stretch8668]

A ninja 250 would be nice in on of these and would have good power to weight ratio but I'm sure there would be a lot of modding and fabricating be nice if it were a drop in swap.

[Killerbracing]

The ninja engine would be awesome! Can you say dual exhaust?

[bogieboy]

i would rather try and shoehorn a 2stroke twin for that.... i have a soft spot in my heart for smokers... not to mention you could shoehorn a stinkin 500twin in these frames....now THAT would be high strung... my old 250 single (traded it for this bike) would power up a wheelie in 3rd just getting on the pipe...LOLso...roughly 2xthat power....

Oh so sweet!

[stretch8668]

That 250 was that two stroke and four.

[bogieboy]

the old 250 was a 2stroke... 75 kawasaki f11

[stretch8668]

That explains the power then. Only thing I don't like about two strokes is they gotta be rebuilt before a four stroke would but a 250 two stroke has almost double power of a four stroke 250.

[bogieboy]

a two stroke of equal displacement to a four will always make around 190% power of the 4.... my kawa ke100 can keep up with my shineray.... i would say they are about evenly matched in the power.... just the shineray has the edge on suspension believe it or not....LOL

[bogieboy]

so got a few pics of the rotor...turns out the other guy cut his more... and the stock rear has 5 holes per line....LOL

http://i662.photobucket.com/albums/uu346/bogieboy01/20140331_084133_zps9a081238.jpg

you can see a few spots where i knicked the face getting the slot started, but over all not bad for freehanding the grinder... if i did it again i would make up a jig to hold the grinder from moving...

[bogieboy]

oh also, i forgot to post this before.... a JT front sprocket JTF328-13 is what i am using up front for the 520 chain conversion.... and the stock 45 rear from the ninja.... in case anyone else was interested...

and that is all on a 163fml hondoid clone

[Weldangrind]

That's really cool! Did you have to get creative with wheel spacers, so the sprockets would line up?

[bogieboy]

actually no...

front wheel is stock speedo drive in the stock spot, stock spacer on the brake side, and then 3-5 washers to make it all line up proper (i forgot how many i used...LOL)

out back its stock right side spacer of the brake mount, wheel, cush drive, and then just the stock spacer on the left...i ened up using the ninja spacer, even though its pretty similar in size...LOL I paid for em i may as well use em...LOL and no washers out back.

its a fairly straight forward bolt up affair once you swap out the 17 and 15mm bore bearings for 15 and 12 mm bores to fit the axles...

the rear end, aka the wheel and cush drive i used:
one B15-86D-2RS
one LR202NPP
one 949100-3820/B382 AB

for the front i used a pair of:

LR201NPP

and all of those can be sourced from ebay for around $10 each if anyone else is interested! i can shoot links if anyones interested...

[hnu13]

I'm about to attempt this conversion on my hawk!
Can you send me some links pleAse? :-)

[kohburn]

interesting - I've got a set of wheels from a 95 zx6r - may have to take some measurements to see if they can be made to work

[hnu13]

what kind of bike you wanting to put them on?

[kohburn]

the new csc TT250 when it arrives. I commute to work on my bike and wouldn't mind being able to quick swap between sumo and knobs

if not then i'll probably need to ebay them off

links for what? if you search the part #s listed for the bearings and get 86or 87 ninja 250 wheels it *should* work... however, since I do not own a hawk, I cannot verify that the beari gs will be the same... it is best do do what I did... buy a nice digital micrometer from harbor freight, get a set of wheels and start measuring... its pretty much a trial and error thing..:tup:

Not really much to update? I have put 6k miles on the setup with no issues.
