Noobish question, but will i need to change the spark plug, or should it be fine connecting my db-06 to the sparkplug in the lifan engine?

MICRider 08-19-2012 03:43 PM

Sparkplug is fine, no worries there :). So the donor bike was a good running bike? That thing must have been a bear to get into the van! Probably had to lift/drag it in? What was wrong with the donor bike that the previous owner got rid of it?

katoranger 08-19-2012 04:34 PM

I believe he said that it was wrecked. Bent front wheel.

Looks nice and clean. Lots of good parts too.

SpudRider 08-19-2012 05:37 PM

Thanks for starting the new thread, Gamma! :D You scored big on acquiring that used bike; the parts alone are worth well more than $375! :D

Are you and Zombie twins? :?:

Spud :)

Spud :)

Yeah we scored big on this bike, and no haha, we're not twins.

The engine is in, Fit perfect! we got it done in an hour and 20 minutes. went very well!

Have company at the moment, So i'll finish assembling it in a couple hours. I'll take some pics of it before i start the re-assemble process.

Question! Will my Roketas sprocket engine sprocket fit on the new lifan engine, is the counter shaft the same size? I can check it, but if you know off hand, lemme know.

Wooooo!

SpudRider 08-19-2012 06:09 PM

You work fast! :D Make sure you applied red loctite to all the engine mount bolts, Gamma. ;)

I think the countershaft sprocket will fit perfectly; however, the only way to know for sure is to experiment. ;) We eagerly await your additional photos. :)

Spud :)

Yeah the front end is the only thing that had damage, the blue headlight plastic was cracked up, and the side faring had a crack.

Kid we bought it from was hit by a Lady who wasn't paying attention and pulled out infront of him. He flew over the bars, said he flew like 10 feet, but was okay, other than his lag being jacked up for a while. got rushed to ER. Good thing he's smart and wears a helmet. Was probably 16 or 17 years old. Got a decent pay out though, more than he paid for the bike. witch is good.

He and his dad helped us get it into my bros jeep grand cherokee, his dad made it A LOT easier.

MICRider 08-19-2012 06:24 PM

Sounds like a great score to me! As Spud said, it's worth way more than that in parts! Heck, I think I paid about $350 or $400 just for a 125cc Lifan, no bike included :lol:

Great idea, Dude had two of the bolts missing from his. Will get some red loctite and do that.

Okay, cool. Yeah i'll check it out (countershaft sprocket)

I took some pics of both bikes stripped down and i'll take some more in a bit. Expect pics later on today !

Also, Only 4100 miles on it :D

driller 08-19-2012 08:36 PM

Depending on your riding intentions you may want the sprockets off the lifan, they are set up for highway and yes they will interchange. The lifan uses 17/43 if I remember correctly this equates to about 70 mph at 6500-6800 rpm the rocketa bikes are usually much lower and believe me 1st gear will still climb most anything you need. :D

TheGammaGhost 08-19-2012 09:09 PM

Okay, Everything is about together, But the Counter shaft sprocket from my roketa engine didnt fit, so i am trying to get the Rear sprocket from the spare bike, on my DB-06, Ran into a problem though...

On my DB-06 wheels rear sprocket, One bolt is stripped to hell, and i cant get it off, there is a little rim around the 4 nuts, so i cant really use needle nose vice grips to get it off, i've soaked it in wd-40, the bolt is almost round, its so stripped, I may try to dremel it off, if i damage the bolt its self, can i replace it.

other than that it seems good so far, haven't started or rode it yet, but once i get the lifan sprocket on my wheel, I'll be good, Any tips to do this would be greatly appreciated!!!!

TheGammaGhost 08-19-2012 09:38 PM

i may dremel the little rim thing to get at the bolt with a pair of vice grips. im pretty positive its just part of the sprocket.

should be good to go tomorrow, if i can get that Stripped Nut/Bolt off

FastDoc 08-19-2012 10:25 PM

Awesome news. This will be a fun successful confidence and friendship building experience.

For sure, I will be using the Lifan sprockets, My Roketa engine sprocket didn't fit, so I'll be using The Lifans counter shaft and rear sprocket. Can't wait to feel the difference!

As for the striped rear sprocket nut, they have an easy out kind of thing, for nuts/bolts, ill pick the tool up tomorrow, and i should be set. Can't wait! added some pics from earlier today. will take pics of swapped engine tomorrow!

Weldangrind 08-20-2012 12:02 PM

Mmmm... cheddar popcorn.

I've loaded many dead bikes into Dodge Caravans over the years; I know what a struggle that can be. Now, I use a bike hauler on the Class III receiver, which just requires a couple of tie-downs. much easier.

Great job, guys! :D

TheGammaGhost 08-20-2012 03:47 PM

Okay, it's 100% put together...

Its not being as easy to start as i had hoped, Right away i tried the electric start, did it to much, and now it the electric start isnt working. it did sound like it could have started with it, if i had done it properly rather than just holding it.

Now im trying to kick start it. Very tiring, Going to keep trying, I hope i can get it!

TheGammaGhost 08-20-2012 04:07 PM

Can't seem to get it kick started, im trickle charging my battery right now to see if i can get it to that way.

Any tips?

FastDoc 08-20-2012 04:08 PM

Did you start it before the transplant? In it's orginal frame?

I did not, wish i would have. they did state the engine was fine though.

TheGammaGhost 08-20-2012 04:12 PM

On the 3 cords that go from the engine to the bike, They all fit, but i did notice, the smaller plug, on the female end on my roketa, only had one pin, where as the lifan frame/body had more.

not sure if that could be it, i doubt it, it seems good, Maybe the spark plug? it says NGK on it.

FastDoc 08-20-2012 04:14 PM

1st things first.

Are you getting spark and fuel?

TheGammaGhost 08-20-2012 04:15 PM

How do i know if im getting spark? and i did hook the fuel up, and turned it on.

TheGammaGhost 08-20-2012 04:32 PM

Ahhhg, i dont know what to do!!!

FastDoc 08-20-2012 04:33 PM

Remove the plug from motor. Leave the cap/wire on. Rest base of plug on clean bare ground on chassis or engine. The head will do. Dim lights if possible and crank engine. A bright blue snappy spark should appear in the plug gap. Please test and report back.

TheGammaGhost 08-20-2012 04:36 PM

ok

TheGammaGhost 08-20-2012 04:41 PM

okay, tried both plugs, No spark.

FastDoc 08-20-2012 04:55 PM

There's your problem. Check CDI connections. Make sure kill switch is not stuck on or grounded. Check spark plug lead and connection to the cap.

TheGammaGhost 08-20-2012 04:57 PM

okay, ill go check it out right now. will report back shortly.

TheGammaGhost 08-20-2012 05:09 PM

CDI is all plugged in. How do i know if my killswitch is grounded or not?

MICRider 08-20-2012 05:18 PM

Does the donor bikes CDI look identical to yours? Is that the plug with the different pin out?

TheGammaGhost 08-20-2012 05:24 PM

Yes the CDI looks basically identical, the same amount of cords.

No the difference is the female part that the engine connects to, only had one metal prong, where as the donor bikes has i think 6.

the cord is Not the ground, and not the bigger connector, its that smaller green one.

TheGammaGhost 08-20-2012 05:25 PM

Man............ this sucks, i dont know what to do :x :x :x :x :x

TheGammaGhost 08-20-2012 05:36 PM

the cord that has the different pin count leads too the magneto, dont know if that helps...

I hope this isnt how this ends for me... man....

FastDoc 08-20-2012 05:41 PM

I forget which color wire it is but someone here may have posted the wiring diagram. You may be able to see the color coming out of the switch and/or the harness. You may also want to try switching CDI's and make sure the coil wires are attached/grounded as need be.

Look at your pics of the donor-cycles wiring to confirm.

TheGammaGhost 08-20-2012 05:53 PM

MAN!!!!!!!!

im so confused, as to what to do. or what it could be. The cdi is shaped a little bit different, but its the same cord count.


this makes me so mad.

FastDoc 08-20-2012 05:57 PM

IIRC there are 2 CDI styles. One with rounded plug and 6 wires the other a square plug and 6 wires. It may matter.

TheGammaGhost 08-20-2012 06:01 PM

yeah he has the rounded like plugs, I have the other kind.

i'd have to remove the plug head and swich em, to make it fit, the bottom one with 2 wires. i have no idea if thats right/okay though... :(

FastDoc 08-20-2012 06:09 PM

Don't do that yet, but this might be the problem. I kinda wish you checked the transplant engine before removing it... Oh well live and learn.

Wait for Weld or Kato or someone with more Hondoid experiance than myself to check in. This should not be a big deal. :wink:

TheGammaGhost 08-20-2012 06:10 PM

Alright, Ill be patient, Im hopefull we can fix this.

really thought i'd be riding today though, oh well. :roll:
