big trouble!
 

okay, i was riding down one of the main streets and i rounded a corner in first. i let out the clutch and the bike felt like it stalled out. i started the bike right up and it runs with a horrible "clacking" noise coming from the case. the bike started up good and it drove to the next driveway good but i am now elbow deep in it and i have to have it running again by wednsday. i already got the magneto side off and everything looks okay. and ideas?

first off, I wish you the best of luck.

now I have to ask when the clatter starts? does it do it at an idle, at high speeds, when the clutch is in or out?

Give us a better description and we can be more accurate with the suggestions.

Peace Health and Prosperity,

Alonzo

edit: since you are pulling the cases, you might as well check this how to out and do some preventive maint, http://www.chinariders.net/modules.p...ewtopic&t=5141

You aren't riding with the kickstarter flipped out?

okay, it makes the noise at ALL RPM ranges (although i tried to keep them low giving the circumstances) it makes the noise in neutral, 1st. i didnt get it over 1st for fear of more damage NO, MY KICKSTARTER IS NOT OUT/ DOWN. its not anything loose in the clutch side of things and its not in the magneto side. are there any pics of this motor split down the middle so i can see what im getting into?i will be checking this regularly to get more help and advice from you guys so....

okAY, THE BIKE IS ON A STAND AND IT SEEMS TO MAKE THE NOISE LOUDER WHEN ITS IN GEAR. this is done by putting it in gear and using the kick starter to turn the motor over (duh) i REALLY DONT WANT TO TAKE THIS MOTOR OUT!!!!

What did the oil look like was it silvery or did any chunks drop out when you drained it into a very clean container ?

Is it an OHC engine or pushrod ?

Can you shift it into all the gears just by hand and maybe rotating the rear tire and with the spark plug out to make it easy?

it goes into all gears relatively smoothly, the plug is out, both engine covers are off, it turns over smoothly and it hangs up just a little at TDC its a pushrod motor and..... i think that answers all questions. i HAVE to have this bike running. i am trucking it to california and i am going to be riding it around down there. otherwise, i will have to call for rides from my MOMMY's house. and no one wants to make a comeback asking for rides everywhere.... hell, no one wants to make a comeback on a chinabike! (i do)

have you checked the valves yet ?
making sure they both go up and down as you turn the engine and that they are set right.

the oil had a VERY small ammount of silver in the drainage. ONE THING! when i dumped the old oil from last oil change into the container, thiss spring and thimble-shaped screen came out with the oil. tell me these things dont belong in the motor. that would mean i went 400km with no oil screen!

when i listened to the enging for the 30 seconds i had it back home before i tore it apart, it sounded like it came from the lower half of the motor. i would rather it be the valves so i dont have to tear this whole things apart.

The spring and thimble shape screen belong in there. That is your filter.

Allen

yep that screen was the particle catch for your engine. check the valves. make sure they are at the proper clearance. seems like you have ruled out most of the typicle problems. If it is not the valves, you will probably be pulling the cases apart.

was there supposed to be anything other than the thimble and the spring? MAGNET, filter keeper etc.? i am tearing the valve cover off right now and every minute i get im back in here looking for what you guys have to say. and I REALLY HOPE I DONT HAVE TU PULL THE CASE!!!! anyone else have anything come loose in their crank case?

Take lots of pictures!

Take your time make yourself plenty of space to take the parts out and keep them in order.

Dont get all intimadated over cracking open the case. these bikes where built very simple. you wont be running into a lot of technical stuff.


oh ya when you start removing bolts use a torque wrench and write down the ft lbs for the bolts you pull.

okay the valves have ZERO clearance between the rocker arm and the valve rod. whats the specs? i went to auto zone and stocked up on loc tite,black rtv and energy drinks. im not intimidated, im lazy. this sucks! oka, i will be back to give you all an update.

adjusted the vlavess to .002 (i think) and there is slightly less resistance on the engine but there is still the noise.... gonna crack her open....

good luck bud, hope the repair mission goes well...report back your progress...!!

okay, the case is apart and there were NO loose nuts or bolts floating around. i called my buddy and he told me to look at the main bearings and to see what color they were. they are a dark purple. so, sometime in the 798km this bike has been ridden, the main bearing lacked lubricant. im sorry about not having pics but my camera is dumb and i cant figure out how to get the pics on here. so, do i button it back up and ride the piss outta it then replace it with a XR 200 motor, or find a new bearing and rhen ride the piss outta it? im thinking ride the piss outta it and then change the motor. i love having a garage. at my old house, i would have done this on the kitchen table. (maybe THATS why she left me!?)

and here i was bragging about lucas! man, note to self-NEVER USE LUCAS ON A NEW MOTORCYCLE ENGINE!

purple!?!?!?!?!?!

that is not natural. if you look around you can find a ohc lifan for probably half the price of the xr and it will bolt up directly. check out hooper imports for a lifan engine. and then try ebay. make sure to check the seller out really good. you dont need some hack taking your monies and not shipping.

Not much I can do, sorry to hear of the problems. I was gonna suggest video taping the opening of the case so you can retrace all your steps.

ya i wasn't worried about how things went back together. im always more worried about stripping nuts/bolts out. so, yeah the magneto-side crank bearing was purple. not barney purple. more, a BURNED chrome purple. i have the bike prepped to be put back together in the morning. im just going to ride it till it pops. i just hope it dont lock up on me going 55 down the road. who knows, now that its toast, i should 50/50 lucas and dino and see how far she goes!
you know, im not wealthy by any means. in fact im pretty poor. i got this bike cause i drive thirty miles t and from work everyday. i am a single baby's daddy with no help from the b***h mother. if i cant squeze another month or 2 outta this motor, i might just have to part it out... thats asking alot from a purple bearing but i dont have much of a choice. what i would give for a klr right now. this is real depressing. S**t,G*D damn, F**K!!!!!! okay, now that i have got that out, its time to start searching for a solution to this problem. thanks for your help guys. i will let you all know how the booger bike works out. and how long the purple bearing lasts. isnt it beer-thirty? yes, it is!

purple bearing, green bike..... this is starting to look more and more barney like every minute!!!!!!

this should keep you rolling on two wheels

i was JUST getting back on to tell you all i might have fount a solution and here, you already have THE EXACT SAME SOLUTION!!!!! but, my question is, do i split the case to try to find any of the broken pieces? and if UPS did it once, who's to say they wont put 2 chips off the ol' block? haha. im going to look at my finances tomorrow to see if i can swing it. i have a 1993 polaris indy that i might have to sell to get this motor (wink wink) anyhow goodnight guys and THANK YOU FOR ALL YOUR HELP!!

There is a wholesaler near Lawrenceburg Indiana (Elrod In actually) This is where I bought my bike. Its a Roketa but it has the OHC non counter balanced engine. I have 4400 miles on mine so far, and its been great. I will be needing anew clutch soon, and I asked hime about parts.. the complete basket was $85, but he also told me he would sell me a complete new engine that came from a busted bike (shipping damage) for $150 engine will be minus the carb and starter.
He does not always have parts bikes around, but you could ask him. Price may vary since he knows me and I was a customer.

Here is his number and web site.

And not to be a a jerk, but your engine failure had nothing to do with the Lucas and everything to do with you running without a filter... seems kinda strange that if something fell out while you were doing an oil change that you would not find out how to put it back in.

I would do as you said, and just run the snot out of it... those end bearings are ball bearing type bearings.. so they will probably make LOTS and LOTS of noise before they actually fail. But I would be careful about getting into situations where the wheel locking might kill you... Like on the interstate.

Good luck with your bike.

Ken

If ball type bearings are making noise and have purpled the race, then forget it. The amount of miles left on that motor are negligible and it just ain't safe. It's not a car....

Pulling engine parts outta your flesh is no fun, nor is a rear wheel lockup followed by chain wrapping around your leg..

Anyone got a good bottom end for him?

Allen

He might be able to take the bearing out and match it up at an industrial supply house. I've done that many times, usually you can get some really high quality bearings at less than half the price you'd pay anywhere else.
Most of the time the bearing will have an ID number on both races and can be cross referenced. If there's no number it's not hard to match ID, OD and width. Just don't get a sealed bearing as it will need oil flowing through it to carry the heat away.

I agree! I have done that many times with bearings that don't even have any markings on them. They should be able to measure what you have and get you another one. When you install it, just make sure that you don't pound it in the wrong way. If the store is worth anything, they should be able to tell you the right way to do it. If not, let us know and I'm sure someone here can tell you.

I wouldn't just ride it until it explodes, that makes it a much more expensive fix. If you just fix the bearing you would only be into it a max of $30.

Just a thought... :D

THaNKS GUYS! i am going to call the gentelman about that motor. and its not that i didn't know how to put the filter in, the filter fell out without me seeing it last time i did an oil change and i never knew there was supposed to be anything there untill i drained my oil from the container and found the parts at the bottom of the catch. man, i know you guys are right. but its expensive driving my truck to work and back every day. i dont know anyone to carpool with so, my options are limited. i will just get a new motor. this one has been giving me a hard time since i got the bike. if it isnt one thing, its another. and as far as replacing the bearing, i could do that but alot of people around here see chinabikes as taboo and wont help out when they find out what its for. i can explore that option and rebuild this one for a spare... okay well i am going to get busy with the bike. i will let you all know how it works out.

if that guy does not have any deals going this guy is a good dealer yes there is a good price too. but I am pretty sure that is the counter balanced engine and it is worth every penny.

Buy yerself the magnetic drain plug from the parts list. That strainer isn't so great in the first place.

As for the bearing, don't tell 'em what it's for, they can't use that info anyway, just bring the bearing to 'em and say 'i need one like this'.

Personally, I find less talk is always better when dealings with possibly hostile parts guys. Grunting usually works better.
Example:
Me: (Cave-mechanic) (Holds bearing out at arms length, towards parts guy) "Uhhhnnn!"

Parts Guy: "What is it for, sir?"

Me: "Uhhhhhngha!" (Poking bearing now lying on the counter)

Parts Guy: "Do you know what year it is?"

Me: "Uh-uh. (pause, point) Unnnt!"

--Usually they just go to the book and get creative, saving me a bunch of time explaining that it's a 1991 VW Jetta, with a 2001 VW Beetle TDi engine in it, with a SAAB intercooler, etc. I figure, I should use my stupid to my advantage, 'Cause hey-- Sometimes Stupid works!

--Vince

The biggest, multi-make carrying dealer closest to me wont even look up a part unless you tell them what year-make-model, they just sit on their little stool and stare at you.(Its kind of funny in a way but totally useless)

The smaller aftermarket shops are a bit better to deal with.

I think dropping another engine in it will be the quickest solution but very pricey.

[quote="VinceDrake"]No!!! you are no longer allowed to play stupid! when you fuse three totally different cars togather into some sick german jalopy nightymare you can't play stupid. It is inmoral and inappropiate! :lol:

As for the thread, sorry to get it all off track but yes, definatly go to the industrial parts guru first. then try to get yourself an engine.

let the beating begin!!!! i was looking VERY closely at the motor as i was putting things back together and DOH! look at the CAM GEAR STUPID! its missing TEETH. i took a pic with my cell phone since i should be wearing a helmet everywhere i go. HOW THE HELL COULD I MISS THAT?!?!?! the bearing is still pretty messed up but i KNEW that couldnt have been the source! but , i never tore into the motor before yesterday.if you look VERY closely, there are "thread" marks where the teeth are missing. i do believe a small bolt came loose somewhere and locked it up.man, i feel really stupid. but the caveman in the industrial parts store line made my day better. now, how do i get a new cam gear,install it, and put the motor back in my bike in less than 24 hours.... (trip to california and i leave midnight tomorrow.) and i still cant figure out how to post pics..

good luck with getting a cam gear at any speed. I can't even get a jap mastercylinder rebuild kit any sooner than a week.

then again a gear is a gear right?!?!?!?
might once again try a industrial parts store to get a gear. if that dosent work, try to cross the parts at the honda shop. "look for the oldest crusty guy behind the counter" he usually can eyeball parts for a good match.
