Split cases on 200x

[speed20]

short4stuff, If you find out that you need a left side cover, i may be able to get you one if you would like me to. but side to side play in bearings is not good, especially if its in a motor. the only thing i can think of as to why the crank assembly slides back and forth would be this, and its not likely:
when the motor was running, the OUTER race of the bearings were turning along with the inner race, and it wore the cases stop tabs. that is very unlikely....about how much play does it have side to side with the cases bolted together and everything? i think mine moved side to side about 2mm before i put new bearings and rod in it, but it ran like a champ!

[short4stuff]

yeha mine is probably close to that... my dad said that maybe the bearing locked up at one time and the outer race could of been spinning.. I will look over the case abit better..
Umm i sort of want a new case anyways cause where the case saver bolts on well both of those pieces broke off, so a case saver cant be bolted on anymore.

The thing about this is that the rod was done along with bearings like 1 1/2 years ago.. the last guy that had it apart engraved his name along with 2004 in the crank. he told me he replaced the bearings and rod. the wristpin hole on the rod is also stretched.

your dad is right! probably what happened was when it was running one time (at low rpms) the bearing(s)locked up, which would explain why the rod hole is stretched. but that still doesnt explain the side to side play.....that fact just stomps me....about the only thing you could do is pull the clutch and oil pump off, and inspect that sidecase (if you havent already).

Speed buddy, the cases are split lol

its all in pieces!
I am going to go have a closer look in probably 20 mins.

one question, why would that explain the rod stretched?

and do rods/ crank assemblies usually only last like 2 years?.. I didnt put that much time on it.

haha....i was going from when you said the bottom end was together and it had side to side play.....i didnt know you tore it all down! but at any rate.....what i was saying was....IF the bearings were froze up, and it stopped the crank, if the bike was in gear at the time, the transmission would have tried to turn the motor over, which would have put alot of pressure on the crank/rod. but that couldnt be the problem....because if the crank wouldnt turn....neither would the rod....they would both stop at the same time. (and i think i confused myself with many others.)

[short4stuff]

lol ha .. well I examined the case/ bearing and I find that the bearing at one time did indeed spin lol. The tabs did get "ground" down abit but that doesnt not make up for the amount of side to side.

I dont think it ever "locked" up I just think the bearing seized at one time and the outer race turned a few turns while the engine was running.
Looks like I am going to need an inner left side case.

[speed20]

You are right.....it didnt have to lock up. You could probably find a cover on ebay....if not, Howdy can probably hook you up!

I have one as well
