When I replaced the base gasket on my 08 TW200 at 6k miles, I discovered the cam chain guide was pretty chewed up!
It was through the buffer material and starting to touch metal. It was also throwing bits of hard black plastic debris into the motor.
I was hoping it was a quality control problem with just my bike.
Well tonight I tore down the wife's 08 to replace the gaskets, piston/rings, and check the cam chain guide...
It also has approximately 6k (6000) miles on it too. You know what I found? The same damn thing!
Now its got me wondering and a little bit concerned! Am I gonna have to tear the engine down every 6K miles to replace the guide?
The service manual states that I have to remove the Head and the Sprocket to remove/replace the cam chain guide. But if
I have to remove the head bolts, I'm thinking, I'll have to replace all the gaskets and stuff again, every 6K miles!
Does anyone out there know of any other way to remove or replace this part without taking the head off?
Seems to me, you could remove the left side cover(s) hold the CDI unit with a sheave holder, break the cam chain nut free,
tie the chain up out of the way, remove the sprocket, move the chain over to the side, pull the CDI off, remove the woodruff key, remove
the gear, undo the two bolts and wiggle it out the bottom????
Would I then be able to simply wiggle it back up into the cylinder? Anyone know if theres enough room?
I love these little bikes, it just seems like alot of work every 3 months!
Any advice or suggestions welcome.
