polishing motor help!

[michigan_rider]

hey guys, i am planning on pulling my motor out, polishing the cases and redoing my carb. and i was wondering. if i take my top end off to repaint it will i have to put a new piston in and resleeve it, or can i just take it off and repaint it and bolt it back on???

 

[bagds101]

you can take it off and put it back on. unless the piston is broke, cracked, has too much gap... then it needs replaced. also you will need a new head gasket.

if u are taking the whole cylinder off i would put rings in it just to freshen it up while its apart.

ok i want to remove my top jug, and take my clutch cover off for polishing and my stator cover off for polishing. do i need to drain fluids from my clutch? im new to this...

 

[slickerthanyou]

Yes! unscrew the drain plug, wait few minutes then you can remove the cover.

No, tip the bike on its side (gas off and hopefully low).
With it over on its side you can remove the clutch cover and lose no oil.
Haven't done it on a Blaster but have done it on many bikes including a DT200 which is pretty near the same motor.

I'd suggest the best quality 2 stroke gearbox oil (Motul perhaps?) for summer use.
It only uses a quart so price is not really and issue, is it?
I do use type "F" ATF when I have clutch problems.
Just don't ever use an "Energy Conserving" motor oil. It will fry the clutch.

Pull the jug and if it worked OK to begin with, it will work just as well with only a new base gasket. No need to undo the head.
While at it you may want to check the piston to head gap with some soft solder and adjust the thickness of the base gasket for a gap of about 0.040" or so.

Yes!! Once you pull that cover off the oil is just going to gush out. Drain it first.

Ummm, never tried tipping it over on its side?

Even makes it easier to work on.

I love your paint job 00blaster200!
