Does anyone know how much it will cost for a new piston.
Can you get a kit with all the gaskets, piston, rings?
I burnt the piston a bit and lost the compression.
Any information would be useful :worship: :bang:
I just bought all new top end components, they include;
Pro-X piston, rings, wristpin and circlips- $145
Winderosa top end gasket kit- $45
wrist pin bearing- $10
All figures are AUD$.
Try to go thru the manufacture direct it will be a little cheaper. I got mine thru Wiseco, just called them up and they sent it thru the mail it was considerably less.
If you contact Jeff Fredette, he will put together a kit of just the parts you need including gaskets. That's what he did for me anyway. I always feel better after a job if I don't have extra parts left over, if you know what I mean.
I was told by a bike mechanic that if the exhaust leaks really bad it will run too lean and that will over heat you piston. Could have also be caused by cheap 2 stroke oil. The bike ran fine for about and hour long ride then when we stopped for a while it would not start again. You could feel that there was no compression when you kicked it so I pulled it apart and found the piston has melted a bit and smeared over the bottom ring. The cylinder is ok just need to use some acid to clean the aluminum off, then scuff it up again.
Yeah I read that in another post. I will just get some marroon scotch bright and scuff it that way. I have had the cylinder measured and for the age it was suprising how straight it is. The taper was only two microns and the bottom end was out of round by 2 microns which is literally nothing. I also had the piston to cylinder gap measured and it was only .0023" which falls perfectly into the 2-3 thou tolerence. Ordering the parts got put on hold once I got the prices back from Kawasaki. 50$ for piston rings is rediculous!
