Got my jug off today...

[martinfan30]

Just ordered a window mod piston, cometic gaskets and V2 reed block from stewart today. So I pulled my top end apart and the top of the piston looked almost new, just a little carbon. Now for the cylinder pics. Tell me what you think, please.

shipped parts today..is the chrome flaked ..the stock cylinders are pron to the nikasil being thin,,,, i like max power

[martinfan30]

Below the exhaust port, there are some very, very tiny little pits. Around the top of the two smaller intake ports, there is a very small section where I see bare alu.

As long as there is no flaking at the port edges and no deep scratches it should be good.  It's hard to tell from your pics, need a bit more focus or a macro setting. You will be very happy with the windowed piston with the V2. Cam.

*** we posted at the same time.  You might want to take some good pics of ths spots you are in question and re-post them.

I can feel some extremely light scratches on the bore below the exhaust port. No bare alu. anywhere on the bore.

I'm unsure of my camera. I'll take a couple piston pics.

Just answered my own question I think. A spot the size of a pocket screw driver blade above the exhaust port shows flaking.




SOOOO.... What to do? Re-coat? Sleeve? Whats better, cheaper.. Sources?

What if I ran it on the new piston?? Things are tight, so I have to be careful, but I dont want to put together a grenade either.

Thanks so much fellas!

max power  replates 

[cbxracer30]

Eric gorr's forward motion [he used to own Max Power] or just send it to US Chrome your self , thats where both of them would send it to anyway.  Do Not send it to Langcourt I had them do one and only one had to hella-coil most of the thread in the cylinder. I've also heard good things about Millenium.

[martinfan30]

I got a good quote from Millenium today. 189 for replate. Theres no cracks or serious gouges, so I think that'd be all.

I think you are making a wise decision on the replate.  Run some good oil and you will have a nice bike that will last a long time. Cam.

Like Super M? Just switched to it, from Maxima Castor.

You are right, I figure its lasted 9 years and the wear is kinda minimal.. So a good o/h and good oil will at least last as long.

there is a lot  off difference in replating jobs that i have seen ..  i would stick with max power
