http://www.akunar.com/PRO_PISTONS.htm Get a hi-comp piston with a little bigger bore from here for $35 and a Hi performance cam off ebay for around $50. Most shops charge between 35-60 bore your cylinder. Get a top end gasket set to for about $20 off ebay. That will give it some more bite. Lap the valves while your in their and might as well get a sanding bit set from harbor freight and clean up the ports. Check out my profile page for a similar build that I did for under $100 in parts including a Cyl sleeve, and new carb, and a 63mm piston that I put in an SL 100 that originally was a 50mm piston. Thats a big bore. That motor would run circles around a 200s. PM if you have any questions.

Lap the valves while your in their

Now I have been wondering about this... my manual says "NEVER" mess with the valves because the have a "special coating" and will fail "almost instantly" if you remove it.

who makes those pistons?

ATC350xr To answer your question is yes and no..... they have a stelite coating so you don't want to grind the valves like you would on a car. But you can lap them with some fine lapping compound from your local auto parts store this will ensure a good seal and does not remove the stelite coating. All valves should be lapped new or old.

Redskin- Akunar is the main company that produces these pistons. They sell to alot of other companies that rebox them and raised the price.
