Where are some different places I can have this done? What kind of cost is it on a 4 stroke, Ive never really thought hard about it till now because I just rebuilt my 400 with an 11:1 wiseco and stg 2 HC and still wanting a little more without a new top end since mines fresh.

I think you are going to be spending a minimum of $300 - 400 on a p&p.

It is a long process, that has to be done with absolute precision, or you lack HP instead of gaining it.

he still doing P&P? I know he isnt doing pistons anymore.

[chronicsmoke]

I'm not sure if he is anymore.. I'm not even sure he'll do 400s..

A guy that is probably doing my 450 this winter is Dynamite in AZ, he seems to have very good prices and is a good guy on the boards, but I'm not sure he does 400s.. I'd go Sparks or CT for a big name 400 builder

I wish I could have snaggged a 12.25:1 pump gasser he (Venom) had for a while, they were supposed to be better than a shelf 13:1

You and me both. I sent him a pm on the org and he said he was sorry but he isnt in the piston biz anymore.

Real shame as it seems everyone has worked pistons for the R but they are not pump gas friendly. CP is about as close as you can get it seems to the 12:25:1.

Yah I'm thinking I'll run a 12:1 CP or a 12.8:1 JE.. 12.8:1 is getting close to making me uncomfortable though

If I want to keep mixing race gas 50/50 I could go to 14:1 :D:D

If I ever have one done, My choice 100% goes to CT racing.

They have been working on 400's since the late 90's... They KNOW what works!

EDIT: Or trinity.

Trinity also has awesome products.

Thats my issue. But with cam overlap I forsure could run a 13:1 easy-still makes me feel uneasy tho. Mixing or buying the gas is just an annoyance round here. Used to be able to get 100 octane at sunoco but no more.. I could run 100LL but meh Im not a real fan of paying absurd prices for gas. 93 is already 4.5/gal round here and I use 2 gallons every ride plus thegas to drive to my spot :(

Id also 2nd ct racing if rage cant do it, ct is the 400ex man.
