New cam

[Jnblaster05]

Ok i dont have much done to my quad motor wise but wanna wanna get a hot cam stage 2 with a full system pipe i currently have a slip on what kind of issues will i have should i geT ANYTHING ELSE with it what kind of pwer diffrence will i see any help would be appreciated its a 04 400ex

I wouldn't run a stage 2 with a stock bore/comp motor. Stage 1 would be a better choice. Stage 2 is more suited for 416 on up with high compression piston

[Jnblaster05]

Do i need anything diffrent with a stage 1 will i get good power or should i bore it out to a 416

[Old Head]

you can bore if you want but then i'd get the stage 2 but if you want just the cam then go with stage1 you should see a noticable difference in power down low through mid.

I think the next logical step would be an 11:1 piston and a stage 1 cam. You will notice a healhty increase across the board and it will make your quad even more fun to ride!!!

See below for my answer.

whats my stock compression at cause you say 11to1 i was curious what stock is

[capncharlie]

i could be wrong but i'm pretty sure the stock is 10:1

[lpmaster]

pretty sure stock is something like 9.1:1

[400eXr1d3rZ]

I believe it's 9.5:1

[Def-e-nition]

guys , how would one bump the compression ??

How Do you Lift the compression Besides Skimming the head ?
I would like to know .
Thanks .

[lpmaster]

a different piston, thinner head and/or base gaskets different cams can also play a rol in dynamic compression

[Def-e-nition]

I already have a stage 1 in , meaning my dynamic compression has probably gone Down , due to the longer duration .

ahh . So that means when comes time to rebuild , i simply use thinner Base gasket ,PLUS - I stick in a Wiseco high comp. piston .
Got it .

its 9:8:1

Stage 1 / 416BB piston / XR head gasket should do the trick. If you are interested in buying all of this at once I can help you out with a nice combo deal.
