hey guys ! im kinda new to all this engine modding ....i want to put a 11:1 piston with hot cam stage 2 ...i already have the big 3.... i'm gonna be putting the piston before the cam ... just wondering if i need a new map for only adding the HC piston without cam ?... i heard that if you only but up the compression you can keep your current map !!... i know when i add the cam i will have to get a new one tough ! .... does anyone have maps for this setup ???

HMF full exhaust
Pro design intake with k&n filter lid off
PCIII
11:1 piston
hotcam stage 2

thx for your time
happy riding !!:rockon:

go with a 11.5 tech piston over that 11 to 1. and yes your map is fine without the cam, i would also look at a hc3 over the 2 and look at some porting when you do it

hi thx for your help ... can i still run pump gas with the 11.5:1 ??... or is it borderline ok ?... i have this quad for trail riding and alot for winter driving every weekend ... so i dont wanna build a race motor lol... i would just like something to give me a standing chance when i go at the drag races ... tired of getting smoked by tricked out 450's :thumbsdown:

also the hotcam 2 would be best for me to match my riding style ... i aint at the redline often
thx again for your reply

p.s. anyone have a map i could use with this setup?

Go with the HCIII, its not a rev cam- just a little better over the HCII. IMO the HCII is for stock compression bikes.

you dont need to have hd springs or anything with the hotcam, probably low to mid 50s would be normal i would think with your big 3
