I was wondering what kind of power an 06' Trx would
make with a HCS2, Rossier full pipe, 13.1 wiseco piston,
an Intake (dont know what to buy) any sugeestions on that would
help too. an a green wire mod. maybe a port dont know...

What comp piston does the 06 come with?
it isnt the same as the 04-05 is it?
I thot i heard that the 06 came with a 12.1:1
piston an the 04-05 came with a 11.5:1 but the
hrc piston for the 04-05 is 12.1 :1 did i just
hear false info.

04/05 stock 10.5:1 (no comp upgrade with hrc)

06+ stock 12.1:1 very diff. piston design (06+ gets the crf type, very short skirt)

I went with hrc kit and rossier exhaust with k/n pro design intake, (havnt got it on dyno yet but im guessing 50hp)

I have an 06 trx with the full rossier system and have a 14;1 comp venom piston(great piston i might ad) and the stage 2 ht cams, port and polish with kibble white valves and springs and 1mm bore and i pulled awsome power.I,m a sand dune guy so i need the power. are u gonna stay stock bore. cuz the 06 already has a 12;1 compression piston.If youre gonna do all of what u want from stock then u will feel a big difference, probably 12-15 horses from stock with a pipe cams, air filter, and 13;1 piston and proper jetting, but if u want more power theres only bore after that with this quad.

then u can stroke it but i would do a turbo before stroking anything
