I have a early 04 trx450r.lots of hours but very well maintained.While having the head off for a valve job/port & polish I was going to install my Venom piston.The stock piston weighs 457 grams & the Venom piston weighs 377 grams(80 grams lighter).Some people say to run it & others say to have the crank balanced to the new piston.What is your opinion on balancing the crank???????????
(stock bore,3 ring,12.25:1,Venom (CP) piston) Thanks for any input!

I had no issues making the exact same change you are planning without rebalancing.

You are gonna be impressed!

I WOULD PURCHASE TH ROSSIER PISTON, GREAT PRODUCTS AND GREAT CUSTOMER SERVICE FOR SURE...SFRACINGONLINE.COM

Yeah,youll be impressed till the piston blows up....Should have just gotten a CP shelf piston instead....Just as good....Dont let the venom groupies steer you wrong...This should be posted in the venom section and not the Rossier section....Lets keep this section BS free please.....

I don't think RIDERED was trying to bring BS to ROSSIER AND IT WAS POSTED in the VENOM section and it had been posted for some time ,but the question wasn't answered until today . RIDERED just wants some advice from other engine builders BEFORE HE TEARS HIS BIKE DOWN . SO IF ANYONE IS STARTING BS IT IS YOU turbo

Then pick up the phone and call...Its a little disrespectful and rude to ask a builder about another builders product on an open forum for all to see...You might get a little more truth over the phone...

TURBO YOUR NOT JOE AND IF JOE DON'T WANT SOMEONE TO TALK ABOUT ANOTHER BUILDERS PRODUCT ON HIS SITE I'M SURE HE WOULD HAVE NO PROBLEM TELLING THEM SO .WHY BOTHER HIM AT WORK SO KEEP ON TRYING TO BLOW UP SOMETHING THAT SHOULD HAVE NEVER BEEN ANY OF YOUR BUSINESS SO REPORT BACK TO SHERIFF ANDY TAYLOR AND GIVE HIM BACK THAT ONE BULLET HE GAVE YOU
