Rossier and HRC Cam???

[Pred_003]

OK, so i recently spent a ton of money on my 450... got a new Rossier pipe, hrc cam and a completely different suspension set up..... Question is, I currently am running a stock cam and full big gun race exhaust.... The bike has a 180 main (I think) and must have a different needle cuz i have the stocker in the dyno jet kit i got with the bike..... Will i have to change the jetting and needle set up to match the new cam and pipe?? Bought the bike as it is now that's why i'm not real sure what is in the carb.....

Should still be the same, cams don't have much affect on jetting, if at all from what I have seen.

Yeah, a friend of mine changed his cam and I dont think they messed with his jetting at all.

i had a Rossier with an HRC cam and i ran 180 main, 50 pilot and an HRC needle with the clip in the middle. this was with no lid. it worked well. not sure what elev. you're at. i'm around 900 ft.

Think i'm about the same.. maybe 1000... think that's how my carb is set now... minus the needle... well see though ... thanks
