I put the xr400 cam in it defiately feels stronger now I was wondering what jet changes need to be done.I am running a 42 pilot raised the needle one notch from stock and am running a 170 main right now I live in Midlothian Va. its right at sea level.Do these jets sound safe to be running it for now to fine tune the jetting or do I need to go bigger.It definately runs a hell of alot better than before and iI havent noticed any low end loss just a whole lot more mid and a pretty strong topend.Oh I ported the head a little not much just cleaned tyhe bowls up and did cut away some of the exhaust it is definately restricted but there were not a lot of casting marks or should I say they were not really bad at all.I only wished I would have ran the xr400 stock head gasket instead of the cometic head gasket Ive heard it will raise the compression a little but oh well.
