tmac20031 Posted June 29, 2007 Report Share Posted June 29, 2007 (edited) The shee used to always surprise me when I would get on it but I think something has slowly gone wrong because It doesnt have that effect anymore... you know, that kick. It runs fine but damn, my cousins stock 450 just kicks my ass and I can never beat him; he always beats me by at least 2 bikes. I have noticed it but I guess I have been trying to convince myself that nothing is wrong. The only thing I changed were the jets, and I lowered them one size because of my altitude; I noticed the lag before hand. Any ideas?

tmac20031 Posted June 29, 2007 Author Report Share Posted June 29, 2007 would taking the airbox lid off be a bad idea? Quote Link to comment Share on other sites More sharing options...
theshee Posted June 29, 2007 Report Share Posted June 29, 2007 What are you mods?? 450s are running bitches stock, you will need some stuff to beat them. Quote Link to comment Share on other sites More sharing options...

Not much(at the bottom),but I would think that it would be enough to beat a stock 450. Quote Link to comment Share on other sites More sharing options...
theshee Posted June 29, 2007 Report Share Posted June 29, 2007 You would be suprised. My wifes bike is piped, coolhead, reeds and a timing plate and is neck and neck with my Raptor 700. I would get a coolhead, reeds, and a timing plate for a start. That may get you ahead. Yamaha has done their homework on the YFZ and raptor, they can be a handful to beat.

floyd398 Posted June 29, 2007 Report Share Posted June 29, 2007 You scared me for a second there. I thought that you were gonna ask where the kick start is. but anyway 'theshee' mentioned some pretty essential stuff there. Quote Link to comment Share on other sites More sharing options...

Yeah, I guess thats somewhat expected. I just feel like my bike isnt funcioning 100%. Quote Link to comment Share on other sites More sharing options...
XxMeltIcexX Posted June 29, 2007 Report Share Posted June 29, 2007 Have you checked your compression lately? Id start there, if your fine then you just need more like all of us!! Eric Quote Link to comment Share on other sites More sharing options...
tmac20031 Posted June 29, 2007 Author Report Share Posted June 29, 2007 What will fix low compression? Quote Link to comment Share on other sites More sharing options...
KaosBanshee44 Posted June 30, 2007 Report Share Posted June 30, 2007 Listen to theshee i was in your same situation when running with 450s but i added pipes and a few other things and i'm killing them. Ofcourse i have alot more done than just pipes but your best bolt on performance to start out with would be pipes. Quote Link to comment Share on other sites More sharing options...
fastbanshee8 Posted June 30, 2007 Report Share Posted June 30, 2007 What will fix low compression? A top end rebuild, I.E., new pistons, new rings, new gaskets, and maybe even boring it. If it's not ported, the time to do it, is when you have to rebuild the top end. Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted June 30, 2007 Report Share Posted June 30, 2007 (edited) Nothing is wrong with your bike, 450's are faster bolt on for bolt on. Go beyond that, and the shee starts the shine. stop all this compression nonsense and get a port job. You would shit your pants if you knew how much harder a ported shee pulls. get a port job(with supporting mods) lightened flywheel I was in your situation. I had t'6 pipes, noss head w/ 21cc domes, vf3 reeds and a few small other goodies. I was right behind the 450's like you are. I got a port job by flotek, sold my t6 pipes(to a fellow hq'er), got some t5's, adjustable timing plate, 20cc domes etc. While i was at it, i put a new top end in. You talk about haul some ass now! I havent raced any other bikes yet but i can care less if i am faster. I wanted a fun playbike and that's what i have. :ohmy: Edited June 30, 2007 by RagunCajun Quote Link to comment Share on other sites More sharing options...

What else you hiding under there? hehe But in all serious, I have all the stuff besides a port that these guys are talking about and I am still about neck and neck with piped YFZ's, But I weigh 250 if I was 160ish I would be walking them.

wood Posted June 30, 2007 Report Share Posted June 30, 2007 your mods say that you have pipes and jets so you should already have your air box lid off,all of the other mods will help alot but if you dont have a ton of money maybe start with a k&n,or new rear tires,that should help.
