badbrad Posted June 22, 2009 Report Posted June 22, 2009 this weekend I took the bike out. and it was very humid out, so I thought that and a minimally dirty air filter were my problem. I lost to a lt450r in drags and I knew something was up (mainly cause I always stomped him). well, I just discarded it all and blamed it on the humidity. now, two days later i get it out, clean it, clean the air filter, tighten the chain, etc. and take it for a spin. When I get on the gas its weak as hell. The top end acts like it has a rev limiter on it. It falls flat on its face basically through the whole rev though. The bottom and idle feel really boggy and un responsive. Now heres the specs 2004 on the stock bore and pistons (which im hoping you guys will say it prob needs rings) 2 into 1 toomey filter, t5's, +4 timing and thats it. Im a weekend rider and dont even go every weekend. Had the bike for almost 3 years. .. 2nd owner. anyone with any ideas? Quote
Sandfrk33 Posted June 22, 2009 Report Posted June 22, 2009 Compression test should tell you for sure. They should be within 10% of each other. 120 lbs is around normal for stock. Quote
THE GRIM RIPPER Posted June 22, 2009 Report Posted June 22, 2009 Coulda just fouled some plugs budd... Throw some old ones you probably didnt need to change in there and have a go. Quote
black sunshine Posted June 23, 2009 Report Posted June 23, 2009 Did you have the mains dialed in? Could be a little rich in the hot&nasty. Also sounds like a stator problem I had with my R, with the rev limiter shit :shrug: Quote
Onesickcrewcab Posted June 23, 2009 Report Posted June 23, 2009 Heres a stupid question. But does it rev at all? Does it feel like a tors problem? Quote
badbrad Posted June 23, 2009 Author Report Posted June 23, 2009 the mains are 280 and they have always been fine in the hotter weather. yes it revs and the tors is removed. i just switched plugs and no change.... Quote
badbrad Posted June 23, 2009 Author Report Posted June 23, 2009 that is my next thing im going to check. its 93 mixed properly, but i guess there is rumors going around town about our station having shitty gas. say for example i paid for 93 but got 87, would this cause my problem? I am really hoping this is it. It dont seem like it could be anything else. I mean, i would be floored if there was dirt in my carbs because I keep it real clean and sealed up good too. Quote

Are you running outerwears? If so, pull them and go try it. Seen it in the shop too many times. They are crap! B Quote

With as many people that run these and don't have problems I hardly see this being his issue. Maybe really dirth outerwears/filters yes. Quote
blowit Posted June 23, 2009 Report Posted June 23, 2009 ?? With as many people that run these and don't have problems I hardly see this being his issue. Maybe really dirth outerwears/filters yes. Bet on it. I have seen probably 50 bikes in over the years because they just lose power, jetting is off, etc. People clean the pre filters but do not blow air through them because it is a no no for the gauze filters. Those pre filter pores will plug up easily. Foam filtration wins hands down. I will admit the outerwears look better though... B Quote

B I am using an outerwear, but I just cleaned it well, and it was only on its 2nd use. Also, it ran fine with the old one before, the filter is completely clean and it still did it when I ran with no filter at all. Quote

Lots of possibilities.. :biggrin: Quote

badbrad Posted June 23, 2009 Author Report Posted June 23, 2009 brand new reeds installed correctly, carbs are clean as a whistle (i know dirt could still be in there), no leaking antifreeze. no idea what you mean with the piston, but I would think it would affect performance everywhere if it was a piston problem?
