hugoverdog Posted October 14, 2008 Share Posted October 14, 2008 Hello, My bike (XVS Dragstar 125) has recently started losing power when I'm pulling away from lights etc. I'll explain what happens. I start the bike, in the morning or the afternoon/evening and let it warm up for as long as I can without getting really bored. When I pull away it moves but not anywhere near as fast as it should do, almost dangerously slow. The only way I get it to start working properly is by blipping the throttle and then it suddenly kicks in to life but even then sometimes when I change from 1st to 2nd the power can go and I lose acceleration, it feels like the fuel isn't getting through or something, this is really doing my head in, someone please help! Thanks guys! Link to comment Share on other sites More sharing options...
Ttaskmaster Posted October 27, 2008 Share Posted October 27, 2008 Check your carb manifolds. These are the black rubber tubes going into your cylinders from underneath the carbs. Mine are fucked - cracked and split to buggery - and I'm getting a lot of similar problems. Link to comment Share on other sites More sharing options...

Thanks guys! Have you checked the oil aroudn the bearings??? i got a 125 drag (2004) only had 1900 miles on it but the previous owner had left it on the kick stand for the guts of 2 years and the oil was all sitting to one side and this caused the bearing to seize up ...really affected the performance.......a lot like what you're saying.... this may be similar to ur problem.

crazy-welsh-biker Posted November 11, 2008 Share Posted November 11, 2008 hi, first i'd renew your oil, let the bike warm up before you drop the oil though, as the other guys said, check the carb manifolds and if they're ok you'll need to clean out your fuel system as it only takes a single grain of sand to cause this, gimme a shout if you get stuck Link to comment Share on other sites More sharing options...
