acceleration

Just another cabin fever diversion. The scenario is simple. You're emerging from a mild cruise toodle in a metro area, to the open highway. Or, you're wanting to pass around a slow truck. And, stay in 5th gear. What kind of acceleration can be expected when throttling up from about 45mph to...

I’ve had this bike for a minute now. I inherited it after a dude got it running for the first time since ‘91. I cleaned the carbs. First time I’d ever done that, figured out what jets were. It kept leaking gas everywhere. The floats were all messed up. I said screw it. I bought the keihin carbs...

Hey guys, I am stymied. My '81H has been running very well...for the most part. I switched from cone pods to unis because I was experiencing a little hiccup around 3300. Thought it was an airflow problem. Rode it a couple hundred miles and no significant improvement. The bike ran well...

Hey guys, I finally got my bike running-ish. I found out its a 77 xs650 D. My manual doesn't have much on the D model....But when I start it, it idles around 1200 and then starts to increase fairly rapidly. I have my pilots at 2 1/4 turn. The rest of the jets are based off the xs650C model...

I've got 77 xs650 and it recently started acting sluggish and misfiring randomly. It only occurs during takeoff in first and second gear. After I get to third and up it's fine. I'm still new to this and don't really have a clue where to start. I've done some searching but couldn't manage to find...

Hi, Can the Pamco e-advancer be causing random misfires? My bike has a sligh uneven idle problem..idles at 900rpm and at 1100 rpm randomly. On acceleration, the bike randomly misfires... And therefore The bike is impossible to run correctly. The first 100 meters the bike runs well...

Hi guys first I want to thank you for all your help with the electronics, I now get to start my bike on the very first kick. The bike idles fine, charges fine but when I try to go for a ride I can't get any acceleration, first gear feels week and I can't get it pass 40 mph. Has anybody had...

Ok, yesterday bike running great. Today it's a total 180. At idle the engine sounds fine, until I accelerate. If I accelerate slowly it picks up speed fine, but once I get on it just a little harder, it revs up high as if I was pulling in the clutch and doesn't go anywhere. This happens in...
