Hi guys. I have my 79 gs850 that I've been working on as a project. Recently got it running thanks to everyone here. Anyway, I decided to take the bike on a test run and discovered some problems. This morning when I first started it, it seemed to be running fine and idling on its own okay. Then...

Hey All, I recently bought a 2002 Yamaha 650 vstar custom and it has some issues. When I bought it I did some routine maintenance like replacing the spark plugs that were worn. The one had carbon build up which I contribute to the bike probably running lean. The other had what looked like oil...

Hello! I have a 1986 kawasaki vulcan. It wasnt running (assumed carbs) so i drained the fuel out of the system (it was pee yellow) and poured straight seafoam in the carbs to clean them. I also changed the spark plugs, and gapped them. I eventually got the bike running pretty well, runnjng on a...

Greetings all, THE BIKE: So, I have a beautiful blue Suzuki Marauder VZ800. 2001. About 268k miles. It has Vance and Hines debaffled exhaust with proper jetting as well, done by the previous owners mechanic. The pipes are wrapped and the bike does still have the PAIR valve still on (this may...

Hey, I have a 2007 Suzuki DR650 (completely stock!) 12,000 miles and I just cant seem to get it right! I have been fighting it for almost a year. so any advice will be much appreciated. It runs fine at low rpm, starts great but at probably 3000 rpm it cuts out and backfires and it does not come...

I bought a 1982 CB650 a week an half ago as the guy selling it couldn't get it running and he didnt know anything about engines. He also didnt want to even try with it. Said he had a new battery, but it must have froze over last winter in MN and it was bad. Replaced the battery. The guy also...

Hey there - I've got a 75 CB360T with one cylinder intermittently not firing (I think). I was riding home from work yesterday when the left side of the bike next to my leg stopped vibrating altogether (presumably the cylinder not firing). When I got home, there was oil accumulated on the air...

I just bought a 1989 Kawasaki Vulcan 750 yesterday for only $150.00!!! Everything seems to be working.... It starts and all the electronics are in order. That's all the good news. The bad news is...... When you are sitting on it the left side carburetor is backfiring and the right side...

This morning I started my bike in the coldest weather since I've had her--about 3C (37F). It took three or four 5-second attempts before I got ignition. On the 2nd to last attempt I had a backfire. I'm wondering if this means that the engine needs an overhaul. It seems to be burning oil. Even...
