    Hello everyone, I have a 2000 kawasaki zx6r that has been sitting for 11 years. I have the bike idling but whenever I rev it, it holds steady at 4000-8000 rpm when I release the throttle. I originally thought this was a air leak somewhere yet I went back into the carbs I rebuilt and did the...

    Good evening. These are supposed to fit the empire keeway supershadow 250 (xv250 copy but with 2 carbs) but we would like to know what's the original model those are made for since I couldn't find any info about a xv/xvs250 with dual carbs. :eek:

    Over the winter I put a jd jet kit and a pipe on my drz. First I went to start it and the battery was shot. I replaced the battery and it took ten minutes of cranking before it finally fired up. It needed throttle to idle and when I started driving it died a couple times but once it got warm it...

    Howdy, newbie rider here with bare minimum mechanical knowledge. I've got a 1981 Yamaha xj750 Seca. She broke down a couple months ago because of clogged carb and air filter. I replaced the air filter and cleaned the carb, doing my best to be very careful but I must've done something wrong. I...

    I have an 08 hyosung gt250. I got this just as a bike to mess around with. It starts up perfectly fine but it dies around 2/3 throttle, around 3400 rpm. I figure it's the jets because it did come from a different state. My current elevation is 4500 ft and temperature is between 60-95 so if...

    Hi everyone. I recently temporarily fixed a severe bogging problem (solved by changing inline filter) that wouldn't let me go past 50mph, and it would barely get me up there. However, now the problem is back and much worse. The motorcycle runs for 5 minutes with full power, then starts losing...

    Sooo.. not sure where else to ask and I realize it was stupid of me, but here goes.. I had my bike (1996 Cbr 600F3) running but the idle was a little off. I got a manometer and hooked up the vacuum lines. It wasn't terribly off, but I tried to adjust it just a bit to get it closer to perfect...

    Hello everyone, I just wanted to share how I was able to remove the the air screw that broke off in my 1978 yamaha XS750 carburetor. This is a common issue according to the other forums I've read. I purchased this bike for very cheap since it was not running. I purchased a carb repair kit and...

    Hello all, I recently bought a 1971 Suzuki TS185 to fix up and sell. This is my first project of this sort. when I kick start the bike (no push start) it starts up straight into full throttle, which is absolutely terrifying. I have to turn the key off to stop the bike immediately. Yesterday, I...

    Hi folks, I have a peugeot elyseo 125 that I am trying to improve. I am opening the bad boy to disassemble and clean the carburettor (first time, I am a noob), and I am having problems in disconnecting the carb from the engine. The tube connecting the two parts is tightened by a iron ring that I...

    I recently purchased a 1971 Honda SL125 with a few issues. The first issue was that it would not run worth a darn for more than 45 seconds. I determined that the spark plug cable was not attached to the spark plug well enough. After looking at the spark plug, I decided to install a new one...

    I'm restoring a 1965(?) Honda S65 and I'm 99% complete. As always it's that last 1% that is the showstopper! :sad: I have it in with a mechanic at the moment and while it starts easily it won't go past idle. When he turns the throttle the engine noise goes deeper as if it's getting ready to...
