    Hello, I have a Honda VT 250 which has got a dual carb setup. We took it apart today to see what's going on as the carbs didn't want to balance. We noticed that each carb has different main jet sizes. One that goes to the front cylinder had size 92 & the rear cylinder carb had size 90. We...

    Hi guys! So I posted recently through my top end rebuild and I'm damn near done. I've run into some snags though and could use some help. I called all of my local shops, repair shops, muffler shops, restoration shops, and even some friends but I'm on my own. Shop were all full or not in "Vintage...

    Hey guys! New here! Thanks in advance for anyone replying! Been doing all my own work on an old sporty that was given to me. All that’s really left is to get the damn thing to run properly!

    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...

    I have a first gen Honda Sabre V45, when started the rpms immediately jump to 4500 and stay consistent. I messed with the idle screw and the fuel/air adjustment screws and nothing changed. I think it may be the throttle getting stuck but I lubricated the cables and the spring seems to be...

    Hi all, I've recently started building a ninja 250 go kart, have got it running running fine, but have run into an issue, when I rev the engine it revs out fine but is very slow to return to idle, 15 seconds or so. I've sprayed starter fluid on the carb boots and this does rev out the engine...

    I have a 1981 Honda cb650. I have cleaned the carbs, checked float heights, and installed new needles. I can't get the bike to idle. If I choke it, it will stay around 3000rpm then shoot up to 5500 rpm. And when I push the choke in, it dies. I checked the temp of the pipes and the two on the...

    Hey guys, I am having some trouble with my carbs. I just took them apart and cleaned them, and have had trouble with them since reinstalling. When I start my bike with the petcock in the "off" position (starting the bike with just the fuel in the carbs), it idles perfectly. When I start my...

    I recently bought an 81 Twinstar to go to and from work. I am currently have the issue where if I hit the throttle somewhat hard, it will immediately bog out. If I just accelerate gradually it is fine. After I cleaned out the carb I noticed the pilot screw was tightened all the way, I backed it...
