  3. 82 GL500 Idle problem

    Motorcycle Repair
    I am looking into buying a GL500 but the guy selling it says that it has a clogged idle circuit on the right side carbs. Would this be an easy fix? Sent me a video of the attempted start, but he says it starts and runs, but runs at high rpm's. Decent bike at a better price.

    First Bike / New Rider
    Hi, I've built an old honda cb350 from a compilation of about 3 different bikes years 71-73. I've got pretty much all the kinks worked out of it. I'm having a problem with the what I think should be a carb problem. I get good power out of the bike but at about 4 or 5000 rpms in probably 3rd...

    Motorcycle Repair
    Hi, my 1985 Yamaha Maxim XJ 700 isn't running well. The outside two cylinders are firing but the inner two don't. I've sanded and exchanged the spark plugs but nothing changed. They were all running last week until I changed the oil and hosed it down. Suddenly, I have trouble. I've read...
  9. 78 gs75. Stalling/starting issues

    Motorcycle Repair
    I recently cleaned and resealed my carbs. The rebuild kit didn't come with the main jet o rings, so I picked some up at a hardware store. I'm assuming they are for plumbing. I also replaced the stock air filters with the pod style ones, and thus upped the main jet size as well. Now my bike runs...

  15. Possible carb/fuel problem?

    Pretty new on this bike so I am not familiar with too much on it. It is a 1991 Suzuki GSX750F, supposedly has the GSXR motor in it, but I'm thinking he just said that because they have the same motors as the late 80's gsxr's. Yoshi pipe and jetted. My problem is the number 4 cylinder. I've been...
