  1. Honda SL125 will not go faster than 30 MPH

    Motorcycle Repair
    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...
  2. Honda S65 restoration - won't get past idle??

    Motorcycle Repair
    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...
  3. Tricky Issues, experts needed

    Motorcycle Repair
    Hello! :grin: I've got this '96 Bandit 600, andI've got some problems. The issue in itself is that when I idle it, it won't really run without stalling. So I turn up the idle screw under the carbs, which results in the bike idling at 3,5k rpm when riding (so when I pull the clutch it goes up to...
  4. Acceleration Hesitation

    Motorcycle Repair
    I have a 2008 Bonneville T100 (Carbureted). Recently after riding for a while, I will come to a stop and try to go again. When giving it wide-open throttle, it will bog down really hard for about 30 seconds and only go about 5 MPH. It will also backfire at times. Then after about 30 seconds...

  7. Dying at high RPM - Already Cleaned Carb

    Motorcycle Repair
    My Suzuki Katana 750 started dying when I cracked the throttle open and RPM's went above 4000. It would still chug along, but continued to get worse. I sprayed carb cleaner into the air intake while engine was running and the issue got a little better with dying (seems like not enough fuel)...

    Motorcycle Repair
    Hi all, Bought this bike last year, ran ok for a month, then I let it sit for a month while busy. Then it would start but take forever to warm enough to turn the choke off. Trying to use the throttle made it die. Tried it last fall before storing it for the winter and it would not start at...

  14. 82 GS850 carb swap. please help.

    Suzuki
    Story goes, I found a couple bad diaphragms in the CV carbs off my 82 GS 850. Those slides don't have replaceable boots and the diaphragms are prohibitively expensive (150+ per carb). My brother bought me a 79 GS850 with VM carbs on it but the displacement is different. (26mm versus the stock...

  17. 98 GSX600F Katana. Of course it won't start.

    Motorcycle Repair
    I just recently bought a 1998 GSX600F Katana for 500 bucks. Of course a bike sold for that little is bound to have some problems although I wasn't quite sure what I'd be getting myself into. I've done a bit of digging into this bike and as far as I (an amateur) can tell, it's nothing too...

    I recently bought a 1982 cb900f super sport. The bike was only 800 bucks running with a few hiccups, I couldn't pass it up. I noticed the other day that the warm idle reaches about 3000 rpms. Cold idle is about 1000. I don't believe there is a vacuum leak but when I went to adjust the idle...
