  1. 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...
  2. 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)...

  4. First Bike: 1981 Honda CM400T

    First Bike / New Rider
    I just now purchased my first motorcycle. I've been a long time scooter owner - yes, I know they are no where near the same thing - but there is going to be a lot to do with this bike. I know that I am going to need tons of help and I figure the best place to ask would be right here with you...
  5. Fuel type for Kawasaki Ninja 500r

    General Motorcycle Discussion
    Owners manual suggests 87 minimum (never seen less than 87 at a station anyway). Seller said that he was told 91 is what he should use at all times. Rumor has it that the higher octanes can cause build up in the engine if not required, I'm no expert, not sure if there's any truth there, or if...

    I recently bought a 1984 Honda VT500FT Ascot (my first ever motorcycle) as a starter bike. I rode it for 2 weeks (200 miles) and it ran great. I should mention that I have no prior riding experience or experience with working on motorcycles. Also, I made the mistake of filling up with old...
  8. There's alot of fuel additives out there.

    General Motorcycle Discussion
    I went to the store today to pick up a fuel stabilizer for the winter, and came across several different fuel or oil additives that claim to prolong the life of your engine. You know, "cleans your motor from the inside out." I don't want to throw something in my bike that will harm my...

    Hi all. I have an '86 450. Yesterday, I dropped my bike at a very slow speed... I was just pulling out of a parking space and flubbed a turn. Stupid, really. I wasn't even on the road yet. In any case, I must have knocked something loose... because about three blocks away, the bike started...

    Motorcycle Repair
    Hey all, I have a '75 Suzuki GT185. I'm kind of stumped as to where to begin to look for my issue. What happens, is the bike kind of lags when accelerating. I can barely maintain speed while in 5th gear. But when it is most problematic, is when I am trying to leave my driveway (onto a busy...

  17. Possible carb/fuel problem?

    Motorcycle Repair
    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...

    My bike will get up to 60 mph thru the gears just fine, but after shifting into 5th gear, the speeds begins to slowly drop to 50 mph and no amount of throttle twisting will accelerate the bike. This is recent and new as 70+ mph has never been a problem. I have had (professionally done) the...
