Your fuel petcock (on/off tap) may be restricting fuel flow and the carbies may need to be cleaned.
To maximise fuel flow thru a dirty fuel filter or restricted fuel flow thru a contaminated carby jet, disconnect fuel hose from tank and drain remaining fuel in carbies into a glass and inspect for contaminates. Take off float bowls and spray ($8 retail 400g aerosol spraycan carby cleaner) cleaner down fuel line/hose until it pours out of carbies. Allow to evaporate. Replace fuel filter (there may be a cylinder of white mesh gause inside of fuel hose) and check bottom of tank for rust, scale or debris. Try fresh fuel, new sparkplugs (0.8mm gap) and ensure choke is functioning correctly. Check camchain tensioner is not loose. Keep battery fully charged, replace if the bike can't achieve this when running with no lights..

Why would my mower engine surge at full throttle? What would cause my 26 horse twin to run normally for say 15 secs.and then dying out some to only get back to normal operation and so on and so forth?


This sounds like a clogged main jet. or else if it is an older mower, the jet is not sized big enough for the ethonal gas. Try thoroughly cleaning the carb and jets, or drill out the jet to the next larger size.

Hi, Mike_hall558 and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Float needle and seat sticking.
5. Float level too low.
6. Carburetor bowl vent line clogged/blocked/pinched.

4. Contaminated or plugged low speed system.
5. Enrichner valve not seated or leaking.
6. Leaking accelerator pump.

I have a 2008 KX450F. Starts on 1st kick when cold but really hard to start when hot. Also have trouble with the idle, it is idling very fast but will eventually slow down to normal idle if i let it sit...


There is no reason for the idle to take 10-15 seconds to slow to normal. perhaps you have a vacume leak. check all your seal and gaskets between the engine and the carb.also when it is running spray gummout spray or equivilent around the gasket edges between the engine and the carb, if the idle increases when you spray then you have a vacume leak. (intake leak). It may be that this is causing it to be hard to start when it is hot.(not getting enough fuel)

The transmission on your bike is not syncronized like a cars trans. When you are trying to shift from neutral at speed you must slow down to allow the gears to mesh. As far as having to rock the bike into gear sometimes, I have owned eighteen motorcycles of different sizes and makes and have had to rock all of them at one time or another to get them in gear. again lack of syncronization. It really doesn't sound as if you have a problem.
