Wont attempt to start

SOURCE: No starter engagement 2005 Silverado 1100

I would seriouly look at the starter clutch, the 1100 yamaha cruiser motors are notorious for this problem way back when the same motor was in the viragos and the xvs 1100 vstars, yamaha have tried to fix the prob over the years but stillhavn't got it right. if it just spins and whirs without engaging the engine, but sometime will kick in engagement, it sounds like your starter clutch is on it's way out. they cost from yamaha around $450- 500 ea plus around $350 to fit you have to include a $30 gasket in all that.

Drain the carburetors. There should be a screw on the lower side of each carb float bowl. Remove the screw then replace it after the fuel drains. Is there any water in the gas? Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, (not all bikes have a water trap bowl). Turn the gas back on and wait a minute for the carbs to fill with gas. Install new stock NGK spark plugs and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetors from the engine.

FOR EACH CARB > Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

i have a 04 yfz 450 quad. the compression ratio like yours is extremely high. ive had my battery go bad and found that another battery other than factory would turn over the engine, but would not start. i paid the 100 dollars for the factory battery and it fired right up. because of the high compression you need a high cranking battery.

ALWAYS have a fire extinguisher on hand when working on carburetors.

SOURCE: 2000 yamaha vstar 1100 custom. starter problem?

I had the same problem 2001 XVS1100 Custom
this is a starter issue Over time the starter on this bike twists when its under a load.
Look at the two bolts holding the starter on if they are not straight across then its twisted. turn starter back in line with a pair of big channel locks and try to start this should do the trick if this works i would recommend taking the two bolts out and bend them back straight or replace and reinstall starter this should fixya problem

Hope this helps ...............Jimmyfixya
