I was riding my quad yesterday going full throttle down a gravel road. When i let off the throttle to stop the quad died and now it won't start. I put a new plug in it and it didn't help any. I'm getting good spark and there is fuel getting to the carburetor but when i take the plug out after trying to start it it's bone dry. Anyone have any ideas?

 

Try puttin gas in it?Or maybe oil?

 

if your quad is a two stroke you probably burned the motor up! on 2 strokes the motor isnt getting oil if the throttle isnt on. i learned this from snowmobilers racing on lakes. if your going full throttle and just let off,the motor is starving for oil.if you hit the throttle a couple of times while your coasting it wont happen

 

Yea it's a 2 stroke. I hope i didn't blow up my motor but you could be right.

 

Sounds like you could have a broken reed petal. If this happens, the engine will not pump any air/fuel mix into the cylinder. It will just pump the air back & forth out the exhaust. That is the good news.
The bad news is that it will do the exact same thing with a broken piston skirt, which can happen if the engine gets oil starved.

If you want to check the reeds, they are between the carb and the cylinder. Not a big deal. If the screws are hard to loosen, give the head a sharp rap with a light hammer to loosen it up. Don't hit too hard, you are dealing with aluminum, just a quick, sharp rap should do.
The reed cage will be easy to spot. If nothing seems broken...there may be bigger problems. You didn't hear a metallic groaning just before she died, did you? If so, big troubles. If the reeds look OK & you suspect a piston skirt, or heard the screech of death, don't run it. It is possible to start it by pull cording it VERY vigorously, and it will run as long as it is kept wound out. This risks getting a piece of piston skirt between the crank & rod or crank & crankcase causing bigger problems. I speak from experience.

Thats the first time I hear this. Does that mean that every time I hit the gas and ride a few seconds at full throttle then let go, my engine is not getting any oil? That sounds too bad to be true...

 

I didn't hear anything out of the ordinary before it died. I will check the reeds tomorrow.

 

i guess i would do a compression check first. im not sure what its suppsed to be for your model but it should be at least 100 lbs.

 

I fit is a piston an it is from lack of oil the oil pump cable might have been out of adjustment. you can set it to run more oil at lower rr's I have 2 two storke polaris's an have never had that problem.

 

I checked the reeds, they were fine. I don't have a gauge to check the compression but i removed the spark plug and put my hand over the cylinder and turned it over. I don't know hard it's supposed to hit but the compression blew my hand off of the cylinder. I put it all back together and tried starting it again. It just backfired a couple times and that's it. Looks like it's going to have to go to the shop
