What should the compression be on a blaster?

If the quad is really easy to kick is that a sign that it needs a rebuild?

The bike will start and run for about 1/2 a sec, but smoke comes out of the carb where it attaches to the airbox, is that a sign that the timming chain needs to be a adjusted?

Is it possible its just the timming chain and not that it needs to be rebuilt?

The quad is a 01 and was raced for a year or so.

 

Don't know stock but should light at anything over 100psi.
Most likely, but not always.
Blasters are two strokes. They don't have timing chains.
No. (see above)

 

I didnt even think about them not having one. I knew that, lol. So it must need a rebuild?

 

100 would be too low for a high comp eng, a standard eng should be110 if in good cond. if its 14-1 i would guess around 200.

 

The compression on a stock blaster is between 140-160 psi. If your trying to feel the compression by kicking it blasters kick really easy. I have a milled head and it kicks easy. While my 250r is hard to kick, you can't kick it with tennis shoes. If it starts on the first kick you probably have good compression. But I would do a compression check with a compression test. How old is the blaster.

 

My son's blaster had 135# of compression when i bought it new in 2002,at sea level.

 

ok thanks all.
