doesnt feel liek i have much compression

[sweetshee4312]

i was just woundering, when i kick my shee over it doesnt seem like it has much compression, but when i cheak it it looks fine, this happened after my rebuild, before it seemed like there was more to push againt, is it ne thing to worry about or should i just forget about it.

[SICK BOY]

Are your plugs tight??What psi are you pushing?

[sweetshee4312]

110 in each cylander

[Banchetta]

thats not much unless your up there in elevation. You should be around 128psi at sea level...

That does sound a little low but not enough to tear it apart. If it runs good then I wouldn't worry about it until there is actually a problem. If you're having trouble getting it started, loss of power, etc..then I would look into a rebuild.

[sweetshee4312]

it is hard to start, sometime i gotta take teh plugs off and put a dro of gas right into the cylander, but i just did a rebuild liek 5 hrs ago....and passionre bored and sent me the pistons, casue i got it ported at the same time

[2stroke_addict]

could be a crankcase leak !

[sweetshee4312]

it does not burn any oil though

[SICK BOY]

Do a leak down test.

[Banchetta]

I agree, do a leakdown test..

Sweetshee, your motor is running at 197 degrees exhaust duration and without smaller domes , approx 19's or 18's, the motor is going to read low on compression. 110 in my book is near non-existant compression. Your giving up a ton of power in the low-mid area at those numbers. If the motor idles smooth and low(near 1000rpm) once running and warmed up, the chances of a substantial air-leak in the engine are minimal...Jim
