Blaster compression problem

[mall0y]

Hey guys, I ran into a little problem with the blaster the other day and I just want to run it past some people to get an opinion on what it may be. The last time I drove the blaster was a couple days after x-mas. It started up on the first kick and ran fine. It sat ever since because I was waiting for the title and registration to come in.

When they came in last week I went out to ride the bike and it wont start. It's getting spark, fuel, and when I went to check the compression is when I ran into a little problem. When I did the first test the compression seemed fine. The needle went to 127psi so I let the pressure out of the guage and tried again. This time the needle went to 127 and started to drop. So, I tried it again. Again, the needle went to 127 and then began to drop. Each time I did this it dropped faster and faster. So, obviously I have some kind of leak.

Could it be the rings? Possibly a gasket? I was going to pour a little oil in the sparkplug hole to see if the oil would help the rings seal and hold compression but I didnt have any extra oil at the time. So, what do you guys thing I should do? What do you reccomend me checking? I'll tear it apart if i have to, i just want to get this fixed.

Thanks

maybe its your compression gauge

sounds like a bad check valve in the compression guage. you need to check cylinder leakdown with a leakdown guage set.

I thought that it might be the compression tester but that doesn't explain why it wouldn't start...

wet plug?? geting gas 2 carb?? dirty filter and/or carb?? its a blaster??? im da man -yes

[mall0y]

Plug was fine, gas is good and getting to the cyl., air filter was just cleaned, and i just put a new plug in it...

My dad's blaster did that after his sat for a while. It would not start unless you pulled it off behind another quad. He finally listened to my brother and he turned the pilot screw on the carb in a little and it fired right up. It's been fine ever since so that could be all you need to do also. Hope this helps.

hey do you mean pilot jet or the pilot air screw
cause i think that might be what i need to do

[mall0y]

nevermind guys, rings are shot. i tore her apart and it looks like the crank bit the dust. theres wayyy to much play, which in turn i belive caused some piston slap and you know how that goes.
