Your compression lost is right there in your pics. That's not a soft seize,right there is a a full seize.that's either from not enough oil or running to hot from compression or a combo of both. yeah i know that the compression is low on the 46mm bore b/c of the piston. But why would my compression ...

probably right. i just wish i knew what the compression problem is w/ the 51mm bore.



TJ

rattling noise could be from the piston being put in backwards. check to make sure you put it in correctly.

i was wanting to keep the bike running b/c i need something good on gas to ride around. so i put a 51mm bore on and i only have 75psi of compression.
I'm having some bad luck.



TJ

piston has some scratches. and jug has about the same. they are not very deep but they are there.

sorry guys, my two little girls weren't being so great yesterday evening so i didn't get anything taking apart on my back. so no pictures yet. I'm going to try to get it apart today.

Post pics of the piston and jug. If the bike died like you said what happened and there was a seize,there are going to be lines on both the piston and cylinder walls.if none is present, check the reeds,and crank seals for leaks.also look for any other leaks like at the head,head gasket,base gasket ...

well crap... mybe i should just put the stock bore back on.

dang. so my 142 from before would've been to high if i would have done the check at wot.

got ya. thanks for the info. will it be a lower reading when doing it at wot?

Greetings: I suggest you reicheck the compression holding the throttle wide open. If it's the same, and you're sure of the 142 before, suspect a crank seal, bad reed, or gaskets as Mike said. I bet the crank seal because it was sudden. The vac leak and lean-out could've caused the overheat and seiz...

If your compression dropped 30PSI, it's more than a soft seize. Time to dismantle and inspect, then find the reason.

i took everything apart after the compression test. rings, piston, and jug all look good. any suggestions on why the compression might have dropped so much?

I think i might have had a soft seize today. i was riding around for about 30 min or so and then my bike cut off. i tried to start her but she wouldn't turn over. when i kicked started her she turned over then i was able to start her. before this happened my compression was 142 now it is 115. what d...

I've been trying every hour or so....except when i'm sleeping.... for three days now .

the only way i could get ahold of them was email.

ok. i'll check the vari and belt tomorrow...
on a side note, i took my bike out w/ my gps today and i got 51mph on a slight down hill.
