bike broken . . . thoughts?
02/07/06 at 10:15:04

So, i'm riding my bike to work today, when all of the sudden it just dies. No special noises or anything crazy.

I didn't have much time to troubleshoot (had to walk the rest of the way), but I did a little.

Electrical seems fine. Lights work, starter works.

Here's where it gets a little odd. The starter works, but it doesn't seem to be catching anything. Just spins.

And, when i release the clutch but have the bike in gear, it's fairly easy to push the bike forward and backward. Not all the way easy like it is with the clutch in. But easier than i think it should be.

Did something break causing me to lose compression?

Any ideas?

Didn't see any oil anywhere. I looked for it.

Might be worth mentioning that I just did some repair work on the motor. Only has about 100 miles on it since i put the top back on it. I took the motor apart because 2 of the cylinder head cover bolts had stripped out. Used helicoils to repair. Just put a brand new head gasket on it.

Somebody not too long ago posted a question about engine head. Let's hope You are lucky and I am wrong .

You are describing the best case scenario. I have an engine like this that is sitting under the car-port.
Brocken valve,that cracked the piston , flipped and dug itself in the head. When You draw the line - bad cam chain tentioner, brocken cam chain, unusable head, piston, that needs to be replaced. All of this, because of the fact that the "genius" removed the air filter like a perormance mod and after that was cheap to fix the rattling cam chain.

The engine work i did was due to an oil leak. I thought i had the infamous plug leak, but as i got the motor apart, i found it was worse.

one of the long cylinder head cover bolts (which extends through the cylinder head and into the cylinder) was stripped. Most likely, someone worked on it before me, and overtightened it at some point.

So, i had to take the head off. I drilled and tapped the hole in the cylinder, and put a helicoil in it. Everything was go to go. I was able to put everything back together . . . torqued up fine.

Got the bike reassembled, and put 100 miles on the motor. Then, i was just sitting there yesterday, and it shut off with no warning.

ugh.

nope . . . no weird noises or lurching or anything . . . just shut off. At first, i thought it was electrical.

But, i looked at it more last night. It definitely has a severe loss of compression. I can put it in gear and push it easily. not quite as easily as in neutral, but very easy (not a transmission problem).

Maybe i'll get lucky at the problem is just that the spark plug came loose. heh.

Reply #10 - 02/08/06 at 11:20:40 If it ain't a loose spark plug, it may be a holed piston. Were you running a hotter plug than recommended? Good luck!
