Low Compression

Well, I knew it was too good to be true. Got my bike home from the impound lot and drove like crap at low speeds.(see Wanted forum)

Pulled the plug - oily. Compression test - 60 dry and 95 wet.

Anything else to check before I redo the top end? Machine has 3250 miles now. Only 500 of them are mine.

inspect oil good, look for water or dirt!
if they ruined your motor in 300 miles they had to have dome something to it, either screamed it to death or sank it

Dry/wet results point toward rings.

The junkie drove it 300 miles on pavement, of which i assume was all WOT.

After he dumped my quad near Fargo he kept going west and was eventually caught after a high speed chase on a stolen motorcycle, in Idaho.

You might find a melted spot on top or side, of the piston, just enough to take out the ring seal.

At least you got it back. Anything else busted/trashed on it?


Did they hang the horse thief? That's what we need to go back to doing......

that's right public hangings and heck, lets sell tickets to death sentences being followed thru on,
as I gather in today's twisted world , people would pay good $$$ to see someone killed live??
and why not make some money back, after all the costs to tax payers to feed cloth and lodge these folks??
prison system is over crowded and lacking funding to hold them all, so?? could be a win win
and also MIGHT MAYBE< deter some from doing some crimes, knowing what will happen, and NOT just get free lodging forever!

we need a stronger justice system, the one we HAD< has gotten softer and softer/weaker and weaker,, its sad! IMO

Piston and cylinder look great. Never done a ring job but imagine it would be penny foolish not to replace the piston at this time?

Might as well while you're in there. Piston, wrist pin and bearing, circlips. I would hone the cylinder too because why not if its already all apart?

If you're going to have the cylinder bored, get a new piston.


If you're simply going to hone the cylinder, reuse your existing piston and put new rings on it.


If it were me, I'd have the cylinder bored with a new piston and rings. That way you know it's good.
