compression stuffed

I was referring to the ball hone specifically but any info regarding deglazing and honing without using high precision machines would be valuable.

 

sorry brad, I was responding to the post above yours.

Reason for not getting new rings is I was quoted something like $100 for a set of rings for one cylinder from bikebiz. didn't feel that spending $400 for total set of rings would be that great an investment. Still waiting on a reply from another place. What would you expect to pay for a new set of rings.

I've been quoted a second hand low km engine for $850 but who can guarantee I won't have the problems I am now experiencing. I hear what you are saying and it is common advice about the don't go cheap part. I will probably delay assembly for a bit longer then and think about it some more.

Now I understand what is meant when someone says it is not worth fixing up.

Probably my worst fear is that I spend a whole lot of money on rings, sleeves, machine work etc and end up with no or only slight improvement of compression. Maybe I don't have a choice about getting new rings. In it's current state the accelerated wear may render the engine unusable in a short time.

here's some low quality pics for people wondering what the inside of the fizzer looks like.

 

I decided not to do any improvements. Just got new gaskets. only problem now is heaps of white smoke (steam?) is blowing out the exhaust. Could this just be the oil that I put in the bore and piston rings to lubricate for assembly or is this signs of a larger problem.

another problem is the cooling system is overheating, after just circling the carpark a few times the water starts bubbling through the vent. Also the engine just seems really hot. I used only tap water, is that a problem.

worst case I can think of is that the head isn't torqued on properly so coolant water is getting into the combustion chamber and steaming up. and the combustion gases are getting into the coolant pathways and superheating everything.

engine sounds fine through everything and even started off the starter motor when cold which it did not do before.

 

thanks, the smoke is gone now.

 

after a bit more running. heat seems about on par with before. needle stays in middle to 3/4 range.

still can't rev above 10 000 consistently. sometimes if i'm in 1st I can slowly creep up to 10 000 and if it feels strong i can rev it up to 13 ish but then when i shift to second the engine immediately goes back to under 10 000 and jerks around.
