Re: smoking berg
oyk said:what really caused the smoking effect was :
"Hi Oyk,
An oval and / or tapered cylinder is considered normal wear. Heavy cylinder damage and / or piston seizure is likely the result of overheating and / or a lack of lubrication."
broken reed valve (who knows for how long) caused insufficient piston-cylinder lubrication because of the fact that when piston was moving to TDC it could not "suck" oil through the oil filter small hole located on the back+top of the crankshaft chamber.
is my theory solid? "No." am i wrong? "Yes."
"A Broken reed valve will over oil the cylinder"
anyway, the result was the cylinder surface to become slightly oval, so rings could not seal well(in fact new rings could not seal at all). "Lack of a reed valve over oils the cylinder creating excessive smoke and causing the bore to glaze upon which the rings will never seat."
i asked at my dealer for the price of a new cylinder and he said 590e.
is it good idea to have my cylinder electrochemically re-coated? "yes." (it is obvious that i don't know the right term) [
actually i send the cylinder today to a specialist here in greece to get it done.
he sais that he has the equipment, he needs 2 weeks of work but i simply think he sends it to italy
anyhow, the price is 220e and i get 1 year warranty.
anyone tried it? "Many times and with positive results in particualrly regarding Husaberg big bore kits".
does anyone has a link to somewhere preferably in europe that performs that kind of work?
Try this link:

Hope this helps.

thanks
thanks both for the links, i wanted to compare the prices for the electro-plating job.
thank you mr. dale for the education, i should have conclude that the lack of the reed valve would cause over oil the piston. when i opened it for first time the piston was soaking in oil...
my 600 will be ready 2 weeks from now, i haven't ride from february so i am a bit :evil: , you know how it feels i suppose...

bloody hell
its getting really boring guys......
today i picked up my electroplated cylinder, put the piston and rings in to measure play and ring gap.
the piston is a tight fit (the guy who plated it told me that he "gave" it a 0.006mm play)
compression ring gap is practically equal to zero at the top of the cylinder.
i put them on, started it and it worked great! no smoke and stuff.
after a while bloody smoke came out again :evil:
not as much as before but.........
went for a ride (about 10km long) and during ride it smoked just a little
now at idling it doesn't smoke but if i twist the throtle bit hard, a white cloud of pure cancer comes out.
my question is: if intake valve guides are worn and there is an axial valve play above normal, could it be the cause of such (with the above symptoms) a smoking?
which part gets worn first, valve or valve guide?
i pray to god that the smoking is just from that of the remaining oil at the exhaust, but i am afraid that it just ain't
any help would deeply appreciated

i think that 0.03mm is the maximum deviation for fe 600 (99' work manual). he told me 6 centimilimiters
any how i don't think it matters since the guy is a pro, and no case he would have done something wrong

Hi Oyk,
Give it a bit more run time to expel the oil which is sure to have collected in the exhaust system.
If the problem persists inspect the exhaust valve guide seals as they have been known to pull free of the guide.
Hope this helps.

Dale

thanks mr dale, the seals are new and when i looked at them they were not out of place.
i will ride it every day to work(12+12km a day) plus do a small trip to see if there is any progress
i keep on praying, but now that lineweaver said that it is most likely from the remaining oil, i calmed down a bit

A quick way to determine if the exhaust smoke is from deposits of oil in the exhaust is to check the spark plug.If it is burning oil during combustion it will be leaving deposits on the spark plug electrodes,if the smoke is coming from what is left in the pipe the plug will be running clean.hope this helps....nsman

I hope that the piston clearance is 0.06 mm and not 0.006 mm! Also, the compression ring needs at least 0.3 mm end gap to avoid their ends butting together during engine break in.
