Hi. Your video is set to "private". So we can't see it..

corrected :thumbup1:

If valves are en spec, its probably pistonslap.

thank you all bier...I am pretty sure that sound's coming from right hand side,but i can not estimate,did it from barrel or from lower crank part...I will check oil pressure,oil road to head,valve clirence...and keyway,washer of counter balancer...

P.S sound after short ride... 27102012 - YouTube

Sometimes, when it first starts is there a single hard knock sound?

btw, do you have enough oil in that engine?


Vando ;)

No ther is not other hard core sound...it has correct level of oil certainly...and it is bradahl xtc c60 10w60 off road

I checked whether the oil comes up to the cylinder head ... and I checked the oil pressure ...and everithing is ok...Then I decided to take off engine from frame and check condition off head,barrel and piston...engine is on the table http://i1227.photobucket.com/albums/...ps01486210.jpg


I'd appreciate it if anyone would have to give me a link or send me the workshop manual to mail...:thumbup1:

This should be it.

Good luck

thanks...head and barrel are removed from engine...what I found:cam on camshaft are worn and with measuring i determine that is under tolerance(especially exhaust),one exhaust valve look like this http://i1227.photobucket.com/albums/...psefeedaf0.jpg

piston,piston pin,barrel,small end look good without some big damage...but I take them to some workshop on measuring...

And one IMPORTANT question...did compleat head from tt600e 2001(cylinder mark 3aj00,head mark 2kf) fit on 3aj with same marks...did there any difference in camshaft...i found one cheap...?

people...is this play of oil pump drive gear and axle OK ? or all must be tight?

Hi might be to late, but I had a similar problem with the noise prominantly on the right side cover. when pulled down it was a flogged out key on the counter balance shaft to drive gear. This noise was most noisy when reved from idle as this gives max movement on the shaft. brett
