Hi guys!!!
Next tecnical queshions in this season
During last whashing I saw big scratch inside the frame near the chain
Pix 1
Pix 2
I can think only one oppotunity to make it - when bike fallen while rides. But there are no scratches on the my new chain and on old original chain!! And no metal dust anywhere.
What you think about this? Where is the true??? :-)
On pix 2 you also can see chain slider (swingarm guard). Front end of slider very curved to the right.
Can it be the reason of whine sound on higher gears?
Some weeks ago I downloaded inglish servise manual and fide "interesting" note - chain slack should be adjust when bike on the central stand. And I tryed it. During my next ride I heared whine sound. My ride was 20-25km. Then I back my correct slack back but whine does not gone
I hope I did not kill my gearbox
