Bottom end you mean engine oil??Originally posted by GV27
I won't touch the everyday change thing - I had a CR250 and changed the tranny/bottom-end oil maybe 4 times in 4 years!
If yes,,you are crazy,,4 times in 4 years.
did you race the bike??
I raced mine and as its 125cc instead of 250cc i had to keep the rev up all the time and that made damage to my engine,i changed rings between 6 hours training and 1 piston for 3 rings..
