Hi there, i have a 2005 CRF450X that runs 1 qt of oil(Putoline GP80 ) .
Today i was riding and the bike when i increased the RPM's in 5th would change to 4th. If i ride 5th at low RPM's the bike runs normal, if i increase the RPM's she changes automatically to 4th. The other gears run fine with no problems.
Any ideas what of wath is the problem?
In the last weeks the 5th sometimes poped out to 4th when i was wheeling and started to do more often when i changed from 14-42 to 15-42 gearing (she have 17' supermoto wheels).
I know 2005 have this transmission problem, so i think i will need to split the cases, any more things i should be focused since i have the cases splitted?
My bike is burning a little oil too, any suggestions in terms of Pistons or just use the TRX one ?
Can i ride the bike like this? I would like to ride some more miles until change the piston, i did 2200 since September, i was thinking in do 3000 and then change piston. The bike tops at 88mph in forth so i can ride just with 4 gears with no problem.
Thank you for the help.
