Hardy (and any other DR Doggzz)
With your experience with DR's - any idea why a DR would pop out of second gear ( it's a bike I'm thinking of buying...?). Would a worn chain/sprocket be responsible?
Any ideas?
A DR650 which jumps out of second gear points towards either a bent or badly worn left rear selector fork, a badly worn selector fork groove in the fourth driven gear (yes fourth!!!) or a badly worn dog clutch between fourth driven and second driven gear.
It could posibly also bae a problem with the selector drum.
I don't think it has anything to do with the claw which turns the selector drum. (This would be the only part of the gear change mechansism which is serviceable without a full engine disassembly.) A problem with the claw would usuaaly show with gears which don't engage and false neutrals but it would not be limited to only one (second) gear.
The bike jumping out of second gear has absolutely and most definitely diddly squat to do with the drive chain and sprockets.
