Mudguard bolt(s) sheared off in the bottom yoke? Nasty! Here is one possible solution.
(Preview)
I have a number of fork yokes that have come off TTRs that I have broken for spares amongst which are some where the mudguard bolt has seized into the bottom yoke and sheared off when trying to undo it.

A simple tip that I got from Steve at Totally TTRs. Slip a rubber glove over the air intake when you are doing a full power wash Depending on how muddy the conditions are that you ride in, it is worth occasionally taking off the side panels, seat, rear mudguard, tank, battery box and headlight to give the...

Morning all, Just wondering if anyone has any experience of successfully upgrading the suspension on their bikes? The front end tends to be a bit twitchy with the whole set up being very soft.

Logic says I should be able to join the two wires together and make it so it will start in neutral and in gear whether the clutch is pulled in or not. I’ve tried that as a temporary solution but the b...
