Just had a quick ride on my DT125R, first time I've been out on it.
The bike ran OK at slow speeds, not megga but smooth enough. At some point when accelerating gently it suddenly went mad & wanted to start pulling wheelies on me.
I'm not yet experienced enough to cope with it.
I'm suspecting the valve is pegged open, and I'd like to shut it back down. I've tried to find a post about pegging, but not come up with one.
I have no servo etc, so as I understand it the valve shouldn't move.
