XT125r Crasher

Well I've had my XTr for nearly 2 years now, at first it seemed slow, yeah managing barely 60mph... but its had 2 years worth of thrashing now, and im afraid crashing too..which, albeit trashing the plastics a bit and not doing the headlight any favours (likes to switch itself on and off, currently trying to sort that) its increased the top end dramatically..Logic pls? Prior to accidents, top speed was 60 at a push.. Now on a good day she'll rev past 10k in 5th gear and cruise on up to the 75-77mph mark.. Problems i have with it atm though, are the STUPID petrol cap, leaks water whenever it rains, im about to go take my carb off and empty it, the fact it likes to vibrate all the bolts loose.. (lost my exhaust cover a few weeks back after literally 6hours earlier tightening the bolts on it) and the Idle.. I've set mine now to idle fairly happily at 1.6k.. BUT.. on cold days i have to hold in the choke for it to start..can be a bummer. Things you should try; Drop the forks through the handlebars about 13-15mil (1.3-1.5 cm), it dramatcially increased my handling and confidence in the front end.. and if your plain nuts.. bin it down the road, it might go faster lol.
