Right ph4824,
I'm sure we have PM'd about this before?!
My experience:
New bike 0-500 miles, ran great.
500-3000 miles, after first service by Riders Bristol, the running went to shit. I reset TPS, and checked and reset the ignition timing which was slightly off. I still had problems. They had it back and changed the intake seals. Still had problems. I Checked EVERY electronic components specs and resistance values, and everything was perfect.
My fan was still coming on and had intermittent, low to mid rev issues.
I carried out the 'Breather Mod' but it made no difference, except it stopped pouring oil into the airbox.
3000-8000 miles, I carried out a HARD TPS RESET. (This is in the 'How To's' section). and it cured the problems instantly. If you want the full explanation why, pm me and I'll send you my phone no.
8000-10,000 miles, I've noticed the bike becoming more difficult to change up a gear at all revs. I adjusted the clutch cable to no avail. It also was not idling very well and adjustment of the idle screw made no difference. It was also 'Pinking' really bad this summer, Higher octane Petrol improved this, but it still 'pinked'. so I rechecked the timing. That was spot on, so I then tested the intake seals and found them leaking. I have just replaced them, and the bike is running perfectly, although it still seems to get quite hot in a mild ambient temp.
So, recapping!!!!!
1, Check / reset ignition timing, No cost.
2, Check and do a TPS HARD RESET. No cost.
3, Test the intake seals for leaks. No cost.
4, If still no success, test the specs of every electronic component.
My experience here, is NOT a faulty part, but that it's a part thats been fitted badly.
I hope this helps. L.E.
