Surging R80GS
HELP ! ! !
Maybe someone have had this problem before and can help with good information.
I have a broplem with terrable surging on a GS. The carbs have been rebuilt, meaning repacing of all rubber parts, floats, needles etc.
The problem only starts to hapen when you accelerate past 4000rpm in any gear. Below 4000rpm the bike pull very well with loads of power and is in fact very light on feul, but when you hit 4000rpm it just stop accelerating and surges voilently. When you have a bit of down hill and can push the revs up to 5000rpm it will start running smooth again.
Sofar I have replaced the needle nozzle with a 2.64 versus the 2.68 that was in there and have dropped the main needles with one notch to the 2nd possition.
The main jet is 135 and I am going to install a 145 but the main jet should influence the rev range for the last 1000 or so rpm to full throttle.
