There's a good chance it's a misfire caused by arcing through the spark plug caps. Very common problem, made worse when it's raining and you get water around the caps. Are you still using the original caps? If you run the bike in the dark you can sometimes see the arcing. NGKs are a good and cheap replacement for the originals. If you do a search on here you'll find the code for them. You can also trim the ends off the ht leads. They can corrode on the ends where they screw into the caps.
Thanks for the reply’s. With the TPS should I be able to get it on 5 k exactly? Seems to jump from 0 to 1000 then seems very sensitive to adjust? Also when I get it to 5 k it’s not steady? Cheers again
If you've balanced your carbs with a ropey TPS I think that may have put them out as well, maybe somebody else could confirm that though?I'm guessing if it's not running smoothly on idle then a carb balancing tool would be all over the place.
Tps dont change the balance of the carbs it only monitors the throttle position of the throttle how people thing it can possible change a manual setting is beyond me it only reads where one carb is to set the ignition timing nothing to do with the butterfly setting , you balance the carbs set the idle when its warm then set the tps in that order if your tps won't set then its faulty it should stay at 5 without jumping
when i last balanced my carbs i tried it with the tps at 5 then at 10 and at 0 made no difference to the balance
The TPS needs to be set before you do the carb balance and checked afterwards too.Replace the TPS and check the carb balance again.
