Hi there. My bikes revs dramatically increase when bike is on an incline (front higher than rear). Even an incline as little as 10 %. I've checked floats and they are set properly and appear to cut off when perfectly horizontal.
This has been a long running occurance. This weekend I have stripped and cleaned carb, decoked front pipe, cleaned and repacked silencer, cleaned air filter, new plug and changed premix to Castrol power 1 racing. Running 50:1. I'm going to have a play with the air screw and get that set properly as I think it's running rich.
Any idea what could be causing this ? Obviously it was like this before I carried out the weekend maintenance. I just wanted to check everything was clean and functioning before I started looking for a reason for this increase in revs. I find if I stop for any reason on an incline I have to kill the engine as the revs pick up so much it annoys me. Bike runs perfectly albeit a blackish plug.
