| Your bike needs a damn good service Paulo.
Do what you can yourself, like the clutch, but it sounds to me like it could do with a good going over, carbs balanced etc etc. It will cost but I know you got the bike for a good price and it is basically sound. You will just have to stay at your parents for a while longer (I know I should have, the food was better)
I changed the gearing on mine (14T on the front) and it has made it much more rideable at low speeds. When I am on IAM rides I still have to use first gear in 30 limits to get the responsiveness I need. |
