Hi, can someone out there please help me. I have a T500 that has the most violent deceleration surges you can imaging. The bike is perfect otherwise and I have no wish to let it go but can not live with this. New crankshaft and seals fitted. Cylinders rebored, new coils, plugs, points and condensers fitted. Timing is spot on checked both static and dynamically. Carbs are synchronized and checked with a carb balance. Have tried going both up and down plug temperature range. The slides do not stick and standard jets are fitted. Tried every setting on the air screws - my only clue is the further out it is the worse it is. Some improvement can be made by having the slides bottom out shut using extra springs and no tick over. Any sensible suggestions gratefully received.

Could be an air leak on intake like carb rubbers, but most likely you may need to change pilot jets,it sounds like a lean condition.I think standard are 30,you can try 32.5 or 35, on my 75 I went to 32.5 which solved the problem
