Thanks Carl, I will save these procedures and tips in the appropriate folder for future use.cybercarl wrote:You have started already..... First and foremost is the timing and Valve clearances. I believe carb farts occur during the Valve overlap period and the scavenging effect causing intake reversion. More of a problem with bigger carbs at idle speed/low down revs.
The next thing is to move onto Carb tuning. Carbs should be dialled in according to the timing of the engine, including the intake and exhaust systems hence doing the timing and clearances first. Carb farts can often get confused with a lean condition, especially within the Pilot circuit including the correct adjustment for the fuel Mixture (fuel screw adjustment). You will find that a Carb sync/balance, then TPS adjustment and then another Carb balance/sync to finish off will all help.

As you know I already have the carbs off the bike while I am doing other stuff to it. Is there any point in checking the resistance of the TPS while the carbs are on the bench? I notice in the article it said to tune and balance the carbs before doing the resistance test.
Thanks
