stuttering fzs 600

[unfazed]

I have found over the years that the pluck caps loosen on the leads and can give a bit of hesitancy and sharpness is gone.. Many wrongly assume the caps give trouble and change them when all it needs is the following: Remove the caps from the leads cut a 1/2 inch off the end of the leads and screw them back on again. Water in the carbs can also cause the issue if the bike is used in the rain a lot or stored outside in the rain. Draining the float bowls and changing the fuel filter will solve this. Water lodges in the filter as it is resting on its side and can get picked up by the carbs when it hits the power band arounf 7000 revs
The above can also cause the odd backfire when starting from cold.
Check the TPS setting especially after balancing the carbs.
