Throttle slack

[The Pastor]

You mean it's running slightly rich or lean?

I had the sparkies checked out and they seem to be ok...

I'm kind of a mechanical n00b though so please correct me if you mean something else.

if you rev it in neutral, does it fall back instantly to idle or fall back slowly?

re reading what you posted it sounds more like a flat spot, does it happen only at a certain rpm?

Usually just falls back instantly though from time to time I have noticed it falls back slowly.

It's usually if I am sitting around 5-6,000 RPM and I try and give it a little gas around that kind of rev range. It drops in revs before it actually starts accelerating.

It could be the adjuster on the carburator end. It could also mean your fuel mixture is not right, you need to be running 96 octane fuel. Start by taking it all off and adjusting the throttle bodies then clean the carbs and re fit. Also take off your throttle and clean & lube the cable. Then take the bike out and thrash it to red line in first 3 gears (when was your oil last changed?). Then post up what you find. Injexted bikes are so much easier to diagnose.
