4rt Erratic Tick Over

Featured Replies

Hi,

Looking for a bit advice, not a clean tick over on my 4RT, its wandering .. high then low.. What could it be ?

Havent tried a new plug yet , but I've heard the gap on the plug should be closed up ? can anyone confirm ?.

It's fine once above tick over and revs normally ?

Does having the rear baffel out make any difference ?

:angry::P:D

No got all mine out tick over is perfect, so you can eliminate that.

Check also if you have a slow action throttle (white) or quick action (black), makes to improve things if you have slow.

Wrong way round :angry:

Black = Slow action

White = Fast action

I followed ferretflashers advice on the plug and also make sure I let it tick over for a minute or two without any throttle (to let the sensors settle down) .. it now runs like a russian ballet dancer on steriods ... Mint .... more fun to ride than any 2 stroke i've ever ridden (thats all of them) ;)
