not reving out

[matslade]

right here goes, parked up pre winter everything five started up five months on and she stutters just b4 revlimiter everytime everygear mechanic cleaned and balanced carbs and changed plugs but problem still there he now says its a fueling issue and needs to go on rolling road. i was thinking the filter on the fuel tap? is there a rev limiter thing cutting in early anything else?

give your carbs a better clean . and give it a service oil/ filter/ air filter plugs\(iridiums) and some nice new petrol

Check air filter for mice.

No, I'm not joking

[matslade]

its about 1500b4 redline it does go on to the redline but stutters as though its struggling for fuel

[tony.mon]

Does it pop and bang a lot through the exhaust as well?

If so, check the vacuum take off bolt on the rear of the front head which should either have a cap head allen screw in it, or if it's already been modified to take a carb balancer should have a brass pipe poking out with a rubber pipe on, which should have its other end stopped up.

ah, when you cleaned the carbs, did you remember to reconnect the throttle position sensor

easily done though... just have a peep at the carb linkage on the right hand side, see if there is a connector hanging off.
also why did the carbs need cleaning.... if they were full of crap it can only have come from one place - the tank.
so it's possible that the carbs were cleaned and then more debris entered due to crap in the tank.
the only soultion to that one is clean them out again and fit an inline filter.
might be worth cracking the drain screw at the bottom of each bowl & see if any crud comes out.

were the plugs definately changed??? iridium plugs dont last forever!
if all else fails just take it for a dyno run & see whats going on with the fuelling
