Engine tries to stall.......

[Phatjap]

Hi
My bike seems to have developed a slight problem, its slightly different from all the other carb/engine/stutter related like problems so I am going to see if anyone has any opinions on it.

There are no stutters (except for the faintest hint at about 3.5-4k rpm) otherwise its smooth as silk, she starts well, runs great until I let the throttle off after about 5 mins of riding at about 50-60mph. It seems like its possible only running one cylinder, sounds sort of not right?! she tries to stall and and will do if I let the revs go below 3.5-4k.  If I rev and put the choke on it seems to stop it stalling but it means revving its ti*s off. If I go again back up to 60 it all seems well again.? Could it be being starved of fuel?
Anything I can try?
Look forward to any suggestions.

Cheers

Phatjap.

have you cut the rev limiter wire?
other thought is a plugged up Pilot fuel jet.

Hello

Did ask how to to cut the rev. limiter wire....? I know its yellow with thin black wire from TCI unit....but is that the IC IGNITOR box? If not, whre would I loccate the TCI?

the TCI and the IC Ignitor box are the same thing (behind the right side cover, behind the reservoir)

Thought it might be but wanted to check as I read on another post something about '6 pronged connector'  ?

Mine has 5 connections.

On the 6 gang plug that goes into the TCI, the Yellow/Black wire is the rev limiter.

the TCI box has two connectors on it. if I remember right,  one coming from the R&R, the other off the main wiring harness

stupid memory, he's right, the R&R wires go into the wiring harness near the back of the TCI.

I would not suggest plugging the R/R into the TCI.

Ok thanks, completed the inline fuel filter, completed cutting of rev limiter, tested bike and the problem still persistets, very very similar to this http://ridersofvision.net/forum/index.php?topic=5143.0 issue here.

Does anyone have any more ideas?

Getting rather annoying!

Have a good day.

completed the inline fuel filter,

does this mean you didn't have one previously? if not, you probably have a plugged or dirty pilot jet.

also, check to be sure the synq rod adjustment screw is tight, if not it could be way out of synq.  when was the last time you did synq them? have you checked it yet (and all the other 'basic' things?)

If the carbs are sync'd.Going after the electrics is the wrong way to go when you say it runs with the choke on ...means... It is a lean problem....lack of fuel.  = plugged jet or vacuum leak=YICS box or hose leaking.
