Syncing the throttle bodies

[humbos]

Is it a lot of hassle balancing the injectors without too much stripping down? Ive got some carbtunes and the Vara is a bit "Surgie" between 2,500-3000 rpm just thought I,d give it a go! ...Any takers?

I would be intersted to know if you can do this and how as well as my vara is pretty horrible on and off the throttle at low ish speeds.

Just never balanced injectors before, guess you must be able to but don't know how.
Just done my carbs but its a vacuum carb TA, made a difference, very easy.

I wouldn't say that, possibly that the need to balance injectors has never been an issue for anyone. I will have a look in the workshop manual later and see what it says.

There are 6 pages in the 2003 Vara manual I have on disk describing getting at the the throttle bodies, removing them and reinstalling. Access seems OK - tank and air box off, a few electrical things to disconnect, throttle cables to detach and then remove the throttle bodies. But, there is then a load of warnings about not dismantling the throttle bodies or adjusting anything as they are factory set and even leverage against certain parts or snapping open the throttles while disconnected can affect the synchronisation. This is a mechanical area I know next to nothing about but it all seems to be suggesting that the bodies do not need synching unless they have been disturbed in some way - but the manual does not go onto to say how to adjust. If ever I really feel the need for this it will be off to the dealers or a specialist.

Reading the rest of the section is like reading foreign language to me - how many sensors, valves, and electonic trickery does PGMFI need. I like and (mostly) understand carbs, but PGMFI baffles me. I just hope it is as reliable as electronic ignition has become (which I used to distrust as I liked my points and condensors).
