thebrittishguy Posted September 23, 2009 Report Share Posted September 23, 2009 (edited) hi all. i have the carb sync tool and started my banshee today to sync the carbs. both dots line up at WOT on the sides of the carbs. they both look in sync at idle (just an observation) when i put the carb sync tool on the left one it has a decent air flow reading of 7. the right one has a reading of 1 clearly not having the "sucking" force of the left. i have set the cable and top of the carb on the right one and if i go higher then it affects the revs (higher) than the left but the air doesnt increase to anywhere near the 7 mark even when the revs are higher than the left...... any reason why this might happen? is this normal?? (i dont think it is having had a look at the youtube video showing how to use it) Edited September 23, 2009 by thebrittishguy Quote Link to comment Share on other sites More sharing options...
bbcmudtruck Posted September 23, 2009 Report Share Posted September 23, 2009 Is the carb pulling 7 at idle? If so, adjust the carb idle screw. Unless you have tors, in which case you need to order a $40 kit and get rid of them asap. Quote Link to comment Share on other sites More sharing options...

Unless you have tors, in which case you need to order a $40 kit and get rid of them asap. if you see my signature then you will see that i have tors removed. its not exactly at idle but at just above idle the left is at 7 and the other is at 1. just showing the difference at the same rev state. where are the idle screwson a carb with tors removed? all i have is the air screw which is at 1.5 turns out on both......

sleeper06 Posted September 23, 2009 Report Share Posted September 23, 2009 Did you ever drill/tap a brass idle screw in the side of each carb?If not thats your problem your half removed Quote Link to comment Share on other sites More sharing options...
papa_smurf49319 Posted September 23, 2009 Report Share Posted September 23, 2009 Yes you shoulda drilled and tapped for you screws on the sides. X2 Quote Link to comment Share on other sites More sharing options...
thebrittishguy Posted September 23, 2009 Author Report Share Posted September 23, 2009 Yes you shoulda drilled and tapped for you screws on the sides. X2 Anyone got a tutorial or a link to a page that shows how to do this please? And will this be why the left carb is sucking more air than the right at any given rpm? If not what could cause this when the slides are pretty much even looking with the eye? Quote Link to comment Share on other sites More sharing options...
bbcmudtruck Posted September 23, 2009 Report Share Posted September 23, 2009 The idle screw will only effect it at idle obviously. You will have to adjust the carb tops to get them synched when you have the throttle pulled. Also your signature doesn't show up, so if you want to be a little prick I won't help you.

shee4speed Posted September 27, 2009 Report Share Posted September 27, 2009 I am curious if you noticed a big change after the repair.Is it running better now? Quote Link to comment Share on other sites More sharing options...
thebrittishguy Posted September 27, 2009 Author Report Share Posted September 27, 2009 I am curious if you noticed a big change after the repair.Is it running better now? i didnt run it or take it for a run when i had the above problem, i just thought rather than damage something, check with the HQ and try fix it before riding. now it is lovely thanks, it just feels sometimes in top end if i give it gas that i hear the revs but dont feel them as hectic as i used to. im thinking maybe clutch adjustments? i have a RD 350 motor here which have jugs that are bigger bore, but my current ones are ported, would you reccomend leaving the ported in vs the bigger bore. the top of the RD pistons say .200 where my current ones are .100. been thinking if its worth swapping them or not. also would the RD gears be any benifit? i see below the waterpump that there is an extra unit on the RD that the banshee doesnt have, what is this and what does it do? thanks again for the info and help Quote Link to comment Share on other sites More sharing options...
