nc35 carbs on a 30

[rgstu]

ive just fitted 35 carbs on my 30 tickovers a bit erratic and it doesnt rev cleanly after 5000 rpm any ideas ? im going to balance them tomorrow to try and clear it up a bit will the jets need changing ? posting.php?mode=post&f=24#

[Sligeach]

This is a mod a few lads on here have done. Not sure if anyone uses them on road bikes tho as they don't use the return cable.

I fitted rvf carbs to my roadie, work fine (you don't need a return cable - it's overkill).

I think you need to provide more info on your issue.

Needle type/height? Main jet size? Any mods? Etc...

[rgstu]

will whip them out this morning and check jet sizes and needle postion ps whats the best way to set the float height

[rgstu]

the rear jets are 118 and the front are 116 the bike runs fine up to 5000 rpm and then just splutters the needles are on the stand position do i need to go down some jet sizes ie to the standard rvf 108 ? ps the bike has a race can but im putting the standard can back on cheers

and ive also fitted a uk spec speedo which does not have the jap wiring will this make any differance to the running

[Drunkn Munky]

is the speedo conected? sounds to me as if the limp home mode is kicking. Take the rev limit wire from the ecu and connect it to 12v+. its pink i think

118 jets are a very over sized for a standard motor, back to standard or 110's

[rgstu]

the rev limit wire ? is this because ive got the uk speedo on . the jap speedo had a wire which the uk one didnt will this be part of the problem then is there a way round this cheers

[rgstu]

just read more into your reply the pink wire needs wiring up to 12+ that be direct to the battery then or any live feed

[Drunkn Munky]

yeah thats right, its pink on the rvf maybe different on the vfr, just splice it into a live feed behind the clocks.
