[guest1640]

Hello to all.
Any advice on the oem carbie and re jetting to suit the 600 bore. What is that carbies limitations if more mods were introduced.  Ie. Cam, exhaust upgrades and tuned intake...
seeing a sigma kit on ebay. Has anyone used it. What are Results?
I am trying to avoid the expense of a minkuni or kehein.
thanks

I cant help you with the jetting as I dont use the standard carb, but any changes you make to the cam or exhaust will make a difference to the mixture. dont use a tuned intake or pod filter on these carbs, it will never work well, keep the standard air box but open up the air intake on the airbox. If you want to use a bellmouth change the carb to a slide carb you will have more flexibility then

Ok thanks Joolz.
Wasn't sure about the airbox. Vaguely remembered there was an issue.
Tm40 be enough you think? Allowing room for the big bore kit eventually.
Didn't you make a tuned intake at some stage?
