It will be running lean at idle.

You can probably get better idle and off-idle performance by setting them to where they need to be.

Yes it has to be precise :P otherwise it'd be 1 and whatever you feel like out :grin:

It's not hard once you get it in your head

There you go.. as you can see, if your screwdriver is Vertical (|) you need to turn it half a circle so its' still (|) but upside down.. then one more of the 8th notches :-)

Good luck! You'll have it running in no time

A Maggot doesn't really count - it is a short and noisy can. We are talking 400mm+ for a proper sized long can.

A shorter exhaust length, in general, is more suited to higher revs and top power.

well my carbon fiber can now is probably shorter than the maggot due to my accident...and the maggot sounds good and looks awesome.... :mrgreen: is it a massive differance in power...what other mods can i do to this beautiful 2 wheel machine....

+1 on the maggot can, it's not far from being a straight through can and if your after more midrange your be wasting your time with this. But if you really must have one then im sure someone could advise you on a decent setup for running one although i doubt it'll give you much in the way of midrange.

Well....do you want more low end as you stated or do you want to piss your neighbours off and get annoyed with 110db exhaust all the time?

This may help, from another thread
RonniB wrote:35 engine and carbs, fit an ignitech cdi and hrc jet kit from Rick, get a TPS from cbr 400, tyga twin stack, some sort of under carb air tray and run the carbs semi-open (just a filter on the airbox baseplate). This is a high torque road setup, which is going to be just as smooth and fuss free as the original setup once jetting and setup is done.

And when you come to jetting, sort out your main jet first, then the pilot screw/jet and finally the needle taper/height. And use Ricks method of carb sync before you do anything with jets..
