Art can, jets - what size?
 

Hi bike is standard at the moment, apart from Art race can it has the standard 137 main jets and 17 what main jet size would you recomend going up to ? from what i have read its best to leave the 17 slow runing ? sorry i know this has been covered before any input would be great regards pete.:confused:

Re: Art can, jets - what size?
 

It will almost certainly be right if the induction is the same (i.e same air filter)

Thank's Chris should i change the 137 jets for a little biger ? would it make much diference.

Years ago, I had mine dyno'd. Dunoo what jet size is in there now, but they're non standard, and I can't run the bike without having a butchered air filter, a standard one makes it run like a bag o poo!!

Re: Art can, jets - what size?
 

Dizzy yours has a different filter so is probably running in region of 150 mains.

Like I say, for stock air filter leave jets alone. More hassle than is worth whatever tiny gains are to be had.

virtually none on just a slip-on can, it's a noise thing; standard jets are fine.

Cheers Mark.

Thank you so which filter would be best to up the jets a bit, sorry i know this has been covered a million times but its new to me, or should i just leave it as chris said ?:confused:

Re: Art can, jets - what size?
 

Mine is a standard filter, with a hole cut out of the top.

If you are desperate to mess with something then find a BMC race RS and stick some massive jets in.

However for gains with stock exhaust system it is not at all worth the hassle of guessing yourself, or the expense of dyno'ing to suit. Just IMO, and I've done a few variations of this myself.
