Jet sizes for mods?

Post by Thom » Sat Apr 30, 2011 10:54 pm

I'm wondering, if i'm to keep the standard carbs (which is what i intend to do due to lack of funds) what size jets would i likely need for the following mods/factors?

Running standard airbox with K and N panel filter
Running Scorpion race cans without baffles with standard downpipes
Live in England
Run 95 octane fuel

I understand i should get a dyno run or ten but i cant afford that either, so im hoping the vast experience of forum users can point me in the correct direction... Currently the jetting is standard as far as i'm aware, but i expect fuel consumption and performance could be vastly improved with the correct setup?

Keep it as is, TRX usually running rich....put it on the dyno to see it´s all good.

factorypro needles will help with the mid range hole if you use db killers.

:D K&N filter, Micron carbon race cans and standard airbox, uses standard jetting, I can swap cans for originals and it makes no difference.
