Toomey jet kit

[Zwiser]

Is the Toomey jet kit worth buying for a t4 pipe? is it better than just picking up the jets at the dealership? What kind of needles do they come with?

 

Also would it be a good thing to use 27.5 pilots?

Jet kits are not going to get u dialed in properly.

so i take it there not worth it so... what kind of needles do the use because ive heard people saying that the needle removed a flat spot and others say the didnt need the needles from toomey.

 

so should i just get 270-320 jets and do some plug chops.

 

and on to the pilot, since im changing the airflow out of the engine shouldnt i compensate for the increased flow, by riching all the jet areas pilot, needle, main?

mikuni carb's rely hevily on the needle, and main jet to do the jetting. in my experience i have been able to get them to run ok with stock needles and 25 or 27.5 pilots and from 280-340 mains. the toomey needles are excellent if your going to keep the stock carbs for a while i wouldnt hesitate to buy the jet kit they offer. the needles are custom cut ( or at least the ID numbers are taken off) so unless some one has measure'd the tapers and tried to match them up to a mikuni guide. not sure if you could find them seperate. the kit is pretty resonable anyways. the mains that kit comes with you will probably use.
