Yamaha R1(carbureted) Ivans Jet Kit

Part No. R1-9800

(For off-road use only)

This Yamaha R1 (carbureted) Ivans Jet Kit is the result of 8 months of combined testing. It is designed exclusively for use with a 4-1 (not 4-2-1) exhaust systems. This means that it is designed for use with Akrapovic race exhaust pipes or any brand Slip-on exhaust, including the stock one.

The needles included in this kit have 4 angles ground on them. After 8 months of continual development, these were the final design chosen. This is due to the fact that performance decreased when any change was made to them.

This bike was tested with numerous airbox modifications, different air filters and ignition advancers. None of which would outperform this kit with the stock air filter, at any engine speed above 4000 rpm!
NOTE:
Ignition advancers are not recommended unless you have significantly raised the compression!
