Description

Ideal in combination with a sport exhaust like the TURBOKIT and a gearbox output pinion with a tooth or two more as well as a good colder racing spark plug CR7HIX (SUMMER) or CR6HIX (WINTER), here is the 150cc AIRSAL kit! It mounts on injection engines like a carburetor! A 28 to 30mm carburetor can also accompany the beast but the origin is also suitable (we recommend increasing the main jet all the same to properly adjust the air / fuel ratio, during your adjustments, you can use the AFR POLINI to point the right AFR of 13 so have good performance without worrying about running too lean ). You should know that the YAMAHA engine equips a lot of motorcycles, but the RIEJUs work harder than the YAMAHAs! YAMAHAs are often equipped with a Ø20mm MIKUNI carburetor while RIEJUs have 26mm (VM26SS from MIKUNI). This is why with such a kit, a good carburettor of Ø28 to 30mm in DELLORTO PHF or PHBH can be exploited! The injection engines, they will correct the richness on their own thanks to the carthography and the lambda sensors.
