Ideal in combination with a sport muffler like the TURBOKIT and a sprocket box with a tooth or two more and a good colder racing candle CR7HIX (SUMMER) or CR6HIX (WINTER), here the kit 150cc BARIKIT!
It mounts on injection engines like a carburetor! A carburetor 28 to 30mm can also accompany the beast but the origin is also suitable (it is recommended to increase the main nozzle all the same to properly adjust the air / fuel ratio, when you set up, you can use the AFR POLINI to point the good AFR 13 so have good performance without worrying about turning too poor ). You have to know that the YAMAHA engine is equipped with a lot of motorcycles, but the RIEJUs work harder than the YAMAHA! YAMAHA are often equipped with a MIKUNI Ø20mm carburetor while the RIEJU have 26mm (VM26SS from MIKUNI). That's why with such a kit, a good carburettor from Ø28 to 30mm in DELLORTO PHF or PHBH can be exploited! Injection engines, they will correct the wealth alone thanks to carthography and lambda probes.
Its diameter of 57.4mm you goes from 125cc to 150cc real torque and power. The original breech and crankshaft can be preserved without problems! This kit comes complete with piston high compression BARIKIT, joints, segments, axis, clips ... Very good quality, made in Spain! Mounts on the YBR, XT R and XT X YAMAHA, 4T 125cc air-cooled engine mounted on many other 125cc motorcycles. The compression ratio is also increased for more torque and power, use only SP98, more SP95. In relation to the AIRSAL, this kit has a piston, axle, clips and segments of better quality!
Original power on an XT-R or XT-X 125cc :
12.5hp at 8000rpm up to 11 500 rpm
12nm to 5500rpm
54mm stroke / piston diameter 54mm: 125cc
Carburettor origin Ø20mm
(versions like the RIEJU RS2, MARATHON ... Come out of origin 13 to 15cv because they have a more compressed engine and a bigger carburettor, generally Ø24 to 26mm like VM26SS from MIKUNI)
Performance can be obtained with 150cc kit, exhaust line ... :
15.5 to 18.5hp from 7500rpm to 12000 / 13000rpm
15,5nm from 4500rpm
Highly increased compression ratio, only SP98 should be used
54mm stroke / Ø 57.4mm piston: 140cc real
Carburettor Ø25 to 30mm recommended, if you reschedule / rectify the cylinder head, made to remove 0.30mm for more compression! You can retouch and improve (remove the defects or what prevents the passage) slightly the intake and exhaust duct, polishing for the latter! Exhaust line without catalyst and sport filter that breathes well recommended!
As can be seen, power and torque are available sooner!
