It mounts on injection engines like a carburetor! A 28 to 30mm carburettor 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 carburettor whereas 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 is delivered complete with piston, seals, segments, axle, clips ... Of very good quality even see high, this kit remains an element manufactured in the Asian countries and is placed below the kits AIRSAL which is manufactured in Spain, although the finishing of the RRD kit is really beautiful, the materials too! The cylinder is made of aluminum for good cooling with an inner cast iron liner (unlike airsal which has a nicasil treatment). This makes it an extremely strong cylinder! The finish is excellent! The cylinder is covered with a gray metallic protection paint specific for temperature conduction. The high compression piston has a graphite treatment! We even deliver it with valve tail seals unlike its competitor AIRSAL. 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.

The cylinder indicates the 125cc displacement on its side, its actual displacement is 150cc.

 

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 ... :


14.5 to 16.5 hp from 7500rpm to 12000rpm
14,5nm 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!
