Performance variator for a rare 1P57QMJ engine By rp62 (Read 2,359 times)

Hi everyone,
My scooter sells in Venezuela under the brand Skygo Elegance SG150T-8, but it really is a Lifan LF150T-9R. It is equiped with a 1P57QMJ engine and rides on 16 inches wheels. I found that it is very similar to Rocketa MC-12-150 which is comercialized in the US. As a matter of fact both have the same engine.
i need to replace the clutch which started to shown signs of wear at 2.500 km, but I would like to use a better quality one and by the way replace the variator. I haven't been able to find a performance variator, it seems this engine is a rare one. In fact it looks different to most 1P57QMJ engines.
I will appreciate very much any help on this matter.

Some of those scoots with a 1P57QMJ motors 16" wheels have a 250 CVT Setup with a 123mm Variator. Take a picture of your CVT. As far as mods to the motor not to many performance parts are available for that motor. The motor has a big valve head and it is taller than your regular 157qmj motor also has a longer cam chain.

Thank you Alleyoop. Picture of CVT with cover removed, right?

Yes and if you can remove the nut, count the number of splines too.

I have not seen any performance CVT parts for that engine . Does your valve cover have 2 bolts or four holding it on ? You can play with the roller/slider weights in your stock variator .

Here are parts for that scoot and motor:

Hi everyone, thanks for the help.
I'm sorry but I don't have an impact wrench or the tool to hold the variator in order to release the nut, so I can count the splines. However, I did was able to uncover the CVT and take the pictures attached in this and next post. I really hope it helps

Yea it looks like a bigger CVT setup.
Measure the Fan Variator it is probably 4 and a little over 3/4 inchs across.

Thanks Alleyoop. I'll measure the Fan Variator as soon as possible. After seeing the pictures, do you still think it is a BN157QMJ engine even though it indicates 1P57QMJ?

[alleyoop]

If you measure the Variator across and it measures abut 4 1/2 inchs or around 4 inchs then you can get CVT parts that are for 157QMJ motors. But if it measures almost 4 and little more than 3/4 then it has a 250 cvt setup. So measuring the Variator will tell all.

Hi guys,

I took some time today to measure the CVT components and take a look at the Valve Cover.

I measured the diameter of the Variator Fan, Clutch Bell and Clutch Pulley. The VF is almost 4-13/16 in. (122 mm), the CB is 5-3/8 in., and the CP is a little less than 6-1/8 in. I also checked the Belt specs which are 906-22.5-30.
In reference to the Valve Cover I saw it has four (4) bolts holding it.

Again, I will appreciate your comments and guidance after this info. I hope to figure it out after it. Here you have some pictures.

Thank you!

The CB(Clutch bell is 5 3/8 not 4 3/8) and yes that is a 250 CVT setup on that scoot.

Yes Alleyoop 5-3/8, my bad. Thanks!
