The lighter ones will let you Rev up faster.

Yea and the way my variator seems to act I will still have no trouble attaining full top speed.

Still on hold. Waiting for another CDI. The one I got from Miami didn't work. Ordered another one streight from the west coast.Could it be my voltage regulator ? The 12 gram sliders got here. Havn't installed yet.

Sorry to hear about the stator mix match it happens been there. Hopefully they gave you a refund.

No, I'm not dealing with the stator . I'm dealing with the CDI and the coil first.

Seems to have just been the coil and the fuse in the solinoid holder. It seems to run fine now with the old CDI unit. All 3 of the CDI units I bought on line didn't work ? Don't ask me ?? Sooo.. Put in the 12 gram Dr. Pully sliders and took her for a spin. Acceleration has markedly improved and yet my top speed RPM has dropped to 6000-6200 from like 6600-6800 But still 65-68 mph. So, about the only thing I can do now is get a shorter belt to take better advantage of my variator that has full movement now after my mod. The belt will move all the way out on my variator but needs to move closer to the center on the rear (clutch) to reach over range for better than 66-68 mph top end. And that is if I havn't run out of HP by then to do such with my oversized self.

I am not suprized that the cdi was your big problem. I would check out performance parts for buggies that use the 250 class cc variator and go for a performance varitor.

[/quo It actually came with an ATV CVT . It says ATV right on my stock CVT. I am up and running now and trying to actually raise my RPM per speed I am going. The 12 gram sliders actally calmed my motor down (RPM) at any givin speed. I am only at 6000 RPM at top speed instead of at 6500 where my peak HP is.

JCL MP250A Lihai 257cc powered / This is how it all ended up here. This info is not for a 50cc-150cc scooter. They are a different animal in some ways to the Yamaha 250 / Linhia powered scoots. I have come to the conclusion that my 257cc Linhia will not go any faster on the top end without a meaningful power upgrade. Like a "real" 295 cc (300) cylinder / piston change plus maybe a little upjetting ? It just dosn't have the torque in its present form to go any faster than 68 mph with my 270 lbs , head right up in the wind resistance situation. I don't care what I do to my variator it just can not change this fact. But I have learned a lot about what works and what is a waste of time. #1 Forget about a bigger or a performance carburator if you don't improve your flow in some meaningful way ie: porting your head and exchange some torque for HP , And get an open / noisy exhaust and and lets not forget a performance pod style airfilter, also more noise. Yes , your intake makes noticable noise with no airbox. " It will sound faster " with just a pod airfilter and a more free flowing exhaust, But in reallity the numberes will change no more than slieghtly if at all. But if you are young and like to be noticed this may have some value. #2 Variator changes gave" ME " (big and heavy) no more top speed. But if a rider is much lighter than 270 lbs. this is what you want to do. #1 On the variator improvment, Shorten your variator boss by 1 1/2 mm do not exeed 2 1/2 mm shorter than stock or your belt will almost climb off your variator at top speed. This will allow your variator to reach its full out high gear. In stock form they stop short of this. #2 on the variator improvement, Exchange your 14 gram rollers for 11 gram "sliders" This will give you everything this motor can offer (with the boss mod too) IMO. I have four 12 gram sliders and four 11 gram sliders. This is what I personally want because I am going to get more power in this engine in the near future. But number 2 will keep you in the higher RPM for maximum excelleration and number 1 will give you full top end capibillities. Yes, You CAN get the best of both worlds this way.
