Need a replacement variator for my worn stock variators on a '95 and '99 Yamaha Jog with stock 1E40QMB engines. Sticking with a stock cylinder on both of them for now, but may do a pipe and other small performance mods. I don't want to spend a ton and prefer to stay in the neighborhood of $50ish. Any suggestions?
Thanks in advance,
Ken

For your budget that is a good fit. You might want to pick up some tuning weights as well.

Looks like 90gtvert linked you to a Hoca clone. Which is a great variator for jog minarelli platforms. I'm pretty sure the only difference in material or performance between the Hoca an ssg is the name. So your good theređź‘Ť. I recommend picking up the variator face also. Wether it be Hoca or ssg. You don't Have to but these variators have a coating on them and it's probably better to run both at first. With my 93 Jog the Hoca variator gave me a feel of smooth constant acceleration all the way threw its gearing. 6-7 gram rollers.  |

I agree with every thing said so far on the variator brands and the weight change options.
the other part you might want to consider is, a rear pulley with straight cut grooves. it helps with the smooth straight "gear" change as apposed to the "high/ low" feeling shift of the stock curved groove pulleys..

I’ll definitely take all the advice into consideration. Was already looking into a variator drive face and rear pulley since one without the other two seems less than ideal. I’ll be sure to pickup some tuning weights as well. Will probably go with sliders in the long run though. I’ve heard to get .5 gram heavier sliders than whatever I’m running for rollers. Is that true to everyone’s experience here?
Anyone have a recommendation for a good rear pulley to compliment the hoca clone variator and drive face?

A koso variator has the same size of an over range variator at 99mm drive face,and can have a matching front pulley for cheap as well. This would increase topend and lowend when paired with a rear pulley.

This would increase topend and lowend when paired with a rear pulley. So, I was debating an over range setup... however, with a stock cylinder, is it really worth it? Is there enough power with minimal mods on a 49cc for the over range to be worth it? |

I dropped my 0-30 speed from 12 seconds down to rounded out 10 seconds with the rear pulley and belt alone. Even gotna video side by side comparison to show the difference and even gained topend (uses to be 39mph max,now im getting 46mph) on a completely stock 49cc scoot.

The best part about a trans like this.is when you put a pipe or a kit.and tune your trans you wont drop out of the scooters powerband.
Tested these rear pullies on a ported 70 and a completely stock engine to see if there is a benefit. And the better power delivery being smooth with no drop in rpm sure makes acceleration that much better.

Is this with an over range pulley? Just from the rear pulley and malossi belt on a stock front variator with a completely stock engine as well it dropped from 12 seconds to 10 from 0-30. Well 9.97 seconds. But ill round up. The front pulley is what helped me gain more topend. |

I'm more after a bit more top-end than anything I'd say. May be doing some short cruises on 55mph roads and would like a higher WOT speed.
