Looking for a racing variator
« on: April 27, 2018, 09:54:30 AM »
Hi guys,
I'm looking for a racing variator for my 150 gy6.
I'm preparing for a race, and will need it by around the 13th of may. I'd order from overseas, but shipping is going to be too long and expensive. I'm prepping it for the dirt cheap enduro, and unfortunately I've got limits according to the rulse, so can spend a max of 1000 more.
Can anyone point me in the right direction?

What are you hoping to achieve:

faster pull-away?
quicker acceleration?

What you could do is fit slightly lighter rollers to a standard variator, then fit 2 progressively stiffer clutch shoe springs.

That would work better for a drag-race.

For general rideability, you may want to leave your clutch springs standard.

A racing variator is going to set you back more than R1K and you don't have the time left to order one from overseas.

Thanks @StanTheScootMan,
You're actually the one who warned me ;p
I found a racing variator at cms for a pretty good price. Will get that on wednesday.
Would've brought it to you, unfortunately the bike is REALLY not roadworthy at the moment, so will likely get myself an impact wrench to do the fitting.
I got 14g sliders that I would've fitted with the now destroyed variator, but the racing one comes with its own, so I guess I'll have to find a new use for those. Would like to get a bit more acceleration out of the thing, specifically for drag races. Needless to say the main route is still pretty long, and its gotta survive that before I even start worrying about the drags & races, so I'll likely be leaving the clutch springs etc alone for now.
I might look into the cdi as well, if it fits in the budget, as delimiting should give me a bit more topend as well, especially considering the bigger carb etc.
For the next event I'll look into racing cams etc when the budget opens up again, or maybe look into sourcing a 170 and tune that up a bit, but thats next years worries.

No worries. You don't need an impact driver, just a home-made tool to hold the variator still, while you loosen / tighten the crank shaft nut.
If you look at the variator's outer half, you'll see two holes that are made exactly for that. Get a piece  of angle iron or flat bar, three M6 bolts, a drill and a hacksaw and Robert is your proverbial uncle:
