Those springs are supposed to hold you down on the scoot seat. They are required for all the speed increase from the variator. You hook one spring securely on each side of the seat and one in front, then you run para cord over your legs and tie it tight. The instructions should have pointed this out in big bold letters.

I have extra roller weights that came with my big bore kit

correct..And if you have access to other rollers I'd use them, the provided one's flat spot quickly they seem to be more of a trial n error tunning roller. I've had the dlh variators before and they work ok for a short while in a stock motor but when I hit 72cc's I sheared the little guide pins off instantly

You need 6 of them all the same weight, or 3 of one weight and 3 of another weight(mixing). If you mix different weights, you need to alternate them.(see previous post pic)

Well if you all are familiar with me I have 6 of the same from a big bore install . I never installed rollers so I will use those

Mixing vs all the same weight rollers....we all know the total weight of the rollers is what affects your rpms BUT does mixing allow you to alter the "shifting" effect of our gear I guess you'd say? For instance if I'm running all 5g rollers and then switch to a mix of 4 and 6g rollers is my acceleration and top speed going to act more like 6g then while maintaining the rpm's of 5g's? Sorry floyd I'm not trying to hijack your thread, just seemed like a good place to ask while we're on the subject. We may all gain a new perspective or learn something new

Sorry floyd I'm not trying to hijack your thread, just seemed like a good place to ask while we're on the subject. We may all gain a new perspective or learn something new I know a lot of guys have mixed weights for a long time but to me...would it not be true that mechanically, it is still the heavier weights "trying" to do all/most of the work? Would that not put excessive wear on those heavier weights? I mean, I know the lighter weights will still contribute something to the demand put on them...but not as much as the heavier ones....right? I even bought a digital scale so I can make all of my sliders weigh exactly the same in order to distribute the load equally among them....in theory anyway. Bill My apologies to Floyd for the hijacking of his topic a bit.

That's kinda my thoughts too pirate. The heavier weight move out down the ramps at a different speed or rpm, bearing more weight/pressure on them. I think (I think) i could see where the quicker rolling weight would be the one controlling your "shift" variation. I'm happy running 4g rollers at 24g total but wonder if mixing to get the 24g would give more mid speed acceleration. What weight are your rollers floyd? Also is this the jonway with the hug flight brand kit,if so how's the kit? Seem to be quality parts and how's the head? Know some come with nasty heads

Each roller will provide a force proportional to it's weight. None of them will move faster or slower than others. They will all move in sync. They are all constrained by the variator ramps. Mixing roller weight is OK. The should be distributed to balance the force.
The guide pins and bushings are a big source of failure.

Those guide pins must be able too take the full engine torque. The bushings seem to crumble first then it is metal to metal for a quick failure. IMHO the variator design is crap.

IMHO the variator design is crap. it's crazy I've tried various aftermarket variators and they are crap and the stock tao tao was likewise but I have a stock 2004 kymco 2t vari and it looks brand new. No wear on guides or bushing and i know it the original , it's got time and date of mfg stamped on it. Just goes to show the differences in metallurgy and quality control.

I used the springs that came with my dlh variator and I'd recommend giving them a try Floyd (if u still have stock clutch) they will engage the clutch closer to max rpm and with that variator it will stay steady. Mine sounds exactly the same soon as you crack the throttle as it does at 50mph. I use the red 2ks now plus drilled clutch tho. The initial performance of the dlh will impress u but sadly you'll spend many a many day trying to replicate it down the road. Try 4g rollers
