rollers

[blue]

just put 3 -5.5 and 3- 6 in my scoot . runs good going up hills at 35 to 40 but takes longer to get my top end speed back on flats ground I had 6 in at frist should I go back to all 6 or try 3 -5 and 3 5.5
or all 6 5.5 I like the climping up hills at 35 or better but also like my top end better . what do you thing I should do. thanks.

Try all 6 5.5 rollers.

...5.5s work well with the stock airbox...

ill give it a try thanks

..my 4.7 Leos are pretty much shot..

..just swapped them out for some slightly better 4.5s....

A question for ya wordslinger. When dialing in you variator, why use different weights, if for example you put in 3 6 gram weights and 3 5.5 gram weights, what are the 5.5 ones going to do. Only the 6 gram ones will be effectively operating the variator, all i can see the 5.5s doing is adding to the flywheel effect. Am I looking at this wrong?

[wordslinger]

....the 5.5's will tend to sling out with less effort from the engine...

..tape a dime to the end of a 2 ft string...then try to sling it in a circle...

..now remove the dime, and tape a quarter...again, sling it in a circle...

..it takes less effort to sling the dime, right??..

..and..different flywheel weight WILL have a similar effect!!..

[sidthesloth]

but you will have 18 grams pushing the variator out and 16.5 grams just spinning, not really doing any work.

[wordslinger]

..but they will do work!!

..sssso...what if you take either the 5.5s, or the 6s out..and then pop in some 3 grams in their place....

..reckon that might make a difference?...

..it's still relative weight...

..ttrue, one set will work harder..but the weight difference is the key...

[sidthesloth]

Yeah, I see your point, but I'm still not entirely convinced. Must be that nightshift thing.

[wordslinger]

..but that just explains how a variator tuning kit works..i gota cpl of them...

..you can dial in your optimum roller weight, then get you some rollers in THAT total weight, divided by 6...

..it works...

..for my scoot, 4.5s gives awesome take-off and decent accelleration through mid range...

..4.7s give decent take-off and great acceleration through mid...

..5 grams gives a bearable take-off..decent mid range, but has more torque when running flat out...

..it's all about where you want it the most...

..top speeds are the same for all three......

[sidthesloth]

I havent tried that, I have just used roller sets. Might give it a try when I get a chance.

[wordslinger]

..it's kinda like fine-tuning what your engine / clutch is most comfortable at....

..you can do it best if you know what your actual rpms are at your set-ups best powerband..

..but you can tune by ear as well...

[sidthesloth]

Yeah, far better with a tacho, I am going to have to go to a smaller jet, now with the 2000 springs she is hitting a splutter right at engagement. I was able to ride around it before. Weather is getting cooler, does that sound right?

[wordslinger]

..i would think that with cooler, more dense air, you would need to go larger with your jet..

..to equal out the fuel / air ratio..
