This 2nd attempt, don't know what I am doing, but type out long narrative, and delete it, what a pain?
So, next I installed the Malossi variator and went for long ride. I really like the Malossi variator, it made a huge difference. I thought maybe the oem variator would be good, but the Malossi works so much better, gives more revs at slower speeds, and higher top speed. Revs jumped to 9000 so a little too high, but scooter ran great.
Next I installed MaLossi green torque spring to drop the revs, and it dropped them down to 8000. Was pretty close to perfect. Could cruise at 8000 where I like with speedo on 50mph (approx 45mph actual). I have 8g sliders on the other scooter and plan to try them soon, just to see the effect. 8000revs probably still past peak torque/ HP so 8g stliders may be better.
Malossi torque driver a big plus IMO. The dog leg issue has completely gone away. It climbs hills great, goes against the wind great, it is great going up a hill into the wind. With the straight groove torque driver revs go to 8000 and just stay there until the CVT is in it's highest gear, then revs start to climb as you continue to gain speed. Depending on which way the wind is blowing/ elevation change revs can get close to 10000.
Don't know if it's really that helpful with BBK extra torque/ HP, but with 49cc engine it really increases performance. This thing is fast IMO. I can cruise on 50 to 55mph country roads (I pull to side and let faster cagers pass from time to time, but not a problem), in city traffic 40 to 45mph I am fast, a cager passing me is speeding. At stop lights and the light goes green it revs to 8000 and just stays there, sweet.
My final set-up: stock 49cc LC with Tecnigas Next-R pipe, pod air filter, oem Keihin 17mm carb 40 slow/ 108 main jets, CVT with Malossi variator, 7.5g Dr Pulley sliders, Malossi green torque spring, removed the Malossi yellow plastic torque controller (was concerned about coil binding with torque spring compressing too much), oem fly springs, and most important Malossi torque driver.
I ordered another one. I plan to set-up the other Super 9 LC the same, except will try the other set of straight grooves on the torque driver, see what difference it makes. The way this thing is running I don't feel the need for BBK, but we will see when I ever get the People 50 2T BBK running. Cheers
