Hey Gang! Need a little advice on if an over range kit would be worth it for me.
Current build is a 2001 pre-bug, 70cc tops black trophy, 17.5 dellorto, boyesen reeds, leo vince tt, 13/44 gears, tops variator kit, 6.5g dr pulley rollers, polini speed 3 clutch and bell (adjustable spring tension), and 1500 rpm malossi contra spring on a 2008 Zuma torque driver.
I'm torn between the Malossi and the Stage 6, if I would even benefit from either. I love my taller gearing but would like my launch back and who doesn't want a little more top end speed?
Keep in mind this isn'ta crazy high horsepower build and it lives under 10k RPM.
Thanks in advance. I always value your opinions!

go for it
it adds a lower first gear and a higher top gear
you just have to grind the cases a little bit

Thanks! I've read both those threads. Very good information! At this point I think I just want to do the whole kit with matching parts. I'm wondering if both the Malossi and Stage 6 require the same amount of machining. And once this is done, is it reversible? Say I decide I can't live without an electric starter for some reason, can I put it back? |

the machining will be similar the oversize pulleys will rub the case in a few spots a Dremel or sand paper can help you just get enough room to handle the larger circumference .
They usually have spacers /shims with the kits so you can have them spin freely on the drive shafts .
yes you can put the electric start back on if you ditch the overrange .
I have done that myself so I could get one closer to stock when I sold it

It gives you a wider transmission range than stock. So you would definitely benefit from it. Especially running a gear up kit.

you have enough power
I ran a malossi overrange with a similar power set up sport pipe sport bbk and gears
I noticed more on take off by starting in a lower gear top end was only a little higher .
A higher power set up would add more top end because you push through the wall of wind better

Thanks Zino and aeroxbud for all the advice and help on this. I'll update the thread when I get it done.

I finally have a little bit of an update on this after the first torque driver had a bad bearing and personal issues that have taken WAY too much scooter time.
I currently have the red contra spring in the MHR over range kit that it came with. The yellow I was running previously felt like it was letting the belt slip a bit in this kit. Do these Malossi kevlar belts need to break in?
I have that paired up with 7 gram rollers. RPMs are holding a steady 8200 up hills and while things are shifting. This is a few hundred less than my previous setup but feels like it makes as much power. What do you think my target RPM should be?
As for results, it didn't gain anything on top speed. Launch might be a little better if I could get that belt to grab more.
It does have gearing forever though. Definitely runs out of power when everything finally gets shifted out on flat ground. On a good down hill run, it should fly!
Also, the torque driver has the 2 different pin grooves. I'm currently using the one that shifts faster. So I could go to the other one and gain some rpm's if I need to. RPM'S are steady though. No drop or anything weird. Opinions?

Your RPM seems spot on for a TT.
All belts need to wear in a bit for best performance. Expect it to get better as you use it.
You have the torque drive set at the most direct pattern. The dog leg pattern will lower the rpm after initial acceleration.

The dog leg pattern will lower the rpm after initial acceleration. Good to know about the RPM range. I've really always wondered about that since the engine doesn't really have a "hit" like some two strokes. This torque driver doesn't have a dog leg option. Just the more vertical one that I'm using and a longer, more gradual one. Both are straight. |

The TT makes it's power quite down low. While something like a Yasuni R doesn't have the low down power. But has more up top, making the transition more notable.
