u want to change ur gonna need to change your contra spring or clutch completely, if you cant get anything out of your rollers anymore u need to change how much the rear pulley timing, going with harder clutch springs can also help negate the lost in acceleration if u go too hard in contraspring
@GhettoWrench 18 сағат бұрын
@xeemis ok so I should to a heavier contra and then will I need to use heavier rollers with it? Or just the same?

How wide is the mounting bracket/ location for the an400 I’m looking at making and adapter bracket to put it in a icebear vision
@GhettoWrench 18 сағат бұрын
@removeableskull7446 it's a crazy pivoting dual axle type bracket on top. But I think you could not even use that since it just uses that to mount it to the frame. You could just use the mount on the motor itself. A hole with a big axle looking bolt going thru it. It is 7.25" wide. Then the lower mount would be what is the shock mount under the suzuki. Or not even use that lower mount and find a place to attach a shock on the CVT like a maddog does.

Yes. You are absolutely right. I have a 2024 Honda Ruckus that came with 7g rollers weight. The top speed is 43mph. I put 6g rollers on it and have better acceleration with the same top speed. Then I put 5.5g rollers on it and believe it or not 5.5g is the sweet spot. I love it. Later on I decided to put the Polini Variator on it and tried every rollers weight and Sliders and I don’t like it so I stick with the stock variator with 5.5g.

Hey man when do when installing my new gears, for some reason my new shaft doesn’t want to go into the bearing on the motor side. The side with the gears and shaft installs nicely into the cover side of the gears. Could to tell me what’s going wrong and what am I missing. Shaft doesn’t want to install into motor side bearings. Does it need to be pressed in also?

@ when I gave my gears to the shop, the pressed it for a fee. I brought it home, took a look at it and it looked a lil crooked. I figured by not that much. When I installed it. I spun the rear wheel and for some reason just on certain spots of the rotation, it stops and have a hard time to continue spinning. Took it out. Called the shop and they said that there isn’t anything they can do all they know is that they pressed it as they should. Sucks I think I lost out, I tried the use two large sockets on each end to mallet one side. No luck, I think next time I will make sure that that gear is pressed on there good before paying the shop.

You will need the longest one they make usually. I ran the stock single for a few rides until I got an after market one with no issues.

@rodolfogarces903 So I have done a 28mm PWK and Cam on two different stock 150s. Both results were great. The issue was the 115mm variator. The new engine made power to faster with the 115 variator. The older 150 went the same amount faster with cam and carb, but would not make enough power for the 115mm variator. It went slower with the 115 and faster with the stock 107mm variator. So there is a fine line there

I bought a completely new WM 139QMB 80cc engine and also a Naraku v.2 90cc head plus cylinder kit. At first I was able to install only the cylinder, but I couldn't install the head because the rocker arm didn't fit, about 1 cm to the valves, it was impossible to adjust. When I installed the 90cc cylinder and 72mm head, everything was great. Then I installed the Naraku 90cc head and everything disappeared!!! The scooter barely starts (like a train), accelerates weakly and almost doesn't accelerate and wants to stop. I left the same carburetor, but even when I installed a larger 24mm carburetor, nothing much changed! What should I do???

If we could build or find a better kick start mech. For the 139qmb then were in business. The stock kick start mechs on a 139qmb doesn't last long as the teety strip out fast.
