Hey Lurker. Good to hear from you. I haven't seen you around in a while. How's the brake upgrade going? I love the new rear disk I am running. Very capable brakes now.I was looking through this thread again and I notice you talked about adjusting your spring on the cvt. Would you care to explain how you did that? I didn't even know that it had the ability to be adjusted. Thanks.
Yeah, you have the ability to adjust the stall speed of the Comet. It's really easy to do. It's on the rear pulley. You take the center nut off and remove the pulley. It will have a green spring on it. You will see three holes on the pulley numbered 1,2,3. Stock setting is 1. If you want the rear pulley to shift into a taller ratio sooner you put the spring in 1, and latter 2, or 3. I went right to 3 because I know this transmission is designed for Karts that have small wheels. There is a yellow spring that takes it up a notch to 4,5,6 that you can buy online at various places. The shifting is subtle. In the stock "1" hole if you have the rear wheel raised and gas it the front and rear pulley wlll contract and enlarge about the same time. Now for me with the spring in "3" the front pulley will contract and after it hits the end the rear will expand.
It works a little better for me. Another tip I can pass on is the belt that comes with the Comet isn't really that great. Mine stretches and started to get sloppy. I bought on Ebay another but this one is made of kevlar and can't stretch as much and it works much better. Only cost me about 5 or 6 dollars.
I did a search on Comet belts and found all the serial numbers of like belts that are compatible. My new belt is a PIX A-203589A Kevlar 3/4" x 27 3/8", which is for Comet. You will like it. I have almost 550 miles on the new engine and love it.
