Brand new, never used, 12t. $65 shipped.

very lightly used Comet 2 speed assembly, along with Max Torque 2 speed clutch (3/4" crank) Both have the same amount of use, not much at all. Jackshaft is 8.5" long (take off from a Rupp C350 as we put it back to factory setup-non jackshaft/direct) Very clean, j/s support bearings even feel...

Picked up a engine with linkage coming out on the output shaft side, can anybody tell me what engines used this setup? I can't find much info on this. No shroud so I have no idea on size /age etc. . Thanks Ron

my all original 69 roadster started to slip when shifting from 1st to 2nd gear. i took it apart and installed a brand new Spag bearing and it worked perfect for about 3 months. Now it is slipping again. Can anyone guide me how to correct this once and for all?

Looking to do a Two speed jackshaft on my Trail Horse. Found the engine clutch but where can I find the clutch for the jackshaft. Is there anything special I need to know. Thanks.

Is there anyway to adjust the choke rpm speed? Mine starts with one pull, dead cold with choke on, however rpms are 3500. Is that what they are supposed to be?

Yeah I know I'm reaching for the moon here, but I have all the pieces to complete my Boonie jack shaft except the coil spring that locks the small sprocket. I would even be interested in a shaft in any condition that I might be able to repair with my parts or even rebuild.. any help would be...

I've been out of the loop for about 40 yrs. When I was a kid, we ran B&S, Tecumseh and Clinton engines on our mini bikes and fun karts. When I raced go karts, we ran what you youngsters now call "smokers"...McCulloch 93's and 101's. I see that my age is showing when I hear guys referring to the...

Here's something you don't see very often. The steering wheel says "Century Speed Kart Mark I". It's been stored in a barn at my parents house for atleast 25 years. I have it now and am in the process of getting it running again.

Will this 2 speed jackshaft #713845 UNIVERSAL COMET 2 SPEED CLUTCH KIT work with this clutch Max-Torque Dual Sprocket Clutch for Two Speed MiniBikes ? I'm hoping to pair these 2 together on my 1969 Rupp Sprint. It looks like the 2 speed sprockets are further apart than the sprockets on the...

Does anyone have a original 2 speed trans for a TT500 they would be willing to part with?

It has come to my attention you are bad mouthing a friend of mine and an upstanding member of this forum over a few dollars. Very few. Based on what was presented by means of communications between you two, it is my determination you have issues. To report someone to Paypal over a couple of...

Anybody know if the jack shaft on this kit can be swapped for a longer one? Thinking about converting my two Gilsons from single speed to 2 speed and I need 11 1/2" jack shaft length. thanks! #713845 UNIVERSAL COMET 2 SPEED CLUTCH KIT

I removed the non working 2 speed of my Boonie bike to find the spring has no bite. I had aquired a jackshaft with the same looking shifted thing, but now with them side by side the are laid out differantly and i wonder if rotation direction is an issue if I switch the part out?

am trying to figure out my best gear ratios to order new jackshaft gears and am a bit confused. my stats are as follows. 12t clutch - 20t input js - 8t output js - 30t rear gearplate. tire is 16` high. this puts me around 6.5 ratio as far as i comprehend but whats the top speed going to be>...

Just wondering if 42mph is the absolute fastest i can go with a TAV-30 and if i can do anything to help it gain more RPMs but i must first say i have the Yellow driven spring and i drilled a 4th hole and it helps a big noticeable amount on acceleration but i can still only go 42mph. Any...

Was there ever a variation on the small framed Lil Indian's with the 5hp briggs and a 2 speed? I only ever see the 600 (3hp 2 speed) or the 700 (5hp single speed) in the brochures and adds :shrug: half tempted to order the 5hp plate for mine to move it forward and stuff one in it!

looking for a set of comet speed limiting weights for the driver on a 30 series. used, new doesnt matter. thanks
