CVT Anyone Using A Comet Torq-A-Verter?

Comet TAV2 converter. Sounds like a lot, but Ive used at least 20 of them in the past. Smooth and quiet. Nice engagement. Quick.

graucho, which gears and pulley should I use?

Hey 5-7

Here is the link where I bought everyone of them. They give a great explanation twards the middle of the page how the drive and overdrive works.

Ive always order the stock tav2 30 series with the 3/4" bore 10 tooth sprocket. for the #41 chain.
My bikes always weighed between 140 to 185 lbs and they had great get up and go.
I fluxuated between 44 to 72 tooth rear, but I think 60 tooth (like Gungatim stated) you should be able to run at 40mph strong.

I also used the GP-730A Lubricant they sell and it works super! (also explained at the bottom of their page)

Hope this helps. graucho

I am running the TAV2 torque converter using #35 chain to a 60 tooth rear drive sprocket on a pusher trailer. The drive wheel is from a Honda Z50 mini bike. This also gives me the option of additional braking power. The sprocket was a fairly easy swap with the Honda wheel. I bought the sprocket which had the right center hole from an Ebay seller, then just drilled the bolt holes and away i went. Gives me a nice cruising speed of around 20mph and a top speed of around 25. I am using a small briggs type lawn edger motor for power. An easy way to check your wheel size with the sprockets needed to achieve the right cruising speed is located at www.diygokarts.com. The speed calculator has saved me many hours of trial and error.

Does your TAV2 ride smoother than a go kart clutch would?

I may consider making a trailer for hauling my stuff, and I want a smooth and not so shaky takeoff, so my stuff doesn't get damaged or fall off.
 
The comet 340 might be the best 'fit' for our application. The engine rpm 'adjustment' range is higher on the 340 than with the others.

According to an email that I received from one of the engineers at comet, with new belts, they transfer between 90 and 95% of the power to the driven pulley. As the belt wears, the efficiency drops, so, keeping them dust free & clean should help.
 
wow thanks graucho, buck and Lou for sticking with this thread and providing the great links.

i have a question though.

in the comet lit. that Lou linked is the statement........

"2.5:1 at engagement up to .8:1
overall ratio 3.16:1"

at which end ( low or high speed ) is this 3.16:1 overall achieved and how is it explained.

if it's at the high speed end then there must be some known value of internal reduction involved that would mean that the full overall low speed ratio is more on the order of 6.32:1 at engagement.

can you help me understand this ?

thanks,
steve
 
who has a picture of the back ( output shaft side ) of a comet ?

i'd like to see both engine and output shafts if possible.

thanks,
steve
