Dan make sure the bigger clutch will fit. With the original comet 780 there's not much room between the tub and mounting bolt. Also make sure the belt is compatible for your new drive clutch and your existing driven i.e. belt width and side angle.

I'm using the one you sent for the t20 it's 1 3/16" belt isn't it? I've heard good things about the 94c, it's narrower than the other if it's going to be tight, the Kohler looks narrower but taller than the original opposed twin, I derailed quite a bit from staying all original, but I couldn't pass on a biggish v twin.Originally Posted by dirtdobber

Yes on the 1-3/16.
It doesn't matter how narrow the engine is. The drive clutch must align with the driven clutch. The only way to create more space on the clutch side would be to move the transmission over, which would be a tremendous pain!the Kohler looks narrower
Yes I was thinking about it almost all night, moving the transmission would be a huge pain, I suppose if I had too I could do like on a max and heat and area and have some sort of jig maybe involving a scissor jack to push out on the tub and reform it just enough to clear. I worry I might end up having to run spacers on the wheels to have enough clearance, if I were to need to stretch it. On my max the CV tech clutch was much larger than 94c, the side towards the engine was wider which in turn I had to set the engine slightly to the right to line up, it was tight but had just enough room to work without much effort besides the motor mount plate to offset it slightly.

Hey Dan,
I remember seeing a post where someone did just that, heated the tub and pushed it out with a form.
I didn't want to do that and found the CV Tec driven clutch. I think they are the same one used on the buffalo truck.

I thought I had a pic with the motor and clutch in but no need to move trans, move engine over. You may need to modify the motor mount, but could be easier than poking a hole thru the tub by mistake.
At least you have options.
