with my upgrades I'm figuring I should be approx mid to upper 120's @ rear wheel torque and horsepower   
will i need  to upgrade ? or will the stock clutch  handle  the increase power

thanks John

Cant speak for stock clutch, but when I upgraded, I went with the Rivera Pro and would recommend the same

Can't say for sure.  Would contact them and ask their recommendation for your application, then search online for the best price

well i called rivera  to day and they are telling i have to grind down approx 3/16 of the clutch rod ?
I'm unsure about that  ... so i  got some advice 
and looks like I'm going with this clutch set up   http://www.aim-tamachi.com/product.php?productid=150&cat=72&page=1

As a few of us have partially or completely stripped out the OEM basket/hub due to it's aluminum mating to the steel tranny splined shaft and have gone over to the Rivera system to resolve this problem. We are running in the 110 hp/tq area which is less than you are aiming for so this may be a consideration for you.

Yes you need to shorten the rod, but no big deal to do.

Check to make sure you won't have clearance issues between clutch and derby cover withe the set up you are going with.  Some on this forum have had to grind the inside of the derby cover as I recall.

Barnett offers a clutch kit in their Scorpion line for the hydraulic bikes that you don't have to grind the rod for.  The Barnett kits fits without the grinder.

I have ran the VP92 from Aim and been very pleased with it. Its a good option to a completely new clutch if yours is still in good shape.
Plan on using one on my 120R soon.

If I remember it was the lighter option. You could really feel the reduction in clutch pull at idle. But as RPMs rise it will it will start to stiffen up as the weights
do there thing. Redline shifts take a little extra effort. I ran it with great success on a two different 107" builds that were both making 105/115 with completely stock clutches other than the VP92. The 120R may need the heavier one. I would go with their recommendation, these guys are pretty sharp.

What about those Baker clutches? Anyone try one of those??

[Bigjim1661]

55k on a stock clutch with a barnett heavy spring...119hp 128tq. Rivera is the great too, but remember to use ATF in the primary as per Rivera's instructions!

You mention completely stripped out the OEM basket/hub due to it's aluminum mating to the steel tranny splined shaft because
Wont the aluminum basket hold up and is manadory to go with a $500 steel basket?
