I am dumping the Triumph Daytona/Speed Triple conversion because it is just way to bloody out there! I dont need 150Hp hyper bike at 50 y.o. and the missus hates being on the back as she is sitting up on a pedestal like a pox doctor clerk! (Sorry to the Yanks, an aussie saying) I am looking at Ivan jet kit, it has a Leo Vinci slip on already, down 3 teeth on the rear, gold valves on the front springs and a Fox or something on the rear. Did I miss anything for a good torquey sprinter that lifts the front wheel at will?

Well, if you want to loft the front wheel at Will (whatdya got against poor ol' Will?), you don't wanna drop 3T on the rear. 1st & 2nd gear lofting is easy with stock gearing, if you want more, perhaps going UP 3T in the rear (or drop 1T up front like you did on the Trumpet so you don't need to change out the chain for a longer one).
:btw: That's gotta be the biggest Speed Trip I've ever heard of, but only 150hp out of 995 litres seems VERY detuned... that's about what a .995L motor puts out, isn't it? :wink:

Sorry, thats my old gearing talk, I meant up 3 T on the rear to LOWER gearing.

Just go down one on the front.
Eayser to change over - and cheeper !

It may be a little bit cheaper up front, but that added wear on the chain and missing out on being able to get a light weight rear sprocket is not worth it. That alone makes a big difference.
I also don't think it's easier. Taking the front sprocket off is a PITA compared to just pulling the rear axle and bolting a new sprocket onto the rear wheel. Additionally this is the perfect time to grease the rear wheel bearing and inspect the cush-drive!!

Well, if it's not yet time for a new chain, dropping 1T up front is cheaper than +3 in the rear because you don't have to buy a chain.
Reading posts over the years of folks with 14T, 15T & 16T countershaft sprockets, I'd have to say chain life has more to do with how well the chain was taken care of than if it's +/- 1 from stock. Any difference in "same owner" is likely to be small, and most will be willing to sacrifice 1-2K miles of chain life (if it's even that much) for the gearing they want.
Manny, how much of an improvement did you get out of an aluminum sprocket over the same tooth count in steel? I can understand it for the racer or the bling factor, but can you really feel a difference on an everyday bike?

I honestly think so. If you ever have the chance to stand there and heft the OE sprocket and an aluminum one in each hand, it would blow your mind. The Aluminum rear weighs about the same as the little front sprocket!! Then consider that this is not just rotating mass (flywheel effect) but also unsprung weight.
I have no empirical evidence and even my seat of the pants feel is skewed because I changed gearing and modified the rear suspension linkage. However, the bling factory is great while not gaudy and the price is the same! One of the biggest issues I hear people ask about is wear on the sprocket and I put nearly 10K miles on mine with no obvious wear on the teeth. Certainly not more than with the OE steel unit.
So why not??
