Dr Squid points out that one tooth less on the front is roughly equivelent to 3 teeth up on the back.
So if you do both sprockets then you will get something roughly equivilent to a 50 tooth rear, which would give you alot more oomph, but could drastically affect your top speed (though probably won't bring it below 110mph or so)
I don't believe a 50 tooth rear is available, so changing both would be the way to go to get that much, though how necessary it is I'm dubious of.

I only took mine up to a 46 rear with a standard front, because I needed to be able to cruise at high speed without revving the hell out of the engine.

i ended up going for the front one in the end - as it was the cheaper option of the two - im going to try it with the front sprocket changed to see what its like - may eventually swop and replace origional on front and buy a bigger one for the back, but as ive bought the front sprocket now im going to put that into use - sounds like i will have to pay more attention to the ware and tear on the chain now

I think as i will probably only be doing up to say 5k miles ayear (summer toy) it should be ok - i will be looking into buying a stronger chain to cope with the strain

Like Carsick said, 14 front & 47 rear would give you manic acceleration, but cut into your top-end speed... It'd probable wheelie really easily all over the place too

You'd get a hike in fuel consumption too

i do actually want to get the bike to wheelie OFF THE POWER - so i went down the route of getting the R6 throttle tube and the sprocket, am i heading in the right direction???

It'll wheelie off the power as stock. First gear, 10-15mph, twist the throttle quickly and firmly and be ready with the back brake.
Don't blame me if it all goes wrong.

Usually by this time someone will have mentioned blowing up your engine, but nobody has so I suppose I will. SVs don't like logn wheelies, they get oil starvation at the bottom end and can seize the bearings, leading to, well, nothing good.

Chain life, well mines at 14,500 miles and is fine!

Keep it lubed guys

For the record, mine did 20k with alot of abuse and an occasionally empty scotty

Mines done over 20,000 miles and it's still good. Thats with a scottoiler, cleaned every so often, and having to work a reasonable amount on every ride.

I've got 18000 miles on my original (from new) chain and sprockets. I use PJ1 Blue Label chain lube, which I think stays on better than most. They are coming to the end of their life now, but I will nurse them (ie extra lubing) through till the spring. In my opinion, one month of winter riding equates to several months of summer riding as far as chain life is concerned. Anyway, I dont fancy changing them in this freezing weather
