front sprocket

errrr dunno. Chains come with extra links anyway I think.

You can put an extra tooth on the g/box on a curvey SVS with the standard chain, there's just enough rear wheel travel.

Mine has a 16T instead of the std 15T, and it's like Dizzy says. Feels more relaxed on long distance work. I always used to try for 7th gear, never do now. I don't go in for traffic light grand prix starts so I'm not bothered about that. Fuel economy doesn't change noticeably, maybe a mpg or 2, that's more down to riding style.

You just have to get used to the new gear ratios, 16/44 makes 5th almost exactly half way between 5th and 6th with 15/44. As long as you use the correct gear there's little real world difference, real world isn't like race-tracks where you can optimise gearing for the circuit.

If you want more relaxed, go 16T, if you want wheelies go 14T.

I notice the difference particularly around 30 mph in second. On Suzy you get 30mph bob on 5k, but you'll be doing 4.5k for 30 mph on Dave. I have to keep an eye a little more on the speedo, as its tooooo easy to creep over the speed limit, I look down and i'll be nearly at 35 mph, and it isn't screaming to be changed. ( I like to keep my noise down you see)

I can't be forgetting, if I've been jumping between the two bikes a lot....not hard at the mo, only one bike working again

What chain? JT sprockets are good stuff.

Not worth swapping sprockets depending on use no way, swapping a front sprocket is a right PITA and there's only so many times you can re-use the lock washer before you're playing with fire.

I'm one up on the front and it's great! Brilliant for the motorway 80mph on the clock and it's just chugging away at 6000revs.
As for the corners I have not had any problems either still has the power there to put down on the exit.

You can order chains to whatever length you so desire.

I have a few questions about sprockets...

• Standard rear is 45 iirc? What's the top speed with an extra two or three teeth?
• Does the bike power wheelie with an extra two or three?
• Is the bike noticably quicker, a worth while mod?

I've got 3 (from naked) up on the back, I've had 130 indicated on the naked. Yes it makes it easier to pop up, especially in 2nd. I like it, but you're turning a lot of revs on the motorway.
