Hi, its chain & sprocket replacement time. I have always used stock chains & sprockets, I have heard people mentioning putting a rear sprocket on with 2 teeth less. What effect does this have on the performance of the bike??

I wouldn't do it. The 600 is revvy but if you are not careful the vibe patch might be even more into your normal speed range. The gearing is also set to suit the engine valve timing. You probably wont save any fuel and you could spoil the bike.
But... If you dont like the higher gearing, simply swap back to a std sprocket on and its not cost much to try.
By the way. My Suzuki GT 750 has standard gearing but its way overgeared. At 70 the engine is doing about 4000rpm in top and its barely able to maintain progress. Drop to 4th and it comes up close to 5000 and the bike is transformed. The bike effectively has only 4 gears. When the chain wears out I'm deffo going for a larger rear sprocket.

I agree with Dave, top gear is optimised for the engine characteristics. But when I had the XJ600N, which has a larger rear sprocket than the S, I did find 1st gear ludicrously low.
For that reason I wondered about gearing it up significantly and treating it like a 5-gear bike with overdrive. However, I've passed it on now so can't try it out.
Only thing is, if you put a rear sprocket on that's very much smaller, you'll have to take links out of the chain, so it won't be too easy to change back to standard if you don't like the set-up.

I've added a 46 rear sprocket to my D6. It does make 1st gear more useable but I've not been out on it enough to see if it has improved the fuel economy.
You can buy the sprocket from WEMOTO (£20) and get a normal chain and sprocket set from thefastone for £60 (it was cheaper to do this than buy the sprockets and chain seperately). If you decide you don't like the 46 tooth one then just put the 48 tooth one on. I think its going to depend on your riding style.......

I didnt realise the 600 N had lower gearing.
I had the 600S and was happy with the gearing, but I'd not want it any lower. If you have the 600 N you might want to use the S gearing ratios.

Aye the N has lower gearing which makes it feel altogether more perky than it's uglier, faired sister.
Yes, first gear is madly short, but the rest of the box is much nicer with the lower gearing.

My 600S has -2 on the rear (I don't remember how many that is but it sounds right. 45??) I get great mpg out of it even for a Divvy. It's slow, but it's a D600 so what was expected. I find 6th gear useful on the m'way, eg 5000rpm is at 78mph. You won't make fast progress but if that's what you want just go down 2 or 3 gears or get a fireblade (which is what I just did). It's all about saving fuel these days, esp on a commuter bike. With clutch abuse it'll still lift the front. Just!
