It's to do with the angle of the chain. Might only be a few mm, but apparently it makes a difference.banoffee wrote:interesting. the one it replaced (i.e. was on the bike when I got it) was the same way round. will have a look, cheers.viper_biker wrote:Banoffee, that sprocket is on back-to-front. The step should be pointing towards the wheel, not away from it.

Re: smaller sprocket set
Definitely 14/44, cos I don't want to travel more than a ton anyway.
How hard can it be?

Re: smaller sprocket set
rode 14/43 for about 90miles and the accelleration was brilliant but high revs on open roads made me swap to 15/43.mick.mh2racing wrote:Definitely 14/44, cos I don't want to travel more than a ton anyway.

Re: smaller sprocket set
Can you buy chain and sprocket sets with -1 front tooth? if so where?
What number of teeth front and rear does an RVF400 NC35 have as standard?

Re: smaller sprocket set
Banoffee, Viper is right, the step should be facing the wheel. Looks like a Rentha HA sprocket like I have and the writing should always face out. Again Viper is correct and it may throw your chain alignment out slightly

Re: smaller sprocket set
VR6will - I always get my sprockets from B&C Express in Lincoln - always use Renthals personally. They are good value and very helpfull

B&C express seem to be a popular choice and are quite helpful: http://www.bandcexpress.co.uk" onclick="window.open(this.href);return false;
Give them a call and they'll tell you the correct number of chain links for the sprockets/bike you'll use.
A 520 pitch chain&sprox (lighter) is a good mod too!

Re: smaller sprocket set
Been using the search - the 14t appears to be a popular conversion, as does the 520 pitch conversion, and while I'm there changing the chain I might aswell do it.
I'll give bandcexpress a call in the morning!

Re: smaller sprocket set
-1 on the front.
Ive got a +2 on the back as well and its a bit too much if you want decent motorway cruising. I came back from a bike rally in france in 6th at over 13,000 revs for most of the time, just trying to stay with my mates. i felt very guilty about thrashing the engine that much for so long. That was on a NC23 though, not sure if the viffer engine would handle that sort of abuse.

Re: smaller sprocket set
whats the difference in changing just front sprocket compared to just the rear?
I.e. why would you leave the front standard and go up a tooth or two on the back? Or is that not the done thing?
