i feel the same. my problem is though im 50% off road.... and 50% on road.

This is why i cant decide on a 14T sprocket :)

Going from 15:45 to 14:45 is only about a 7% difference in ratio. Therefore, if you just learn to ride 7% faster off-road, you won't need to change your gearing and compromise the bike for road use :D

Or, do the fuelling, filter and exhaust mods and you'll find the bike will pull from ~2000 rpm rather than ~3000rpm, which is the same as dropping your gearing by ~30% (which probably isn't even possible) and again, doesn't compromise the bike for road use.

+1 on that. I found that sorting the fuelling made the huge difference to tractability and flexibilty on and off road. That extra 1K rpm makes a really BIG difference.

To back up the last two comments - at 50% and 50% I would stay with the 15th. The first thing I did was fit the 14th because at the time most of the riding I was doing was off road and as I have said in the past it was a good and cheap idea at the time. I then fitted the kev mod, stage 2 and have recently gone back to the 15th as I plan to spend more time on long tarmac runs rather than off road and because of ware issues with the 14th.
Now I find that with more mileage on the engine, the standard 15th and the mods I can get the same performance down low off road without the 14th fitted. In my instance the off road issue was with low down grunt not power.
I can fully understand why anybody who does a lot of 'technical' off road stuff would wish to fit the 14th - but............if you are also doing a lot of tarmac miles consider putting more miles on the clock and doing the air and exhaust mods as a long term 'fix'. Yes a more expensive fix probably, but over the life of the bike ...well who knows?

i get what you guys are saying about if you sort the fueling it changes the bike just like changing the sprocket does...but...i cant "sort" the fueling as that means changing the zorst...which makes it louder...and i HATE loud zorsts....

......am i right in thinking my only other option is to cut the CAT out of the standard pipe? (i know this makes it a bit louder but not "single MTC loud")

I can understand that - I am always aware of noise when off road and would love a quieter one.

jimmysimpson 09-08-12 21:57

Mines quiet because I have not felt the need to change it. I'm happy with the way the bike performs and I like the 14 tooth sprocket. Each to their own I suppose.

You'll find the biggest gain comes from the air filter and fuelling mod, less so the exhaust, so you could fit a DNA filter, remove the snorkle, add a Kev mod and gain flexibility without noise. Such mods won't break the bank either!

In fact the two things you'll need are in the for sale section here

oh right...i think ive miss understood all this then as i thought you couldnt do the DNA filter, snorkel removal and a Kev mod WITHOUT changing to a free flowing exhaust?? hence me enquring about cutting the CAT out to make it free flowing???
