Newbie here. FRONT sprocket Q

LotusSevenMan · Post by **LotusSevenMan** » Fri Sep 22, 2006 11:10 pm

Sorry if this has been done to death, but just catching up with this site.
Am about to buy a '99 'Storm and the guy has changed the front sprocket for one with one less tooth (OME supplied as well). I assume this is to help bottom end acceleration. Now, that means the chain appears to be nearing the end of its adjustment as it is less distance around etc etc. Most on this site seem to favour going 1 tooth UP on the rear sprocket which would have a similar gearing effect but make the chain appear 'shorter' so creating the appearance of it being newer.
The real

is................. which is the best option bearing in mind I'll have the smaller front sprocket version already done etc.
Thanks in advance.

All right we can hear you!!!

One down on the front and Two up on the rear

That should sort your chain problem out but you might want to tie a breeze block onto the front forks to keep the nose down the first time you give it some beans

I've done 1 down on the front (15 tooth) and 2 up on the rear (43 tooth)

Runs very nice and would not want any more.

Nice and hard wearing and good prices too

Ah yes, I assumed with all the squashed flies-in-the-eyes and squinting through fly splattered visors you lot couldn't see the text! Sorry

OK, so I need to get a two tooth larger rear. Thanks for the info.

Remember that your speedo will now over read by a huge amount.

Factory built in error of 5-6% will be compounded by gearing change of around 8-10% (guess) meaning you will be doing about 85-90 when it says 100 (ish!)

Kingster
15/42 + "speedo healer" set to +12% to compensate

Kingster , this speedo healer,is it a plug in ,where do you get them from?
got a 15 t front,but i'm thinking of going up 2 on the rear,not too bothered about the descrepancy at the top end (rather watch where i'm going!)but in the limits it might be helpful.
cheers
