Hi!
Have searched for a 14 cog front sprocket without any results. Have asked the biggest Yamaha dealers to small motorcycle shops and none have what I asked for to the XT I know OTR have those but I don�t order just a sprocket from them. Has the wrf 450 for example the same splines? Or another Yamaha model perhaps?

Well why didn't you ask the Captn?? I know where you can get one, they are �8.99 before vat and postage, and you can get one at B&C Express follow this link, http://www.bandcexpress.co.uk/cgi-bi...OAD&nav=Yamaha

Damn! Yes, I should have ask you first before I called every dealer nearby. I will never learn. Luckily I found a sprocket at last, right here in good old Sweden. So now I can calm down and start focus on better things in my life

What is the standard teeth on both sprockets...an did ye notice any different wi a 14 tooth front...I take it this is smaller than the standard...Mabozzar

Standard sprockets are: front 15 teeth / rear 45
By changing the front sprocked to a 14 teeth your bike will gain a quicker acceleration however the moment you mess up with sprockets your speedo will give unaccurate readings, hence you might want to be careful when going past a gatso. To compensate for that you could fit a speedo healer but it has to be calibrated by someone who has a rolling machine and instruments to measure it. Personally I wouldn't bother with it, too much hassle.

If you want to learn more of the effects that a change in sprockets will do to your bike try and experiment with the attached spreadsheet.

Right, very blond question from me... I'm contempating changing the gearing for better acceleration (I don't need to go any quicker than 100mph anyway, and I want proper 2nd gear power wheelies!).

Which is the best option - Smaller front sprocket, or larger rear?

What will this do to my speedo - will it show 30 if I'm doing 25 or the other way around (that's the blond bit!)?

on your head be it young skywalker, all I know the speedo reading will be affected, one way or another you could be doing 50 and the speedo might say 40 and then the gatzos will get ya!

did u check out the excel sheet with the various difference in speed and revs by changing sprockets? here it is attached

Thats a really useful spreadsheet - thanks Fran.

I put a 14 tooth front sprocket on my XT660X ages ago, and it smooths out snatchiness loads as the bike seems to be in the correct gear more often, Yamaha certainly got the final drive ratio too tall on this bike.
As for the speedo accuracy I thought it now over-reads rather than under-reads so 32mph indicated is 30 actual and 64mph was 60 actual speed.
But I could be wrong I can't remember how I worked it out now!

cheers, strat.

No problems, I hope it will help you making your mind about it.
