gearing

bubba · 02-08-2004, 11:37 AM

i took off the rear when for a change and have 2 extra gears lying around and was wondering what I am buying by switching from the 48 I have now to a 45 or a 42.

One VERY tall first gear and poopier acceleration . . .

45 is OEM, isn't it?

Make sure keep an eye on chain length too if you're changing that much!

Can't you drop a tooth on the countershaft sprocket? This would make the most difference without having to add any links.

i could, but i already had these gears lying around. how many would you drop

, i am at 15 now.

i am looking to have more responsiveness down low since i cant seem to keep it high ( i think it is the sound, i hear the high revs and shift instictively) especially since buying the twin

I would drop one tooth and keep the 48. Give this a try before you go any further, you are at 3.20 to 1 with 15/48, so 14/48 will bring you to 3.43 to 1. This is getting pretty low already, but that's misleading depending on where you are going to run the bike. Road Atlanta's back straight would seem to require something quite a bit higher (like 15/43 or so), but then I'm not certain where you are running these days . . .

i think road atlanta will be the exception to my track riding - as i can only seem to get on there 2 times per year with nesba. Probably more like Jennings, CMP, maybe VIR

You probably already know this but 15/43 is what came stock.

bubba · 02-09-2004, 8:09 AM

actually I had no idea. i bought the bike track prepped and never owned an F3 before.

actually for future reference the stock setup was 15/44

ccwilli3 · 02-12-2004, 10:14 AM

hmmm, things change over the years... the 600RR has 16/43 stock, just like the 929RR.

You sure it wan't 15/43?

redcliffs · 02-12-2004, 10:28 PM

the F2 is definitely 15/43, and I thought the F3 was the same...

BDA116 · 02-13-2004, 12:25 AM

The F3 stock is 15/43. The F3 responds very well with a 14 countershaft sprocket. I kept 43,45,46 and 48 tooth rears in my van. To be honest, I found the 14/46 combination very much to my liking at most tracks, and a good place to start when finding the optimal gearing.

yeah - i pulled up a site that listed all the stock features of every bike and when i chose the 97 F3 the gearing was 15/44

BDA116 · 02-13-2004, 10:22 AM

That is interesting. I know my '96 F3 was 15/43. I guess they changed it up for the '97-'98s.

Yeah, I had a '95 and it was 15/43. I even checked the fiche on Ron Ayers and it listed a 43 on the '97-'98 models.

i dont know bout that one ................my 98 is 15/43
and my best friends 96 is 15/43

showmethebombs · 02-22-2004, 6:49 PM

i had a 15/46 on my F3. It helped quite a bit down low for the 2nd gear wheelie. top speed dropped to about 135 from 145. (or so the speedo said...but I never went that fast...

...much)

(back in the day squid talk, please understand...things have changed...a little)
