First gear ?

[Neal]

I thought I would just ask , what are my options with first gear . My bike has a dry clutch gearbox with a long first gear . Are there other boxes with a shorter 1 st gear ?
Thanks

[peterbike]

Yes Neal,   the R gearbox cluster.   I run the R gearbox in my SP, it has first & second lower ratios.
It works for me and means I can run 15 countershaft 37 rear, easy.

Neal

you'll get used to it and the clutches are tough enough.

What final drive gearing are you using ?

If not I have a spare R gearbox

[ybk]

An RS has a dry clutch and the short first gear.

[Neal]

I am running a 14t front and a 42 rear , most probably may go up to a 43 but I can only be sure next time I ride the bike .

I may as you say get used to the longer 1st gear , if I don't adapt I will try another gearbox or parts to see how we go .

You will get used to bad starts Neal and besides its better fun coming from the back

Sorry to trainspot (I noticed this in the workshop manual the other day):

Gear	3XV1	3XV2	3XV6	3XV9
1	35/13=2.692	33/14=2.357	35/13=2.692	67/26=2.576
2	31/16=1.937	30/17=1.764	31/16=1.937	37/14=2.642(*)
3	32/21=1.523	25/17=1.470	32/21=1.523	32/21=1.523
4	24/19=1.263	24/19=1.263	24/19=1.263	24/19=1.263
5	25/22=1.136	25/22=1.136	25/22=1.136	25/22=1.136
6	24/23=1.043	24/23=1.043	24/23=1.043	24/23=1.043

(*) I think this might be a typo in the 3XV6-9 workshop manual.

So I think R, RS and (early?)SP boxes are different. The RS has two different cogs and the (early?)SP three.

I'll get me coat....

[Neal]

Thanks for the comparisons

[jools]

generally on Sp's its the 1st, 2nd & 3rd gears that are differently ( I haven't compared all models)

Neal - I run 16/39 so you won't want to try my first gear take offs 

Is your tuning still bog standard ??

[Neal]

Wow 16/39 ! Ok I should not complain .
The bike has all the race kit on it so not "standard" but I feel I could play with the heads a bit .

[jools]

Neal

you should be wheelying in every gear then on that ratio 

[Neal]

It does lift once I get going and it was giving a few tank slaps out of T1
