How does gearing really affect the bike?
 

I have a problem where my bike is too highly geared for certain slower corners i.e. if I approach the corner in 2nd it's too high (the revs are too low) if I drop to 1st it's too low (the revs are too high). I am running 14/45 so what do I do:

a/ Change to 14/47 hoping that 2nd will now rev ok
b/ change to 15/45 hoping that 1st will rev ok
c/ Leave it and do something different in the corner

The corners in question are Rocket Out (Anglesey) and Luna Right hand entry (Three Sisters), the bike seems ok everywhere else on the circuits.

I found that I was losing time on people who entered Rocket Out in front of me, and Luna is very important as it drives you down into the straight then over the summit to Cowards where lots of time can be made up.

I have enough chain movement to go either way so that's not an issue. But my one other question is this:

- On a little v-twin (69bhp) if I go low geared 14/47 (stock is 15/39) will I loose grunt i.e. will the bike rev out before it gets to deliver max torque/bhp?

Rocket out (Is that the hairpin at the top of the hill?)

Can't remember off the top of my head what gearing I ran at anglesey

I check tonight when I get home.

Always got great drive out of there tho .. so much so I could spin the back up.:D

2nd gear

maybe think about adjusting your line .. you need to get the power on early and apex late.

Might also need to think about your corner entry speed

leave it in 2nd and go in faster ;)

LOL ..

:o

Just found some notes on my pooter .. 15/43 at anglesey

Bradders is right I'm afraid

That's what was in the back of my mind, dohhh. And as Alan says I think you're right. I was running 15/43 at Anglesey so I guess it's me not the bike as always. I there this Sunday for some testing so we'll see.

Thanks for the replies.

The 800 has stacks of tourque that's where it's strength is against the SV's

Don't be afraid to get it wide open while leaning .. loves it ;)

Might try and make the wirral round in July

That's probably what I am missing I am not opening it up hard enough early enough. I have a TD on the Coastal this Sunday and then Wirral rd 3 on 4th June so will try opening it leant over.

rocket out..is that the hairpin at the top of the hill?

that's the one

cant remembner the gearing I ran on my little wheezy 48hp DD bike, but top 2nd out out there, and 3rd thru the rest from there with 4th occasionally between the two rights before the left into the corkscrew..but not as quick as an 800
