Efe turbo chain and sprockets

[Bigkenxx]

Just wondering what ratio of teeth on the front and rear sprocket people use on their turbo projects thank you.

I'm using stock bandit sprockets on my bandit motored ET Ken which is 15/45,hope this is of use.

^^ same here, I've always used standard sprocket gearing...for road use.^^

Standard at the mo on the 1216 oil boiler draw thru EFE ....

but I did run taller gearing on my last Air Cooled Draw thru....which worked well.....17 Front with Stock Busa Rear .....

17/45 on my EFE engined GSX1100E.

Thanks very much lads , the bloody rear sprocket on mine is like a bin lid it wheelies to aggressive it's time for a new chain so I will change the sprockets to a standard ratio thanks again everyone

Why fit N/A gearing when you have loads of turbo torque to pull taller gearing (bonus is nicer ride not having to stir the box constantly!)

I used 17/45 on my Kawazuki and have 17/40 on the 1460.

Well I'm going to try standard as a base to start with , sprockets aren't expensive so can play around with the gearing to suit my riding style.

I have higher gearing and like gixer1460 says it's a lot easier to ride no up and down the box, just leave it in top and use the boost, when it was draw through the front wheel would come up at 120 gently then back down on its own, always good fun when overtaking on the mountain at the TT.

Cheers SRR

Dont forget to make allowances for wheel size. I would guess on a turbo bike you would be running 17inch wheels with a 180 rear which means 17/45 gearing is close to 15/42 on the original wheels. Have a look at http://www.gearingcommander.com & play about with the sizes to see what changes.
