Damn, dude. Get that 14 off just to save wear on the swingarm and chainguide. Go up on the rear sprocket.

We don't even know if you have a TLS or TLR they have different gearing as standard. Unless you have a speedo healer or some other recalibration device fitted, no ,atter what the gearing is the speedo will read the same for the same rpm in each gear.

i.e. If the speedo says you're doing 150 @ x RPM when you change the gearing it'll still show 150 @ x RPM. You're actual road speed will be different at x RPM, but you'll never know it by looking at the gauge.

Go here >> http://wotid.com/tls/content/view/12/39/ Click the TL gearing calcualtor spreadsheet and punch in some different sprocket ratios and see what the difference is. Hopefully you can do enough basic math to convert from kmh to mph if that's what you need.

Are you sure you're running 14/43? That's 3.07:1 standard is 17/38 for a TLS for 2.23:1 that's a difference of roughly 37% :eek

You know if the bike could do 160mph it can now only do 116mph :laugh Doesn't matter what your speedo says, that all she's got :crazy

Like tillerdog said, you have to know the different combos to know the difference. It is basic math.

17/38 = 2.235 X 1.374 = 3.0714 (3.0714 / 2.235 = 1.374)

14/43 = 3.0714 X 0.7277 = 2.235 (2.235 / 3.0714 = 0.7277)

160 X .72 = ~116mph

or your ~116mph X 1.374 = ~160mph

Hey steve tls, thanks for genuine reply! info helped staight away, we knew something was wrong, on limiter in every gear with arse end out thought maybe engine had too narrow a power band. its a R engine in a special with rolling road tested @ 131 BHP @ rear wheels. engine has had heads gas flowed and ported, compression raised, remapped, exhaust manifold and race cans fitted. thanks for reading and youre genuine help all the best tanker
