Thanks for the advice Mike but the bike is doing exactly what I want it to do: pull like gangbusters in the lows and mids. It is much stronger and more responsive than stock. Besides, I have poured enough money into already for one year.

Also, the dyno operator made a comment that it was a strong running VTR (and they mod quite a few of them) so that is good enough for me. Besides, if I really wanted top end, I would buy a R1 (since Yamaha is my favourite brand anyhow)

cheers

 

I dont suppose anyone has a chart for a stock VTR for a comparo ?

HP only

 

Thanks for that... I love the warning at the top of page...
They probably have that there as a result of someone going bang

 

What do you call headers ?

Mikstr, Is it the power out of the wheel, the crank or the gearbox ?

 

Arent all the drive on dyno's at the wheel?

 

measurements were taken at the rear wheel

 

of course measurements are always made at the rear wheel but corrections are sometimes applied to calculate corresponding power at the crank or gearbox ...
So this dyno represents around 105 Hp at the wheel ? ( Then about 115 hp at the crank ? )
