| The earliest that the bike will be on a dyno is November, its off to Sigma Performance this Autumn for a "Full Monty" and hopefully the magic they work will optimise the effect of the new pipes without major tuning, as has been suggested to you as being essential.
The thing is that the 57's are a good starting point. They allow the gases to exit asap and maximise the effect of any further tuning work at the business end.
As I understand it the fundemental tuning rule with twins is - big air in and big air out.
It will be interesting to see how much of a difference setting up clearances, settings and fueling acurately will make before spending money on new parts.
If anyone has any feedback on Sigma's work I would be interested to hear what you have to say. |
