Wanna know what they think?
Go buy it then!!!!

Sounds like you are going through the same thought process as myself, need a twin but which one?gilson wrote:I've been thinking of changing my Firestorm for another V-twin. I was thinking SP1, SP2 if I have the cash or then, but then, something more modern and I'm leaning to a KTM SuperDuke....
Anyone had experience of one of these?
So really it's a lot of money to squeeze out those last few BHP... still cheaper than buying an SP1 though!If your bike has a standard exhaust or severely baffled end cans (eg Quill T3) attached to standard header pipes there is only a SMALL genuine BHP power gain despite the maker's claims both of Dynojet kits and the exhaust. However there will be an improvement in throttle response and fuel economy.
The standard UK bike is generally 102 bhp and if you fit a dynojet kit
and K&N filter with FREE FLOW exhaust cans (not road legal) you can expect 106bhp - 108bhp) The cost of supplying and installing the Dynojet kit and K&N filter is £235.00
If you wished to go further then the installation of Moriwaki ST1
camshafts into "gas flowed and ported" cylinder heads generally produces
116bhp - 118bhp PROVIDED that a FULL aftermarket exhaust is used (eg
Akropovic, Yoshimura etc, etc) the cost of this engine tune is £1485.00
PLUS the cost of the exhaust system selected. Used exhaust systems appear on Ebay on a regular basis.
