The bike has a K&N filter, Motad venom s/steel downpipes and a Simmi Performance end can which I run with the baffle removed.
It is re jetted due to having a top end flat spot at 9000rpm+
The original flat spot happened after fitting the Venom downpipes.
It does run well, and pulls well through the rev range (usually) I've done various runs and checked the plugs they are a good colour when using 95RON.
I only put the V power in because I wanted to brim the tank with a fuel that doesn't have ethanol (I might be proved wrong and find out it does have ethanol) as I'm not using the bike a lot at present. I will go out if we have some good weather over the winter and top it up again. To be honest I wasn't expecting much if any performance gain by using V power.
So I rode about 5 miles before filling up and all was well, I filled up, rode out of the petrol station about 200 yards and had to stop at some lights and then the revs started to rise and fall, probably 200-300 rpm. When I went to set off it stalled. Same thing happened at the next set of lights 400 yards down the road.
I had been off on a bit of a bimble but decided to turn back home as it was running so badly. Route home was a 30mph zone which was OKish but if I wanted to pass anything and opened the throttle it bogged down. (Over 7000rpm all was great).
I asked my lad go out on it yesterday and he had the same experience, so he drained the tank and refilled it with 95RON and took it for a blast - all was good!
And he got a tank of V power for his Gixxer which only runs on V power (BP Ultimate etc.)
