yes arry,
should have got that , but with the fuel alterations and brake sticking on i thought it a bit cheeky to ask [ i had 4 runs he only charged for 1]
and a queue behind me,

my 604 with 41 hp on the same rolling road[for comparison]

Yep, thats what we had on stock 604's Throbs was the same with a Keihen Carb but smooth linear power. With a bit - a fair bit of tuning we can can get a lot more!

after returning from the dyno i realised the rear shock was way too hard [too much preload on the spring]
so i reduced it only to find the bike sitting too low,
while at the dyno shop i discussed this and the lad there showed me some adjustable top suspension mounts [they set up race bikes]
so i've made a start on my own,
isambard would be proud.

sometimes your front legs need to be stiff and the fur on your arse vertical.
