my first blast on my 1st 'proper' bike was brilliant... obviously a lot faster than my nsr.. but it was just a great feeling being on the road on a bigger, quicker and better sounding faster bike
I hope your test dont get cancelled but i wouldnt be suprised.. snow just started coming down here in Bedford and forecast for the whole week

Dyno print out on the way, I had it done by Moto Corse, he said that it could do with adjusting a little low down, but I'd have to fiddle with the screws as it was below 5K.
He told me to just take the washers out.

Cool - never seena restricted bike dyno graph before...
Looks lean at low revs to me - if I read it right and so would benefit from washers.
Mine looks like this (or used to as the exhausts are changed now)
No air/fuel on that but it was dead straight.... Nice smooth cuves.
It is interesting how the torque on yours just dies off..

You don't want to ride it, its shit.
What would I do then to go about sorting out the leanness low down.
How come yours doesn't have the 5K flat spot? The one on mine at 5K and 7K is really annoying when I'm trying to do a fast getaway, its like my old RS50 when that was playing up
Yours look really good, how much BHP do you think the exhausts will have added?

laws etc aside i think im gunna whip my restrictors out as soon as i am used to it or as soon as i find a nice exhaust system which means it would need a re-jet anyway, i dont like the thought of starving the v4 of power and making it run shitty.
top speed restricted bout 100/110
top speed unrestricted 130/135
either way if you get caught your gunna have no licence, so might aswell just have them out and ride carefully.
bike runs nicer and you havent got horrible flat spots.
thats my plan anyway
