Thanks Matt
Yes I have tuned a few Kr1 's & KR!S's in my time, I enjoy tuning these little beasty's as they are a good tuneable engine as you can make them go well without the expence of expensive kit parts like rgvs or nsr's I would say that they are the last of the afordable to make go faster 250's we will ever see, I can't say how much extra power I can extract out of the kr1's as I have never had one on a dyno but all the engins that I have done for racing always led the pack when up against other kr1s's and always finished in the top 3 up against kitted rgv's
I remember back in 95 was at darly moor waching one of the KR1s's that i had tuned for a lad that worked at the motor cycle center in Stockport when I noticed a novice on a kr1 getting laped and been in the way of everyone on the track (bless him ) so after the race I went to see him & have a word to help him out if he needed. a couple of days later he rang me to ask when can he drop his bike off for a tune & set of pipes, we arranged a date I got him sorted I went to see his next well stone the crows

he was at the back of the grid the flag droped all I remember seeing was his front wheel go strait up in the air and he shot of the line like a scolded cat he had carved his way through most of the pack into the first twisty bend I couldn't belive it as he was never going to make a great racer (and that wasn't been awfull towards the lad any one who races will know where I am coming from , some have it n some don't) at the end of the race he ended up 2nd last but the thing was he was so happy cos he never got laped he beat another bike and his lap times had plumeted from the last time he raced at the same track before the tune, His results stayed the same all day he was a very happy bunny that day He did admit that the bike scared the sh"t out of him when the flag droped

now that to me was a result
Cheers
Mick
