That's just about what we've been figuring for twenty or so years now. As it get's harder and harder to get any gains, the costs of the equipment to get the gains gets a little higher. I remember a Kawasaki 650 I had, it was a "75" and I put an RC giant killer kit in it which consisted of high compression and larger pistons ( knocked it out to about 735 CC) and it also came with high lift cams. I think the kit was about $350 back then and I had to have the cylinders bored which I think was about $30 a hole or something like that. It might have given me another 15 H.P. at best and it never did run overall as well as the stock setup did. I think I also put a K&N jet kit in it too. From then on it got more expensive but more sophisticated until I just decided to keep them stock and buy more stock power and be done with it.Let's just say over $100/hp.
Bone stock vs. current spec. Current spec is ported head, custom intake cam, Wiseco high comp pistons, throttle body mods, different airbox, Yosh exhaust, Dynojet PCV, and LOTS of tuning. Both of the runs shown were on 87 pump. When I put in VP MR12, it makes 92hp...
This idea of hp mods is calling to me.
Would like to do for the upcoming spring / summer.
Already have the suspension and handling sorted.
Penske rear shock and 1 inch fork cap extensions added since this picture was taken.
Closest contender in the stable is a 2015 KTM 690 Duke, with a 2016 coming this month.
hi sorry don't come into this side much,with livin in Germany,I'm in the German forum moreYou drop a dyno read-out like that on us, with virtually no info on how you got there? How about helping us all out with detailed info, and parts list.
Great job with the mods.
Thanks, I didn't realize that was a link.Details are listed under the dyno chart above, and if you follow the link in the first post you will see some step-by-step mods along the way.
