dyno run of my bone stock XR650R

Excellent I've been planning on getting mine dyno'd soon, it'll be very interesting to see how mine compares to that but I've been very curious what the XR will put out. I used to have a SM630 that peaked at 41HP, but that's a long and sad story I Cant wait to see what you have to do to nearly double the HP Taking notes and watching eagerly

BTW, Disalvo hu? You know I've got to ask, any relation the Jason?

This was on a dynojet 150 and is rear wheel hp. Was thinking more like 58 to start with but it clearly can get better. Not related to Jason, everyone always asks. Motors going to be apart for a while. Lots of things to change. Going to try to take it to Pikes Peak in June and set a record with it.

Figured I'd be like everyone and ask Very interested to see where this build goes

Been researching and most other builders are not quite as extreme as my plan. We have been working with the RMZ450 and made 65hp with a big motor so the XR should be doable.

dont think you will find another xr like this one will post pics when completed your's looks very good mate

Wow what's the bore and stroke on it?

hi mate engine was built by mw racing for the british supermoto - this was the secound enigine he built and paul from www.650r.co.uk sold it to me he did have both engines if you look on his website under used bike it will tell you more about it
im just near finish build just waiting on some small
thanks
will post pics when completed and full spec
spent allot on this bike but some bits still to collect when i get over to california

Do you know if anyone around there has a fuel tank that's made for crf plastics? I think its a Monnier.

yes paul will have he has loads parts and some amazing xr 's in his collection if you go to www.xr650r.co.uk web site

Ok I have seen the site before but it didn't say the tanks were in stock. Thanks. I have already thrown the stock one away
