My DS650 dyno run had a max hp of 43.9 and torque at 38.6. That is with an Alba pipe, K&N filter, and stock carburetor with one larger main jet.

 

Hey Amtchad,
Was the 7hp gain a peak gain number of was most of that in the 2500-4000 rpm range. If that was peak gain around 7000-8000 rpm I think thats awesome.
Do you have a way of posting you dyno chart on line so others can look at the curve?

 

Majorcho,
Yes, peak horse power was made at about 8000 RPM ( I dont have the exacts with me , they are at work.) and I know for sure that at 9400 RPM it was still making 38 HP, which was what a stock one ran one this particular dyno. It has a way broad torque and HP curve. Im going to post it all as soon as I get some pics developed. Happy Roostin!
