when dropping to a #9 plug make no other changes to compensate for this?? he told me with his head work I would be right their in the 60horsepower range!! when bike was last dynoed at kenz, thought I would never have to rember that clusterf**uck!! they had a 110jet, today kelly went through some jets I had i have a #60 now!! Once again I always appreciate your help Jed!

 

Who did your head? And what was done?

As for the heat range, you might need to recheck your jetting. The 10's are a good plug, just dont burn off very well, and without a 0 2 sensor, its hard to read them. Most people keep leaning them out, to try and get the color good, but the plug is so cold, it keeps showing rich. Atleast that was my experience.

 

Jed I have had no headwork stock head!! thats why he iss telling me with his headwork with 1mm larger valves and if I had slicks my numbers would be right their around the 60horsepower range!!

 

Ah, I see.

But.......is the 730 he mentioned with his head or a Hpr Head? Wasnt it 61hp?

 

it was HPR head, and yes it was 61maxhorsepower I saw quite a few of his dyno sheets on ds650s, all the way up to the 800 turbo nitrious in the works!!! You know I am a believer of Hpr products, in my case of already having this full exhaust system and spending the extra 200 bucks and having 2 diffrent set ups, could not go wrong! One day I will by a Hpr ugly stick, but could not see spending the extra 300 right now for that set up!! will use that for the head work, nos,mods!! I told you this is going to be a competitor in stock bore!!lol and very seroius on the same note

 

Yep, that buggers going to run, thats for sure.

Let us know what you think about it once you get it on the sand!

 

hey jed your head work was done by who?? and from your experience what have you seen in the the head work, he says 5 to six 6 horsepower gain with 1mm bigger valves?? i do see where I missed typed the 730 was at 49max torque not 46max torque, 61max horsepower!! dont want to rob that owners numbers big difference, appoligize! In looking at the dyno numbers of different builds was weird how different bikes same set ups way different curves in hp and torque. along with peak numbers!!

 

Thanks for the replies I will call Kelly tomorrow.

 

dyno numbers were posted all weekend!!!

 

Where at?
