yes, a stock pipe and an economically ported trail/race head. I saw your new dyno graphs- it still needs at least a full turn richer on the needle. It's still leaner than the original runs and that's costing us some power.
Isn't it interesting how we're making MORE mid range AND MORE top end with a bigger carb and HR4-650 cams?? Turn that needle a turn and it will probably make more bottom end too!! Now throw an Ugly Stick on it and send it off the top of the graph! I thought that was a low reading dyno?
Disclaimer: not everybody can switch from HR3's to HR4's and pickup bottom end and mid range- it's the combination that works.
Nice.

No difference between graphs except torque has longer flat range at max torque on HR3. It takes a lot of comparison since torque and hp are not same quanity legend (i.e. hp and torque don't intersect at 5250). To me the HR3 looks favorable, and HR4 will only reduce torque further with higher peak drag racing hp.
Good Luck!

222,
you said that flat track tire give what 3-4 hp on a dyno? from knobbies. right? then if your off a jet or two that will take up say 2-3 hp ? right. ok so if i still had my bike i would be the same hp if not 1 more than flyinds. ON the same dyno. so if i would put on a drag pipe on his or my bike the dyno would go off the graph? well i dont think i did to bad for throwing some off the shelf cams and piston and carb AND MY OWN PORTED HEAD together to get what i did now did i.
plus iv only been to the dyno 2 or 3 times. so i dont get to try this and that every weekend.
sorry i just seen randall post " I THOUGHT THAT WAS A LOW READING DYNO?"
not trying to start anything.
by the way good #s flyin! it should run very good!

Randall, I don't think they're totally up on tuning the lectron. I was in talking to them yesterday they said that the needle was out of the tuneing equation when full throttle and it was just on the powerjet. Flyinds needs more tuning info to give them so they understand the lectrons circuits better, so he can get the most out of his setup, cause I'm coming loaded for Bear!! Well maybe ground squirrels anyway. LOL. Can't wait to seee the new build run Dave.

well got my ds on the dyno with hpr 4 cams, lectron 48hv and a little change in the exhaust. i gained 1 peak hp but it started to keep gain after that. pictures should be up soon.

Are you sure you are looking at the right graphs? I see just the opposite...
Thanks

I've heard from several people that this is a low reading dyno- not any one particular person.
Crazy- I understand their thinking on the needle, but it does matter when you hit the throttle- it will affect the power alot at first and then a little on top because it's hard for the power jet to recover from the hot/lean condition.
On a wide open throttle drag race, never letting off- it wouldn't matter at all, though.
