first..... thanks to john for welcoming myself and everyone else to his home for a day of dynoing that was alot of fun and very informing.

food was great. it was awesome getting to meet everyone. dont want to use names cause i cant remember all of them between real names and screen names. LOL it was great meeting everyone though. it was awesome seeing NHRA's raptor on the rollers.

john.... thanks for letting take a spin on ottsix. no doubt..... that thing rips. thanks.... now i gotta upgrade. ouch. wallet is sore.

ran mine on extremetec atv dyno back in march. mt. gilead, ohio.
ran mine again on the venom dyno. like i said in my other thread, when i dynoed in march it was like 45 degrees. we left it lean after the FCI. just guessing that it was gonna richen up with some warm weather.

jeff at extremetec is a heck of a tuner. he guessed about spot on. the A/F was about a bullseye on venom's dyno.


not much new info. we made six runs. it is unbelievable how consistent each one was. it looks like one big fat line. all runs were within .3 hp of one another. super consistent.

johns dyno reads about dead on with extremetec's dyno. both dynojets. so john spoiled my plans of having a 60hp machine with his reported super high reading dyno. LOL 56 will have to do since his reads like most other dyno's. LOL all runs have same mods as in sig. only change was from a non program to a programable dyna tec cdi. used curve one so its basically the same.

i had printouts, so i had to photo them to post. didnt come out to clear, so i painted it a bit to help see the numbers better.

best run was 55.90 hp and 37.59tq. it has an awesome curve. i like how its over 50hp from 7000 rpm on.

again thanks john and everyone that attended.

I just want to say thanks for sharing Steve. Good job bolting it together and it is very nice to see an honest graph in RPM with nothing to hide.

I EDITED THIS I dont want it to be taken the wrong way !

Looks like it is in STD, nice. Nice power and I want to see you win some hillclimbs this year!

Take some photos of the hills for us. Id like to see how verticle they are. I would consider trying a hilclimb or two but a long time ago I flipped a Wolverine backwards trying to show off and I have never climbed much since. It just about took my left leg off. I havent been to any so I am really unsure of just how baddass the hills are that you run.

No negatives, but
Still yet another FCI pulling lean on top...hmm

thanks miller.

i'll get some pics of the hills. pics never help though. doesnt do much justice. the night hill at the local club isnt to steep. its a good hill though.

our day hill is alot steeper. stock length bikes climb it ok, but its a handful for them. you just cant pin it or its comin over.


the first weekend didnt go as planned. weather on saturday was awful. i never even unloaded the truck. hopefully next one is better and i'll snap some pics for sure.

about the runs......... yeah it probably could use a couple sizes larger on the main. it read that way on the previous runs as well. its a 168 now. i got a 175. i could toss it in there.

well after looking at it again I see it doesnt go past 14 much, my bad... still though it looks like it might climb higher if it didnt spike...
