The tapered pinion is a better deal.
Dark horse should have told you that...

Will do Bob.

 

Hot happy at all with the effen results. 60.94 HP and 79.55 torque. I thought I would have a lot more than that with what went into this build! Needless to say I won't be using this shop again!

 

Well, I take this is WOT run, so its not really street representative. None the less, that E/F ratio is all over the place. Not coincidentally, its at best where the torque is best as well. But it starts pretty lean and ends up too rich, so there is definitely room for improvement.

On the other hand, 108 n/m (80 lbs/ft) isn't all that bad IMO. What you miss is revs, or high torque at higher revs (== high power).

 

Yea that tune don't look too good. With all you did to the motor I would have thought low 80's/hi 70's. Something ain't right... Sorry dude..

 

Yeah Bob! The builder! Thought it would have been a lot better.

 

Have you ever done a compression test? I would to give me an idea where it's at...

 

Agree on the tune, AFR's could be better, the 9.5-1 compression is getting flooded on the back end. Don't know what carb is on it but drop the big jet one, should make a difference.

Something else comes to mind is 9.5-1 is a good safe compression but 9.8 or 10-1 will make a EV27 come to life and just guessing but a .030 head gasket would of helped also if your at 9.5-1 now.

 

I haven't done one since the rebuild. I guess I need to Bob.

Bagger it's a CV. I believe it's running a 46 pilot, 195 main. I'd been contemplating going with a HSR-42, but the tuner that did the dyno run doesn't think it's worth the cost / benefit.

 

Mikuni is a little crisper and hits harder but it's a lot of money like the tuner said.

Next question, did the tuner feel it was acceptable to have WOT AFR's peek at 12.5 and fall off to 10.0? a carb is a prehistoric metering device but can still hold better numbers than this run, you have power left on the table. I've ran both a modded CV and Mikuni 45 on the same engine with a digital AFR reader and both could hold a consistent AFR during a WOT when dialed in.

Something else is a 16.0 on the throttle wack, that is in detonation area, need to get the bike to someone who is going to tune it using the good equipment unless this was just a numbers run, either way you have work to do addressing probable detonation area especially in Summer temps and the back end flood.
