Follow up on Cam install...
The install went awesome and taking my time, breaking for lunch and helping the wife clean up her yard sale it took me about 4 hours...
I used the Screaming Eagle Quickie pushrods, Screaming Eagle Hi output oil pump and cam plate, with the Vance and Hines 575 cams...
After install I uploaded the new map on the FP3 and went out riding...
I had a bit of sputtering on the low end so I decided to enter the autotune...
I ran auto tune 3 times applying each time afterwards (aprox an hour of riding each time.) I then finished auto tune and the bike ran GREAT...
on way home I had a couple of sputters rolling from 1st to 2nd so I called V&H Monday morning, uploaded them my latest map, they made some adjustments to the settings and sent me back a new map... Its been raining here so I have not had a chance to try the new map out yet.
Here are some of the photos and I will be uploading before and after video so you can hear the sound difference.
Nicely done. Sounds good. You going to have it dyno tuned? What does the butt dyno say?
Butt dyno says I am looking into tearing it back down... Not right...
Bike seems slow... think I might have an oil scavenging issue... Rode it and the oil level went down (classic scavenging issue)
Pesky oil pump o-ring possibly
I Definitely have not seen an improvement in power anywhere thus far and I think that something just isn't right... I expected to be able to tell a good bit of difference...
I assumed changing the cams would do a bit more than change the sound...
Anyone else's feedback?
Hope you get it worked out, you could run the bike a few minutes and cut the engine off before it Idles a bunch and pull the bottom drain plug from the bottom of the block and measure the oil, if it's 4 to 6 oz you shouldn't have a sumping issue, if it's more then yea, it's sumping. You will have to be very careful to not over tighten that plug on the bottom though, it's a pipe threads so it could crack the block if over tightened.
Personally if it's not sumping then it's tune, my friends at J&B Performance won't use the FP3 at all and there good tuners.
This dyno sheet shows a FP3 tune vs a dyno tune with a Power Vision tuner, they tried several different downloads from V&H's and even tried the auto tune feature also, well as you can see there's a huge difference in how the bike ran and the OP is beyond satisfied.

Guy that tuned mine won't use the FP3 either. Most tuners don't like them. Im sure it has taken some money away from them besides the fact that there is not substitute for a quality dyno tune
Suggestion
Use Grease to place the O-ring in the hole then put your oil pump together piece by piece assembling it inside... then put on your cam plate. Pesky O-ring failure
