Call the tuner that you are going to carry it To to tune.
Bet he will tell you to keep the cam you have and let him tune it.I believe you tune is way off.

 

This is a 128 built by the local dealership, for a guy living in NE. PV 1 license.
He asked if I could check it, so I did. Green run is as received, & I told him the tune may need work, as that combo should be better than 85 HP.so he left it with me. Blue run is tuned. He has a bit of clutch slip between 4-5K, which he says he can't feel on the street, and I advised him to put better springs in the clutch.

 

I'm thinking the same. Gonna get it tuned and go from there.

 

I agree. The charts really get people wound up, and make them think the engine literally starts to throw an anchor out on the highway.

My dyno chart with the RS468 is a perfect example.

One of my friends and I had identical builds, other than cams. We both got them tuned at Fuel Moto, and his 22XE chart shows that super flat curve with the numbers above mine at 3800.

We have ridden all over the country, racing on backroads, etc., and more than once he has proclaimed "that dyno lied!" LOL he thought he would walk away from me in the upper RPM range looking at those dramatic lines on the dyno chart

 

Each time you've contacted us we've requested logs, this will give us firsthand information on the state of tune; the same ECM data we're looking at when we're on the dyno. The PV4 is fully capable for tuning your application, the software has all of the same tuning parameters as the other Power Vision devices, it does not have on board auto tune however the same tuning strategy & corrections can be done in software with the logs and its actually a more powerful toolset. I'm certain we can get the bike well tuned with log data, its something we do here everyday and it also allows us to diagnose all sorts of anomalies and potential issues such as intake & exhaust leaks, improper cam timing, mixed up O2 sensors etc. We're more than happy to help you get it worked out, its just going to take a little time & effort. If you would like to get ahold of Lucas at lucas@fuelmotousa.com he can lay out step by step instructions and get you started. Hope to hear from you soon!

 

Bob mentioned only once in the emails about any kind of data logging. That was on 23 November email. The rest of the emails were about different cams, a cam pdf with several cam specs, doing compression test to confirm timing and such. Data logs were mentioned here by other posters, how/if the weather effects logs, and getting it dyno’ed, which was the direction I indicated I was going with. I can do logs, no problem. I will get ahold of Lucas for recommended methods.

 

I'm on the fence on cam selection but keep leaning back towards the RS468. Started of thinking SS465, then woods 22x, then SS475, then woods 22XE, then I stumbled onto Star 30/30. Really looking forward to FM's revised/updated cam compare this December to determine my post warranty/fall 2023 parts shopping spree!

 

I don't think you can go wrong with any of these! I will probably change things up this year, I need to talk to Jamie.

If I can keep my low end, stump pulling grunt by changing exhaust, I would love to try the Star. What I really hate to give up is the awesome dyno tune that Jamie performed. Rides to Wisconsin are few and far between

Man, don't wait for warranty to be happy!

 

Thank you for saying what I've been saying for awhile.
