I am curious on the A/F for these runs. Scan 2 or 3 look good otherwise.

 

Thanks for posting the dyno results IDRIDR! I tried and tried, but couldn't figure out how to upload them once they were scanned.

 

Me too! Unfortunately, what you see posted is all the info I have on the runs. I believe the jetting is a tad on the rich side. There's a little bit of soot on the end of the muffler tip.

 

Thanks for the link! I wonder how much hp the porting mods add vs cams only.

 

How important is exhaust upgrade on the 351 kit? I've been curious. See for yourself. Here we have Bill Blue's results for the 351 with stock exhaust and carb, ZrexRich 351 with stock exhaust and carb (Run #2), and ZrexRich 351 piped with the FMF powerbomb and Q4, stock carb (Run #3). Since Bill's run was different bike/day/dyno etc it may not be the best comparison, but still interesting.

 

The sun finally came out so I snapped a couple pic's of the bike.

 

What does sp stand for?

 

I was told by the original owner it stood for "Skagit Powersports" which is the dealership he bought the bike at.
