124 vtwin cam help
need some help here... 2011 FLHX with 103. was built up in 2013 to a 107 Big Bore by Scott from Hillside in NY with 132TQ and 123 HP , compression approx 10.5:1 with 777 Cams. I am in Canada btw
2 months ago I had the 107 punched up to 124 with same head work from my 107 build. Has new S&S Crank with minimal run out. compressions approx 11.1-11.5. S&S Flat top pistons. new lifters and adjustable valve rods. Cams still 777 which made it a torque monster but i don't like the start sound of the bike. it sometimes has a bad turnover. Battery is brand new. it seems i need strong CCA at times.
The leak test for each cylinder is 5 and 6% and cylinder pressure measured 200 PSI for both.... I do not see any bad build here other then cam selection on my part to keep it since they were still in great condition.
Has stock TB and SE Heavy AC cone model.
My question is are the 650 cams my best choice ? The bike has stock compression release and in PV tuned..
Bike has V&H power duals and 4.5 V&H high output slip ons..
Any suggestions would be a great help to direction i should take. aim is to have 160/160 dyno numbers.. or little less..
I have attached my Dyno chart

Double post; not a good idea. You already have a reply to the post in the Twin Cam Motors section; best to delete this one and keep replies in one thread. BTW, I agree on the reply from Max.

Heads ported for a 107" won't support 160 out of a 124,for 160 your going to need heads flowing in the 330 area, which isn't going thru happen with even the best ported OEM heads.i use 110 cvo heads on our 124" builds witch flow in that area after porting
