Ok my bike is a 20 Fatboy, all cams tried with same build status 114 to 128 jim -max-cell custom matched/coated pistons,FM A heads 11.3 comp,SE64mmtb ported ward manifold,Thrashin 2-1 small dog ball baffle, comp ramp upgrade 2 tho run out cam side
other notes= i'm in UK, 1st cam done on super flow dyno (Dynojet convert numbers in that program),Techno research tune, other cams same Dynojet 250i dyno winpep8, PV, usual variables & skill of tuner guys maybe factors
Cam 1- Max-Cell 837B
Persuaded to go with this by a US friend, always seed to do the numbers
Received bike post build /tune numbers 156/154 =yep big numbers for a 128, fired bike up got that aggressive banging style cadence, on riding not clean lowdown need to clutch it, very sensitive on throttle wants to go, open it up pulls really hard but..... terrible vibes thro whole bike bars/seat/pegs not enjoyable, at idle can hear light comp knock , a drag cam ?
Thoughts cannot believe it,s coming out on my mechanical sympathy alone, gas milage range on refills 155/160 brim it.
Cam 2- Wood WM408
Obvious choice for my build with FM A heads
Relief ride ability back feels strong idles smoother,149/149 on 250i dyno still good numbers for a 128 pulls hard with out all the vibes still feel some as big cam ?, just around 30mph light clutching needed, lot of 20/30 speed limits here, got a bit tiresome ,maybe its the tune but thats what he could do? gas miles a small improvement.
Cam 3- SE517
Yes give this a try got a new one cheap ( cos everyone tosses them) dynoed by same guy as cam 2
144/145 surprised thought i'd do less , idles like cam 2 , but wow smooth off the clutch can cruise in 1 gear more at speed limits smoother than a stock 114, open it up pulls harder 3k up but it that smooth no vibes thro bike all rev range ,throttle back to cruise 60 in 6th cadillac stroll/smooth (my words lol) hard to believe same bike from cam 1, yeah i love it now
other shock was @ gas fill 200 mile range, ride ability now makes up for any reduced numbers on a chart
conclusion - well i;ve payed to learn what i like, maybe some cams tune easy others will not, i can post my charts 90% will pick Cam 1
Got a FXDR 114 done stg2 CR485 chose that cam because of comments of how smooth it runs compared to others they tuned, & yes it.s great just on a map not been to dyno yet for a finesse .
Interesting and I agree, everyone would probably pick the 837 just on numbers alone. Ever figure out what all the noise and vibrations were caused by? Wondering if others had same issue, or maybe something off on cam grind?

One other guy on here, stated he had the same problem with 837B ,claimed he sorted it -never said how
Bought this used 2020 STREET GLIDE 11,000 miles from the dealer with a 131 stage 4 screaming eagle putting out 129HP with 130 Torque on their dyno.Called Fuel Moto for a different cam and exhaust and decided on a RTX stainless steel 2/1 and a Woods 77x cam had it put on the dyno and got these numbers 140hp and 142 torque .

realizing this is just a dyno sheet forum, but curious what your overall review is ..how much did pipe, cam, different tuner? and dyno cost to get another 10 / 10 ish power increase? are you happy with the overall performance results, value, sound, any regrets? I can't imagine 130 / 130 before the changes was poor performance, thanks
Hey MJ ,Got $320 cam $350 tuner $1000 pipe free dyno benefits of club brothers.Night and day difference pull power imo is the best thing of it.Reason for change was wanted to get the most I could out of the 131 and I knew the cam and SE tune was the Achilles heel of the engine..Could have kept the same exhaust stainless header with S&S slip ones but I like the looks of the 2/1 stainless couldn’t say if that added or not HP so mostly cosmetic there.Overall I love it well worth it to me..Old scooter tramp like me has to some vices and my salmon boat and bikes are it.Oh Oh and good 12 year old single Malt Scotch whiskey 🥃 that helps.
