Gday All

Thinking of getting new cams for the bike, i was looking at the SE204's but my local dealer has suggested the SE254e of the SE259e . Not sure which way to go Bike has stage 1 done and nothing else, not sure if i will do anything after the cams but you can never say never.

I just want to have a little more oomph.

If your chasing hp from bolt in cams
I got over 100 with s&s 570 cams and same exhaust in my 2012 Fatboy
I think they might be cheaper than se cams

wonder why they are pushing the 259e cams, looking at the chart the 204's look like they have the best spread of gains? what am I missing?

yeah want to keep the warranty even though id love to give it a try my self. Doesn't look too difficult just need an internal bearing puller and bolt cutters, oh and a map that will work with the SE tuner. I have all the cables and I know that it all hooks up just haven't done anything with the tuner yet as it was mentioned when I purchased the cables that it could effect the warranty. What other cams were you thinking Hilly?

40thtoy. I'm in the same boat. Two years left of warranty and to guarantee my warranty the dealer will be installing se cams, adj pushrods, bearings and lifters. Probably a se clutch spring too. For me 204 is the only option. 1.725 ratio rocker arms (for intake only) will increase the lift a bit. My might go in as early as this week. If going to this effort and cost may as well have it dyno tuned properly

For what it's worth. I fitted S&S 583 easy start cams in my Fatty Lo, at about 85000km.
Great cam and really gave it oomph !! Lol

Think they are comparable to the 204s with opening and close times. Can't remember but there was a comparison I had seen somewhere.

As Hilly said, don't go over board .... No point running up a steep embankment too high , ya might get there but you'll be Fukd afterwards lol.

I've got 583's on the Fat Bob, bewdiful.

Good ta see ya back Hilly.

I have some Zipper Red Shift 527 bolt in cams. They have never been in a bike and the cams are still wrapped in the news paper and box they came in from America. From what I have read about them they are a very nice cam. Didnt get to use them as I went what is termed a stage 4, so a different choice of cam was made. Have them for sale if you are interested

I went with the SE204's and a dyno tune in my Dyna. I was looking at the SE255's because I like the low down torque but the dealer recommended the 204's as a better option. Their reasoning was the 255's ran out of puff a bit too early with a lighter Dyna. I already had a stage 1 kit and it has woken it right up. Mid range torque is a lot better, from 2,500 to 4,000 it pulls hard now. It gets a bit of a cranky cam lope down low when you are just tootling along in traffic, but it doesn't jump and buck around like some of the bigger cam options. Straight off the mark acceleration I don't really notice it that much, it is a lot better but not a massive quantum leap, but overtaking and roll on pickup is where it is a standout. I ride a lot with my son who has a cammed 88ci Softie which goes really well. When he was leading and would move out to overtake somebody I'd wait till he got halfway around then follow. We would be pretty well neck and neck and keep nearly the same distance apart. Now if I do that and roll it right on I have to back off and actually brake so I don't run up his clacker! Overtaking is a breeze now. Before I'd often drop back a gear, not now, I just roll on and slip around pretty quickly. It has also changed the exhaust note, it is a lot deeper now and sounds pretty darn good I reckon. I think you'd be happy with the 204's, they are a good all round cam choice with good mid range torque and don't fuck your warranty.

I got se204 cams fitted to my 103 and tuned earlier this week. 

 

 

FatBat was that a ful custom tune?

My apologies for the spelling

Torque drops off early

different correction factors..The guy using DIN has almost certainly got a buggered weather station in his dyno. One never sees a 1.06 CF with 32% humidity.

I picked the bike up thur, dropped it home and went to Melb for 5 days. So no time to see how the bike goes yet. The torque curve does look unusually skewed to the left. I'll speak to the tuner today. If it was the exhaust causing this i thought it would do similar to hp graph but the hp line increases steadily all the way to redline. Exhaust is a freedom performance 2-1. 

Fatbat asking about the number of runs ie 16, does seam enough for a full custom tune

Thanks lushy and ando. Will speak to tuner about issues when I get a chance.
Lushy, how would the dyno weather station settings impact the tune?
Can I also ask for your advice as to the possibilities/cause of the dipping torque curve?

The weather station should not affect the tune, just the dyno graph. It is adding 6% to the dyno reading,due to "weather conditions". The readings from bike to bike and day to day will not be comparable unless one check the Uncorrected box and takes into account the conditions. 16 data runs is not really enough. There is 11 lines of TP data on each cylinder, so the minimun should be 22 if it is a perfect world. Could also be that some were deleted on the way thru. I do that a bit or one has to troll thru heaps of data to find stuff.

Thanks lushy.

Re the early dipping torque curve, is this to be expected for this cam? Won't get to ride it any length of time until Friday. 

Hi there, I recently had fitted a SE Stage 3 Kit to my 15 FXDWG and was well impressed with the result. Once fitted and run in for about 500ks, I had Deano at ThunderTech dyno it - just to smotth out the throttle. 

The Cams fitted were the 259e cams - found them to be very responsive from about 20% throttle onwards and encourage the engine to rev freely, however I was chasing the additional Torque, thats what pushes the bike quicker. The stage 3 kit definitly increased the nose out put. Not over the top but close. The engine work was done at approx 2500ks - done 5000ks now and has loosened up very nicely. Real pleasure to ride now, more aggresive but still an absolute pleasure to ride. Often ride upto 350ks a day when I go out and find it hard to go home at the end of the day. One consulation - Fuel Range - Dropped about 60ks a tank down to 200 odd ks to tank - small price to pay 

The dyno results attached.
