That's pretty good... Please post up your dyno sheet when you can.

 

How hard is the install? I always wanted to do this. I need more torque for my fat ***

 

I didn't think it was too hard.... for me I think the hardest part was removing my power duals and a close second was adjusting the pushrods with only 2 hands

 

I might be able to get 52mpg going downhill with a tailwind, but 50.5 is the best I've ever gotten on this bike. I have leaned my cruise range as far as I can without performance or heat problems (14.5-14.6) and don't know what else to do to improve mileage. I can't even approach my old carbed RK Evo, which got in the mid-50's routinely as long as I kept the speed <60mph, and even hit >60mpg twice on slow rides with a tailwind.

I have no problems with the highway mileage, but in the city it is usually 38-40. I could do better if I could buy real gas (i.e. no alcohol) in this area. The BTU's produced by this gasohol is 3% lower than pure gas and that reflects on both mileage and power.

 

The stock exhaust system is a PITA for sure. As a cheap bastard I just had to re-use the stock pushrods, and that prolonged the job 2-3 hrs. OTOH if I had to do it over again I would do the same thing. At least I didn't have to adjust the pushrods and won't need to worry about them coming out of adjustment at an inopportune moment, but that shouldn't be a problem if they are tightened properly. I used Rivera Taperlites on my old Evo and they only came loose once in nine years and >100k miles. I think in that one case I just forgot to tighten it after making an adjustment.

How long did it take you from start to finish?

 

I plan on checking the pushrods at every oil change.

It took between 6 and 7 hours... That includes the time it took for me to go buy a set of bolt cutters.

 

cmashark, well that's another good report on the 255's. And I'm getting closer to pull the trigger.It's a close one between the 255's and the HQ 500 cams. Any reports on the HQ cams? TIA.

 

I installed a set of SE255 cams about 2 weeks ago, its been too cold and wet to give it a good run, but based on about 150 miles, it was impressive. The sound at idle is much better, however louder than I had hoped. [stock pipes]. The bike pulles much better thru the entire range right up to the rev limiter. Very impressive in the 3500 to 5500 range. I had read reports that the power dropped off after 4000 rpm but I did not feel that. The gas milage was not so good, however that was due to my right wrist. I normally get between 35-45 mpg depending how I ride.

I did this change after reading ICLICK's thread on cam change.


This is a 2007 ultra with stock pipes and AC without a fuel management system. The plugs after 150 miles looked identical to the ones I took out prior to the change.

 

Wonder how much the dealer would charge to do this. Im just thinking for keeping my warranty. My dealers pretty cool if they do the work

 

Streetking, I just had the HQ 500's installed on my 08 Street Glide. They work very well, my bike is basically a stock 96" with stock head pipes, Bassani Megaphone slip ons, SE Super Tuner, SE intake/filter. It made about 83 hp/95tq. Pulls very hard from about 2800 rpm. Still needs some fine tuning in the lower rpm range, driveabiltiy, but other wise I am quite happy. Bike sounds much better at idle. Good luck with your choice...
