Hoist, sounds like you went with bigger bore cylinders, 113...120? Or else why the new stock pistons and barrells. I too would like to now the specs. on the cams....new brand, duration ect...And if you can answer this for me, in all your research I guess you determined the heads needed some reworking, and would changing to the SE 50mm tb do any good for us normal folks with small mods. And can it be installed on the SEroadking3 with the cruise control. And can the SE 50mm tb be improved on with bigger injectors? Please do tell.....any advice would help.
Hey KD/Ron, it's still 110"! I used stock barrels and pistons. I knew there were difficulties w/the dealers getting parts. So I made sure I had the parts to be w.....ty'd, when we built the motor. I wanted to have a completely new top end, with all the best bulletproof chit in it. The cams were matched to the design of the head rework and the new compression, 9.8:1 corrected, by Wes Brown at Cyclerama. I don't know how they would respond in a stock engine though. I worked very closely with Wes as were determining the best components for this project. The whole process has been fun and extremely interesting. Thanks to Harry for helping out, and turning me on to him!
The 50 mm works fine, is compatible w/cruise control and I would higly recommend it, even in a stock engine. And the stock injectors are fine for stock engines. We tested the stock injectors vs. the 4.89's w/the 58 mm. It seems the stock ones are better w/this build too. It would help for sure, but I would do cams with it. These engines gotta breathe!!! It seems they run so much more efficiently when you put gobs of flow thru them.
If you don't want to do much with your bike, but want to perk it up and get it running cooler, and not get custom matched engine components for the maximum performance output, here's what I would do to every 110, as a minimum:
50 mm SE or 51 mm HPI Throttle Body w/ stock injectors, SE 251 or other similar decent but not crazy cam, Cometic .030 head gaskets, S&S Tuned Runner Induction Intake and D&D FatCats. THEN GET YOURSELF A PERFECT TUNE!!! That's probably the most important part! With a good tune, you'll be getting between 115-120 Tq and 105-110 HP. These have the potential to be great engines. Get the top setup right and hope the bottom holds together!

We're still going racing Ronnie!

Hoist!
