08 Ultra 103" SE255 cams Fatcat Quiet baffle

[ceraaa42]

In my opinion this is the best bang for the buck out there for a bagger.

I bought the SE 103” pistons with barrels, 255 cams with gaskets kit. List price $749, Zanotti’s at about $630 shipped. I had the bike in for a warranty oil leak at the bottom of both barrels so it just cost me the labor to change the cams and a retune. The work was done at Latus HD.

When they had the heads off I picked them up. Took the valves out, cleaned all the powder coating paint from the combustion chamber, ports and polished them smooth. Both exhaust valves were not sealing at about a half-inch area. I lapped the valves in to a total seal, reinstalled the valves with new seals. Total time, about 5 hours, cost $14 bucks.

I talked with Mike Stegman before and he said not to put the SE head gaskets in due to increased compression with these cams can cause pinging. So they just used the gaskets that came with the kit.

Riding impressions are; it will just about idle from a stop, pulls hard down low and starts to give up about 4500rpm just as the dyno sheet shows. A perfect fit for my riding style and it really should be this way from the factory. In the Screaming Eagle bikes it pretty much is. Riding at 70mph in 6th gear yesterday, rolled the throttle and it was right to 90 in a heart beat.

If a person can do this build themselves, they can get over 105tq including the tune for about $1000. My last built made 109tq and cost 3 grand more, that’s a bunch of money for 4 lbs of torque.

It looks good, but if you had used a Pro pipe...........

I have the comments about I may have poor fuel mileage due to Latus setting the fuel trim at 13.

Started out at 29mpg in town miles, now at about 700 miles it's up to 31.

No idea what the hyway miles are yet.

Oh, sorry Jeff, I couldn't live with the Pro-pipe, it's just too loud for me. The Fatcat with quiet baffle went up quite a bit with the build over stage I. I wouldn't want it any louder or I'd be back to ear plugs.

Your better off to spend your money of a gear drive cam setup and have the heads ported and polished by someone reputable. That'll get you more bang for your dollar IMHO. Add a fuel management system and a good 2 into 1 pipe and you'll have a blast on it. That can run 2K-3K depending on what you have done. Spend another 2K for a quality big bore upgrade somewhere down the road to get the max out of a build. Best to talk to the builder sponsors here on the forum than with your local dealer. They specialize in parts that are matched to accomplish a set goal. Dealers are only out to pump their Screamin Eagle parts sales and IMHO their cams are not the best choice for many builds.

That's a great bagger build, good bang for the buck. Curious that the milage would be that bad. Was it normal before the build?

Not sure who your comments are directed towards. My bike is done, has wonderful power and didn't cost multi thousands of dollars. As I said, if you can do this work yourself you could be in it for about a grand. That is a lot of bang for the buck.

I'm fully aware I could have spent the bucks for gear drive cams (say $600), cylinder head work (oh, $900), gaskets ($100), misc ($200), and I have spent the big bucks twice (like 3-4K each). And you are right, it would be 2-3K more. Would it rev faster, yes. Would it make more power, yes. Does mine make great power for an everyday bagger without spending a lot, yes.

Milehog; It was getting about 34 in town before the work. I talked with Latus about the mileage and was told when it's completely broken in it shoud get better, and has some. We'll see. I could also have them lean it out a bit also, but I'll wait a couple of thousand miles first. I also want to wait until the warm weather incase they need to adjust it for pinging. So far there has not been any ping, crossing fingers.

WHY?

Why do I need to spend so much, to get a engine that will not last as long, have more power then I need, get less miles to the gallon, and make more vibration?
And of course if you do all that, well then you need a stronger crank as well, heck why not just buy a new bike and replace the engine with a S&S 120?
At least you will get some warranty with it.
But after all, it's only money right?

BUT this it not the point either, the question becomes, how much power do you really need?

Chris's build would make 90% of us quite happy, get us better mileage and still keep us in warranty.
We may not be winning dyno contests, or a drag race, but who drag races a tour bike anyway?

Diggerpine here; Ceraaa42, those dyno numbers look good for the money spent!

I just had the Stage ll SE 103 BB Kit installed by the dealer on my 07 RG. I don't have a Fuel Pak and am running the CVO type muffler slip-ons that came with the kit. I'm curious as to what improvement the upgrade has accomplished. Currently I'm trying to find a good dyno shop to check it out.

Ride Safe!

I need more information about your kit. Was this the same as mine only with the exhaust? Did you have any head work done? What are you doing for fuel adjustments right now? I hope something or you are so lean it most likely will cause engine damage.

Hey Chris, the "103" kit I got for my 07 RG is the SE Street Legal BB Stage II Kit for EFI Models (#29907-07). The kit includes (SE-255 cams, BB cylinders, flat-top pistons, clips, HP clutch spring and all gaskets and mounting hardware.) This also included the SE Stage I Air Cleaner Kit and came with CVO style catalyst mufflers to replace the stock mufflers. Dealer recalibrated ECM for proper installation. (Engine can rev up to 6,200 RPM)

No head work was done. The stock valve springs are adequate for the .550 lift of the SE-255 cams. I'll ask the dealer what was exactly done to the ECM for recalibration. As far as any fuel adjustments, I haven't done anything to it. (yet) I haven't noticed any increase in temperature and the engine sounds and feels good to me. Hope this answers your questions!

Ride Safe

If you were to get a better set of slip-on's and have it tuned with a SERT, I would believe you would find more power is available with no other engine changes. Also when it gets hot out you might find hot starts to be a real problem with the dealer installed download. Mines not great even with the SERT, but I was warned in advance by the turner and he will make adjustments if necessary. He also advised me to listen for engine ping when it's really warm.

Diggerpine here; Just got back from a trip to Las Vegas! The weather was HOT! I didn't experience any hot start problems and the only time it pinged was when I started off in third gear at a stop. I kept the rpms between 2700-2900 in 6th gear and going above this, it didn't ping. I plan on getting the bike in for a PC III installation in the near future. The tuner informed me that he will be calibrating every 5% of throttle up til 50% or so. Going beyond that might affect the temperature of the engine and also 85% of normal riding requires less than 50% throttle. When I get this done, I'll be able to post some numbers.

Mr. Diggerpine,

Did you ever get your bike dyno tuned? I'd be interested for a comparison for both power and fuel mileage.

I know you like Vance and Hines stuff but why specifically should he have gone to a Pro Pipe?
