2015 RGS with 120ST

HI All

This is the initial or break-in tune on this bike. I'll be headed back to the dealer for the 1000 mile service and full dyno tune.

Even as it is I'm very happy:

116HP and 118TQ

Just curious as to why they could do this power run for those numbers and not go ahead and do a full dyno tune...? Doesn't make much sense to me. The bike would benefit more from being fully tuned at that point IMO.

I would assume it was the OP's choice after being properly advised by his tuner. With that few miles, he may have just wanted to see where he stood. Dyno'ing an engine that early is super stressful. I wouldn't be surprised if he had engine trouble later on due to just this # check.

This was actually my point but I don't believe the motor needs 1k miles to break in. So IF he was properly advised by his tuner he should have been advised not to do this run for numbers and wait until it had some miles on it.

That's kinda my assumption too. I can't see a credible tuner advising to run the bike that hard, that soon, but a tuner will do whatever you pay him to do as well.

Hi guys

I guess iI could have been clearer in my initial post,

This was a single pull to get a feel for the engine after the build. The bike had almost 80 miles on it by then.

I have full confidence in the dealer and their customer support, not to mention the warranty.

The dealer builds multiple 120R engines a month and I talked to the engine builder enough to trust that he knows what he is doing.

The reason vfor waiting until the 1000 miles service to do the full dyno tune is that I live 300 miles from them and I wanted to get some riding done.

As is, the engine runs smooth, no rough spots, etc... And far more butt dyno power than my last bike even though the engine is slightly smaller than it was.

I'll be headed back the weekend of the 15th to get that done.

I'll update this post then with that chart.

Glad to hear. Didn't mean to sound like I was busting your chops but didn't make since to me why he would do a power run that soon and not do a more detailed tune. Sounds like he kinda did that after all. What exhaust are you running with your ST? Can't wait to see your numbers to see where it's at. I can tell you from my own experience that the 120ST is a lot better than what most want to give it credit for. The 259E cams seem to be a good everyday touring came for that motor. My old 110" with the 255 cams doesn't even compare to the 120ST. Of courese you can always do better down the road if needed. Good luck!

Hi RGKen

No problem, I'm running the black ceramic D&D Boarzilla, love that low rumble.

I like the default cams, especially after seeing that torque curve. I'm mainly into the long distance touring so the factory cams should be fine for me for the foreseeable future.
