For over 35 yrs, I've built engines as a hobby, for myself either to race or to use as a daily driver for various vehicles.

I've not had any trouble at all using the techniques in that web-site. And I've done it that way for longer then the web site has been active.

As for my new vehicles (over 16 total brand new in my life time), cars, trucks and motorcycles... new off the show room floor. That includes this RK, I've done the same to it.

I have never had any problems.

As a disclaimer: IF YOU don't feel comfortable doing it the way the web site has indicated. Follow your owners manual. I am not nor is that web site for any damage to the engine since it was not done in my own care under my direct supervision by me. As is inlife, its all at your own risk.

 

Thats the way I did mine. Sounds a little scary and is quite a departure from the owners manual. I did a 10.5 comp, HQ 103 on mine and have about 2000 miles on it so far. Doing great!

Guess I am a believer now too.

 

B/S Alert.

 

That's the way I broke mine in! I didn't go crazy with the rpm's until after 400 miles but the first 100 I would run it up to 4000 and let off, run it up to 4000 and let off in 2nd and 3rd gear.

 

After an initial 600 break in miles on my new glide, I added a 107 kit to my bike and we broke it in on the dyno. After getting it up to operating temps, we put it through6 sepearate dyno runs varying the T/P from 30 to 70%. It was always cooled by fans between and during the runs, and the power this thing has now is nothing short of amazing. Full Dyno pulls come in a couple of weeks. Hoping for 120+

 

I looked for something like this when I first got my bike and didn't find anything before I started riding it. I also went easy the first 3 or 4 hundred miles but after that I did alot of highway riding where I would bring the RPM's up and back down for about an hundred or so miles. after that I started riding it like normally do. I am now at 2500 miles and she's running really good, no problems. I only wish I had changed the oil at the earlier time than a 1000 and I would have held off on the synthetic.

 

I used this method on my Nomad. The problem is you don't really know if it works or not. I couldn't do it on my Ultra because they had already ridden it about 8 miles first and the traffic was bad on the way home. The whole idea makes perfect sense though. Another one of those synthetic oil things, you just don't know for sure if it works! T.

 

No BS, that is 100% true and proven. It's the way many break in engines from bikes to race engines. That old "Stay below 40mph for the first 1000 miles" is BS. The rings are well on their way to being seated before your bike leaves the factory. In the old days when engines were built with very loose tolerances, you did have to take it easy or you would get a bad rind seat on a piston. Now, since engine tolerances are so tight, the rings are seated when the last guy on the assembly line takes a bike and puts a battery on it and fires it up for a ride on a dyno.

 

I'm of the opinionmodern enginesprobably arealready broken in when you get em. I just ride em like I intend to ride em from now on.
