Ok guys and gals, I looked nad searched the forum and couldnt get an answer to the specific break-in question that I have. How long do I have to vary the speed on my 2007 Nightster before I can actually go out on the HWY and do some longer trips. Around here, KC, there isnt a lot of Twisties so it is getting annoying trying to vary the speed in all suburban riding. I have 400 miles on her and have been varying the speed, keeping it below 65, etc. Why mechanically speaking do u have to vary the speed? After doing that for 400 miles can I finally take a trip that is majority HWY?

 

what does the factory say? 1000 miles?

 

The factory manual stops giving instructions after 500 miles, but the service guys said vary until 1000, and then the other service guy when i called back said 750, so i am lost

 

I rode mine HARD from day 1. never had any problems. As for your scoot, keep it up till you reach 500, then change the fluids and run her like you want to. At least that's what I was told.
( I never do as I'm told )

 

500 miles or so of varying speed NOT exceeding 50 mph is the best break-in method for the EVO. Break-in for the engine is important because the piston rings need to seat properly, the cylinders need to have proper (not excessive)expansion and contraction, and the bearings and bushings need an "easy does it" break-in for proper true up and lubrication in the process. You're almost there. It's well worth the effort in the long run for a long-lasting and strong running engine.

 

My dealer told me when I bought my '07 883R that after 50 miles its fine to "ride it, like you mean it" he said that these motors are broke in from the factory and with todays manufacturering, long term break-in isn't necessary. Now this is obviously debatable, but I did as they said and cycled gears, varrying my speed, not taking it over 65mph etc. up to 50 miles and then I rode it like I stole it, and it has been fine. So alhough break-in is a reality I wouldnt worry about sticking to the 500-1000 mile break-in to the "T".

 

see, even in the short forum posts there is such a great variation in suggestions that I can't figure out if it is okay to hit the freeway going 70 now or if I have to do 50 for another 600 miles. The book simply stops "mid conversation" with the break-in at 500. Oh well, I guess I will baby it to 750, doing 57.5 mph (middle of the 65 and 50) and then drive it normal. Oh boy, 350 more miles of soccer moms and sport bike riders.

 

So then after the 500, just ride it how I want to?

 

That is correct!

 

Be patient It will be there.
