We just returned from 6 days of riding, 987 miles total. Bought my '07 CF1000 SP late last season and only put 135 miles on it before parking it for the season. This season no more then got underway, and I had to take it to the dealer for the ECU reflash. 336 miles on the sled the day it went to the dealer. When I get the sled on the trail again, lower rpm range feels a bit crisper but the rest of the power band just flat sucked. I was extremely disappointed with the sleds performance. Especially while getting spanked by my '06 CF700. Definitely not what I had anticipated from the 1000.
Well, during this last week of riding I had an unusual experience, when the odometer rolled the 750 mile mark, the engine bogged, quits, starts again, quits, and does this a couple of more times. Finally it fires up and runs like nothings wrong. I put about another 700 miles on it in the following days without any recurring symptoms. It ran like it has never ran before. Finally had an area where I could open it up with out putting anyone other than myself at risk. 111 mph and climbing, there was more but I ran out of comfortable room. This thing has never run so good before, it flat rips! Another thing I noticed was that it was easier to break the c-note if I gradually and steadily squeezed the trigger, rather than just mashing it to the bar. What I found was that by the time I reached the c-note, there was still more thottle remaining. Whereas, if I just mash it to the bar, it seems like it takes an aweful long time to climb from low 90s to 100+ mph.
Now, for the money though, my '06 CF700 followed close behind at 106 mph. Both sleds are bone stock.
Has anyone else ever experienced this 750 mile phenomenom? Is it just a fluke?

My XF 700 did kind of the same thing. Had trouble passing 95mph, after about the 750-900mi mark I can now pull 109mph on GPS. <shrugs> Every engine needs a break in period I guess, wear some metal out of the DD, work the track in, all that stuff adds up to mph. I don't -think- these sleds have a burn in chip like doo uses. But I could be wrong.
