my 1125 Cr has been down since june of 2012. Today it started up again. A fellow badweber and myself had to rebuild the engine due to debris found on an oil change. I want to give shout out to Will for helping me out so much with this rebuild. I couldn't have done this with out him. now some pics: The debris that caused the rebuild:  The Tear Down:   This would make a legit big wheel. haha         The rebuild:      The fire up (click on the image for a video)  Bike all buttoned up  | ||

What was the cause of the debris that you found while doing an oil change? What was the most difficult process of the teardown/rebuild? Did you have any wiring issues once the bike was buttoned back up? Any mods done while you had it apart? Sounds really good. I'm sure you learned alot and thanks for posting this up. | ||

Yeah, I'm also curious what type of debris would cause such a dramatic event as an engine rebuild to be required. | ||

Hey Devin, the bike looks good. For those of you wondering, the part that caused the rebuild was half of a snap ring or circlip that was found attached to the the drain plug in the first pic at about the 7 o'clock position. At first, we hoped it was a wrist pin clip but after pulling the top end they were all intact. The only other place to look was in the transmission, which required that the cases be split. Once again after splitting the cases everything was intact. We were baffled to say the least. As far as we can guess this debris may have been introduced when a dealer did a stator change before this oil change. Steve, the hardest part was probably the cam timing w/o the cam locking tool and, believe it or not, keeping the throttle cables from binding. The only electrical issues were properly routing everything and a low battery upon startup. I'll let Devin explain anymore if he wishes. | ||

When we went to start it up for the first time it was just cranking. Will sprayed some brake cleaner in the intakes and it fired right up. As far as mods I already insulted the frame and upgraded the exhaust. The only thing left is to ceramic coat the headers. Ill do that when I graduate and have more funds. We got a new rotor nut and torqued it to the new spec. I got the led tail light and installed that. Some day ill get the ebr rotor and get the stator rewound. I did learn so much on this project, mainly from Will. It was a great experience, and I am so glad the bike is back up. I rode it to work/school today. | ||

congratulations on a successful rebuild!! hope she runs for many many miles. | ||

I'm wondering if the snap ring/circlip may have been introduced to the engine during the initial build at the factory? I've been around alot of people, me included, that have "lost" hardware during the initial build. Or, as I've also encountered, some co-worker tries to zing you with a rubber band, plastic cap, etc during an assembly process. Were you having unusual noises prior to the oil change that revealed the snap ring/circlip? Thanks for the feedback. | ||

Congrats on getting her back up and running! | ||

two seasons, I agree, accept I did two oil changes on the motor myself with zero metal shavings or debris, then 500 miles after the dealer changed the stator I do an oil change and find the drain plug in the first picture. My bet is the dealer screwed up. | ||

Nice job! Dealers.....  | ||

So you did all that just because you found a circlip stuck to the oil pan drain plug? Wow.. honestly, I would have just visually inspected the oil when changing it, and if I didn't see anything amiss, I'd have just left the bike as-is. | ||
| Mcelhaney14 |
Fleshrocket, it's more for peace of mind. I changed the primary oil on my X1 once and found half a clip on the magnet. Took it apart till I found it, prevented other stuff from being ground up and I became more familiar with my bike. But we are all different. Some of us hear weird noises and keep thinking about it and others just keep cruising. | ||

If I tear down my engine it's going back together with at least 180hp.  (Message edited by 1125rcya on January 12, 2013) | ||

^ Good luck with that. Even with a race exhaust, an 1190 kit and some other upgrades like cams and whatever else you can find for the 1125, I doubt you'll get there unless it's with NOS. You might get close, but 180 is an awful lot for just an 1125 cc motor unless of course you're measuring at the crank. 165-170 hp at the wheel, it's possible, but 180? Mmmm, not likely. | ||
| Mcelhaney14 |
It's already loads of fun the way it is. I would like to keep reliability as well. 180hp would be nice but probably not that usable on the street. As for the rebuild of this engine, I'm happy to report that Devin and I probably rode about 250 miles today and the bike seems to have no problems at all.  | ||

Wow......A wonder all of those parts went back together and worked....Looked like you had to dismantle the entire bike... |
