Ken H. Posted January 27, 2008 Share Posted January 27, 2008 The photo pretty much tells the tale: $2300 in parts, and I would guess about 50 personal manhours later. Now to get 600 miles on it under 4000RPM and readjust everything. Not an easy task this time of the year in this part of the country, the roads are a mess. Oh well, I'm just glad it runs again! A big thanks to everyone who offered advice and encouragement. The rest of the tale is here: Can the Piston be Salvaged? Resurrecting My Dead Engine, Link to comment

MickFinn Posted January 27, 2008 Share Posted January 27, 2008 Well done. I wish you many, many, more miles of trouble-free riding. You deserve it after your ordeal. Link to comment
Tony_K Posted January 27, 2008 Share Posted January 27, 2008 Parts is parts. It's all about the person willing to work with them. Well done Link to comment
Joel Posted January 27, 2008 Share Posted January 27, 2008 Really? How do we know the tach wasn't just stuck on 1k rpm? Congrats! I think your "Tech Mod" title will now be carved in stone. Link to comment

kcscout Posted January 27, 2008 Share Posted January 27, 2008 It's 59*F right now... no reason why you shouldn't be able to knock off those 600 miles today. Congrats! Link to comment
smiller Posted January 27, 2008 Share Posted January 27, 2008 Good job Ken. BTW do you have any theories as to why your bike sustained the damage it did? I've heard of countless examples of low-speed drops with these bikes but I can't remember even one that resulted in internal engine damage. Could there have been a raised chunk of pavement or something that nailed the cylinder head? Link to comment
Mike05 Posted January 27, 2008 Share Posted January 27, 2008 Congratulations on a job well done!! Further proof of why you're my "go-to" guy with all my questions. (Thanks, as always) Link to comment
Ken H. Posted January 27, 2008 Author Share Posted January 27, 2008 BTW do you have any theories as to why your bike sustained the damage it did? I've heard of countless examples of low-speed drops with these bikes but I can't remember even one that resulted in internal engine damage.Yeah, tell me about it! And it was a rather mild 15 MPH or so low side around a city corner. Nothing seemed to ever really add up. The damage was consistent with the cylinder itself having been pushed backward. For example the dowel guides in the oil passages between the block and the cylinder were deflected/bent rearward and the guild pin between the head and the cylinder sheared off, clearly in the direction of the cylinder having moved backward. OTOH there was no external damage to the fins on either the head or the cylinder. Heck in the end I had some minor work done on the head itself and reused it. But there was a big dent in exhaust pipe right at the upper curve downward. The bike ended up against a curb, so I suppose when it slid into the curb, still running the exhaust pipe might have hit hard enough to case a momentary deflection that then crashed the still moving piston. But overall it's really a mystery. Like you said, usually a boxer is indestructible in a low side. Link to comment
Paul Mihalka Posted January 28, 2008 Share Posted January 28, 2008 "But overall it's really a mystery. Like you said, usually a boxer is indestructible in a low side." Boxers are indestructible in a low-side if they are sliding, not if they hit something solid like a side walk edge. In that case the only thing that may help is a set of good solid old fashioned crash bars but those might bend the frame or damage attachment points. Link to comment
Twisties Posted January 28, 2008 Share Posted January 28, 2008 Sweet!!!!!!! That's really fantastic! Way to go. You must feel great. Be careful on those roads. Jan Link to comment

Ken H. Posted January 29, 2008 Author Share Posted January 29, 2008 Is that really a carbon fiber dash surround? Yes, it is Ztechnik's. ZTechnik Yes, before anyone says it, I know, non-functional, non-environmentally friendly farkle... Link to comment
Ken H. Posted January 29, 2008 Author Share Posted January 29, 2008 So how did it feel as you were about to thumb the starter button? Well I had turned it over by hand a few times (with a big socket on the crankshaft bolt) and then with the starter before hooking the fuel pump back up, so I felt somewhat sure I had it back together right, but still... And it was 2 AM so I thought about resisting until the next day (I live in a multi-family condo) but in the end I couldn't resist find out. So I fired it up! Link to comment

Ken H. Posted January 29, 2008 Author Share Posted January 29, 2008 So, do you trust the bike?I don't know, good question. Probably not entirely, but I've sort of got a wait and see attitude about it at the moment. On one hand I'm pretty confident the work I did is right, OTOH, is there some hidden damage I missed? I kind of figure if there is still an issue it will show up pretty fast, e.g. in 1000 miles/km, not take 10,000 to reveal itself. Besides in reality I have little choice, as the weather improves I'll just ride it to and from work each day and see what happens. Link to comment

Jim VonBaden Posted February 4, 2008 Share Posted February 4, 2008 Nice work Ken! Was that total including all damage, or just engine damage? Jim Link to comment
Ken H. Posted February 5, 2008 Author Share Posted February 5, 2008 The $2300 was everything. Engine only about $1600 I'd guess. I haven't actually categorize and added it all up. Too depressing... Link to comment

Joe Frickin' Friday Posted February 11, 2008 Share Posted February 11, 2008 The photo pretty much tells the tale: Wow, missed this thread. Congratulations, Ken! Sucks that it had to be done, but finishing a big DIY project like this has gotta feel good at this point. Link to comment
Ken H. Posted February 11, 2008 Author Share Posted February 11, 2008 So? There was some warm weather there for awhile, right? Yeah, I got a couple of days in to/from work before it snowed again. I've got about 200 miles on it so far. It's pretty vibey. I'll have to see what it's like after I make another pass through it all at 600. In particular I think I've still got then rocker arm end play all wrong. Also I've been mulling over about how much one side being tight and new, and the other side having 28K on it has on vibration / imbalance? Link to comment
Paul Mihalka Posted February 11, 2008 Share Posted February 11, 2008 How about a compression leak-down test on each side? Link to comment
steveknapp Posted February 11, 2008 Share Posted February 11, 2008 Also I've been mulling over about how much one side being tight and new, and the other side having 28K on it has on vibration / imbalance? Probably a good theory given how much nicer a broken in BMW motor feels than a new. You could go crash the other side? Link to comment

Ken, I hope everything works itself out for ya. You certainly are due quite a few years of trouble free riding after partaking in that mechanical adventure. Link to comment
Marty Hill Posted February 11, 2008 Share Posted February 11, 2008 Hey Ken, If you need another bike, my '07 will be for sale in nov./dec. I can deliver it to Ron's x-mas party cuz that's when my new one should be ready to be picked up. Hey Ron, you are having a party, right? Link to comment
Ken H. Posted February 11, 2008 Author Share Posted February 11, 2008 Hey Ken, If you need another bike, my '07 will be for sale in nov./dec. Actually I was going to get around to asking you about your '07. But Nov./Dec. is a bit far off. If I was going to switch I'd probably want to do it this spring. Thought you were going to but a 650 soon? Link to comment
Paul Mihalka Posted February 11, 2008 Share Posted February 11, 2008 "Thought you were going to but a 650 soon?" Marty would have the F800GS now in March if they would come, and you could have his R1200GS. Link to comment
