WaywardSon Posted January 10, 2007 Share Posted January 10, 2007 Might as well reveal the extent of my newness to the Boxer engine...as well as the depth of my ignorance I tried doing a search here and got nothing so here goes: I have a new to me 1996 R1100 RT with about 43,000 mi. on the clock. After the engine has warmed up, there is a rattle...almost sounds like a knock, coming from the engine when it is restarted. Makes no noises on a cold start...but pretty much every time it is started with a warm engine. This noise only lasts a second or two then goes away. Bike seems to run fine & I am loving it, but don't know if this is something they all do or if I need to look at something. Thanks in advance! John Link to comment
DaveyMac Posted January 10, 2007 Share Posted January 10, 2007 I would start HERE I did mine about a week ago, not that hard if ya got the Tupperware off for other work. Link to comment
sonofdennis Posted January 10, 2007 Share Posted January 10, 2007 I recently bought a 2003 1150RT with 35k miles, it made the same noise you described. A new cam chain tensioner for left head and noise gone. These guys on this discussion board helped me out by directing me to the a web site with the procedure and even part numbers to order for the new tensioner. Simple fix just takes time to step through it. Alan Link to comment
Mark K Posted January 10, 2007 Share Posted January 10, 2007 Those are the right answers, but what they neglect to mention is that there is no cause for alarm and no harm will come to your engine if you do nothing. That is a "normal" sound as you describe it. Link to comment
WaywardSon Posted January 10, 2007 Author Share Posted January 10, 2007 Thanks to all for the info...and reassurance. One of the best things about these bikes is the absolutely vast amount of info and "wisdom" available online. So many experienced wrenches who are willing to share. I for one certainly appreciate it. Thanks again......John Link to comment
GordonB Posted January 11, 2007 Share Posted January 11, 2007 Ditto, TADT no worries... Just don't ask about syn oil or tires or crush washers Changing valve stems is getting pretty poplular though Link to comment
WaywardSon Posted January 11, 2007 Author Share Posted January 11, 2007 Ditto, TADT no worries... Just don't ask about syn oil or tires or crush washers Changing valve stems is getting pretty poplular though Ain't that the truth...the crush washer and valve stem threads both surprised me with the amount of responses they got. Been lurking long enough to know better than to start another oil war If I feel the need to fight I'll just go to Jo Mamma and join one that is already in progress Link to comment
Ken H. Posted January 11, 2007 Share Posted January 11, 2007 BTW, not sure what "warm up" routine you are following, but you do know that letting a boxer sit idling is a big no-no, right? Link to comment
WaywardSon Posted January 11, 2007 Author Share Posted January 11, 2007 Ken I had gathered that...unless it is pretty cold, I usually just start it and ride off. In cold weather I sometimes let it idle for a minute or two. Not a good idea? Link to comment
flars Posted January 11, 2007 Share Posted January 11, 2007 If it is really cold, use the cold start lever to keep the idle up (so it won't stall at the first stop sign) for the first couple of minutes of riding. Otherwise, crank the engine and immediately ride off. I don't sit for longer than a few seconds, and have never had the bike stall. FI engines don't need warming up. Link to comment
Ken H. Posted January 12, 2007 Share Posted January 12, 2007 Not a good idea? Not a good idea. The issue is exhaust temperature. Especially on the RT. Heat build up around the down pipes when there is no forward movement can quickly play havoc on the plastic, electronics in the area, and more. As mentioned, ride off immediately on fast idle ("choke") then bump it off as the idle speed rises. Probably by the time you reach the first stop sign/light. Link to comment
WaywardSon Posted January 12, 2007 Author Share Posted January 12, 2007 Thanks for the advice...should even be able to remember that one. Link to comment
harleyjohn45 Posted January 15, 2007 Share Posted January 15, 2007 since idling is bad, what do you do in congested traffic? Link to comment
Reutens Posted January 15, 2007 Share Posted January 15, 2007 Switch off the engine? Rgs since idling is bad, what do you do in congested traffic? Link to comment
Jim Moore Posted January 15, 2007 Share Posted January 15, 2007 since idling is bad, what do you do in congested traffic? Good question. I think the real problem comes from people leaving the fast idle switch on while leaving the bike unattended. If I'm in traffic, I watch the oil temp. I've only seen it get to 8 bars once (in 180K oilhead miles). I turned the bike off and let it sit for a few minutes. Link to comment
