So I finally got a chance to work on my rear S2 brakes on Saturday, preparing for Sundays run up to Paradise on Mt.Rainer. Replaced the rear master cylinder, installed a new brake line, and new pads. Had a hell of a time getting the system bled and didn't finish up until 10:30pm. I had all the body work, rear wheel, and gas tank off and after I had them all back on I fired the bike up to make sure it would start, then went to bed. We were up at 3:30 am for an early start, were getting on the bikes at 5. Sun wasn't up and we had the outdoor lights off so it was dark. Just before I hit the ignition I remembers that I had not turned the petcock back on. I took off my glove and reached down and did that, put my glove back on and reached for the key, then realized there was gas pouring down the engine. DOH! I had forgot to reattach the fuel line! I quickly reached for the petcock but my glove was too bulky, so I leaned the bike over onto the sidestand so I could take care of the problem. Too late I remembered that the sidestand was up, so in slow motion and absolute silence the bike tipped over, just missing my wife who was next to me sitting on her new S3. I jumped off the bike and stood it up, turned off the petcock, looked at the huge pile of gas under the bike, looked at the broken turn signal, the broken off clutch lever, the gouged fairing, and then it got loud. Fortunately I had my helmet on and Macy had earplugs in, so all she heard was a muffled *&^%*%^#$@#$%^*)(^*$^%*#&%#^&%*&^^$^(&*_. I had a set of spare stock signals. I reattached the fuel line, installed the old signals, decided I could still get three fingers on the remaining section of clutch lever, so we were good to go and on the road at 5:30am. Kind of a late start, but oh well, I felt so stupid I just didn't care. Now a question, which I may have to also post up elsewhere. It was a hot day. Coming down back off the very crowded mountain (free admission weekend), it was very slow bumper to bumper traffic. 80's at the top, then 90's and on up to 100+ by the time we hit the lowlands. Macy's 2002 S3 begin surging at speed, and refusing to idle without dying at stops. This had also happened on friday when it was really hot. The heat may be coincidence. I am going to check out the throttle linkage and the butterfly plate in the throttle body today. Also hook up ECM Spy and check for error codes. Any other ideas where to look? Shane | ||

check the temp sensor on the rear cylinder, maybe do a TPS reset... | ||

What you didn't dive under the bike as it fell, while your wife screamed "SAVE THE PAINT"? My '02 S3 was acting up two weeks ago, and threw an error code for the temp sensor. Replaced sensor (there is a new temp sensor kit out) and it is happy now. I did get a engine light and pulled the stored code to see that it was the temp sensor. | ||

I was sitting on the bike, so mostly I just tried to keep my leg from getting trapped. I think I solved the S3 problem. I did a TPS reset, and found the AFV was at 127%. I reset that to 100%. I think that may have been the problem. Bike seems to run great now, need a real hot ride to make sure. How does the AFV get changed on it's own? | ||

It is amazing how heavy a 500lb bike gets when it hits that point of no return. I pulled the no kick stand down trick the other day in the garage with the S3. I managed to get between the bike and anything hard...darn that hurt!!! AFV http://www.badweatherbikers.com/buell/messages/384 2/347502.html Could be your changes in elevation and then the slow (low rpm) traffic. | ||

AFV will change constantly,that is what it is designed to do. 127 means bike was running lean somewhere in the "learned fuel" area(very small in a FI tuber) and the bike added 27% more fuel to make up for it. So then you probably had some nice rich spots,explaining the surging etc. And the high temps may have exacerbated the problem. Take a look at your AFV after another ride in normal conditions and see what AFV is, normal should be between 95 and 105. And with ECMSpy you can look at what temp sensor is saying to see if it is acting correctly. Depending on add-ons-exhaust etc and age/mileage of bike--all can affect running. And check to see you don't have intake leaks, seals are maintenance item and the vacuum port on bottom of intake manifold being open is very common. | ||

Shane, I am glad it was not more serious... When that beast starts going there is no stopping it.. DAMHIK Frank |
