bongobobny Posted March 19, 2015 Share #2 Posted March 19, 2015 Maybe leaking exhaust gasket?? Link to comment Share on other sites More sharing options...
ricksbike Posted March 19, 2015 Author Share #3 Posted March 19, 2015 I listened to the exhaust with stethoscope,could not pinpoint any leaks,also mileage is good-40-42--and performance hasn`t changed,I`m stumped. Link to comment Share on other sites More sharing options...
bongobobny Posted March 19, 2015 Share #4 Posted March 19, 2015 OK maybe a bad o ring on the carb boot to the head... Link to comment Share on other sites More sharing options...
Neil86 Posted March 19, 2015 Share #5 Posted March 19, 2015 Airbox drain hose off or crankcase breather hose loose at airbox. Link to comment Share on other sites More sharing options...
MasterGuns Posted March 19, 2015 Share #6 Posted March 19, 2015 Check #3s slide and diaphragm. Link to comment Share on other sites More sharing options...
cowpuc Posted March 19, 2015 Share #7 Posted March 19, 2015 LOTS of great advise so far.. Pull the air filter and side covers. Crank er up and watch slide's bounce - see if you notice any differences in movement. Pull headlight fuse, run in dark garage at night and see if you see any electrical leakage - plug wires especially. Also might wanna check resistance on plug terminals and double check exhaust leaks. Tight valves can cause strange noises too.. Maybe make a video for us so we can actually hear what your hearing? Youtube it - and post it up.. If we cant help you after all that, bring it to Don's Maintenance Day.. If the really smart people show up I bet they can figure it out and you wont have to walk home!!

ricksbike Posted March 20, 2015 Author Share #8 Posted March 20, 2015 I`ll recheck all of these suggestions,by the way Puck,removing the filter and watching the slides was the first thing I did,just had a Senior Moment and forgot I did that--Thanks again for the suggestions.

cowpuc Posted March 21, 2015 Share #11 Posted March 21, 2015 Maybe leaking exhaust gasket?? Bongo's initial thought is stickin in my pea brain.. Start it cold, with it idling put a welding glove on, grab the headers one at a time and try to move em - see if you can pickup any noise..

ricksbike Posted March 21, 2015 Author Share #12 Posted March 21, 2015 OK,rechecked all hoses slides,I noticed yesterday that when I started it,there was no abnormal noises,road about 5 miles got to operating temp,noise returned,listened with stethoscope-noise loudest at #3 cam cover.still have to check under cam cover(have to buy new gaskets first) by the way ears don`t flap,I wear a helmet and haven`t had a burrito in a while(could Have Been My homemade chile though--LOL):starz: Link to comment Share on other sites More sharing options...
