so this happened today. sorry no pics yet because im soo pissed off. was riding along and wasnt horsing it but wasnt ridin like a granny. was shifting up through the gears and at about 60 in 4th it came out of gear because i wasnt very crisp with the shift. and it revved to the moon. got it into 5th and a loud tapping noise was coming from the motor. just a few miles from home to inspect that im not spewing oil or anything like that and made the decision to limp it the couple miles home keeping the rpm low. could tell exactly what it was it was a very misadjusted tappet. popped the tappet ports on the valve cover for cyl 4 and lo and behold half of the adjuster and the nut are missing didnt dig deep into it tonight just not in the mood. but what im thinking is the nut was loose and and when it went into false neutral the adjuster came in contact with the adjuster cover and sheared off, at least thats all that makes sense. il need to fish out the missing bits hopefully they are not in the bottom of the motor already and are somewhere under the valve cover and i can get them wothout taking off the valve cover. i have a spare otor so i can steal what i need from there but damnit. its been running so good. put over 2500 miles on it from march already. i was planning on building the spare motor this winter for my drag bike but might be building it for this bike if there are a lot of metal shards floating around in this motor, its deffinetly getting an oil change after this and a second one short thereafter.
