[QUOTE="hppants, post: 1400814, member: 27852"] On all 3 of the FJRs that I've removed the coolant pipe on (in each case it was the first time the coolant pipe was removed on that bike), there was a "snap" when it broke loose, although thankfully, I didn't have problems getting it out. Lots of lock tight on those bolts from the factory. In each case, I did not run a tap in the cylinder head, but I did lightly buff the bolt threads to remove all residual lock tight. Not really sure what Yamaha was thinking there - the squishy of the O-rings will act like a lock washer against vibration. No need to get stupid with it. Next time I'm in the shop, I'm gonna check out my allen sockets to see if any of them are rounded at the ends. If so, those are getting chunked and replaced. Regardless - I'm glad you averted what could have been a disaster. I enjoyed reading the suggestions from others, and I'm placing those in the bank for future reference. [/QUOTE]
