117 needs connecting rod bearing at 6K?

Someone else said it earlier, bad valve guide! I dealt with the same problem, mine started at 300 miles. Took it back to the dealer (now gone) they tore into it and said it was fine. Rode it for a while till it drove me crazy then took it to another dealer, he said he knew exactly what it was and since I had a warranty I told him go for it. 6 weeks later it had a new top end, he inspected the bottom end and said it was perfect. Of course it still ticked like crazy!

Finally did what I should have done from day one, pulled it apart myself disassembled the heads and found both exhaust valve guides were completely oval! had the valves, valve guides and seals replaced, ditched the TP rocker boxes for S&S ones changed the cam to a 600 and now I have 23,000 miles and it doesn't tick at all.

You have enough room to pull the heads without taking out the motor but do both at once. There is a good thread on here about how to do it.
 
What bill said!

It's a lot easier than you think, tank, exhaust, intake/carb, unplug compression releases, rockerboxes, pushrods.....you get the idea. I bought an S&S book a long time ago an educated myself on v twins, I'm used to building KTM motors. V twins are nice and simple

OK. Thanks guys!!! One thing I don't understand is sometimes the noise goes away for a minute or 2. Like at idle or sometimes when I'm going down hill with the motor holding me back. Still sound like a bad valve guide?

franco called so here I am

One thing I don't understand is sometimes the noise goes away at idle or sometimes when I'm going down hill... valve guide?
Yes, I lift I am not being hammered upon by the power side. I clang a valve open I am going to be sucked upon or blown at. See the valve open and that click on the suck? A harder suck on open throttle rather than lift on a closed throttle.

See the ex valve bangs when that hot air pushes out the moment that valve is off that seat face and the tick occurs that way under load? Now, which is it? in?\ or /?ex?

Here we go with a valve guide problem:
Cutting seats - My valve spring stack is so much or I will have valve bounce I start to hammer the throttle with a softer spring pack. Do I have the guide changed and cut the seat and is this a one hit wonder production head? Do I have room to run the valve up the head, lower my compression as well? Where does my valve tip to rocker land in this I push the rocker up more. :up:

OK. I guess if I'm gonna go that deep. I might as well do both intake and exhaust guides? Should I do both cylinders? Or just the one making all the noise? Anything else I should do since I'm that deep?

Take off both heads and have them both totally redone. If you don't you will do it over and over again.
