transmission problem update

Hi Patrick, maybe ask your guy to check the balance shaft bearings. Especially if you hear the noise on the rhs rear of the engine. Good luck, as the others say. Hope you find it.

here are some answers to your queries
# 1 in third at 60 mph no metal slapping shift in to 4th if under 2500 rpm nothing if over 2500 slapping goes on ( I mention it is intermittent however increase RPM slapping gets more often and more predominat)

#2 if at 3000 rpm in 4th or 5th and close throttle slapping goes away ( it remain only when loading the engine if I cruise on a flat road at 2500 or above and not loading the engine no slapping but openin the throttle or climbing a hill ( hence loading the engine) will start the metal slapping

#3 opening the throttle under the above conditions will increase the frequency of said slapping rolling it off will see slapping disaepper whether in 4th or 5th

I am going to ask the wrench to check the clutch since he has looked at everything else currently he is checking the rear end and output shaft I guess we will see if all the parts ordered make a difference if not I will just let it fly till something break/crack/ explode and see wtf happens ..
I have a big trip in 2017 all summer in europe with my roadster I sure do not need the aggravation

Loose timing chain?

ok so it coincides with engine loading at mid revs onward in 4th and 5th, and gets worse with revs.

is your engine modified? does it slip out of 4th and 5th?

ok. is there a blip/bog/cough/stutter in the engine's running or rear wheel running when a slap noise occurs?

seems very strange that this issue hasn't left a mark on anything inside the engine...

the 2 occasions i've experienced with a slap/whack noise in engines were when (a) a bolt vibrated loose and got whacked by a pulley spinning and (b) a faulty sprag clutch which would not engage until after the starter was spinning, causing a metallic whack.

I've been thinking of your problem. How are the rear wheel bearings? Could they be starting to seize? I know it's a long shot. Good luck.

could be?
but the strong slapping felt through the footpegs would more likely indicate it has to come from the engine block stay tune we shall find eventually I am lucky though my mechanic is truly experienced and he also want to look at the rear end as well I dropped off my last moly60 tube for him to lube the shaft.
