whilst .075"is not good it is still in spec, they bumped it up a few years ago presumably so they didn't need to have great manufacturing quality.
If it's .075mm then it is pretty good

if it's .0075 anything then you have a real good stock one. Did you check the cam plate for any signs of wear?
none of which helps with your vibration issue

0.075" is 75 thou 0.0075 is 7 and a half thou 0.00075 is three quarters of a thou 0.75mm is three quarters of a mm (30 thou) 0.075mm is one thirteenth of a mm (2 thou) 0.0075mm is two tenths of a thou . i dont know anything about the crankshafts but i think the allowable tolerance is 0.015" (15 thou) what i would like to know is what does scissoring the crank mean? never heard the term before. cheers beags. ps if another two people join the forum tonight i win the comp. come on ya bastards!

stop chuckling pauly and explain what scissoring the crank means please

so what does scissoring the crank mean pauly? if you dont know just say "i dont know" or you can go and google it and become an authority on the subject as usual.

thanks for that hilly but i am still none the wiser. can you elaborate a little bit? otherwise i might have to go googling myself but i would prefer not to

righto hilly. i just assumed the crankshaft would have been one piece of drop forged metal like every other crankshaft i have ever known about. it would want to be a fukin tight interference fit if your joining three shafts together eh? do you reckon they use loktite when they press them together? modern engineering is something i wont complain about cos most of its good but i am going for a run on my 2002 fatty tomorrow and i would have prefered i didnt know my crankshaft was sweated together. i wont worry about it too much though. only cos i am not paranoid. paulyboy me old mate, you should hold back cos i can see you making a cunt of yourself again

This ain't a half bad explaination.

and,,, for an out back, couple of beers and a barbeque type explaination, this one works well,

"Take two paper dinner plates and drive a pencil (acting as the crank pin) through the two plates near the edge somewhere. Move the two plates (acting as the crank halves) in opposite directions with the pencil being the pivot point and that's scissoring."

 

Food for thought Brothers,,,,, not many people have figured it out and not much is discussed about it,, but think about it.

Interfearance press fits are quite often chilled or cooled down so they can be assembled, right, so when the components are cold they fit together easily and are not as tight as they can be,,,,

On the other hand, if the components are heated, or in the case of metal are expanded,,, you won't have a snowballs chance in hell of assembling them,,,, so what you think happens when an assembled set of components are heated,,,, or in the case of a twin cam crank, up to operating temperature?

If you're good at guessing you'll guess that most twin cam cranks scissor when they're stone motherless cold and not fully expanded by temperature,,, and little Johnny twists the throttle round to full tilt to make big bangs in the jugs on top of the pistons before the donk is at operating temperature.

Reckon that should just about convey my opinion, and hopefully prevent a few un-neccessary scissored cranks.

little Jonny wanted to ride my bike once lucky I said rack off

thanks for that rider. i read the link and i am now a little bit wiser. thanks hilly
