Started to build my '11 this weekend, pulled the cam cover off to check runout and with less than 2K miles had .006 run out. Couldn't believe it..Not going to build it on that weak foundation...Put it back together and going to ride it like I stole it... Cheap Ass Chinese cranks. Look on the bright side...it saved me about $4 -$5K.

Greg,
Sorry to hear about your troubles. Some wheelies should help.

Don't feel bad, you get the same crap from 'co called superior race engines' which Jim's is well known for. I personally had this experience on two of their 131" Race Engines, first with same mileage as yours and the second with 0 milage right from their sleazy grimy hands and out of the shipping crate.. :-[ Third time will either be a charm or a total strike out :nixweiss:

At a time when many industries have squeezed tolerances to extremely tight and consistent levels, H-D can't make a simple flywheel assembly as good as the ones from 20 years ago. Remind me again why I refuse to buy one of their new "wonder bikes". :nixweiss:
Just a few short years ago, .003" was the maximum tolerance for a worn out part, and new assemblies generally measured .001" or less. Maybe they need to step back a few cycles in the evolution of the parts, before ultra cheap became the one and only criteria at H-D.

Greg, don't worry buddy. .006" is a good crank. Harley says so :2vrolijk_21: .

you have another .005" to play with............

So with our current production cranks, do you guys think that they are out from the start or do they "go" out after so many miles, wheelies, burnouts, or just lugging the heck out the motor?
I can't say that I've read any of us here that actually pulled one down brand new to check out the crank, only after it's down for issues or like this case, to do some mods on the motor.
What say ye?
Curious minds would like to know...

I think most are out from the start.... A result of the current design coupled with the assembly process...

I had one measure 14/1000 right out of the shipping crate 0 miles. The first one had 2500 miles, measured 17/1000 and the hardest miles that engine saw was a one dyno tune. When you ask for a true and welded crank and you get 14/1000 run out at 0 miles, you gotta think someone has a major QC problem.....someone needs to initiate drug testing :nixweiss:

That makes me feel secure... Just like the song says....Honey I feel for ya ..but I just can't reach ya....

AMEN>>> Headed that way now...

Texas 103, If you have that much runout on your cam side, do you think you would also have a lot of runout on the primary side? And if that is true wouldn't that cause damage in the primary to the charging system etc. Would you feel it cruising at highway speeds? Just curious if someone could comment on those questions.

Maybe, bike feels smooth,runs good Getting ready to do the Run For The Wall in May ,, I'll beat the bejesus out of it for about 7500 miles and see what it does...

Mine measured out at .008 45K ago at 15K miles. I run her hard at times and at 60K she makes a lot of noise but still runs strong.

Probably a good point. - I didn't know i had any problems with my 131 until i decided to install a set of gear drive cams. After buying all parts needed, i got stated and tore into the cam chest. First order, measure run-out; WOW 17/1000. Motor ran fine, no vibrations never would have known unless i decided to install the gear drives. OK.. sent the motor to Jim's, they fixed on warranty, i paid extra for welded crank. When i got it back, proceded with my gear drive cam project and guess what? measured 14/1000. Leads me to believe they trued up crank on the bench and never even checked the block for damages done with the first issue much less if they even replaced the crank bearings. Just goes to show what to expect from a well known engine builder.. :nervous:

Greg,
They always run the best right before they blow up. :) :huepfenlol2:

Damn Harry, that's just mean! LOL!

I wonder what made them assume you wouldn't check it? The guys at Jims know full well what the tolerance should be. Your story gives me chills. A Jims 131 is not cheap... then you pay extra to get the bottom end beefed up/trued and end up at .014" out of the crate? I'd be in jail for my reaction to that. I applaud your self control.

Trust me,, there was no self control.... We'll see what happens on the third try....

Makes me wonder how a business can survive in today's economy when a THIRD try is required. Obviously quality control and customer service are not considered important enough to deliver a quality product and to hell with repeat customer business. What ever happened to exceeding a customers expectations? It's now pay more & get less.
Good Luck and hope they get it right this time.

That's enough to make a man freak the F out. Since it costs extra to get the crank welded I guess they don't feel that it needs welding? Evidently they don't feel that the crank spinning true is important either... Remind me not to buy anything from Jims.
I'm a frayed knot!

I lucked out with mine. 2011 CVO RGU. Pulled apart with a few hundred miles on it to install Andrews 54's. I measured .0015" pinion runout and was surprised as I was prepared for disappointment. Now, I hope it stays there! I was also surprised to see that my stock camplate had a pinion shaft bushing in it! Wasn't supposed to be there. Guess they were using up their stock of cam plates.

Maybe they use ones with bushing for high runout cranks, and then hope they hold together for the 2 yrs ? :nixweiss:
