How Important is This??......

Found out a couple weeks back that the "run-out" on the crank is .004 out. So the question becomes should I send out the crank and have it "trued"? I would like to do an up-grade kit from this company, http://www.head-quarters.com/html/tc113_kits.html at some point. I've already installed the "HV" camplate and oil pump from Feuling and it's nice. But the crank is only .004 out, so how important is it really.......

I don't like anything over .003, others will have their own opinion. What year is your bike and how many miles?

I'd go with anything Doug, Duke, or Boz (HQ guys) recommend. I've gotten excellent advice and perfomance from them. I'm on my third HQ motor and strongly recommend them to anyone that will listen.

I trust them enough that I drove (bike in the back of the truck ) 1,400 miles (one way) to have Duke break in and tune my bike. Ended up redoing everything a local independent did, but that's a whole other story.

Check out the Yahoo group they have. There is a lot of great information there and they answer any questions you might have.

In my opinion you've made an excellent choice. They have a proven 'formula' that works when followed. I sacrificed a bit of performance by not following some of the recommendations but for me it was a 'looks' thing (dual exhaust and intake).

If you're going the 113" route using Doug's kit you'll need to bore the cases for the cylinders to fit. The cases have to come out and be split anyway, perfect time to get the crank true'd and welded. I wouldn't pull the crank JUST for .004", but if it's coming out anyway there's no excuse not to.

They're pretty hard to get in touch with over the phone and try to discourage it. Try the Yahoo forum they have in the Customer help section of the web site or the tech email address they offer.

I've always had good response with the forum.

Good luck and enjoy!

At .004 your crank is probably better than half the 07 and up engines out there. Unless you plan to use gear drive cams or go bigger on your engine, I wouldn't even worry. If you do upgrade that's the time to weld and true the crank.

I asked the same question last fall.
My Indy said anything under .006" was fine.
I also asked Frank Drago, he said anything up to .0065" was acceptable.
I take just about anything Frank says about Harley performance as gospel and my Indy agreeing with him can't be a bad thing!
