A few questions of  things I am wondering about if I upgrade from my bone stock 96"

1) With any upgrade 103 or 107, should I upgrade the compensator on my 2010 first? They are bad from what I have read online in that era?

2) Should I get rid of the automatic primqry chain tensioner and replace it with a manual one like I had on my mod evo sportster?

3) Is there any truth about the cranks possibly have lots of run out in that era? Again you can't believe everything you see/read online.
Did the moco raise the allowed tolerance on cranks in that era to have less warranty claims?

I am wondering all this because I want to make sure the foundation I start upgrading is solid and won't cause issues up the thread with increased displacement and torque.

I would rather wait and fix foundation issues first if any of these things are correct. However if they are, then the question of things like do I go with SE compensator or Baker? SE manual primary adjuster or Baker?

I know guys lots of questions but I don't want problems down the road even on this stock 96"

The worst problems with the flywheel assemblies (crankshaft) occurred in 2007 and 2008, right after they redesigned the primary for the new Cruise Drive.  At that time they also redesigned the crank and the process used to assemble them.  So many flywheel assemblies failed that Harley changed the maximum runout tolerance measured at the pinion shaft from .003" to .012", in my opinion to keep from having to reject a huge percentage of their parts and pay a huge amount to replace flywheel assemblies in already produced bikes.  We hear much less about crank failures these days, but that doesn't mean the current stuff is as good as the earlier stuff.  I, and many others, recommend that anyone considering investing in engine upgrades at least measure the current runout of the crank before spending a lot of money on other things, especially if they plan to significantly increase output.  It makes a lot of sense to just automatically upgrade the flywheel assembly if you plan on a major power increase.

Thanks for the response. When you said"t that time they also redesigned the crank and the process used to assemble them."
Is the 2010 subject to this process?
Or was it 2007-2008 only where the issues were?
Is that high tolerance what my 2010 is subject to as well?

The process was automated and still is the same. The press fit improved after 2008. Doesn't mean there will be any less run-out just means it has a better chance of staying put. The latest revision of the compensator is 2014. Replace yours after inspecting then decide.

Does the 2014 fit 2010?

Yes absolutely. It is just a revision
