I'm seriously looking at Hillside's 107" conversion for my 2009 SG. The bike will have 0 mileage, I'm tearing it down as soon as I take possession. I was wondering if it would still be better to replace the inner cam bearings or can I just leave the stock ones in?
Thanks for any information.

Definately replace with the torrington B168, no comparison to the stockers.

Wow, quick reply, thank you very much for the information.

Right now I'm looking at TTS MasterTune, Steve Cole has come up with the 2009 drive by wire calibrations. The winters are very long here so the bike won't be coming out until April/May, plenty of time for someone to come up with something..... I hope!

on the bearing thing, i bought my touring bike because the engine grenaded to say the least, all started with the inner bearing coming undone. passed metal through EVERYTHING!! died when a big enough chunk of metal exploded the oil pump.

Holy crap, I'll take that as a yes on the bearing swap subject then.

Don't scrimp...especially on the small stuff.

As far as what to include or not include, follow Scott's recommendations for what's needed in your build. A reputable builder won't recommend something just to add to the price tag.

Tuning devices: a key factor here is using the device that your tuner is comfortable with. But, early on for the 2009 bikes, tuning devices are limited until the rest of the after market catches up.

Inner cam bearings:
Caged needle bearings work well for low load/high speed.
Full complement needle bearings (B-168) work well for high load/low speed. 6000 crank RPM = 3000 cam RPM ie low speed in the bearing world.

I've emailed Scott and asked him the bearing question, I'll go with whatever he says.
As far as the tuner is concerned, I live in the middle of nowhere so I'll have to content myself with a canned map until I can get it properly tuned. However, the TTS V-Tune looks very interesting.

Crank

Yves,
Are taking the crank out?
I replaced the inner and outer bearings with Timken...As for tuning, there is shop in Mount Hope, Hamilton area, but only like to tune own engine builds....When you get it together maybe we can hookup for a road trip south for tuning..

Cheers

I wasn't planning on splitting the case, I'm going to measure my crank runout while I have the engine opened up. I asked Scott what kind of numbers were acceptable. I know it would probably be better to change the bearings but it's the first time I work on a Harley engine (I've done a lot of work on my Audi but not on the FatBoy) so I'm a little bit weary.
That "tuning trip" sounds like a good idea.

Your question makes me wonder about the 09 bottom end. Have there been any changes to the 09? You just might want to think about the timkin conversion.

I'm not sure, I checked the specifications for the runout (shaft measured in case) in my 2009 service manual and it's at 0.012. I just got back in the Harley thing after a few years out of it and found out about the crank problems on this forum.
I think SE and JIMS (probably the same) offer a Timkin conversion kit (plus tools for $800.00 if I remember well).
Has anyone on here ever done this on their own? I wonder if there are more special tools needed than what's in the kit.
Anyway I'll start by measuring my runout and go from there.
