When converting an M8 to a timken, do you need to use the same smaller crank spacer that you do with the TC? My compensator is too far out and I cant see any other reason this would happen.
The stock spacer cannot be used with a timken bearing conversion. You can machine the stock one shorter, or buy one from Darkhorse.
Perfect timing on asking about Timken on M8's. Trying to find out if the process is the same on an M8 as it is on the TC. Videos I'm seeing tell me it is and set the clearance the same. All for the future, warranty still in effect on my 2020 RGL with 131. Beefing up the bottom end after spending coin on the kit is counter productive but thinking Darkhorse for a better crank setup. Not sure if the stock 131 pistons will work, hope so but by the time I get to that point they might be worn out anyway. Thanks.
I suggest asking GRC before diving into the conversion. They advise against it and have solid actual real world experience with failures.
:up: Thanks.

Care to elaborate? Also, who is CRG?

They have had case failures and now fill the cases with epoxy if a timken has been installed. Not a recomendation or advice just what I have observed.

Where are they filling with epoxy?
I was wrong, my builder did not install a timken...For the exact reason HDSP mentioned. :kick:
Next thing that gets done I am not much of a fan of is balancer removal. There is a time and place but not for modest powered street bikes. I could be brought around if someone has some great reports of success.

I agree. Only for crazy turbo and scenarios where the engine never sees any mercy. Then I go with welding, plugging, dynamic balancing, no balancer.
And that means minus 2 for the softails
Are there two different M8 motors between touring and Softail? I thought since the M8 has a balancer it would be enough for one between the two models.

As above, Softails have 2.
Thank you for that info.
Lots of shops do the Timken conversion, if your got crank out why not ?

As was already stated, they can potentially cause case failures. My ( well known/respected ) builder confirmed this to me. Not that HDSP
isn't well known or respected, just stating that his opinion was confirmed.
Are the M8 baggers rubber mounted in addition to the internal balancer?
Deye-yes, but front is similiar to two swingarm bushing/isolators, not like the twin cam front
My 2011 RGU has a front mount cross bar with 2 isolation donuts instead of the single mount of the early version.
Yep, they started the double front mount on touring bikes in 2009.
yeah, sorry, I was stuck on early 08 type TC
08 was when the top mount was move to in front of the front head.
We're speaking about the front lower mount. 2009 they went to duel donut front lower mounts with the new frame.
Two of 16207-09 mounts.

I know what mounts your talking about, the change was done in two years top 08 bottom 09. Some assume it was done it one year. 08 is basically one year bike. Didn't mean to mess you up.
I'm not messed up. I own a 2008 and a 2009, I know what has what.
I just never looked at a late model bagger, my 2015 was the last bagger I had. I guess I should take one for a test ride. After the new softail I never looked back.

:up: and it's all in the Technical Forums as well
Can the M8 LHS be strengthened to support the Timken conversion or not worth the effort ?
Has anyone seen the stock left side roller fail?

I'm confused with this. Does the M8 Softail have 2 internal engine balancers or are you referring to one internal balancer plus external isolators? The TC B motor for the Softail has 2 internal balancers, got that part since I have a 2007 FXSTC. Just kinda sounded like you're saying the M8 has 2 internal balancers. Maybe I just need more sleep.

Yes, the M8 Softails have 2 internal gear driven balancers. Unlike the Twincam with 2 chain driven balancers.
The M8 touring have 1 internal gear driven balancer.
Add in: The Softails still are a rigid mounted powertrain.
Thanks for the reply. I'm curious about how this works but not finding any links or videos on it. Is there a specific name they've called this dual counter balancer for a better search? Video link?
Technical Forums are a good place to start

The beginning of the video shows the counter balance in action.
There are two, they are identical just timed different.
