Nice work! I’m in SA TX glad to see this stuff nearby!

Rings should be installed from the top of the cylinder to check gap not the bottom.

[@d-railfpv9315]

[@chrismason9217]

Beautiful bike 👍🏼

[@michaelmitchell5909]

Thats amazing. Makes the 95 kit in this 04 rk i got used seem like a stock motor

[@leonardstanford1877]

My favorite TC engine is the 95 inch !

[@chancehunter3098]

what did you end up setting the timing and slope for out of curiosity?

[@michaelmoser2200]

That doesnt look like a Mik Carb looks like the Harley one, good tech video

[@sambrandon6770]

Mr103 cams? That intake closing # doesnt spund right for that cam.

[@hybridEP3]

How much did all the parts run?

[@Sway1177]

On twin cams what's your experience with when the cam chain tensioners tend to fail or should be replaced.

What are the initial timing and advance slope at on this build? I have almost a similar setup but i get pinging when i pull throttle from lower rpm. My initial timing is at 5 and my advance is at 6. Althought my cams are 583 cams from sscycle. Should i be retarding my initial timing?

Nice job editing the video. Good information. Good parts. Well done. Thank you!......I do have a question about the bag mounts that were on that bike. Not even 3 days ago I was looking for the mounting hardware for those style of bags. I have a pair and would like to mount them to my Dyna. Do you know where to get the mounting kit or can you share a pic of how you had those mounted? I appreciate the help and again, good video!

[@vroomvideo9271]

Is it just me or did they give that bike back to the customer way to lean in AFR above 4k rpm…..

[@michaelmitchell5909]

I have a 2004 road king i bought used with a 95" kit on it with 525 cams. Whats the chance my crank runout is as good as what that one was???. Id love to do sns gear drive cams...
