I'm probably going to remove the Andrews 30 T sprocket this winter and replace it with the Tri Glide sprocket, I should be used to doing everything twice by now.  I totally agree that the OEM belt is the best way to go.  I think Steve's persistence is a huge asset for those that have done the conversion or are thinking about it.  If I had a black swingarm I would go this route but I just don't see how this can be done on a CVO for $100.00 unless you don't have to paint the swingarm.  We can easily remove the material required but I don't think the gusset can be installed without having to paint the area.  Am I wrong here?

You are correct.  Welding is hell on paint!

The bald guy can still weld.

That is a pretty weld.

Good Job

I don't believe there's any issues with the Andrew's pulleys. I ran a 30T Andrews for over 10K on my 07 with an OEM Sportster belt.
I will be using an Andrews 31T on the 120R going in my 2012 SG. I had this particular 31T on three different bikes now. By the way, the 31T is doable with a stock
belt and a less invasive swingarm mod. A guy just needs to add a little material to the cam adjusters to push the axle to the end of the slot. Right now there is rear travel left,
the stock cams just don't use it all. Maybe a slight clearance at the end of the axle slot too. No repaint with this mod. I bet this little trick gets popular.

Good news to hear that the Andrews is not the issue, saves me allot of time as I'm slow and have to borrow all the tools to get the job done.  I'm using the Sportster belt (136T) you recommended and so far the belt looks like new with 6K on it.  So if I'm already using an OEM belt I don't see a reason to lengthen the slot in the swingarm.  Is this something you are doing or recomending to stay with the OEM belt sizes for various bikes?  Thanks for all the input Steve.

Your 08 is different from the 09s and later bikes. You have the option of a 1 tooth shorter, 136T OEM Sporty belt. The 09s and later bikes need a 139T belt
that is only available in the aftermarket. That's why we need a swingarm mod to run the OEM 140T.

I spent all day yesterday tearing apart my 2011 Ultra to put on a 30T pulley from the HD Trike and a 137T belt from a 2007 dresser. To my dismay it doesn't work.    Can't get the wheel forward enough to install the axle. I assumed since the wheel was almost all the way back in the adjustment slot that would be -1T to bring it to the front and 2 less teeth on the pulley it would all work. Soooo if anyone wants a new genuine HD  1" wide 137T belt cheap let me know. Sucks to be me today.

So on 08 se ultra I can change pulley and put on sportster belt? No worries

Keep in mind that you'll be using a belt whose application and design specs were for a bike that weighs about 550 pounds and has 60-65 horsepower.  You'll then be that putting in a bike that weighs a ton and will likely double the torque of the original application.

You had the right idea Dave. You went -3 teeth on the belt. The stock 2011 belt is 140T.

Yeah I know stock is 140T. I figured the 2 less teeth on the pulley and the slot distance would allow for the 3rd tooth. As Maxwell Smart says " I missed it by thaaat much"!

I quess I misunderstood your first post. I'm not real good with Celsius conversion as a few know.

Yes! No issues with the Sportster belt on a 100 HP bagger. I did this a hundred times with my Sportster belted 07.

Awesome! Looks like I do have a winter project. Now I gotta find part numbers
