I recently got a stock muffler of of my brothers retired Street Bob, part # 64895-09. For the most part it looks similar to what everyone is using, but it does not taper at the end like all the pics I have seen here.

It does have the 'rail mount' and looking in the back of it, it is not straight through, it does have some baffling.

I am sure I will find out once the riding season is over and I tear into it, but I was wondering if anyone had exp. with one of these.

Also, I have been reading up on jetting combos, but if anyone wants to chime in with a recommendation here for this muffler, a K&N panel filter in the stock box at about sea level I am all ears!

Thank you,

Jac

Can't see the rail... I assume it's there...  It looks like it should mount up...
(you can mount up anything with enough fiddlin')... just do it...

I'd start with a #152.5 main... (do the 2/3 spacer mod, if you like... not critical)... then see how it runs...
If you need to turn out the idle mix more than 3 turns,... step up one on the pilot...

Making one jet change at a time,.. let's you observe the results better...
Replace the float bowl screws with allen heads, and you can change jets with the carb on the bike in 5 minutes...
Read my muffler guide in the Tech section for tips on install...
Read my tuning guide for info on jetting...
Good luck... ...

Thanks guys! I am pretty sure that I run a little lean in the stock congif, so I know at least one step up in in order.

Serowbot, your carb tuning page has been up in my browser for a few weeks. I keep reading it, I think some of it will 'click' once I actually tear into the job.

Love the idea on the Allen Heads for the fuel bowl, do you have specs on what I am looking for at the store? I try to have have as much on hand BEFORE I tear things apart as possible!
