I have delayed second gear engage problem pretty sure it is worn dogs. Want to confirm which gears to replace. By looking at the manual looks like second gear is engaged are the 3 and 2 gears on the counter shaft ?

I believe the issue is gears 1-2, not 2-3.

Take it apart and be sure which gear has broken dogs. Avoid driving it with bits of broken dog floating about in the fluid.

It's not that hard. Just remove the drive sprocket, take the primary cover off, remove the primary chain and its sprockets (left hand thread in the clutch basket), then it's four bolts and a tiny crowbar to remove the trap door. I would replace both double-dog sliding gears if both show wear.

You don't even have to remove the drive sprocket(I assume you're referring to the front pulley to the final drive on the right side of the bike? I don't actually know what it's called). You can pull off the primary cover, clutch/rotor, and the whole transmission will come out with the right side pulley and belt still on the bike.

Also keep in mind it takes very minimal wear for these kind of problems. Mine sometimes has a similar problem going from 2nd to 3rd gear, only if I'm lazy with my shifts. When I pulled the transmission out, it's just the slightest bit of rounding on the corners, and honestly if I didn't already know it was doing that, I never would've imagined that little amount of wear could be felt. Someday I'll replace them, but I had enough stuff I was working on this past winter. It was very simple to get the transmission out, although there was a handful of steps before to get you there, nothing to be afraid of under that cover.

The last time I did a transmission pull, my drive sprocket had removed itself in traffic.

If you decide to take the transmission out and do this work, do yourself a favor and buy a handful of the stock 0.07" transmission thrust washers (shims). Take them to a local machinist and ask to have them surface ground to 0.03" and also some at 0.04". These transmissions are put together with the same 0.07" thrust washers no matter the tolerances in the gears. What you end up with are transmissions that are sloppy and some that are tight.

When I did my rebuild I corrected any areas where there was excessive play in the shifting of the transmission and when I put everything back together it shifted so damn nice it felt like a new Baker tranny or something. It was fantastic.

I may even have some 0.03" or 0.04" shims still kicking around somewhere. If not, they are available at any Harley dealership as they are identical to the ones in the Sportster.

Actually....I just found this post I made at the XL Forum about this that explains it better in more detail.
