Hello,
As you may [or may not know] HD came out with the 135". They're saying its just for 2021+ touring only. I call BS - it's a M8 engine. I'm thinking an aftermarket tune you'd be A-OK.
Anyhow - dunno if anyone has a warranty compliant 135, or a non compliant one..?
Winter isn't even here yet...

I haven't seen one yet, but I am interested to see what the aftermarket comes up with for the higher displacement kits.
Curious to know why the 21+ are the only ones that can get the 135. I know the ECm changed, perhaps that is why?

We installed the SE 135 in one of our shop bikes; 2022 Street Glide ST. We started developing Power Vision tunes last week with a few different exhausts, we will be opening the engine up and testing several different aftermarket cams, and we will then likely increase the compression and push it a bit further. H-D is not listing motor fitment for 17-20 models as they currently have 49 state certification for 21-later models.

Anybody seen a 135?
I did see a 135 in Texas 2 weeks ago. It was sitting in an engine stand on the parts counter and the guy said it was sold and waiting to be put in. I asked about the price, he said it was going to run about 10 grand + with labor.
After soiling my pants, I excused myself and moved smartly out.
