Hi:

There are many of us who received there 55AX over the weekend. Major question, what's the deal with the wording of ads saying 90 degree muffler adapter. We are all looking for adapter like the 1.20AX. Many on RCU want to know what's up (adapters-no need for expensive aftermarket mufflers). Missing part or goof in advertising? For the price it should be there. I'm not angry, just puzzled. BTW had .55 on test stand yesterday to break in. WOW fantastic engine. I have 2 of them.

FromTower ad AND other dealers!!

the cylinder and makes the plating more durable. Also, the plating
process is more consistent, resulting in a more precise fit between
piston and sleeve for better compression and longer life.
