Ck dia. for me.

There's a difference in sizes? I wasn't aware....I know some carbs are offset to the left,and some are centered,according to model/year,but I didn't know the sizes were different.
Are you talking diameter/threads?.....help me!

Hi DR, I just measured the inside thread diameter on my 91 head and it measures about .400". I'd guess at the outside diameter threads on the pipe to be 11mm, that would be about a .030" thread heighth........Shoo

Not so sure....maybe in my case only Earl.

I just got a motor in and its had some HeliArc work done on it. May be a whole different fitting welded on for all I know. Also recieved some pipes I bought that were listed as 91 and they dont fit. Couldve been the seller, might be the motor....dunno. Have to check my others today to see where Im at on it, just havent had time this week;)


Shoo....will check it out today.

Your right. Its in the neighborhood of .430

My junk motor has a pipe and bushing in the .460 range:rolleyes: Dont know why.

This NIP pipe and muffler are for a OS 61 to 90 motor. I double checked. Its in the
.430 range so its right.

Lemme know if your interested. Id still like one of those fine hammers:D

Hey Dad_Roman, Yes sir, I am interested. I don't have any Shooboy Hammers at this time as I decided to close down for the Summer. I had 63 Hammers made and thought they would last a little while, they all sold in about 3 weeks. I could owe you a Hammer and get one of the first one's to you when I resume production in September, or just let me know what you're looking to get. Thanks as always, Shoo
