    Looks like a great ride!!

    I can say that mine will probably never get to the 'done' status.......... If it's not one thing, it's another!

    Thanks, guys. Tony, have a 79 predator on another bike and you're right it hauls arse with single speed and Hilliard clutch. I like my 3-speed hub, though, never had a problem but I don't abuse it - no need. This setup is much faster than the 47 HS that sounded like a lawn mower. I grew up with 2-smokers, so that's what I like. 4 strokes are easier and more reliable, but I like the smell of FAST. How can you tell which version of a Predator you have? I don't know what you mean by a Hemi. Guessing you mean a domed piston. We have strayed dangerous close to motorcycles with these builds, but that's OK with me. (guess that is progress, Dan) I started with a rag mount sprocket, coaster brake only, and no electrics. I like where I am now much better. This bike will smoke my 50cc Sachs 3-speed and my wife's Yamaha Vino. Haven't clocked top speed yet, but that's coming soon. Might mount a Biggs muffler in pipe, it rattles my neighbors' windows, but when it kicks in, I'm gone!

    Always wanted to be a matchmaker, Dan. When are you starting her bike? It should be good for more than a few free drinks!

    And she is from a part of Russia I had visited way back. Well only 12 hrs away. By Russian standards, the next county over, LoL.

    We are still partners and think I love her more now than ever. We still live in the same house and all and are looking at condos together. She really is the best Human I have ever met. The Shelly thing is really getting to her. She agreed with you and the meds worked. Dawg is 100% better. Still 14 yrs old but back to herself, as best as can be expected.

    Racing pipe is great for squeezing power from engine, but nearly blows everyone's eardrums. Decided to tame a little with an add-on muffler lie the one on my Sachs, so I measured the inside of the exhau DSCN3480.JPG DSCN3481.JPG DSCN3482.JPG st and went to work. Here's what came of it from a $4 Briggs mower muffler.

    The Briggs muffler also worked great on mine. Just the right amount of 'attitude' without getting attitude from the neighbors.

    Did you punch out the baffle in it? Lot of flow to be gained.

    Personally for me, it already had plenty of flow --- needed more of the noise reduction. This is the best exhaust that I've ran on my bike.

    Pipe works with the Briggs. Soldered the seam to make sure there's no leak. Took ride through empty fields, this is gonna be my dirt MB. Crappy bike centerstand couldn't take kickstarts' so I threw on a HD Whizzer stand. Need to reinstall pullstart, but the pipe's in the way. Trying to come up with a retrofit.
