Sportsman Flyer Build

This started here, (The trigger is pulled, 79cc Predator and purchased 5/21/16 Sportsman Flyer loop frame).
But that was before I made the commitment to build one right.
So far:
Sportsman Flyer Drop Loop frame (Black).
79cc predator engine. Governor removed.
Sportsman Flyer fuel tank, got tank graphics also.
Sportsman Flyer tool box.
Mikuni 19mm carb.
Sportsman Flyer intake manifold and my custom exhaust manifold to accept 1" I.D. SS flex tubing.
Sportsman Flyer approved Felt springer fork.
26" front wheel with Sturmey Archer drum brake. " Not Sportsman Flyer supplied "
Flyers use a Worksman front drum brake wheel.
26" Worksman 4136Rear wheel Shimano 110 helps keep drive train geometry.
Tried to use a Q-matic transmission. Not drop loop friendly. So now the Sportsman Flyer approved Bully clutch is on the engine. $245 it better be good.
Sportsman Flyer Reduction Drive is on back order. It is the set of components that will let this build start to flesh out.
Wald steel fenders.
Wald 867 handle bars.
Schwalbe Fat Franks crème color.
Sportsman Flyer 44t sprocket and adapter ( mounted to Worksman wheel 2/7/17 )
To do the build I have built a bike stand that mounts to the chain stays @ 36" high. just like the one I worked with at a Schwinn Shop in the late 60's and early 70's
( The bike stand is performing flawlessly .)
(Changed my mind when I started to estimate hours to reverse engineer the engine mount system that Pat Dolan already perfected?)
I purchased Sportsman Flyers engine mount system, and wondered why I would ruin a Flyer build ?
Pilgrims, don't mess with a proven design. I won't.

Just did a update on my last post. Most of the challenges so far are self inflicted.
 
Ditto the above, still waiting for back ordered Reduction System from Sportsman Flyer. In the mean time I started another thread (bad me) dealing with how to successfully attach a fender to a Sunlite springer fork.

Anyone thinking of a high quality kit or prebuilt motorized bicycle seek no further. Sportsman Flyer is what you want unless you are drawn to Whizzers. I went at my Sportsman Flyer 80 build the very hardest way a person can and my progress shows it. Pat Dolan is the real deal. Glad he is so kind to help me in this build. And I can see the light at the end of the tunnel. Fired up the furnace in my machine shop to a working temp of 65F. Niggely details.

Show us da bike.:) show us da bike.
 
gary55, CrazyDan,
New computer with Win10 and I have done myself again. Win10 came with McAfee and photos uploaded well.
I got it in my head to use Norton instead. To do so had to delete McAfee. Now photos will not load to a savable file.
Got to get the IT guy over here to fix my screw-up.
Made one discovery Friday 11/17/17, coaster brake arm not offset enough. Explains chain alignment trouble.
Purchased new coaster brake arm and am going to send it to Pat Dolan for correct offset bends.
I am a good example of what happens when you don't order a complete kit from Sportsman Flyer.
Time lost? One year easy. I should have been riding this last May.

Pat Dolan was right about swinging the engine mount sidewise to achieve alignment of the Bully sprocket to the reduction input sprocket. The chain now feeds without trying to jump. .
I still had the brake arm locked and couldn’t shift the drive sprocket to align with the reduction output. In February I finally got of my ass to analyze what I was doing wrong. First thing was to unclamp the brake arm and things started looking better. Look closely and you will see that with wrong offset the brake arm doesn't give anywhere near the clearance needed to allow the SPORTSMAN HEAVY DUTY SPROCKET ADAPTER to shift into alignment with the reduction drive. Much better. The brake arm offset is 3/4". The way I figured it out was to go back in Pat's Flicker account and delve through his SF80 build photos which he annotated. Lucky me.

Another delay, this is what happens when you don't purchase a complete Motoredbike.
Long time ago I made a decision to run gold chain on pedal side of my bike. Went to the local bike/ski shop in
Hartford, WI. and purchased a pack of KMC Z410 gold. Fast forward last weekend after getting engine side chains set.
Round to pedal side and hang the chain and the chain is a half link from being right and to my knowledge that style chain doesn't have half links.
Back in the house sipping on some barley pop, snooping the internet me thinks I have found the Holy Grail of half link chain. Shadow Conspiracy Interlock V2 Half Link. Didn't pay attention to primary use too much (Barley Pop) that it's recommended use was Fixies and BMX. Their bicycles right? Gotta be good.
InterlockV2 arrived 4/13/18? I ain't going there. So today 4/14 I am set to fit the chain on my bike and the darn chain is short by about two inches. *^$#&@ ! So back to the house pour a New Belgium White Ale. You catching on as to why this build is taking longer than expected? Oh well.
Any way in the package of V2 chain was a nice B\W double side instruction sheet recommending their Shadow Conspiracy Interlock Chain Breaker. Fact is I Raleigh tool kit braker broke and the cheapy from Wally World is.
So 4/13/18 I order one knowing most of a week will pass before it arrives.
Then today 4/14 I had to order another V2 chain.
That's my story, for lack of 3" of chain I spent another $35 to have the prettiest pedal chain a Sportsman Flyer ever had.
