2 years since I’ve messed with this thing. Getting married and buying/renovating a house will do that. Now that the state is on lockdown for 3 weeks I’ll have some time to work on it. Hopefully I’ll have it cruising around before lockdown is over, would be nice to cruise in when it warms up a little.

So one of the main issues is the chain hitting the engine mount and bike frame. I have another idler pulley so either moving the one to the bottom part of the frame or adding the second idler. Hopefully we can route it in a way that it’s not contacting anything. It’s close too so it’s a balancing act.

Also have to install the throttle and finish doing the brake line. So I’ll have to get those sorted. Also hooking up the fuel and electrics.

But first things first, got to find the box of parts and hope everything survived the move.

Well I found the box of parts! Everything appears to be relatively intact. Time to get started.

Moved the idler to the bottom section of the frame. I also trimmed the engine mount and had to file down the rear brake bracket screw. It is still pretty close to things but hopefully will be alright. I’m sure I’ll have to adjust it more.

Put the clutch back together and ran the cable. Thankfully I had a screw in my screw drawer that fit the clutch arm.

Harry is helping by inspecting the line.

Had to drill a hole in the handlebar for the throttle assembly. It came together pretty well.

The carb was a little tougher. This is the performance carb and operates a bit differently than the standard one, the throttle cable doesn’t interact with the needle/jet at all. Thankfully I looked up the instructions as you have to throw out the metal tube that the cable snakes thru or it won’t be long enough. Also you need to use pipe sealing tape to hold the remaining nut section in the carb assembly. If it falls out apparently your throttle can get stuck. Not great!

Wiring is pretty simple as expected. It doesn’t look great now but I’ll dress it up later on. Just want everything to function first.

Fuel system was easy. Just a tube. It was nice that they included a fuel shutoff valve.

That’s it! Just have to check the garage to see if I got enough gas and the right kind of oil to mix in. Hopefully will be driving this today!
