Hey guys, thought I would make my own build thread, so I can more easily track answers to questions I may have. (Being a newbie).
Ok... The build..
New handle bars, longer brake cable, and OCC handlebar bag we're the first thing . While waiting on engine kit.

Engine kit arrived, so... On it went.

Stock pipe for now...
I used the provided chain tensioner, but made a spring loaded set up out of the 2 pieces. Using the holes already in the rear axle dropouts. The smaller bracket went on the top hole and is a spring holder.

Ended up adding a second spring.. smaller spring to the bolt I used on the upper guide pully.. not a tensioner really, just a chain guide for that long stretch of chain.

You can see that pully here better.

Gas tank is mounted with the brackets screwed to top of bar upside down.. no pics of that. But here's the tank, keeping with the OCC theme.

Added front brakes..from an old donor bike.

Thru bolted, and used the 1/4 round part in a couple of mounting brackets, to reinforce, and disperse the pressure of the thru bolts on the forks. They hug the forks pretty good.
Well everything seems to be working as it should, I guess... Goes well, and stops well.
Thanks for stopping by..

2 spark plugs dead today...barely look even slightly used. But won't spark. As tho something died inside plug's post..can the resister inside a plug burn up, snap, or otherwise fail?
NGK CR7HSA plugs on a Huasheng 49cc 4 stroke.

I've never had any issues with my 49cc or 53cc huashengs producing spark. It might be your kill switch. Disconnect the kill switch and keep the wire as far from the frame as possible and determine if its not the engine shorting out.

I wonder if a Subaru would fit in that frame the 7hp that would be a cool bike: if Subaru made a motorcycle lol. If the plugs getting messed up probably a short check coil and killswitch like he said. Maybe you can check it with a meter (electrical not my specialty).

My magneto is rusted like a mofo and it's still running like a champ. If you have a spark problem it is either a shorted out killswitch, magneto to flywheel gap or spark plug gap... Unless your spark plug wire melted to your exhaust.
