Ty175 Electronic Ignition?

[kevin j]

I have several 1975+- TY175. One is a fun original vintage bike. One is a beatup (but top shape mechanically with 250 tubes, wide pegs etc) buddy bike to teach kids to ride on.

This one suddenly died and lost spark. This has been a recurring problem with all of mine. Stators seems susceptible to heat problems. Is this common?

SO, before I start chasing the gremlins again, I'd like to consider changing to solid state ignition. I know B&J has a kit but its pretty expensive for the value of these bikes. Are there any later Yamaha solid state ignitions that will bolt in with minor modifications only? (i.e dremel tool, not NC machining)

I am interested in low end, smooth power, and long term reliability. Don't need quick or high end power at all for the riders this bike is used with.

Also looking for some better shocks, but can't rationalize the Falcons costs.

BTW: I did find carb parts are almost unavailable, but the DT100 carb is the same body size with controls on the correct side. Floats and needle/seat interchange, but jetting & slide must be moved back & forth. I have purchased several on ebay cheap enough for spares, but do need more jets and slides. Anyone know of good sources?
