The laser sensors are quite handy, for example, I use one to quickly pick out an "off" cylinder on multi-cylinder engines. Jon Finally a light at the end of the tunnel. Thanks for the solution. I an converting the TY250 into the "enduro" model with thicker seat, lower Honda CR250 footpegs, headlight, horn, mirrors and taillight. I plan to to keep the oil injection and use it for trail riding and trips to the grocery store. It doesn't take much to make a bike street legal in Texas. Here our temperatures are often over 100 degrees F. My MX competition days are over with and I have fond memories of riding mountain trails on my old Bultaco Alpina 350. One of many bikes I should have kept. Thanks

I purchased a 85-702 Trail Tech Vector Computer, the version that fits bikes with drum brakes, for my 74 TY250. One of its many features is an engine temperature sensor that mounts under the spark plug. It has a warning light if the temperature gets too hot. As part of the installation you have to enter the normal engine temperature. Does anyone know what the normal operating temperature should be? Thanks,

Hi from Dallas Texas, Just purchased a great running 1974 TY250. 95% original except for rear fender, black frame?, aluminum handlebar, butchered wiring harness and a very nice fork brace that fits inside the fender. I plan to add the Headlight/Taillight/speedometer and have the fuel tank repainted. The tank had some internal rust but I filled the tank with salt and vinegar and after sitting 4 days the rust is gone. As a hobby I repair and restore old cars and motorcycles and I look forward to getting an education from the Forum.
