Hey guys. Just got my $250 1985 honda 250sx last weekend.. seat and front mudflap were n.f.g. replaced mudflap and having the seat uphostered.. put a new plug in and kicked it and she fired! Went for a rip. She smokes. But runs good.. did a little clean up and painted some rust... put a battery from my yamaha in it and got no life no lights or anything...if i jump the solenoid it starts... does that mean my solenoid is bad or my switch on the handlebars?? Gonna dig into it more when i have more time.. ive got the manual and the wiring diagram.. any advice is appreciated!!!!!..trikes gonna be a sweet rider... tail light is there and put a new bulb in it... might keep it.. might go l.e.d.... shes got some bad cracks in the front tire its gonna need replacing. Recomendations???...
