Frame failures around the headstock area were a common problem with the "F" model 350's, for this reason a large number of owners chose to ditch the stock frames and replace them with units made by such manufacturers as Nikko Bakker, Bimota, Spondon, Maxton, etc. Others chose to reinforce the stocker with additional bracing such as that shown in the photo. | Frame failures around the headstock area were a common problem with the "F" model 350's, for this reason a large number of owners chose to ditch the stock frames and replace them with units made by such manufacturers as Nikko Bakker, Bimota, Spondon, Maxton, etc. Others chose to reinforce the stocker with additional bracing such as that shown in the photo. | ||

1980's TZ350 G was virtually the same as the previous "F" apart from another attempt at improving the conrod, reverting back to the older "E" inner main bearing circlip/washers, a revised piston silicon content as well as strengthening in the sides of the piston, and a different "dipstick". Another change was the way the ignition rotor was bolted on to the crankshaft. The timing side crank wheel had an external thread and nut, where the earlier models had the standard 7mm internal thread. | |||
The 350 "G" was never really improved on, despite Yamaha releasing another model, the "H", which was really just a case of the factory using up a lot of it's stock of parts, giving up further production of the mighty TZ350 once the [[FIM]] dropped the 350cc World Championship class in 1982. | |||
