...or, sell the one you have and buy a new pair of better quality reproductions, that assemble with better tolerances than the Yamaha items ever did, for about 1/3rd the price!

Nic,

The late model genuine TZ rods are very likely to break, especially in a 350. Even in a 250, they were marginal. The old "278" Yamaha rods, which were in your crank, were the best genuine rods. Compare how much more material is around the big end on the new one to the old 278 rods!!!

There are the ProX rod kits in the spares kit. They have the 1mm wider big end bearing and conrod width to suit. At the little end, they take a 1mm larger diameter bearing. As discussed, these may need 0.5mm thrust washers to assemble the crank to the correct width, rather than the 1.0mm items. There is a kit that has the same dimensions as the standard rod kit, but it was suggested to me by Marcus DeCaux to use the beefier items.

The other rods that have a good reputation are the "Long" brand kits. In retrospect, these are what I would be using. Nobby sells them in Victoria through Hyside Trading. Well priced too.

Where did the 278 rods originate from? Were they a TZ part?

The reason I ask is that I hae an air cooled RD bottom end with 278 rods. It seems like an original bottom end. It would seem unnecessary to rebuild a street RD crank with TZ rods.

I PM'd you some info, Nic.

As I recall, the 278 rods are a stock Yamaha part, though they had an oiling slot in the big-end for the TZ. Alistair had a brand-new 750 crank that had been assembled by yamaha with RD rods (278)...

My vote is for 'Long' rods, with (I think) an RG500 big-end bearing.

If you do want a Yamaha 3G2 rod, there's one on ebay (the whole rod kit) (not mine)...
