Hi, if you race a Z1 then use a Z1 swingarm in your H2 Frame. The 500 engine will fit in if you wish to use that. I would offer a completely different opinion to JA re the shorter swingarm. If you try it(short one) on some fast corners you will greet Jesus waving to you from the sand trap. Have a chat to Terry Waite NZ historic racer (H1& H2) or Kevin Mc Donald from Rogers Yamaha in Invercargill. They are good guys and love their triples. Oh, just reread the post and you have a B frame.The Z arm will be about 3/4 " shorter. Try a GS1000 swingarm, which is a "wee bit" wider at the front but can go in easy and pretty much the same length as your B arm.
