Rock and a hard place time. valve cover just catches the frame crossmember.
sprockets out of alignment (knew that because of yerf being non-reverse output shaft)
exhaust is really close to the shock in the stock location, which also puts the shock really close to the tire. exhaust blocks a move of the shock mount to where i hoped to put it.
Sooooooo
I can cut the frame out and rebrace it for clearance. Not a real big deal--pic below.
i can make or find a sprocket spacer ...bit of a pain deal
I can figure out if this is a 250 muffler and use the smaller muffler that came with the other engine.
OR,
I can move the engine mounts back about 2 inches and over about 1/2 and resolve all three of the above in one shot.
Anyone see any issues balance-wise with moving the engine back that much? longer chain. It's a bit tricky in that if i don't go back far enough, i wont be able to get at the spark plug because of interference with the upper frame rail--at the rear the reverse cable's metal neck limits how far back i can go before it hits the frame rail.
