I just put it back on. I had to put it next to the manifold with the insulating blocks forward of it--in other words the insulating blocks are toward the fender, away from the engine, and forward of the heat shield. It has much better fit and clearance that way. However, no matter which way it goes, those two little throttle springs that clip onto the bracket beneath the carbs rub against the bracket. No adjustment seems to fix that. I had the same issue the last time I played with it. Any ideas? Is there some trick to installing the springs with this setup?
