It looks similar to the STD, but the slightly sharp edges get in the way, so the same mounting won’t work. If I raise it to avoid contact, it hits the tank.
There’s no good mounting position to extend it all the way to the tail cowl area either, so I’ll keep it as short as possible.

Here’s what the digital tachometer shows at idle. I think it’ll be a bit higher on the road.

It’s been a while since I’ve seen the carburetors this rough—the engine’s running poorly too.
