mikuni boost connection

Recommended Posts

What is that connected to the boost pipe on my Mikuni carb ? Some type of booster is guess. What is it actually doing ? It's up the front near the exhaust outlet.

We are going to need a picture to know for sure what you are talking about. You are probably referring to the exhaust air injection system. US/Canadian models do not have it.

Yep, PAIR valve (pulsed air injection) air is injected into the exhaust to clean up emissions. Causes no performance loss, but the air going into the exhaust will cause mad popping if you put an aftermarket can on it. Evidently this popping goes on all the time, but the stock muffler, well it muffles it :thumbsup:
