First you will need to remove the seat and fuel tank.
Remove the chrome air filter cover and the filter to gain access to the 3 Phillips screws and 10mm bolt. Remove idle speed adjuster and 2 hoses from rear of the air box then pull it off. Note the tab on the top of the airbox and the slot on the frame for it.
The air inlet on top of the rear cylinder. Loosen the clamp and pull the hose off, then remove the 8mm bolts from the reed cover and remove the cover.
Cover removed, you can see the reed holder exposed here. Remove the reed holder.
Drill out the 2 screws, remove the reed/holder assembly and reinstall.

Reinsert the reed holder minus the reed and it's retainer and put the Coaster on, reinstall the two 8mm bolts.
This is the air inlet for the front cylinder, use the same process as on the rear cylinder.

Another view of the rear cylinder with the Coaster installed, note the missing air hose, which is covered next.
This bracket on top of the frame's backbone holds the vacuum pump that engages the system. Remove the 10mm bolt and pull off the pump. I also removed all the hoses attached to this pump.

I used a rubber cap to cover the open air hole on the back of the airbox.
