weatherstripping airbox cover

[davidduarte]

finally got a chance to weatherstrip my airbox cover. Stopped at Home Despot and got some weatherstripping:



Here's the airbox cover after I cleaned all the 30 year old gunk out:





and here's the finished product:

Looks good
Should last for another 30+ years...

I went and tightened up the airbox and intake boots too, just to be sure they were as tight as possible. We'll see tomorrow night when I start it up if it makes any difference. The bike only seems to want to idle when it's warm. I can start it with the choke but after a short time I have to turn the choke down otherwise it revs up to 4000. It's still much better than it was pre-carb cleaning and replacing intake and airbox boots.

Interested in how that goes for you. I know I need to do the weatherstripping on my air box. Mine runs fine, idles at 1200 but when I take it out and stop at a light sometimes it drops down to about 8 and dies on me.

I think that's pretty normal. The "choke" on these carbs is not a choke at all but a "fuel enrichment circuit". When it is on the carbs allow an enriched fuel and air mixture in. I have to do the same (not that my bike is without idle issues), as does my friend with his Mikuni BS-equipped Yamaha Radian. Doesn't take long for the revs to shoot up.
