air-box...

Postby idflyit » Sat Dec 27, 2014 12:22 pm



in an attempt to find a suspected vacuume leak..i have removed all the body work..taken the top off of the air-box,removed air-filter.that is a very complicatied looking box..what should I look out for while removing the bottom of the air-cleaner box.. the reason I think it has a vacuume leak is the idle has a 250 -300 rpm surge....& the cruise control has stopped working... THX TO ALL IN ADVANCE...HAPPY HOLIDAYS

I suspect the vacuum leak won't be at the top of the carbs/airbox. It'll be under the carbs. The most frequent culprit it the right-angled hose, beneath the carbs & under the rubber 'mat'.

This is the little #%^@#*&(% most commonly responsible for the idle surge.

Before you go ripping things apart, did you check the simple things 1st?

If 1 of your cruise control cancel switches is shot, or your speedometer cable is broken, they will cause the CC to not function.
Did you try adjusting the idle speed control knob back and forth a few times (?), as this often cures minor idle speed fluctuations

I did try the idle adj. knob..ran it up to 2500 then down to a very low 500rpm...repeated that for 10 minutes,while the bike was on the center stand..I didn't ride it.I did check the cruise cancel switch on the front brake lever..2 clicks is what I heard,while slowly squeezing the brake lever..DOES THE REAR BRAKE PEDAL have the same type of switch????..I have checked for vacuume leaks every where,that can be seen,but under the air-box..

That one switch does double duty. It both lights up the brake light and disengages the cruise control.

There is a double adjustment jam nut in behind a couple of exhaust shrouds below the battery box, rearward of the brake light switch and fore of the rear brake MC. Tough to get at clearly/properly to adjust.
