the belt is covered well enough that significant water entry isn't likely, and even if a little water did seep in, there's enough tension on the belt that nothing is going to skip. Was what you did any different than riding in the rain?

Honda makes one of the most reliable motorcycles made. Others are reliable too, like Yamaha , but OEM Honda parts are a lot less, and it's a heck of a lot easier to check & adjust the valve clearances on both the ST1100, ST1300 than a FJR, Kawasaki, or Triumph Trophy." BTW, The way Honda makes you pull the cam covers to replace the belt is another stupid bit of engineering. I have replaced a LOT of car timing belts and EVERY ONE of them had the timing marks on the cam sprocket. STIPID. "
BTW Herb, So does the ST1100. There are timing marks on the crank pulley and both camshaft sprockets.
I doubt that I will ever buy another Honda.
I suggest studying the w/shop manual first... no need to pull the valve covers there...The way Honda makes you pull the cam covers to replace the belt is another stupid bit of engineering.
I have the Honda shop manual and it shows the timing marks ON THE CAMS, not on the sprockets. It also shows pulling the cam covers to access the timing marks.I suggest studying the w/shop manual first... no need to pull the valve covers there...
Dunno, always worked after page 8-13 showing the marks on the pulleys...I have the Honda shop manual and it shows the timing marks ON THE CAMS, not on the sprockets.
See what can happen without a guide plate on the RHS pulley .........Dunno, always worked after page 8-13 showing the marks on the pulleys...
But on a bike with unknown history it seems a safe procedure to also check proper cam setting anyway...
My ST-mech was once confronted with an ST which must have been moonshine serviced, idle like a bag of cloth-pins, hesitant in accepting throttle, etc...
Long STory short:
belt was off 2 notches on the RHS pulley, plus both cams badly off their markings on the reduction gear (apparently in an attempt to "correct" the fault during installation of the t/belt...)
Interesting to know, gonna have to try it.I found that you can check whether the slides are working by blowing air into the diaphragm air vents, which are the large bore plastic T piece between the carbs. If you leave the rubber hoses attached to the vents you can just use your mouth and blow. You will need the carbs off the bike for this as you have to be looking back up the throttle bore with the throttle plates open (unless you can bend the rubber trumpet far enough to see straight in). Because each air vent connects to a pair of carbs, you can visually see if they are moving together or not.

For jim van, I can't get to the 2 bottom screws on the slide covers with the carbs on the bike, the frame rails cover them. Since I will have the carbs off to check this out I will see what I can find out. Sorry about that !! It's been awhile, but I thought I had mine off with the carbs installed in the bike.
Although when I was cleaning the carbs I had the slides out and didn't find any problems with the slides or diaphrams.
Trying to figure out what those hoses are for. My other bikes, and many others I have worked on, have vacuum carbs and don't have that kind of setup.
Has anyone tried to run these without the air horns on? What happens if I run it without the air horns?
This thing couldn't get much worse on the midrange, and still run. If I run without the air horns and the air filter I would be able to see if the slides are opening. Or would they not open because the air horns are not on it?
It will detract big time from your mid-range power. They literally "tune" the intake.
That's pretty well done in the Honda Common Service Manual, Herb. I got mine years ago and it's been a very valuable resource for me. IINM, there is (was?) a downloadable digital version (PDF?) some where out there in the ether.I really wish that the Honda manual had done a better job of explaining the principles of operation of these systems.
