I've adjusted valves on different bikes before and have never had a problem until now. After doing some minor adjustments on a few valves, now it seems to ticking quite loud now.

It sounds like exhausts valves on the left side. I got the cover off and I am going to recheck them. I just hate the fact of having to tear it down again to check it again. Has anyone else ever had this problem?

Based on my experience and what I have read on this board (and others - shame on me

) that is a fairly common symptom. Especially if the ones you adjusted were on the tight side of spec. Aside from the hassle of pulling it all apart it's a good idea to double check things.

I should qualify "my experience" as doing a valve adjust once under a watchful eye but the valve train was slightly "noisier" after wards while being very rythmic... I would have panicked had we not triple checked everything before buttoning it back up.

I think I found my culprit. One of the hoses on the front left side of the motor didn't get reconnected. I was about 3/4 done taking the cover off when I noticed it. So just in case, I double checked my valves. They are exactly where they need to be. So I put it back together and started it. The ticking is gone and is running much smoother. The only thing left on the agenda is to sync the carbs, but that will be next week. My bike has already been done for 2 weeks waiting on parts. I want to ride this weekend.

I prefer to adjust the valves to the high end of the specs, with the intention that they won't close up as soon -- that 's the usual direction they take based on my observations.

When so adjusted the engine sounds like many mice typing away at high speed on tiny typewriters!

Just a thought.

I took it to work today and ran great. I definitely feel that the disconnected hose was the culprit. I also had another problem today, I was riding to work and got on it and around 6K rpm's, it stuttered some. Also this afternoon, it was leaking gas out of the hose at the petcock. I removed the bolts and raised the tank and figured out what happened. The vent hose got kinked between the tank and the airbox.

So that explains the leaking gas and the suttering problem. So after all that, on the ride home, the bike ran like a champ.

when i do work on my b4 i find myself always
kinking the lines to the tank and even setting the throttle cable
in the wrong place to where the bike would run funny.
i'd think why are the carbs acting funny when i turn my handlebars?

viva hinged tanks!
