Broken cam belt?

Postby ripsaw » Fri Jun 07, 2013 10:06 am



Mt 1986 Aspy fired up 1st time last Saturday, then cut out. I tried starting again and it failed to do so , but was making a fairly loud "clicking" sound coming from the right hand side of the engine. I am wondering if this could be a snapped cam-belt symptom. If it is, what sort of damage will that do? Is it worth looking at it or is it new engine time? Can anyone help me out with this.

I would suggest you take the timing belt covers off and check the belts,also check the timing marks and the t1 mark to see if they are off. If you broke a belt it will damage your valves and even put holes through the pistons (not a good thing). Pull your plugs and check them,the clicking could be anything but you will need to find where it is coming from first. After you get the timing belt covers off,if the belts are still there pull the plugs and turn the motor over by hand not with the starter listen for any signs the the pistons hitting the valves you should not feel any hard resistance while turning the motor by hand. Hopefully the belts and motor are ok,and no damage done. Keep us posted on what you find and Im sure others will have more insight to what may be going on. And I just reread your post the clicking could be coming from your fuel pump,and you may just want to check that your fuel pump has not bit the dust.-----------------Hal

I stripped it down over the weekend and was pleasantly surprised to see both belt in tact. I will check the crank movement and post an update soon. Where is the fuel pump located?

Your fuel pump will be on the right side of your bike,just above the oil cap. Looks like a round soup can and about the same size,and they do click when running. If it is really loud clicking your pump may be bad and not pumping any fuel. Take the hose going to the carbs off and put in a bucket start the bike up you should be getting fuel pumped out in to the bucket. If not there is a cheaper fix then oem pump. I think it is a fuel pump from a Honda prelude,you can do a search here on the site for the model and how to install it. Good Luck-----------------------------Hal

Some of the fuel pumps on the 1200 still function while making a loud clicking sound. This is the result of a worn rubber bushing inside the pump itself. If you fuel pump puts fuel into the bucket but still makes this racket, the bushing is your culprit. It involves a little work but very little cost to fix this particular issue. "How to" can be found for this process.

The other possibility for clicking sound would be the valves. The 1200 uses hydrolic valve lash adjusters. Occasionally, some trash, or gunk in the oil, or oil that is too thick can clog up the oil galley in the heads and not allow sufficient oil pressure for the lash adjusters to work properly, and the valves start ticking. Usually, a good motor flush or two will help eliminate this problem. Good luck.
