Engine Clicking / Ticking?

Greetings all,

Still very new to this engine stuff. I heard a worrying noise yesterday, and not sure if it is something that I should be concerned about.
The noise is a very distinct clicking/ticking noise when the bike is idling, yet is inconsistent, and does not seem to be very apparent after the bike has been moving a little - I got my phone out and recorded the bike hopefully you can hear the noise that I am talking about - and perhaps identify it for me.

Hope this youtube embedding thing works and is legal within the forums.

This is a 87 750 - 35000 miles. I have had it for 500 miles, and other than coolant, oil, and plugs, have not done anything.

Thanks
Andrew

Probably ACCTs acting up. Do a search for Grambo Trick or look for it in the Vulcan Verses. Replace the worn springs, which is a short term solution, or go with MCCTs, which is pretty much permanent.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

www.tocmanufacturing for springs or mcct's, about 50 bucks each or follow the link in my sig line and build your own for about 6 bucks each. no matter which way you go its a quick and easy procedure just be sure if you replace the springs not to overtighten the cap nut on the acct!

it is the ACCTs for sure... springs are a temporary fix, the MCCTs from TOC are a 100% guarantee that the noise never comes back again.

Hey all,
thank you for replying -
Looking at Wib's mcct link you have a parts list, You mention 1 of each of the parts - but further down somebody said they did the front and rear. Does this mean that there are 2 of these things that I gotta do? Also Wib, did you every get your process on video? I am a very cautious mechanic - Not even sure I could call myself that. If there is the process on video, I can understand that.

Thanks
Andrew

So I think I answered the 2 of these question - I just found 2 on my bike - 1 hiding by the coolant bottle, and the other on the other side.
I will buy some parts tomorrow - and try not to break anything

Another question -

I am ready to do another oil change, Would it be a good idea to drain the oil before doing this, or does the mcct not have anything to do with the oily bits?

Thanks
Andrew

the MCCT conversion si very simple.. two TOC MCCTs one for the front cylinder and one for the rear.. the front one is easy to get to, the rear is a little harder... seeing as you are a cautious wrencher anticipate 45 minute max to do it. You will probably get it done in a matter of 15-20 minutes... no need to drain the oil, but if you are already going to do it.. perfect time to replace them while you are waiting for the oil to drain.

It's a funny coincidence how the video is centered around the ACCT most of the time

I never realized that till you pointed it out.

Can somebody explain in plain language what the acct/mcct actually does?

Thanks
