grambo and marble help for a newbie

Hi all,
In reading these boards, i've heard of the marble trick(for popping) and the grambo trick( for engine tick).

They both seem to be easy fixes but I cant seem to find the thread which shows it all off for a newbie.

I need help

At the top of this screen, next to the bike, is a small search window.
Enter "grambo" and press <Enter>
Enter "marble" and press <Enter>
You're right, both are extremely easy to do.

theres a link in my signature that tells you how to conver your acct to a mcct. but also in there it tells you with the engine running to take the cap screw off the front cylinder acct, there is a small flat head screw inside it, if you see it jumping around when you hear the tick that is your culprit. to grambo it, shut the engine off, turn the screw clockwise a full turn and pull the screwdriver out and let it snap back, that might cure the problem for awhile, if not you might consider the homemade conversion for 10 bucks or less a cylinder like many of us have or purchase machined mccts from toc manufacturing for 50 bucks a peice! good luck

First, the marble thing does work, but you will be a lot better off just getting rid of the entire air injection system, and capping off the connections at the head, either with coasters, which look nicer, or like I did, with rubber plugs. Your bike will not only run better, but you will get rid of a WHOLE BUNCH of useless junk that clutters up the bike. It made me feel real good to throw mine in the trash can.

The "Grambo trick" is more of a diagnostic tool than a fix. If doing it quietens your engine down noticeably, then you have worn out cam chain tensioners. The noise will come back. A variation on this is to actually turn the screw counterclockwise, which advances the plunger and stops the noise. But just like the Grambo trick, it will come back. I highly recommend the TOC manual tensioners. I have been using them for over 40,000 miles, and their quality is like night and day over the cheesy oem tensioners.

I am a motorcyclist, NOT a biker.
