Cheap and easy valve adjust tool
« on: August 14, 2008, 07:55:10 AM »
your MOM is cheap and easy!   ;D 8) ;D

sorry, just had to get that out of my system.   ;D






anyway... homemade valve adjust tool...










1- 10mm deep socket (12 point works best for this particular application)
1- old, small, least used size, box end wrench (keep it small, too much torque on the lock nuts is bad... ideal size is roughly the same size as the 3/8 square drive in the socket)
1 old screwdriver that will fit thru 3/8" square drive in socket
1- loctite epoxy... this stuff is strong!  i like this brand since it is clear, unlike jbweld.

first, make sure to scar up the mating surfaces a bit for good adhesion
mix epoxy
dip both mating surfaces in epoxy, wait a minute or two then join the two pieces
let cure for about 15 minutes
then really go at it w/ more epoxy, i tried to completely encase the end of the box end, then also took the epoxy down inside the box end and socket drive... this should ensure that torque applied to the new tool won't just snap it apart.  w/ the 12 point box end and the square drive, the epoxy will mesh and hardens in those and just really won't let go at this point.
lastly, insert screwdriver or square bit driver and

ADJUST THOSE VALVES!   ;D

i had everything except the extra deep socket... not gonna give up one of the most important tools in my box w/out replacing it.   ;)
the craftsman 10mm was 4.99 at sears.  can't beat a 5 dollar tool that was supposed to cost at least 3 times that and may or may not be in stock at only motorcycle shops. 

i know, i know... i could've welded it and it would be even stronger... i would've except i have no welder, and now that its cured, i have 100% faith that the small amount of torque needed for the application will not be too much for the new tool.  now, i probably wouldn't use it to break the nuts free, but its not really needed for that anyway.

just made it last night for use today... going out to give it a try.   :)

hey thanks!
works like a charm... just make sure to put lots of epoxy on.  i actually broke it cranking on it pretty hard just to see what it would take, re-epoxied it w/ much more epoxy the 2nd go around and it held like it was supposed to, even w/ a few hard cranks again just to see.
i like being able to switch screwdrivers too... working on maddog's 650 and the frame was in the way w/ one driver so i just switched to a longer screwdriver to get the handle above the frame.  in the process, i found out that a longer screwdriver just made it easier all around.

what you can't really see in the pictures is a fairly large bulb all the way around where the epoxy is... an 1/8" thick is some areas... just gotta hold the tool and swirl it around like you would creem in a tank until it hardens.

I've never understood the need for this type of tool, I just use a box end wrench and a screwdriver  ???   What am I missing?

Well built, though.  :)

some CBs... like the 650 that i was working on yesterday... have the locknuts/set screws down much further than is reachable by a box end.   ;)

(i can do it w/ a box end and screwdriver on my 350)
