important news about balancer doohickey!!!!!

Post by David McClymont » Thu Mar 21, 2002 11:52 pm

Just been catching up on all of the posts.... been away for awhile... and noticed that the balancer DooHickey is still making news... Well I thought I would give people some information on it... First of all... before I say anything... if you can buy one of Jake's aftermarket jobs... go for it... I'm sure that will be a big improvement.... if you are keen to try and fix it yourself, here's a little information about it. Kawasaki seem to have 2 versions of the DooHicky... the earlier pressed metal version wasn't strong enough to cope with the job, and Kawasaki quickly brought out a thicker 2 piece job which was welded together. However, because this is a thicker piece, the circlip which held the original one in place could no longer be installed (someone asked about this a few days ago ). I'm not sure if this was rectified in later models... Anyway... as everyone knows... the new DooHicky still breaks! --------------------------- A SOLUTION --------------------------- Anyway... it is my believe that this piece is failing due to improper heat treatment... something that you should be able to rectify yourself. Welding a small piece like this can often lead to very fast cooling - effectively embrittling the piece... To rectify this, the DooHicky should be placed into a kiln (go to local pottery or hobby ceramics shop, or go to an engineering firm) and heated up pretty bloody hot (red hot), and let cool over a number of hours in the kiln. This will give you a nice uniform metallic grain structure, although it will be pretty weak at this stage. Once it has cooled, you should reheat it again- this time to around 200 degrees C, and then take it out and dunk (quench) it in a dish of oil (not water). This will toughen up the piece so that you shouldn't have any more problems with it. I cant guarantee that this will be the cure-all... but I have talked to some Material Engineers that I know and they seem to agree with this. Other people on this list might like to comment. cheers David McClymont A1 A1

Ok, exactly what piece is this? Is this the one that has a circle on one end, and then a banana shaped oblong area at the other? The one that seems to shatter into numerous pieces? Ryan

Yep...that's the one. Someone on the list called it the DooHickey and apparently its the official name for it now!! otherwise it is known as an "idler" something-or-other.. -----Original Message----- From: Ryan Newman [mailto:silverghost@...] Sent: Friday, March 22, 2002 4:05 PM To: KLR650 Subject: Re: [DSN_klr650] Important news about Balancer DooHickey!!!!!

I didn't think any aftermarket one were on the market.
