I used 1 oring, 2 orings, wire, huge paper clips, bread wrappers (twist ties), almost anything imaginable. They all behaved similarly in that the more they are tied together, the more they displayed the graphs of the 2 orings (or greater). Anything works. If an oring is put on and it breaks it is not a big deal, it just reverts to however it was running before the oring. Generally an oring is advised because it is possible that the AP adjustment screw to be set so when the throttle is wide open there is a space between the AP arm and the other parts of the linkage - and you would be putting stress on the parts if that was the case. It is an incredibly simple concept to show in person, tough to convey in words, but basically if the throttle is wide open and the AP arm does not touch what it is supposed to be touching, then that is not good. In addition other bike manufacturers have different AP linkage and AP diaphragm stud lengths which adds to the issue. Ergo that is why people say 'oring' instead of wiring the linkage together. In addition, I've not been able to get wired AP linkage to behave as consistently as the oring because they tend to loosen up. But anything works and you will get a bit more snap when wacking the throttle. edit: Watch this video, when the AP screw is less than 2.25mm then there is space between the linkage - that would be when wiring the linkage would not be a good thing. Nothing terrible, just not ideal. [youtube]ool_jiy4kxQ[/youtube] EDIT 2: All sorts of strange AP linkages have been developed, and many short videos on you tube about them. Here is a linkage that could use some attention: http://www.youtube.com/watch?v=pzDVurcKmJo&NR=1 .
Just watch that video and pause it, it is pretty evident how to set the screw without even measuring it.
paper clips and bread twist ties....lol Coffee makes some great points and I forgot my YMM/WV disclaimer dadgummit... Wire's been on mine fer 50+ hours of whompin....so far so good. Thanks fer jinxn' me man.... I'll think of ya after I loop out into some tree tops and end up hikin' home.
Awesome info. I'll watch that video when I get home. YouTube is blocked here at work... as it probably should be. lol.
I thought about using siezing wire instead of an "O" ring and decided that a little pliability was probably beter than ridgidity so I plumbed for the "O" ring option. With Coffee's input it reinforces my perspective.
In my experiences with KTM's, Hondas, and Yammies, the o-rings have been the superior choice. The hard wired option always seemed to produce some quirky issue with throttle response under certain conditions. I've never had issues with using O-rings. Incidentally, I've never had an O-ring to break... although I've never owned the same bike for more than 2 years.
