300 EXC Gear Shifting Change

[teric625]

I want to change my 1-down - 4-up around to 1-up / 4-down, and would like some opinions about this. Is it not really worth it with extra linkage and other adjustments, or does it just sound dumb? First gear is "1-up" as in "GP-shift" with all my other bikes (street and roadrace), and wonder if anyone else tried this. Thanks for any help you can give a novice,
Tom

Wow that would be a serious project.

How good are you on a CNC lathe and at gear cutting?

[teric625]

Yes well ok it seems at first glance it could be slightly steep of a consept for lots of riders, and yes I have experience on lathe and milling machines, but more importantly I have a degree in ethnic engineering. Being smart about it and keeping safety in mind, I can come up with the piece that would work, but what are you refering to as to 'gear-cutting', and couldn't I adapt a reverse gear change kit for another KTM to fiut mine??

I would pose this question on thumpertalk.com but not make it KTM specific.

I think there would be a lot more folks that have transmission experience
there.

I myself am a mechanical engineer, but I don't have much experience with
automotive.

That's good, I'll check that out thanks! I think it's all only a customizing sort of thing, but it's not impossible. As an artist too, I can weld something to work, and maybe I'll patten / copywright it - who knows... I don't see very many riders looking to do this kind of bike mod, it's probably me going through my own 'Scientific Method' to an end.
Happy trails.

I'm switching my YAM 400 trackbike to GP shift also. On a dirtbike application is a thought to consider. Please let us know, what progress you make on this.I'll give it some attention/research myself ..

[teric625]

Sure I'll try to do that, and maybe show some pictures as well. The whole thing about this is probably just mental, but I like to be consistant.

I'm too interested on how to change a dirt bike to GP shift. I am a new dirt bike rider but a long time street / road race rider. I'm way to used to GP shift and going back to standard shift on a dirt bike drives me nuts.

[teric625]

Yes I agree with you, that's why I'm trying to do this. Even though I have GP shifting on both my road race bikes and my street bike, sometimes I still screw up by downshifting in street traffic when I think I'm upshifting. I hate it when that happens.
