KTM front end with 17mm axle diameter

So I have struck a disaster. I was going to use a used 50mm WP Extreme front end on my HD sportster as a Dual Sport convert.. already got new Talon Hub on Sun Rims few weeks ago.. paid for custom fork springs kit.. unfortunately I nicked the fork tube badly yesterday (freak accident) and replacing it will be hard and cost prohibitive for me.. I am uncomfortable with the idea of using fork tube with that deep nick so I am forced to explore other option..

I've considered another front end from Yamaha YZ250 but not sure about the front axle size? I understand that exc front end has 17mm axle? But which year and what model #? I am not familiar with KTM myself and hoping some of you KTM guys can chime in to give me some helpful tip..

I've also considered having axle shaved down to 17mm in the center but am concerned about the strength of axle with it being small at the middle.

Unless one of you would like to buy a new unused Sun Rims (Buchanan's Spoke) with Talon hub from me? (on the right) It's a 2.15X21 with KTM Talon Hub from Dubyausa.com

Wp regular forks were used on pre2001 lc4 640/400 like the adventure and enduro
1999-2000 might be a few earlier model. Some 2 stroke had them too.

Then they were some upside down forks earlier (first generation) not sure exactly which model.

Mere or less anything ktm pre2000 you have a good chance of being 17mm

Then 2001-2002 is 20mm
Post 2002 most of it is 26mm

Ktm950 are different

Take the fork to a good hydraulic shop and see what they can do to repair it for you ..... Might be far cheaper than any of the alternatives.

They fix these problems all time , they may be able to fill it and re chrome it faster and cheaper than you think.

Is this the sportster with the hand built aluminum tank I was recently drooling on in a magazine article?

I tried Fork By Frank that was recommended to me here on Advrider, and the hydraulic shop around here can't fix it.

I think I have no choice but to try and cover it with plastic steel epoxy here.

Lukerlox, the sportster you were drooling over can be seen at build thread here
