98 1100 STX carb rebuild question
 

I recently purchased a 98 1100 STX. Has about 100 hours on it and it looks like it was well taken care of.

I did a water test and it ran good but I noticed the one spark plug was fouled. I took the carburetor case off and noticed the duct was all broken so I suspect that caused a rich fuel mixture.

I will check the pop off pressure to make sure that's within spec but I can't seem to find a genuine Keihin CDCV rebuild kit. Lots of aftermarket ones on eBay and on sites like SBT and jetskiparts.com but I've read mixed reviews on aftermarket carb rebuild kits.

If you can recommend a rebuild kit, it would be greatly appreciated.

Thanks!
