Old School, New Twist

Ok so I'm doing a conversion to my buddies old school 490 which is the old style forks with front and rear drum brakes. I have got my hands on a 98-2000 yz 250 top and bottom triple clamp and I am using some brand new prototype inverted forks my friend already had. Problem is I don't know for sure what they were originally for but I think they are KX forks, 06 to 08, which brings me to my question, They are all mounted up but what front rim do I try? YZ? I don't think the axle bolt is right size, KX, CR? Can any of these cross over , ex CR to KX, if so great which ones fit what, second brake caliper, how do I figure out which one is the right one without having them to try one at a time?

Well that is it, if I can just figure out what rim/brake combo will fit and work right then the conversion is done and my buddy is all smiles.

      A tiny clear rubber tube on bottom of carb.  On bottom sort of on side, by floats, the other end just hanging down.  Was it always like this? Or does the other end go somewhere?  Today after multiple trys with kick, choke on/off ,,,fuel keeps pouring out the tube.  This bike has always been hard to start.   Thanx  guys!

      I just did my valve adjustments and put my YZ250f back together as far as the valves, shims buckets and cam covers on but I need adhesive for the plastic valve/cam cover and I am stumped as far as what to use and where to get it or even what to call it! Need to get some soon im in need of a ride!

      Hey guys, I bought this YZ85 and came to realise the clutch wasnt working, so I drained the oil (Jet black) and pulled the plates out and cleaned them. I assumed finding a torque wrench would be easier than it has been. Does anyone know how to torque the clutch springs to spec without a wrench? Any insight helps.
