Well thats an oddball.  I looked up the carb and its not called out.  Sometimes there is a clip that holds in the fuel line (steel part) into the carb. It looks like a fork but i can't be sure.  Have you removed the screw to see what it possibly does or is?

That's the thing. I did remove that screw while in the process of cleaning the Carburetor and I went to reinstall it and now notice that the hole is larger than the screw thread and it is not threaded. There must be something that it screwed into inside the casing of the carburetor that has dropped out of site. It really has me puzzeled? It does not run correct with the hole being open however if i plug it it seems to run fine.......?

Could have been a vacuum port?  For now i would put a dab of silicone over the hole and let it sit over night to properly dry. At least you can ride.  In the meantime you can research what it passably could be for. Maybe even take a ride out to your local Suzuki dealer and ask one of the mechanics or have them bring up a more detailed blow up of the carburetor.   I will keep looking as well to see what i can find.

      Where you like to ride and what riding does for you?
      By BuckBilly
      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.

      Brake handle question
      By mga
      on my left brake handle (for the rear brakes) there's two wires attached to it. What are these wires for? They can't be for the tail light, since it only has on filament  I tried to trace them, but i got lost in the harness. I checked wiring schematics, but didn't see anything like that.
      I'll post a pic later.

      Drive shafts question
      By mga
      2000 Big Bear 4x4 400.  
      do the front and rear drive shafts have to be lubricated? they have boots on them and i was wondering if i had to pull the boots off and grease the "U" joints? These are the ones close to the engine front and rear.

      Hoping against hope that you will tell me that my '86 225 Moto4 is not as bad as I think
      By DaveswMN
      Pulled my '86 Moto4 out of shed where it sat for 20 years. I knew it smoked. checked it over a little put in gas and it fired right up!! 
      Drove about 100 yards, ran about half throttle wouldn't idle.  Put on somenew parts, jug/piston and rings, carb and valve seals.
      'went together ok, tuned it over by hand about 6 revs whick went well. Hit the starter it fired for about 6 revs and quit. tried it again fired once and then th sound of something slipping like maybe chain slipping over spoket.
      Took cover off to watch cam sproket, hit starter again, heard same noise and the cam sproket was not turning but jumping a bit. Chain was still tight. You will probably tell me I need to split the lower case but hoping there mightbe something else.
      I don't fully understand the chain tightener, the plunger only moves about 1/4 inch, should it move much more than that when off the motor and compressing it by hand?
      Thanks for any thoughts.
