LF200GY-2 Year 2007

[Diggy]

Hello

I just took out my carb and going to replace it with a newer style with better jets. When I took off the carb I found a 2 things that are maybe I can get some good tips on what I should do and what to get.

1. When I turned my gas tank on the off position, and I took the hose out of that adapter thing, I am getting a small leak of gas dripping very slowly. I tried moving my little shut off valve back slowly to see if it would stop, it does NOT stop and I still get that slow drip of gas coming out. Good thing I found this out because the 1st owners that had the bike did not know about this problem and it was feeling up the carb slowly. BAD BAD. So would anyone know of something that I can buy that will fit perfectly on the LF200GY-2 gas screw thing and any tips on a GOOD shut off/full tank/reserve switchy thingy.

2. The air box that is with the LF200GY-2 is kinda big and bulky, Im not to sure what the air box does but inside is a filter thing too. Would anyone know of something better to replace the air box and how to hook it up etc.

Please any tips on what to do would be much appreciated. Getting a new carb with new jets and if I do get a new air box thing what would this do to my bike? Does it speed it up or does it just run smoother?

Thank you for your help.
