Im replacing the front and rear sprockets on my 1991 suzuki gsx600 katana. I'm sure either the front probably the rear as well will need to be torqued, I'm just curious how mny pounds i need to torque it down.

I think there is a vacuum line which goes to the tank from the carburator

GSX 600F Katana 1989-1991
GSX 600F Katana 1989-1991
OEM Gear Ratio - 14T Front Sprocket / 46T Rear Sprocket OEM Chain - 530 Pitch / 112 Links

Chain size should be a 530 link. Going smaller on the rear gives more speed, but less power!!! Going bigger on the front gives more speed also.
Keep in mind that one tooth bigger on the front sprocket is equal to 3.5 teeth smaller on the rear.

ok fuel fill lines are the 2 lines between carbs 1 n 2 and 3 n 4 toward the rear of the bike the 2 hoses coming out just in front of them are float bowl overflows that just get criss crossed over the carbs and ran thru the little holders on the frame. the only vacuum line is coming out of the side of carb 4, this line goes to the nipple on the petcock facing away from the knob. as for the fill lines the 1 between 1 n 2 goes to the nipple facing the rear of the bike and 3 n 4 goes to the 1 facing the front of the bike. hope this helps here is a link for a free service manual download. http://www.files.michaelmcmahon.org/1988-1997-GSX600-750-1100F-R.pdf try using www.katriders.com it is a lot more helpful than this site for katana issues.
