GS1100GK questions

[Anonymous]

Just bought '82 GS1100GK. I have a couple of questions before I get started getting it roadworthy.

If I were to put on the K&N air filters, do I need to rejet the carbs and are there any other considerations?

The left muffler has a rattle (more like a clanging) which seems to indicate something loose inside. Can these be repaired? Or is it replace only?

Both brake systems are somewhat gummy. There is a sludge inside the front reservoir. What should be used to flush the system? What are the chances an unapproved brake fluid was used and the hoses are dissolving?

Are there any problems with converting the engine oil along with the drive train oils to synthetic?

I'm sure there will be more questions. Thanks for any help.

For the brake system if it is gumed up bad I would sugest taking mastercyl and calapers apart use a spray brake cleaner or just use brake fluid to flush thru the system if you are not going to take it appart. If you have any question about the brake lines REPLACE them. I would stick with the stock air box & filter. K&N can be made to work. If you have the skills to properly rejet the carb, lots of trial and error to get it to work. I would check the heat shields on the muffler for a loose bracket

No problem converting to synthetic. This is a matter of personal choice. Go ahead and do it if it makes you feel better, but it won't harm the bike one bit. I use Honda or Suzuki or Valvoline 10W-40 dinosaur motorcycle oil. Works fine for me.

I agree with Lynn. Stick to the stock air intake system. Rebuild your brake calipers and flush the entire thing. You'll feel the difference right away.

Thanks for the help. The airbox is a mess, salvageable, but a mess. I'm thinking start at the front wheel and slowly work back. Should have a good rider when done.

If you can get the airbox straightened out you can buy a single K&N that replaces the stock filter element and you won't have to rejet it.

If you have a muffler with a removeable baffle, check to make sure it has the baffle material around it. Otherwise the baffle can rattle about a bit inside the pipe. The material will disintegrate over time. The pod filters are nice if you don't mind rejetting the carbs, they make getting your carb rack on and off a breeze., and if you're planning on adding a little performance to the bike it's not a bad way to go.
