Buz here. Newby. Found a 93 FJ1200A (ABS) with 12K miles. Really nice and clean. Progressive fork springs, Corbin seat and K&N air filter otherwise stock.

Above 2k runs like a freight train. Will not idle. Way lean. Pulled carbs. Have stock 155 air and 37.5 fuel jets in idle circuit. Idle fuel jets were clogged. Will clean the carbs and put all back together. Plugs tan brown indicating lean.

Question: Given a K&N air filter, should that alone push me up to a larger Idle fuel jet? Say a 40 or 42? Also, living in Atlanta, should I go to a cooler spark plug?

Thx for the help. Have already learned a lot from this site. E.G. I dropped the rear frame section to ease in air filter housing removal. Also, before dis-assembly, with engine running, did the spray test for air leaks. Found none.

Again, many thanks.

PS: Any Atlanta FJ members active?

I recently bought an 86 FJ1200. The old girl had been dropped on the right side and has sat in a garage for at least six years that I know of, probably more.
Call me sick or stupid but I can see past the scrapes and the mouse nest in the air box. As I write this I have the carbs sitting on the table next to me in a state of disassembly.
I have already gotten some information from the forum prior to subscribing and registering. I look forward to getting the old girl running shortly so I can take her for my maiden ride.

To do list:
1. Clean out carbs
  1a. Replace choke cable
2. Clutch master cylinder rebuild
3. Replace clutch slave cylinder
4. Oil change and spin on oil filter
5. Replace front brake lever
6. Replace rear tire

Be safe out there.

Hi I'm Doc
Old monopod, been riding all my adult life.

Nice to meet you 

Hey guys I just purchased a 87 fj1200. It's in exelent condition motor runs strong. 50k miles on it. One thing tho the clutch slips at about 7k.... curious to see if anyone had a similar issue and is it a quick fix replacing the clutch disk and plates.... also after riding for a while at idle a little top end noise. Not all the time but I just did a yamalube oil change. 10/40 as I saw some recommendations to use that particular weight. Any advise would help as I'm a new owner. Thanks in advance

Thanks for having me. I received a 1984 Yamaha FJ 1100 as payment for a job I did, but I have no intentions of keeping it. My FJ1100 came to me as a basket case and it's almost put back together. I'll be trading my FJ1100 for a much smaller engine bike as soon as it's a complete bike again. I'll post some pics soon.
