Need help diagnosing a problem

Too many people to reply to so look for the answer to your question here!
Zwartie, thank you, I  will do that for now on! I always thought the kill switch was proper procedure.

Simi Ed: I owned the bike for 2 weeks, problem just seemed to spring up over night. However, we did have a Dust Storm that I rode for 5 minutes in, but the issue happened 2 days after. Bike has been untouched since I bought it.

FJ1289: I honestly couldn't tell, it's just a meter that says "Rich" on top and "Lean" on bottom with an electronic led bar that moves up and down. I'm also upgrading the battery soon to a Shorai lithium.

Woohoo! She's all fixed up. My mechanic said the vacuum lines (for the fuel pump I assume?) were all rotted out and my spark plugs were toast from running lean because of the vacuum leak. Ontop of that he cleaned up some of my bike for free (awesome dude). My bike is once again screaming down the highway and I can enjoy the kookaloo again!  :dance2: I just wish I had my own garage, the bike would feel more personal and special to me if I could work on it myself lol.

Glad you they got it sorted out for you.

No vacuum lines to the fuel pump. Must be something else...

Did the mechanic say where your oil leak was coming from?

Glad it's all sorted. Buy that mechanic a pizza and a 6 pack.

Ride Well...... Pat

Targan,

Glad to hear that the problem was fixed.  What year FJ do you have there?  The early FJ bikes do not have a fuel pump, but they do have a fuel petcock that is opened only by engine vacuum.  If the vacuum hose to the petcock goes bad on one of those bikes, it usually won't even run.  As it is, that sounds like a good fix, and fairly cheap.  Yeah, you should buy the mechanic a pizza, or lunch, or his favorite poison.

I have an 89. That's good to know! That's probably what he was refering to.
I treat my mechanic well, always tip ontop of cost of repair (cause he does more than I ask), and I've brought him a lot of business from my friends. We need more people like him in this world lol.

I actually havent seen any oil on the ground yet. I never mentioned the leak to him cause it was so small i figured ill just wait till my next payday. No idea if he fixed that too without telling me lol.

Targan,

Okay, the '89 does have a fuel pump, and a fuel filter.  No matter, though, because any ratty vacuum hoses can spell trouble. 
If fuel starvation happens again, the fuel filter will be the first place to look.

Oooo, that might be my problem with my '86.  When hot, it just will not start.  Zapped it with starting fluid and it starts.  I am assuming that when the engine is running, it creates enough vacuum to pull  the petcock open.
Starts a bit hard when cold too, but does start.  So, perhaps the vac hose is swelling it's leak open when hot.... :bye2:

Crack the throttle open about an 1/8 when cranking. It helps my hot starts... #40 pilots also helped, less lean at start up...

Vacuum hose collapses on itself when hot, it's vacuum hose.
