FJ heat

Hey guys 

Will FJ's turn themselves off if they're overhot?

Hey guys 

Will FJ's turn themselves off if they're overhot?

Sure, eventually...   

[theLeopard]

I only ask cause it happened a couple times when I was idling at a light off the freeway the past few weeks.

Then I rode to the TWIC office off the 15&8 today (40miles there) going about 80 (5000rpm).
Got to the office fine, needed a money order, bike quit on me a mile down the street at a light.
Started back up just fine, quit on me again when I was leaving the office for the 2nd time.

Been having a bit of increasing difficulty turning her over lately, was thinking battery since I did some compression checks but the battery is 2 months new....

Methinks your carbs are still f'd up...

[theLeopard]

why 

[simi_ed]

Because when FJs run crappy, it's almost always carbs.  And I've yet to see you post "my FJ is running great" or anything close.  When that happens, then you're carbs are free from suspicion (for a little while!).  When mine died at idle it was flooding, leaking o-rings. 
Ready for another bout with the carbs?

[theLeopard]

nah, not yet.
I replaced every rubber in there and I haven't been overflowing.

idles steady at 1000, pulls great through the band, no problems in any of the gears except for the clutch slipped twice last month.

and when it dies the idle isn't acting up. it sits at 1000rpm steady then just shuts off, like I hit the killswitch.

any other suggestions? some guy said I should rebuild the carbs because my clutch slipped so i'm skeptical. my guess is that's the stock response 
course I probably managed to piss off 90% of the forum with this post. wish me luck

Did you read the responses to your post on slipping clutch? Some on this forum may have owned there FJ longer than you have been alive. Many have had more than one. When three or four members are telling you carbs listen. This is not meant as a put down. Just trying to get you to realize you are looking in he wrong place. Everything you keep posting screams carbs carbs carbs. Just trying to help.

alright what do you suggest I do to the carbs?

they're clean, with new rubbers, on stock settings, and aren't overflowing.

If the engine runs well, idles steady but dies like hitting the kill switch at idle when it is hot it isn't the carbs.

Nothing. It sounds electrical if your engine shutting down description is accurate.

Because there are small passages in those carbs that are easy to miss and the bike sat for some time this compounds these problems. Maybe the fuel filter is plugged or pump is not working correctly. Everything keeps pointing back to carbs/fuel system.

I haven't tabled the carbs completely kurt I just don't think that's the main problem.

i'm glad someone else said electrical cause i was just on my way out the door to pick up a voltmeter and work my way thru chapter6.
if you think of anything else, or specific, keep me posted.

Leopard best of luck. Hope you find the problem.

Carbs sputter to a stop...like running out of fuel. Hard, sudden engine stops are electrical. Look elsewhere.
