No problem here to help, glad you found some that will work. :good2: Just putting it out there for those that didn't know already. Shipping at most is 3 business days from us but 90% of the time it is 2 day coast to coast.

Honeymoon yes. I had planned on at least few hours of beach time......

always sunny. hot. very hot. its been very dry this year, record drought. if you come get in touch with me, i have a tour business. to make sure you have a ton of fun. although i leave to the philippines in 12 days and im not sure when i come back. probably mid october. also tell me before u book a place. i have the IDEAL hotel for you.

back to that moody b*tch of a bike. just took her for a half hour ride after reinstalling the carbs. doesnt seem to flood anymore, still too hot to pull the new spark plugs out to read them but even though it turned on right away and runs very smooth in idle, still same problem. first minute i would say she runs pretty powerful maybe 70% of what she is supposed to run hp wise, as soon i get over 5k total hesitation and as i keep driving and she gets hotter is gets worse and into lower rpm ranges too. after 15-20 min hesitates a lot, then there is a spot between 3500 and 5000 rpm when she runs kind of smooth but for sure way beyond what this engine could deliver.. just one big hesitation.. which leeds me to believe once more its electrical. but im gonna wait a little and read the plugs. its frustrating.

what i can tell though so far is that the handling is superb. feels amazing, especially considering its a bike from 85. very comfortable, cornering and handling very precise. cant wait to have her running normal and really enjoy this great bike. its a keeper for sure.

Ok, the flooding is stopped, good.

Are *all* the little tiny holes in your emulsion tubes (aka jet nozzles, needle jets) open and clear?

It sounds like your bike might be running lean (getting hot) when on the needle jet (mid range)

On the electrical side, clean the contacts in the run/stop switch (on your right handlebar) It powers the ignition box.
While you at it, do your charging system a favor: Under the right side panel is a red plug. Take that plug apart and check to see if it's melted.

alright. yeah im still not there with the carbs. just took out the sparks.

1 + 4 way too lean. completely white
2 completely fouled black
3 well. almost good. the center is light brown but inside its black too but def going in the right direction.

i set up all the floats on the same level as stated in the manual. 22mm i believe. i made a tool to measure it easier.

can it really be THAT off from a equal position of the floats? im guessing the next step would be to set 1 + 4 to a little more extreme rich setting, and 2 to a very lean one.

i took out the main jets when i cleaned it, the other that is deeper in a hole (im not sure which one was that) i didnt get out cause it was too deep to reach with my screw driver. other than that i cleaned it was a ton of carb cleaner, wd40, needles and in the end blew the hell out of it with air pressure. now im thinking maybe giving it a bath over night in something but not sure.

which panel are you talking about? to be sure im looking at the right place.

The side panel on the right side.
Scroll down: http://www.fjowners.com/index.php?topic=14089.0

Take the slides out, flip the carbs over, take the mains out, now with the mains out you can push up on the emulsion tubes and take them out from the top.
Did you take your pilot jets out?

Perhaps this video will help you. http://www.fjowners.com/index.php?topic=12407.0

great video. i will take that out for the 4th time tomorrow and get it really completely apart. problaby something is still dirty and thats why 2 of them are so lean. i dont have any plugs to cover the pilot jets in my carbs. is that a problem?
