    Tool tubes are cool. Ugly, but cool.

    So yesterday I rode 140 miles ,bike ran good ,but I've noticed an occasional low speed buck , today was cooler but very windy. So I recently rebuilt a spare set of carbs , I swapped the number 1 slide because I did not like how it moved in the bore. So I swapped diapram and slide and this solved the bucking at low speed . The slides were all seized on the spare carbs so I guess this slide was dragging slightly .

    Finally did a bench synchronize on my carbs, solved the 3000 rpm idle problem.

    Pulled the carbs off, numbered the bodies. Broke the rack apart pulled out the butterfiles and messed with the diaphragms and jet needles a bit. Looks like PO took a hammer and screwdriver to them as 3 of the 4 needles were very obviously bent and had been dislodged from their plastic retainers. The metal parts of the diaphragms were scarred up and some of the main jet nozzles were in pretty bad shape. What the heck was that guy thinking?? I'm impressed that he even had it running at all. Also he had told me he had cleaned the carbs out on his "carb machine" Said he did it twice even! Lolz, man. It's ok. It ran before, just not very well. Soon I'll have it all straightened out and she'll be running right again.

    Oh dear, those carbs have a serious case of the PO (previous owner) I just went through a spare set of carbs that the slides were stuck and the throttle plates were seized, but now all tip top shape. Your slides most likely should be replaced and those needles are toast. Good luck

    Hah, I spoke too soon! Turns out my rebuild kit has those needles in it along with the jets, nozzles and even idle mixture screws. No need to make or salvage any of those hammered parts. I got my stuff mostly cleaned up today but will pick up some pipe cleaners and look for any kind of useful looking cleaning brushes and will go over the carb bodies a second time tomorrow.

    Got paint and started painting the frame. There was a bit of surface rust on the frame and I wanted to clean it all up and protect the steel from corrosion so I will fix everything that needs done and hopefully have the bike back on the road next summer.

So I pulled carbs this evening , pulled float bowls were spotless , the jet for the enrichment well in the float bowl ,spraying cleaner was not plugged but could be better , soaking in MEK right now . Going to soak over night will see how this goes.

    Should have mailed them to me. I could have popped them out with the TIG.

    Soaked the repaired OE seat cover down with Armor All and stuffed it into a trash bag. Hopefully a few days soaking will soften it all up well. It's pliable but some of the foam and plastic beading needs some re-oiling. If that doesn't work well I'm going to spray it down with fluid film and see if that works better being stickier.

    First week back on the job after a two week vacation with the family. Weather was good, which cause me to feel guilty about slacking on my bike. So, took half a day off and finally got my engine out of the frame. Did some other stuff, too. Pics and more info in my build thread. Just felt good to get started again.
    Got a link for that (both the rebuild kit and the ATM-LP)? :)

    Rode home in the rain from work. Now works almost over again, 0% chance of rain! Oil change , gear oil change, new starter relay and testing ignition coils . Carbs need cleaned but honestly, I'm nervous. And measure shim clearance first? What if I lose a bunch of ride time:) kinda joking

    Yes shims should be done before you start to fine tune the rest of it.
