    Rear brakes are done. I picked up a length of oil cooler line so it will have oil in it soon then probably cleaning switches. Before the vac it used to be a length of silicone fish tank air tubing for bleeding.

    I need to find a piece of tubing to fit the petcock, one was missing. The fuel system is almost there otherwise.

    Update coming.... Carbs delayed cause someone showed me the tees made of plastic are better off being replaced by aluminum.... can't wait to hear her running.

    Oil cooler is on and she has a belly full of Valvoline 4 stroke motorcycle oil.

    Rick gave me some bad news about the carbs, bad diaphragms...he placed them on order and they will be good as new soon. They don't come cheap. IMG_20200118_105955.jpg

    Sorry to hear about the diaphragms, at least they are not obsolete. Looking for repair parts that have been out of production for eons is a pain. I have been very lucky to find most of what I've needed over the years. Other than the carbs, is everything else ready?

    I still have a petcock missing a nipple. It's an odd size OD but the plan is to get a barbed brass nipple, Chuck it up in the drill and sand it down with 80 grit to a good OD then glue it in with some JB weld.

    I'll have to fit a couple of fuel filters in since my screens are beat.

    I'm getting close with the limited time there is available to work on it.

    That is VERY close indeed! I have some small clear fuel filters I use on most of my bikes. The 79 is not here, but I'm fairly certain I placed them between the intake boots for a less cluttered look. I change them annually so inspecting them is not an issue for me. There is likely room to raise them up to where you could see them easier and still use the same location. YMMV

    Almost identical. I don't ride hard that often but I've never noticed any hesitation. ( From the bike that is!)

    I use the same one only with a 90 instead of straight.

    :hello: Just don't buy them from Harbor Freight. I used to use that same style on our small dirt bikes and they came apart.

    These are the two brands I have been using. I prefer the K&N, but only because I've been using them longer. Like Markus, I too have a bike that requires the 90 degree filter. I keep an assortment for 1/4" amd 5/16" ID lines. IMG_6676.jpg IMG_6803.jpg

    I kinda like the screen vs the stone. They seem to be easier to tell if things are getting nasty on the incoming fuel.

    I prefer the brass filters. I've had the others come apart when they get old.

    These bikes are tight with the octopus coming from the diaphragm, tucking the cone filters between the intake boots looks like the way to go...thanks for the input. Advance Auto carries the cones with brass good for ethanol e85 fuel.

    Floats are officially "sinkers" this rack of carbs were a mess, no wonder someone sat it in the corner...or maybe something else went South then it was parked then the carbs rotted...let's hope for the first. Replacement floats incoming. SANY1220.jpg SANY1185.jpg

    Pics from the bench of Rick West, I sure don't make things easy on him with the crap I send over.
