Re: easy carb support 76 CB360, before & after
My carbs are sagging. maybe making my bike run richer. I needed a support. I looked at it for 10 minutes. took a break. another 5 minutes...and BAM. there is a little square cast into carb between filter and bowl, AND a motor mount directly under.
It wont hinder filter installation or bowl removal. It will add one more step to carb removal, cause you gotta get it out of the way to pull carbs...but its only one bolt.
I made it from a scrap piece of flat, drilled a hole cut w chopsaw, bent it, filed edges, and primed it...10 minutes. I believe its gonna work great. when installed it raises both carbs to level...if I do need to make one for left it will be a little trickier. but basically the same, a little longer, drill a hole in mount, and bent a little differently.
I do need to add PJs name to this...
Saturday while i was trying some new jetting I found I had a rich condition. Thats when i noticed carbs sagging.
i worte PJ and asked what he thought of sagging carbs...He confimed my theory, It may lead to a rich condition.
I asked him if he had a fix...he said he temporaried carbs w a bungee cord...and used springs as a permanent fix.
I havent seen his spring idea...so it may very well be a better solution than my brackets.
In primer for pics...so you can see it better...will be black.
The little notch in the end "traps" it in carb casting so it cant work out sideways. Maybe add a little piece of rubber to end to insulated it, if I see wear in carb casing.
heres the star washer I was talking about. Place it between the bracket and the motor mount. Not under the bolt head, apply a drop of purple lock tite or thread sealant to keep bolt from galling or vibrating loose, then tighten to torque specs. Im 99.9 % sure this is the last thing that will vibrate loose on your bike. Also being secured to the engine mount...and carbs being secured to engine. If there is any flexing, wiggling or bouncing going on there that might cause carb insulators any undo stress. You may have a bigger problem than sagging carbs. Also as I mentioned in original post I may add a peice of rubber to end of bracket to insulate carb body from wear caused by vibration. Like the title states "prototype".
OK, here is what I have done...cut the notch a little wider, bout 1/4 inch. Slit a small peice of fuel line and snapped it in notch. so it insulates between carb body and bracket. maybe post a pic later.
Also it cant slide off the carb...the notch in bracket has it trapped in the little square on the underside of carb casting between bowl and filter.
Now there is a small piece of rubber fuel line trapped between the two also, not in this pic
Finished support. with insulator made of fuel line, painted black and installed. I am pretty happy. I dont notice it at all.
Its there behind the kick starter.
