    I have been learning a ton about Carburetors Lately... Thanks to XJ Bikes and Rickomatic.

    Now I am curious... I am by no means any kind of an expert, but right now with the small problems I have with my bike, like the starter, setting the carburetors is becoming more difficult... If the engine cuts off during adjustments, I have to take it off the stand and push start it... Getting tiring.

    Well yesterday, out to the market on the bike after a bit of rain and the bike wouldn't push start... (Rear tire slid on the wet ground rather than grabbing for the push / bump start) Anyway, lost my balance in all the exhaustion from pushing and now I need a new right hand turn signal... Fell over. Oops - and embarrassing. Not hurt though...

    Since then, I have decided to wait until I get the starter repaired before I get into the carburetors.

    So this morning I wake up with this crazy Idea in my head... With all the bikes for sale on the market, would it be un-heard of for me to buy a bike for just the engine? Something I could put on a bench? Simply for the tuning of Carburetors? I think I can find a used beat up bike for very little money then another couple hundred in a bench design...

    With an engine on a bench, I would be able to hook a load up to it, fan cool it, and set pipes outside... I could tune carburetors all winter...
    It would be so nice to be able to run the right size screw driver right down into the mixture screws with out having to go around a gas tank, frame work or electrical wires...

    I am thinking in the way of the machines I work on, Some years ago we built a bench test device for electric motors after a rebuild... Just to test a motor under a load... Almost every electric motor will run after a rebuild, but we needed to find out how hot they were going to get under a load and see if they were going to last more than a day... It was very primitive, but it worked.

    :?: Question. :?:
    Do the fine tuning adjustments vary from engine to engine? or is it just carburetor to carburetor? Is this something that can be set on one engine of same size and be right on the original engine?

    I realize, ultimately, this is not really practical unless it was my job to tune carburetors... and probably only able to tune that specific CC of Engine... In my case, 650cc Maxims....

    Just wondering. looking for some second opinions...

    Nice idea, but the carbs are fine-tuned to match the specific engine.

    My trick pilot adjusting screwdriver is a 2" burnt welding rod, hammered flat, and ground square.

    If you want to build something, build a 4 tube Manometer, water filled carb sync-ing tool. Search topic - Manometer.

    Sorry to hear you dropped your bike. If you have to bump start in the rain again, go for second gear, park on a hill.
