alt50 problem
i've got an 83 suzuki alt50 (3 wheeler). i wish i had a kasea 50 but i had the bike given to me and it seems to have all the items (mods) listed in this forum done. but maybe the older bikes were less restrictive to start with and didn't come with half the stuff. at any rate,
my exhaust has the washer restrictor removed, baffle and cap removed but the tail pipe is not cut 3" off.
my air cleaner has the back plate off with a uni foam insert and a womans' nylon covering it.
my carburetor manifold has the keyhole restrictor removed, the 2nd top pilot jet removed, and a 70mm main jet installed, and needle slide clears the flow opening completely
the automatic oil injector tank and hoses have been removed and i capped off the crank case inlet
the petcock is as clean as the carburetor and connected by a hose to the cylinder side of carb manifold
i'm running 40 to 1 mixture racing gas
i did not eliminate the brass sleeve located in the carb between the slide and the slide cover and raise the needle one clip position to make the needle higher. because all that was there was a spring and zig zag shaped clip (and carb slide cleared already).
the bike starts but only if the choke is on, and throttle adj screw way out so that it revs really high but dies when i give it gas or take off the choke. i was able to hold up the rear wheels and it would accept more gas but only with the choke on. but its running really shabby.
i noticed the main jet has a small section of tube (1/8" or so long) on it and the float is positioned in such a way so as to hit this at some point on its travel. maybe i put it (the float) back on the wrong side?
or is the nylon covered open air filter too much?
or is the 70mm main jet too much (stock was 57.5)?
or is the needle not installed back correctly?
or maybe something else? (i.e. unseen crud in the carb or petcock-2 strokes are so touchy when it comes to air/gas mixture)
or maybe i needed to plug the line that use to go from the oil injector to the carb?
or maybe the needle should be set up one notch raised?
can anyone help?
