Hi Guys, first time poster. Wondering anyone can help me out with my bike.
It's a 1992 or '93 Beta TR34 260cc Alp, Long Range. It's air-cooled, Dellorto PHBL, upside down forks. Got the bike from an old riding buddy later this summer and it was sitting in a barn for who knows how long.
First thing was to tear apart the carb and replace o-rings, gaskets etc. After getting it all together and fresh premix it fired right up and ran "pretty good". Played around with the fuel screw and idle and it always revved high. Not an air leak type of high rev, but way too high. Especially after going down my dead end road and the tractor path to the woods (up to 4th-5th gear).
Opening the choke (up) always clears it up but then when you put it the choke back (down) the revs kept climbing. Made for a really awkward woods ride. Lurching -not smooth and steady.
By accident left the choke up and it rides quite perfect. Nice and slow idle with throttle control right where you'd expect, in fact its quite awesome in the woods.
Wondering if this is by design? Since the bike has lights, horn and brackets for passenger pegs was it a dual setting (rich/lean) for road and woods/trials?
