I bought a 1984 R65 used and it came with Dellorto PHF 32s (aftermarket). The previous owner tapped them for VTO ports, so I balanced them at idle and at 3,000 rpm. In my mind, the bike seems to run like a top. No sputtering, backfiring, plenty of power.
However, I hit reserve at 125 miles! I was expecting to get closer to 200 miles from a full tank.
Stuck brake, etc - it doesn't seem like the bike is fighting rolling resistance
Carburation issues - needle jet on wrong setting, maybe wrong main jet size
Possible exhaust leak - The first time I rode the bike I left it on the side stand and saw some smoke coming from the left header/exhaust area. Sometimes at night I see what looks like thin wisps of white smoke in front of my headlight.
I was thinking of starting with adjusting the needle setting to run leaner. In the summer in DC I feel like the bike is a bit too eager to start up. Any guides to actually make this adjustment on a Dellorto PHF out there? Most of what I find is kind of general information on these carbs.
