First ride - Minor? Issues

[almarconi]

May I make a suggestion?

Adjust your valves BEFORE doing the carburetors. Once your valves are set, set your idle mixture and then vacuum sync the carburetors.

This fuel filter is a paper media filter made for automotive use. I believe it's for carb'ed vehicles. Think a restriction would cause that kind of problem? It doesn't complain at all when I gwonch on it in first and second.

Have you tried running without the fuel filter? Automotive filters are designed to be used with a fair amount of pressure. Even the lowliest of engine driven mechanical automotive fuel pumps puts out a LOT more pressure than a gravity feed motorcycle system. The air bubbles you mentioned aren't very encouraging either. Maybe a loose connection that's allowing air in, but not loose enough to allow fluid to dribble. Or maybe an old hose that's decomposed enough to become air permeable?

Lots O good advice, just hammering on what has already been suggested. Adjust valves, synch carbs, remove the extra filter. Light grease on the cable not the heavy wheel bearing stuff especially if it gets cold where you are. a $2.00 can of spray lithium grease works well for tach speedo clutch choke, any and all cables. Keep telling us how it's going.

Thanks ggGary. Concise is nice.

White lithium grease for the cables, I'll replace the filter with a gravity feed one. The one I got was only temporary anyway.

Do you all think valve adjustment and carb sync would explain the running issues?

Anyway, now I just have to wait and see what changes when I do something.

I'll post back.

PS the fuel line is all new.

just my 2 cents but when tracking troubles remove anything that wasn't stock on the bike. Try it without the "extra" fuel filter then if it still leans out you know "that" wasn't it. I don't think anyone mentioned blocked gas tank vent which is a possibility in this situation also. Best O luck to you!

It is a process of eliminating variables valve adjustment, carb synch, and on some models intake O-rings are known trouble creators there is no gain in looking for other solutions til the obvious ones are known to NOT be the problem.

Yamaha has a filter for it's cruisers that work nicely on these bikes. It's fairly large so extra fuel line might have to be used to eliminate kinks. Having trashed the first set of carbs a friend rebuilt for me from a rusty tank, I will go against the crowd and say use one. http://picasaweb.google.com/lh/photo...eat=directlink
