Are you sure its slack in the midrange? The BV motor likes to rev more than my MV might give the impression its flat when its not.
UPDATEi got a new plunger for the left side carb and kaboom! almost all better! much faster, better pick up through the gears, still a bit iffy at traffic speed riding but much better overall. Also, as happens with 32 year old bikes the right side carb started playing up :( oh well.I moved the needle clip to the bottom position, and left the 65 pilot in place. it is a still a teeny bit rich, as evidenced by the carbon build up on the pipes but i think that is the float bowl heights that i have not yet checked.I will keep at it. thanks heaps. really appreciated
Furbo, do you happen to know if there are header lile the one you mentioned (with the upper crossover) that will work with the factory pipe types?
Bump.Are you running an airbox?What upgraded pipes are you running?I'd love a list of jet recipes for my LM V...
Well,we've no idea what your intake system is, or your exhaust, but on my own LM V (same engine) I ran a set up similar to Eds and Guzziology, K&N's, and most importantly a Bub Hyper system exhaust. Moving the cross over up nearer the heads REALLY fattened the midrange.
My Mark IV has been running rich on the left side for a long time as well, and I haven't been able to find the problem. It's had a new carb kit, new choke plungers, the Ed Milch recipe, pumpers disconnected, new manifold rubbers - you name it. The right side has had the same attention lavished on it as well, but the RHS plug doesn't foul. It's running pod filters.I had a Dyna sensor die a couple of weeks back, and recently installed heated grips which stopped working after ten minutes. Worked out that the controller shut it down because it didn't like the power supply it was getting, which leads me to thinking it may not be a carbie issue but a charging / ignition issue ( but still dont know why only the LHS fouls plugs). Maybe timing is horribly wrong LHS ? My next job, which I dont look forward to, is to go through the charging / ignition system from alternator to plugs to see if I find anything. Any suggestions appreciated !Bazil
Hey Ben i had some problems with chokes some years ago and decided to remove them altogether. In our climate you don't need chokes.
