Today on the ride I set the idle to less than 1000rpm (wouldn't quite hold an idle) deliberately to make it as small a factor as possible. There's still a bit of bucking though its quite tolerable, so if I cannot improve it, I'm not unhappy.
So, to set up: stock jets throughout and also stock float height. Not sure if these are Suzuki float valves or not. I've found that I have to have the fuel screw out only 1/4 turn and not the 3/4 turn out in the manual, or the off-idle is too rich. At 1/4 turn its perfect. I'm told if you're at one extreme or another on a fuel or air screw its worth testing the next pilot jet size so I have some one-down 42.5 Mikunis is needed, but haven't installed these. Airbox was recently taken out, filter cleaned and oiled, and installed with good foam seals and foam was installed under the airbox covers, so I feel thats not an issue. Timing is stock, Marcel elec ignition.
The carbs have been tapped for pilot air restriction jets and I have sets of 3 sizes: 0.9mm, 0.8mm and 0.5mm.
I was thinking of trying the 0.5mm as these should be at worst, too small but at least will test if PAR jets will make any difference.
Other than 'stop worrying about it', any advice? I'm an inveterate tinkerer rather than worried
One final bit of info which I can't get my head around. If when hot I set the master idle to 1000rpm, then ride it, on returning home its almost always higher OR lower but rarely 1000 any longer. Most times I have to turn it down or up almost a half turn on the master and I cannot work out WTH is happening here. I mention as it might be relevant since failure to get the butterflies closed when coasting is a major cause of bucking.
Cheers,
Mike
) as I haven't had time to fit the anti-surge jets but this was identified by Suzuki back in 77 and this was their solution. Even then, they admitted it would "reduce" the problem! Kev
