carb Jet settings
as far as the larger jet size does that go on the inside cyl numbers 2 and 3 and the outside cylers 1 and 4 get the smaller size. Why would the hotter cyls need more gas?Tags: None

I think you might have it backwards. The outer cyls need more gas because the inner two burn the fuel hotter and more effeciently (maybe???). All I know is that the outer two cyls should have a little bit higher vacumm during a carb synch- I always assumed that was why.Currently bikeless

the inner two cylinders will be slightly richer to stave off detonation. The cooler outter cylinders can run a leaner mixture without detonating.You'd have to be crazy to be sane in this world -Nero

So if the previous owner had the jets switched (which is what I found) could this cause a problem machanicaly ie valves burning

Some models come with a step richer mains in the middle cylinders to help them run cooler.
If yours were reversed, then it's possible you could burn the valves. The mains supply fuel at 3/4 throttle and more. So the bike would have had to been ridden at high speeds for a while to burn the valves. Possible, but I would suspect the tappet clearances are too tight before blaming the main jetting.And on the seventh day,after resting from all that he had done,God went for a ride on his GS!
Upon seeing that it was good, he went out again on his ZX14! But just a little bit faster!
