Ok, here's the deal.
I have a '92 750, and I was getting horrible gas mileage. The shops around here wanted to charge me a million bucks to look at it, so I decided to get the manual and take a crack at it myself. I took out the old plugs, and they were all loosely screwed in with black tips.
I put in new plugs (I'm proud of myself - the whole idea of removing a gas tank really freaked me out) and now I get better gas mileage, but I've noticed a few negative side effects.
1) The idle is lower, which should be a good thing, but now when coming to a stop light if I don't downshift perfectly, the bike will cut off on me. This kinda sucks if the light all of a sudden changes to green and there are cars behind you.
2) At first I didn't know what 'flat-spots' were. Now I do, because I have them. Mostly in the lower RPM range. It seems like if I have the throttle fully open or close to it that they kinda go away, but if I have the throttle partially open (like I do most of the time while riding) the flat spots are there.
3) Sputtering - low RPM's in low gears cause the bike to sputter. Like if I'm in 1st or 2nd gear getting ready to pull into a driveway or a parking spot.
Does anyone have any ideas?
Nothing was changed except the spark plugs, and all the wires were put back properly. I took the air cleaner out to inspect it, but I didn't change it.
Thanks for any help
