Thought I would update a bit on this. I bought a 98 ST2 about a month ago. It had a pretty bad dead spot at about 3900 rpm. From what I've read, this is fairly common and hard to fix completely.

Well, just got a new chain and it's amazing how much the dead spot has been minimized. Not sure the correlation here but it's night and day.

Bike just flipped 20,000 miles and I replaced the tires and chain and rear brake pads. Feels great.

Just fyi incase others are having a dead spot issue. I'm far from a mechanic, just posting my observation.

no doubt your bike will ''feel'' much better after a new chain is installed ,new tires etc . a new, properly adjusted chain with decent sprockets will do wonders for riding quality . i'm not surprised you notice the lean spot a lot less. however , the dammed 3900 lean spot, will remain. one of my bikes, an 2002 st2, had a bad case of the 3900 rpm lean spot and occasional backfiring . an fim 161 chip solved that. it also ran cooler .
enjoy your st .
