I rode it just a bit yesterday, and other than the blown fork seal and possibly a tight spot on the chain, all seemed well. But it just wanted to fall into the corners, enough that it was unsettling.
I didn't check the rear shock for air, but the forks are at 0 psi.
Is this just the 16" and 18" wheel size combo, or should I be looking for other issues.
Tire pressures were 36F/42R
thanks

How old/how many miles on the tires?

that's not normal.
Tires are resonably new, the rear is within a few 100 miles, the front has I think significantly more. Profile and tread look fine.
Feels a lot like the '90 CBR1000 did when I got it back from the shop with 63 lbs of air in the front tire.

What are the tire sizes? The front could have a 130 on it which would make it extremely narrow on the rim. When good rubber started to disappear for the 16" fronts, people tried putting on tires that fit early CBR900RR's. A 130 works on a 3.5" but not a 2.5". It sounds front tire related to me even if it's the right size. Some tire Mfg's roll off differently than others. Bias or radial on there now?

Bridgestone BT 45's, so I doubt it's in 900RR sizes.
This is 1976Mike's old bike, in case he's lurking.

That's the correct pressure for both the front and rear - any added pressure just makes things even worse. These bikes do kind of fall into corners with the stock suspension, so maybe it's just something you need to get used to. I'd ride it for a while and see what happens. If you still think there might be something wrong you can start digging into it then.

Probably the best thing to do. Nothing seems out of place, and it was a rider before I got it. it just steers much quicker than I would have expected, and seems almost unstable once it starts in.
My VFR400R is slow steering compared to this.

I felt the same way with my old 700, and the difference between the origional wheels and the F2 wheels on my 1KR.
It used to fall into the corner and not inspire confidence. Now, it goes in harder but feels more stable.
I always found that WFO throttle helped stabilize the bike. :fing02:
