Difference 98 & 99 YZF400?

Can anybody please tell me what the difference between the 98 YZF400 & the 99 400,I'm looking at buying one but can't see anything different,Surely yamaha changed something,But what :D Any known problems with them :)

Cheers.

If memory serves me I think they increased the size of the rod bearing in '99. I know there was a change in the counter balancer as well but I think that may have come later. Other than that I'm not sure there was much difference.

Cheers for that,Now i'm in the know :):D :D

I believe that the 98 had some problems with clutch baskets. I have a 98 but so far so good in 3 years use since I have had it.
