I agree with checking the tire- I’m running tapered bearings in both 1100s (and torqued exactly the same) and only had the 94 with a decel wobble with a Shinko tire up front- didn’t happen with any other tire (and with roller bearings as well on that bike)- new tapered bearings on the 94 and 2000 in the past year (2000 had them for years but I figured I’d swap them both out based on age and mileage) and Shinko tire up front = wobble again, so I won’t be using a Shinko up front in the future (but the rear tire is wearing very well- also a Shinko). No Shinkos on the 2000 and never had a wobble
