I just bought my second Evo. It is a 94 Ultra. it seems to have a wag maybe it can be called a wobble at flat level cruising. 55 mph and up. Any ideas.

 

How are the tires?

 

Probably doesn't have spokes, but I've seen it when they are loose.
Otherwise, it could be worn swingarm bushings, or wheel bearings.

 

Tires, bushings, neck bearings, wheel bearings, cleve blocks.......

 

As already suggested, check your tyres, for wear and date, but especially for brand and pressures. A few brands use different pressures to the owners manual, so let us know what they are. By all means also check the wheel bearings, but I'm more inclined to suspect the swingarm bushings. They are of composite construction and if original are way past replacement. Best IMHO to replace them with a solid bushing kit.

 

Brand new tires, the wheel bearings are good just did them (.003) Swing are felt solid when I had it all apart. Front to rear alignment maybe?

 

Alignment is certainly a possibility. What tyres do you have?

 

Tires are Shinko 777HD. Pressure is 49psi on side of tire. That's what I have them at.

 

Those pressures are too hard, unless you are exceptionally heavy! They are the max permissible that should be used, not a universal recommendation. It is also significant that they are only there to meet a US regulation, as no other country requires them! Check the Shinko website, to see if they recommend pressures for your bike, if not use the recommended pressures in your owners manual.

 

Check your engine and transmission mounting as well. Not long ago, I was having a handling problem. Loose/sheared mounting bolts....got replaced and tightened.

Rides like new again
