I have an interment handle bar shake on my Honda/CSC trike. History; never a problem for many thousands of miles. Last summer before taking an extended trip I installed a new front tire. No issues for about 3,000 miles but at one point at highway speed the bike started to wobble to the point I thought I might have a flat tire (I didn't). Rode the next 1,000 miles with concerned caution.
The steering head bearings were slightly loose and had a bit of a notch. Had them replaced. No improvement! I had some worn A-arm bushings and a worn hime-joint so had that all replaced. No improvement! Periodic wobble still there. Although the bike does feel a bit tighter.
Today I rode on a new section of freeway that had the small grooves. Scary wobble! Thinking back, my first wobble last summer was on new grooved roadway as well.
What I'm thinking now is front tire. Inspecting the tire I don't see anything unusual except, something that looks like a pencil line around the circumference about 1/4 inch off center. It doesn't feel cut or grooved. It's just a line! Perhaps some internal belt separation that doesn't like grooved pavement? Long ago I had a 2-wheeler that did suffer from tire tread separation and it, at times, handled like a pregnant duck.
I'm picky about tire pressures and check/adjust it probably more than most. So, tonight I ordered a new front tire. Hoping this resolves the wobbles. I will stay off freeways until it is mounted.
Any thoughts or suggestions? Again, this issue only started after about 3,000 miles on a new tire. Thanks..... Jim
