Grunting And Thumping

My daily rider V30 has developed a strange intermittent behavior that so far I have not been able to diagnose. I'm still working on it, but I thought I'd sound off and see if anyone else has any ideas.

There is a rhythmic thumping sensation, which I feel in my footpegs rather than hear, the appears when I'm accelerating out of a turn. I have also noticed it when accelerating in the straightaway.

The thumping seems to be tied to ground speed, not tachometer.

It usually does not appear when I'm traveling at higher speeds, nor when I'm traveling at a steady pace. Only when accelerating moderately. Heavy acceleration does not produce this thumping.

The tires are fine, no tread separation, no defects. The chain seems fine, is well lubed, and rear sprocket is not bent. Rear wheel alignment is okay.

Rear tire, chain and sprocket are all on my list to replace this winter.

I'd entertain any thoughts or suggestions (except "go buy an FJR"). My guess is a worn or sticking link in the chain, which is not apparent to me with the chain on the bike. My other guess would be an emerging tire problem, also not visible to the naked eye.

I will perhaps know the answer better when the snow falls and I replace the rear tire and chain. Meanwhile, if there are other suggestions it might point me in a direction that leads me to a solution....

This Affliction

This curse, this motorcycle bug, still has hold of me.

41 degrees and 50% chance of rain today greet me when I arise, and I don my gear anyway, and ride to the office.

My speedometer cable squeals from 20 mph to 60 mph for a few miles, til things warm up. Wind gusts of 20 mph try to sneak into my leather. My only vulnerable spot is my throat, which is open to the air.

I arrive dry, anyway, if not warm. Fingers are a little stiff from the cold. Could use better gloves.

My buddy, who sits next to me, didn't ride his BMW R1150R today. I chide him because he even has heated gloves. "If I had hundred dollar heated gloves by Gawd I'd use em."

"You could just drive your car," he said.

"Hadn't even occurred to me," I said.

This evening's ride home catches me in a wintery rain when I'm just 10 miles out.

No sense donning the rain suit for just 10 miles.

My wife kindly wipes my leathers down for me when I arrive home. Bike just drips dry in the garage.

"Done for the season?" she asks, though she knows the answer.

"Hell, no! There's no rain in the forecast for tomorrow," I reply. "And you know, aside from my throat, I'm not even cold or wet."

She gave me a sideward glance. Maybe she just had an idea of what to get me for my birthday, next month.

Ride on!

Kid's Gear

Contact me offlist if you have some kid's gear you'd be willing to sell me cheap

My son is Age 6 and is Ready To Ride Pillion. Bought a HJC CL14Y helmet for him, matches his daddy's CL14. But he has no jacket nor pants.

I don't feel right wearing my super suit, "all the gear all the time" but hauling my own flesh-and-blood wearing jeans, flannel shirt, no gloves, tennis shoes, and a full-face helmet. Just doesn't seem right.

I'm fortunate to have a wife who rides and who'll let the kids ride too. Most of my MC buddies at work have wives (or ex-wives) who wouldn't ride, wouldn't let the kids ride.

Don't have much money ( I am a maggot! ) but if you've got some kids gear that you're not using anymore maybe we can take it off your hands and give you something for it.

Also have a 3 year old daughter who will be riding soon too.

Here's hoping. .... thanks ...
