Hey. i got an R1 too, well yamaha's litre race bike from 1987

i have a few tires go bad, even seen boob shape on the side wall once, these were all cheap tires though

 

That's an interesting explanation for a hard to diagnose tire imbalance.

When I had an air compressor at home (in the garage) I'd drain the tank of water every so often. It never had much as it was in the garage and humidity and temperature was rather constant, but still, it had some.

When I worked at a machine shop it was standard practice to drain the tank of water every so often, even though the air lines from the tank to the shop and equipment has water traps.

Even when I use the air at a gas station I will open the valve some to make sure there is no water in the air nozzle or hose. While I do not use gas station air often it is quite common for the initial blast of air out of the air nozzle to have water in it.

 

Thanks guys, I had the tires originally balanced a BMW/Porsche shop.

When the shake started I took the wheels off and took them in to a local Goodyear place.

I haven't hit any bad pot holes or large bumps.

I never have emptied my compressor tank, I guess it could have some water in them

I will do the screw driver test to see if they are out of round and then check the suspension before I take them back in.

Will let you know what I find

 

Macster nice looking bike and is that in it's own room in the house?

Mine goes in the basement every winter

 

The wider-width tires are nearly impossible to balance on a traditional spin balancer. The shop where Tire Rack sent my last set of tires tried 4 TIMES to get it right before I took the car back to the shop I normally use.

Once in a while, a tire will be produced incorrectly and need replacing - but a good tech with good equipment can do wonders.

 

Heh - I have never heard this description for a blistered tire before.

 

You are off a post or two. That's not my motorcycle. I have not owned a motorcycle since I sold the H-D Sportser back in 1974 or thereabouts. Oh, wait I did buy a couple of Yamaha dirt bikes right after I sold the Harley, but I got rid of them a few year later and it has been cars ever since.

 

Sorry Macster, meant soaringman

I think I will take it to the place I used to go to. It's on the other side of town and wanted to try some place closer, but I guess that wasn't worth it

 

Just had that bike in there over winter, did the clutch and painted the fairings. Fixed a dent in the tank.
The boob buldge on the tire was an old big front wheel drive car I got for free about 20 years ago, drove it to death

 

The car is nice, but when you want to rip it up the bike is the way to go.

Hoping the rebalance will take care of it.

 

I'm amazed this has stayed on topic for two whole pages. Front end shake...now there's a concept worth pondering.

 

Finally had a chance to get the tires rebalanced a reputable shop and the shake is gone.
Lesson learned!

 

Wow all that drama. Lol. Glad you got it resolved.

Just as a FYI to others reading this, some shops simply do not have the proper equipment to balance wheels that are greater than 10" wide but won't tell you. They'll just try to wing it and hope they get close enough. Make sure you take it to tire places that are used to working on cars with wide wheels.

 

I second that
