Hi All I've used stock tires for the life of my A1 with good success. 6 to 7000 kms per tire. However just ordered a set of Avon Gripsters $120 front and $150 rear respectfully ( Can. $$'s) from the local shop in Corner Brook Nfld. Good reviews on the list[ why I ordered them to begin with] A couple of Questions however; for Gripster users: How do you find them in the dirt? What rating are they 60/40.... 80/20?

My Dunlops were down to a slick center band after 2300 miles (the side knobs still had a bit of life). I recently changed to the Avon Gripsters and find a marked difference in the on road handling. The gripsters have a much less squared off profile than the Dunlops so the bike falls into turns with much less effort. I found myself oversteering for the first 50 miles or so. I have scrubbed them in now and find them to grip just as well as the Dunlops on the hairpins. I have not tried them out on the dirt. I had no grip complaints with the standard Dunlops just that they seemed a little too soft for my style of riding. I will report how the Avons stand up to my local abrasive canyon roads.

Nothing engine threatening here.

Seems right of me; I'd leave RE as is.

In my experience they also tighten though usually not as much

Not unusual. The more miles the less shim valves tighten. My last check 30k miles didn't have to change anything. The one before 18k changed three shims.

No way , It was just slightly off.

I believe it's only checked at the factory and then at 500k.

Nada to be sorry about; Fire away. Bogdan
