Protecting the Crown
I need some advice. I'd like to protect the handle crown (that chuck of cast aluminum around the ignition switch that holds the handlebars) from getting anymore scratched up by my key chain, than it already is, while having it look neat. I tried duct tape and quite frankly that ain't so hot. I'd like to keep the price on the lower side rather than the higher side (say under $25). What do you all recommend? Regards, Henry S.

Re: Girth matters...Friction semi fluff
Greg According to CRC Handbook of Chemistry and Physics, 71st Ed. , pg 15-41, "The coefficient of friction between two surfaces is the ratio of the force required to move one over the other to the total force pressing the two together. If F is the force required to move one surface over the other and W, the force pressing the surfaces together, the coefficient of friction, u = F / W." Note: u is actually the Greek letter mu which I can't type in this format. Therefore the friction force is = coefficient of (static) friction X total force pressing the surfaces together (on a horizontal surface, the weight). The coefficient for rubber is given as 1 to 4.

Lake Placid, NY information
I plan to stay overnight in Lake Placid, NY and be able to walk from my hotel to the downtown area. I have downloaded a bunch of motels from the Internet, but don't know if they are in the main district, or if they want my first born for a nights stay. Does anyone out there have any knowledge of the area and can give me guidance? Ray

Re: Girth matters...
I agree with you, it is too dark inside a dog to read... But riddle me this--why do longer snow skis make you go downhill faster? Wouldn't more contact patch produce more friction and slow you down? Where is the "normal" force in your equation? When you spread the weight (a constant, at least before breakfast) over a larger surface area, you decrease the "normal" force--the force that multiplies the coefficient to get traction. I'm going to try the stock sizes my next set, even the 130 front (I'll just have to work out harder). I do believe the 180's flat spot quicker, at least here in Florida, where the cloverleafs are to few. I like the Azarro's pretty much, but they don't have a 130 front and I got the shakes back pretty early and they wander a bit over 120...

Re: Protecting the Crown
Henry send me your address and I will mail you one of the little foam sheets that I use. It is made by 3M and ~1/8" thick. I cut a hole for the keys and trimmed it a little. It has been working well for a couple years now. Another alternative would be some clear vinyl sheet like what is used for number backgrounds for dirt bikes (if it is available in clear it would look better than the foam material I use.)

Re: Protecting the Crown
Henry, I hate the scratches as well. So what I have done since my first bike is to have a soft key tag and only the bike key on that ring. Problem solved. But then you may say, what if I lose the key. I always have a spare hidden on it somewhere. Just don't tell anyone. I really can't understand those people who think they have to have all of their keys on one ring and then expect not to scratch stuff. My .02 Grant Henry wrote: I need some advice.

Tires
Thanks for the info on tires. I went out and purchased a 170/60ZR17 Michelin Macadam 90XR. I wanted a BT57, but it would have taken them to long to get it in. The front is still the 130 and will last this season. We will see how it lasts. It will get a work out this weekend approx 1200 miles. Oh ya, the Michelin has a cool tread too! Grant Gall
Suspension Settings
This question has also been asked before, so once again I am not trying to start another long thread. Is it the owners manual or the shop/service manual that has the settings backwards? Is for the front or the rear? Thanks, Grant Gall
Re: Protecting the Crown
The most simple solution is not to put any extra keys on your chain (joke) Another solution might be to store your keys in a small leather bag, only the contact key comes out and the keybag can hang in front of the crown.

Re: New Member
Welcome to the list. I put a Vance Hines SS2R on my GTS. The model made for the YZF750 slips on. The only modification I made was to secure a small metal plate the pipe with a hose clamp where the centerstand rubber stopper would contact the pipe itself (you can see what I mean by looking at the stock pipe). Some people on the list have just let the rubber piece rest against the pipe (I don't know how it handles the heat on long rides). I put a carbon fiber version on, but they make the pipe in SS too.
