    I can buy a Bridgestone 110/90-19 front tire for half the price of a 100/90-19 from a local shop.
    Will it fit? Any comments or recommendations? Thanks :)

    You may have to run it with the fender off for it to fit? But...the fender on most models acts as somewhat of a fork brace to keep them from flexing.

    The 110/90 will be roughly 9mm taller than the stock tire. Have you got an extra 9mm under the fender?

    Stock was a 3.25-19, or a 90/90. The 100/90 would be the next "size up" I don't think you'll have room for a 110. If you do, it's gonna be close.

    And "D" is right about the fender; the stock Yamaha fender includes a nice beefy fork brace.

    the circumference of the tire might be 9 mm taller. but from the center point of the tire. half would be on top and half on bottom. so your only looking at 4.5 mm on the top. 4.5mm on the bottom

    a taller tire also means less rotations per speed. a slower speedometer would result.

    there are TONS of tires that can be had on the internet for cheaper then what you could buy locally. you shouldn't have any problems finding the stock size. you also shouldn't have any problems finding front tires as cheap as $35.

    youi might want to do research for customer reviews on those cheap tires though. last thing you want is an accident.

    around here. the cheapest tires available for my bike was $400. i can buy as cheap as $115 on the internet. front and rear.

    i ordered mine from cheapcycleparts.com. ordered on sunday and had them mounted on saturday.

    My '85 XJ700 had a 110/90 on it when I bought it. The PO swore it rode just fine, but the underside of the fender sure had a lot of shiny spots when I took it off. It had MAYBE 1/8" clearance to the fender when it was sitting, and I wasn't about to find out if it would expand 1/8" or more at speed.

    Thanks to all who replied.
    Had my XJ Guru over today who showed me the fender won't allow any extra,
    rides and steers really well now. I would have less steering control and likely rubbing.
    Bonus was that the front doesn't need changing. 8)
    I really appreciate the replies I received; assures me of a group of guys/gals to be linked up with.

    Really? How old is it? If over 6 years, it does need to be replaced; it's tubeless.

    tire is like new, less than2000 miles on it? only the slightest weather checking,
    Buddy sez because it's a Dunlop Hog Tire, should be OK for at least one more season. I usually lean to the side of caution, so will be buying a new one withing the next month (Bridgestone Spitfire to match rear). Thanks for the heads up.
    Also doing the brake hoses as they bulge a bit under heavy pressure; any advice as to rubber or braided ss? The difference in price seems so close I thought stainless is the way to go.
    Bike only has a total of 14000 miles on it, rides like new.
    Bought it as a "starter bike" after being away driving cages 20 years or so. 8)
    Fits my needs so well, I doubt going any bigger.

    I'd get stainless cuz they look cool! lol, no, I'd get them because of the "rot" aspect of rubber hoses.

    Stainless steel brake lines are the single biggest improvement you can make to the stock Yamaha brake.

    Tires have a date code on the sidewall; you can't go by how much tread they have or how they look.

    Have you disassembled the rear brake and inspected the shoes for delamination yet? If not, do that first. http://xjbikes.com/Forums/viewtopic/t=15874.html

    Also, keep in mind that the hoses are not the only 30 year old rubber parts in your brakes; the master cylinder and caliper(s) have rubber parts in them that also need to be replaced, for safety's sake. Motorcycle brakes are not something to take lightly.
