    put something on and stay in that position.
    Went to Rick's Rendez-Vous last weekend. Had a great time, bike performed flawlessly while I was there. We did a 50/50 gravel/twisty pavement ride each day. There were times when I'd have liked a bit more power but I think I would have only gotten myself into trouble.

    The forks and the Ohlins rear shock were magnificent: the bike felt like it was on rails. I burned up my TKC a couple weeks ago getting back from Death Valley and had installed an Anakee, which worked well, but I wished for a TKC on the rear quite a few times when the gravel turned to clay or mud or a goat trail.


    It rained every day and was quite muddy and slimey in spots. On the way home I was pushing 75mph for about 10 hours. After stopping for fuel a couple of local yabbos were having a chat and blocking the exit, causing my bike to idle for a minute or so, and my temp light came on. I got it into the wind and kept the RPMs down to 4000, and it went off quickly, but then weaving through the neighbourhood and stopping at the signs, my temp light came on again.

    I realised that the TKC has thrown a pitload of crud up onto the radiator, packing it in a couple places, and my fan is stuffed-- can't even spin it by hand.

    So a new fan is in order and a good scrubbing of the radiator (and the bike, too.) And I'll drop the oil. It only has 1900 miles on it in 4 days, but it's regular dino oil and clearly has been heat stressed. I'll also change the coolant out since it was last done (or not) by the PO.

    Those fans are expensive!






    Packed and ready to roll. I discovered on the ride to work the morning before that I had no headlamp (aside from the small marker bulb) and my brake light was stuck. Then I had no tail light at all, then it was full bright...? I new headlamp went in and the rear brake light switch adjusted and a new tail lamp installed. Two things in play back there.

    Bike covered in slop front to back. Those of us with TKC's really covered our own headlamps with hogshyte. Made me think about a new front fender. I have a low Dakar fender just sitting in the garage.

    It was gloomy but the rain packed the gravel down. It also made red clay ice in some places. Spirits were high, though.

    There was another F650GS out there with a YZ450 fork on it. And a couple other F650's that were stock. It was good times!

    Changing out the beak for a "real" dirt bike style fender will solve the issue of mud getting thrown up onto your headlamp/windshield/face. The low Dakar fender runs the risk of getting clogged with mud when you get into the slop.

    Interestingly, I've noticed less mud in the radiator as well, after switching out my front fender. I'm running a Polisport UFX free-flow fender, with vents on the backside. But it seems to catch more of the crud than the long extension on the stock fender did.

    For those wanting a stabilizer its really easy. You need a BRP or scotts sub mount for a BRP or scotts tipple clmap that would go on an 05wr450 or older. BRP will know which one it is. You need a BRP or scotts top clamp. Then you need a 2011 yz250F sub mounts stem mount. YOu need to weld on a cross bar between the frame. The 250F mount goes on the stem and uses a different nut. Here are some pics. It worked great.

    Be careful when washing the radiator, it's pretty fragile. I'd try removing it from the bike and washing it from the rear first. Make sure there aren't any small stones left and use a small piece of foam when reinstalling it (between the frame and the radiator, this is where small stones/ large grains of sand will lodge and effectivly grind a hole in the radiator)

    Don't looking to cause trouble, but I'd keep a real keen eye on that warning light from now on. It it ever lights up again, get to the bottom om it.
    Having had mine overheat and all the shit that followed I wish I'd properly solved the problem right away instead of taking the "easy" route 2 two times first (where I "just" replaced the headgasket)

    Good luck :thumb

    was wondering if else has swapped their front fender for an off road fender?

    i used cycra fender made for the yamaha forks. however the back part of the fender was rubbing on the frame so i cut it off.

    do any of you know a way to avoid cutting off the backside of the fender ? are there any that turn down at a sharper angle in the back ?

    thanks.

    trying to keep the mud out of the radiator.
    if i use a motard fender wont the mud still get into the radiator?


    also, i noticed that switching to the 18" rear caused some bad mojo with the center stand. bike wants to fall forward when front tire is removed. anyone else experience this phenomenon ?

    You could hack on the old fender from the F650 I suppose.

    I put about 1/2" of spacers between my Acerbis fender and lower triple to keep the back side from hitting the frame. It hasn't given me any problems this way.

    My mate Dennis, Inglsman on the forum, dropped his bike off for me to do his YZ fork up grade and raise the rear.

    I decided to start at the rear.
    Rear wheel off.
    Linkage bolts out and the swing arm didn't drop down on its own

    The clicking and cracking is from the bearings :eek1
