    Does any one know what this is? This bike has a wiseco programmer and drc lights but doesn't look like it's in one of those kits from what I'm seeing online. I'm new to these bikes and just bought it...other people already did some mods/deletes so I'm just going through things a bit and this one I never figured out.

    I buttoned the bike back up after messing with battery connections, heat shrinking and cleaning a few things, and re-routing the programmer up front and forgot to trace this any deeper.

    I guess this bike is pretty hooked up, things I probably would have done myself so good deal! It's still fun learning about the stuff but would have been nice to get a stock bike and done it all myself...I have a box of parts he took off but things are checking out good so far.

    Is there a problem if the fan runs more? As long as the bike is not boiling over, it is ok, right? There is a temp warning light, I have never seen it but I don’t regularly ride in hot conditions.

    Yeah fan running is fine. I'll notice mine starts running way more when the radiator is gummed up with dirt, maybe check that it's clear. I also notice that using engine ice makes the fan run a lot less. I have seen the light a few times before. It will pop on if you are going too slow on the freeway with a tail wind on a hot day, or if you are drafting behind a semi on a hot day. Or if you smash your water pump cover and don't notice, or if you bend your radiator so bad that the fan can't turn anymore. The light is letting you know you're too hot, if you see it you should shut it off and let it cool, or if within your power change your situation to make things cooler IE stop drafting a truck. The fan is a required part of the cooling system, as the bike only has 1 radiator, it is intended to run a lot more than on other bikes.

    Yeah, and at standstill its equal to oem :jack

    Its had to learn much from that unless we know what speed "lower speeds" covers. As the speed increases, so does the difference in flow compared to stock.
    Having said that, its not something that the average joe should worry about.

    I've had a translucent IMS on my 450 since 13' and it's still fine. Bike is garaged when not ridden though. Just bought the 3.1 IMS for the 250 and don't expect any problems.

    I believe part of the issue is that the plastic IMS tanks are permeable to gas fumes. The gasoline fumes will seep through the plastic and eventually will cause most (if not all) adhesives to fail at some point.

    I have put numerous decals on my IMS tanks and after awhile you can see bubbles form under them from the permeability issue.

    Interestingly enough, I had a Clark tank on my Beta 520 RR and that did not seem nearly as permeable. I had some decals on it with no bubbling and the other thing was when parked in an enclosed area for a few days the area did not smell like gasoline as much as it did with my WRR and it's IMS tank.

    I wonder if a plastic fuel tank repair epoxy would work? I wonder if it would sick to the metal, though

    Riding yesterday in the Danskin Mountains, about 25 miles due east of Boise ID. This USFS OHV area is over 60,000 acres with more than 150 miles of marked ATV and single-track trails accessible from 3 different trailheads. It's also beautiful in the springtime!

    In the photo below the SF Boise River is at the bottom of the deepest canyon, which you can see above my front fender. So basically this shot shows a river flowing through a canyon that's in a bigger canyon below a plateau in a valley between two mountain ranges.

    It's really sort of awesome. At least it is to me anyway. :ricky

    That's awesome. I've been all through the dirt roads around the south fork Boise River there in my 4Runner but never on the WRR. Idaho is a seriously underrated state!

    Thanks guys. I consider myself fortunate to live and ride here. The terrain in that photo will be even more beautiful in a few more weeks when spring greenup is in full swing.

    Here's a shot from May 10 last year:

    Shhh! My photos don't show all of the wolves, ticks, rattlesnakes, and rednecks. It's not safe to come here. Be sure to tell all your friends. LOL.
