    Moose throttle cam and Steahly flywheel weight review

    Thanks for sharing, I've been looking into this. I have been recovering from surgery but getting close to being able ride again. Over the winter, I sold my 250f which is what I'm really used to. I also built a sweet '15 YZ250 so that's my new bike I'll be riding. It's not going to be nearly as predictable! Did you consider the G2 throttle tamer? Wonder what (if any) differences are between that and your moose?

    Help!! 250XC puking coolant!

    I'm back.... I replaced the piston & rings, base gasket and head o-rings, new reeds & reed cage. Second kick, bike fired right up and first kick thereafter. Did several heat cycles, bike seemed to run good, took it around the block....all good. Buddy picked it up, took it for a ride around and said it seemed ok. He took it out the following day and said it was blowing coolant out of the overflow and possibly mixing into the exhaust. Could this be caused by 1 of the 4 o-rings in the power valve being bad? I did not even open the power valve/exhaust valve on the front of the cylinder. The two covers on either side were very clean though. I'm scratching my head!
  3. Cool, i have an appointment coming up. I'll ask about getting one. Is there a model number/name that yours is?
  4. Hi DK, do they offer much impact protection or are they strictly a brace?
  5. Awesome man, glad your going strong post ACL. I'm hitting the legs hard, been making great progress. I'm going to continue to build up my legs plus add a brace. It's all gotta help, including the initial placebo effect [emoji41]
  6. Good to hear your response, thanks! That's what I'm afraid of with the Mobius, looks so hot!! Have you had the chance to "test" them out? Do they give you some added confidence that they will protect you if need be? I'm so used to the leatt dual Axis knee guards, really liked them for impact protection but it's definitely time to go for a brace!
  7. Really don't want to have to go through that looong downtime again so trying to find a solid brace. I found a deal on a POD K4 bought that and tried it on in the house, w/o boots on. Didn't like it at all. The pattella guard was very flimsy and can't imagine doing much. The whole thing didn't seem that good to me, despite the glowing reviews. The TLD's sound nice and are reasonably priced. Read the patella gurad isn't the best in the center but otherwise solid. Some said it was a little short. Anyone have experience with the TLD Catalyst? The runners up are: Alpinestars Fluid Tech Carbon, Alpinestar Fluid Pro, Leatt C-frame or MOBIUS X8.
  8. Damn man, sorry to hear that!! I haven't ridden since January when I went down and tore my ACL and meniscus. Had surgery in March, hoping to get back out soon! I know your non-physical pain. Speedy recovery!
  9. What happened Pat>>>?

    250 jetting database

    Just installed a Boyesen RAD valve and an FMF gnarley. Any recommendations for that set up? 2016 250XC.

    Help!! 250XC puking coolant!

    I thought that too. I asked my friend if he topped it off at any point recently and he said no. It was high so I sucked it out to the fins. It didn't spit out right away, but it did after taking it for a rip down the road. Actually quite a bit. The weird thing is, even after all this time it's been spewing, it doesn't look much lower! I'm sure its coolant too. I'm going to replace the head o-rings and the base gasket and hope for the best. I also tilted the bike over with the cap off to get any air bubbles out before all of this...

    Help!! 250XC puking coolant!

    Op back, pulled the power valve cover off and it's dry and looks fine. Pulled the water pump cover off and the impeller spins as it should. Pulled the head off, both o-rings looked ok. I'm left at a standstill here. I'm assuming the problem is the system is over pressurizing for some reason, but don't see any reason why. Anyone have any other suggestions?

    Help!! 250XC puking coolant!

    Makes sense and is what I originally thought would be the power valve. But what is very odd is that bottom picture, showing the PV breather tube, that tube has coolant shooting out of that! I'm assuming it's coolant. Man, at this point I don't know what to think. When I hit the gas, I have coolant shooting out of the right fitting (top picture) and that fitting has the radiator overflow tube going to it. When I hit the gas, I also see fluid going through the PV breather and getting shot out of the breather tube which is connected to the other fitting, on the left which can also be seen in the top pic.

    Help!! 250XC puking coolant!

    Ok, this should make things a bit easier! There are two tubes, one comes off the radiator overflow & the other is coming off what must be the water pump housing but would look like a power valve on any other bike. Both of those tubes connect into those plastic "relief fittings" mounted to the frame (see pic 2 for this). The tubes pop right off of those relief fittings and they're definitely there to spew out coolant. At least from the looks of it. They have a small notch cut out of them to allow the coolant to spit out. Tonight, I switched radiator caps & sucked out a little coolant so it's sitting lower in the radiators. Fired it up, didn't spew coolant at first like before but after going through the gears it was spewing. Guessing the water pump impeller or head gasket will be the next item to check....
