    Yes, distilled water if changing coolant type. Gives everything a good douching.

    Did a 4 day trip out to Michigan with my club. Wow, it's dirt bike heaven!! I think I saw 4 rocks the whole time out there. It was a nice change of pace from the New England rock gardens. Can't wait to go back. I didn't actually get many pics because we were to busy riding lol.

    On another note, on the first day I went down and somehow pinched the left side radiator inlet to the point that it wouldn't seal at the hose. I managed to get it to a slow drip but I couldn't seal it completely. Once we got back to our cabin I pulled it all apart and rounded the inlet back almost round but enough to seal. Unfortunately I also found a hole in the hose from the clamp where it got pinched. It was repaired enough to ride for another day but it's all coming apart now that I'm home.

    Does anyone have a protection solution for this area? I'm gonna order a Samco hose kit today but it seems that the area right at the inlet is exposed and pretty vulnerable.

    Start with a clean slate if your wallet allows.

    5EEE67C5-B2D3-4829-8F46-4F0A55333B94.jpeg Just did my rear Tuubless a second look. Hoping to get a good seal on the low pressure side.

    This is my 6th or 7th install over the years on various bikes. It’s usually a one shot install and done.

    This time I must have not had enough armor all distributed. Back on and doing the overnight sit

    Trying to get to BBB turkey run.

    90 Hrs and about to do the forks and shock. New seals on order.

    Did a kickass ride yesterday in Gifford Pinchot with my good buddies @Eldon @BajaDave. It was a long loop that got even longer when are escape road was riddled with washouts that eventually turned us around. If I had to guess I’d say I had 8-12oz of fuel left in my 3.1 acerbis tank on the TPI. It was a long day and we made it back to the truck about 30 minutes before the sun went down. 7F2E1B17-5107-4550-AD80-A2D72AAF1F41.jpeg

    One hell of a ride! Glad we made it out before dark. I really need to get a headlight mounted.

    Here's the washout that finally turned us around.

    Above pick of fuel level when we got back to the truck. There's less then what it appears because of the fin that protects the fuel line. 20190906_175556_HDR.jpg
    I had 97.1 miles on my trip odo.

    You guys rock! So that is about 33 mpg presuming the last 1/10 or so is not able to be picked up by the pump. Is your mountaintop photo location Hamilton Butte?

    Good eye that is Hamilton Butte. I had a little more fuel left than Lee but not much. It was about 70-75 miles of hard trail, 10-15 logging road connectors, and the rear was the pavement on FS23 back to the truck. I’m going to take the bike to the pump to fill it up and get exact mileage out of it.

    I missed out riding with my buds this weekend due to work and a back injury, so here's a pic from a ride a few weeks ago. I can't get over how amazing this 300 works!

    OK, so I changed out the block gasket - can't say yet if this was "the" problem but there is no way that thing was stopping the air from going between the big hole and the 2 little holes. (This is a 2018 bike, so I guess Mikuni just churns them out with this defect year after year...)

    I also reset my float height to 8.7 mm. It was previously much lower, like 5 or 6mm. If I have my upside-downs right, increasing this measurement should lower the level of fuel in the bowl, hopefully reducing waste and increasing mpg/range. (I do have the drain hose looped up also as JD recommends).

    That's a real bad gasket!!! And yes, the bigger the number for the float, the less fuel.
    What pilot were you running prior?
    I bet you'll be super rich now that you fixed the gasket and will need to drop a size or two.

    JD supplies/recommends a 30 pilot regardless of elevation (I have their needle kit).
    But you're right, according to them the main and clip I was running should have been rich, so as I was doing the new block gasket I went ahead and changed back to the recommended settings.

    The JD chart has a single setting for 5000-10000 feet (400 main jet). If that is real I would be delighted. I'd be 80% satisfied if I can just find one setting that is good for both the desert and alpine riding areas near Albuquerque, but even that is 5k to near 8k feet.

    I find that the 400 works well for me at lower front range spots (7-9k) with the red needle on 2.5. For high stuff (9-13k) I'm running a 390 and red needle on 2. I think a 400 would be pretty lean at 5k. For 5-8 I'd probably run a 410 and red needle on 3. I run non ethonal race gas. For pump gas I'd go one step richer everywhere to compensate for the corn.

    Fwiw the gasket in my 19 looked perfect. I still stuck a JD gasket in it since I had it apart.

    I don’t run a pipe guard on my bikes because I feel like it transfers the impact to the exhaust flange. This can cause a crack which is a bigger issue than a dented pipe. The flange protector and a hydro force pipe repair kit would be my suggestion.

    For a rear disc guard I run the bulletproof designs on my 300 and an SRT on my 501. Both work very well. If you ride a lot of gnarly rocks and roots the BPD swing arm guardis highly recommended. I almost broke my front mount off before installing one. My buddy snapped his rear tab off on a low side in Baja. $75 is a lot cheaper than a new swingarm. E5260125-73D7-4D55-9EA2-BE91F2F3C36C.jpeg
