  1. He meant 80mL to 5L, which is about 62:1. Too much oil. You want about 62mL.
  2. This a big source of confusion. Octane in the US and Europe is not indicated at the pump in the same way. Europe posts RON at the pump, the US posts AKI, which is (RON + MON) / 2. The end result of all this confusion is that 93 octane is the US is about the equivalent of 98 octane in europe (again, talking about indicated octane at the pump). https://en.wikipedia.org/wiki/Octane_rating#Measurement_methods Ethanol is a different matter, but if it makes you feel any better, Ryan Young and all his riders run pump gas in their bikes, and I run it all mine.
  3. So I'm still not hugely bothered either way, but I did put ATF in the gearbox yesterday just to see how it felt after seeing this thread resurrected. Bike shifts the same (which is to say quite well), the clutch is a bit quicker (expected), but what was really noticeable was how much less cold start drag there was. I think I'll probably switch to ATF. I did a bunch of ATF research when I first bought the bike, and by the published specs, Mobil 1 Synthetic atf was nearly identical to the Castrol, so that's what I tried and will use.
  4. I stopped caring. I run silkolene comp gear, which is what I ran in the GasGas, and it was fantastic there. Same in the vertigo. Il probably switch to silkolene light in the winter.
  5. I'll ring it out a little. I change the plug pretty regularly.
  6. So I'm starting to notice that when the bike is warm, on starting it it wants to, and sometimes does, stall immediately after starting if you give it a bit of throttle. It acts like a lean bog from a carb bike. It seems to be less an issue if it gets a really good kick to restart it, and/or you immediately give it a blip as it's firing. Anyone else know what I'm talking about here, or am I special?
  7. Replaced oil seal, still weeps. Next suggestion? Maybe the sleeve?
  8. Oil out the exhaust is normal. Run it 80:1, but how much drool you see will come down to how well jetted the bike is, how hard you run it, and what premix you run. The best way to start it from cold is to turn on the gas and lay the bike on the ground until fuel starts to spill out the vent line. Pick it back up and it should start 1st or 2nd kick. As for the fan, generally they kick on pretty quickly, especially if it's at all warm. No idea where you are, but here it's presently in the high 20's, and the fan on mine will start running within 5 minutes or so. That's just with the bike idling.
  9. 110 pounds is going to be a huge selling point. Would love to try one of they turn up here...
  10. I use what looks like the usual hard plastic number plate, but it's flexible enough that you can put it on over the light, then you can just put a couple zip ties around it and the fork legs to ensure it doesn't go anywhere. Unfortunately I've only ever seen them at my dealer, and I have no idea where he gets them.
  11. The guy at the 'bike shop' not knowing is not indicative of truth. At its most obvious, Motul wouldn't produce two different oils if they were the 'same'. Empirically, any idiot can open a bottle of 800 and see: it's dyed red, and it's very thick. Open a bottle of 710 and it's dyed green, and it's a lot less viscous. Conveniently, Motul provide data on each oil: 710: https://s3-eu-west-1.amazonaws.com/motul-production2/images/product_descriptions/technical_data_sheets/78423/710_2T_TDS__28GB_29.pdf?1492017625 800: http://motul.speclube.com/wp-content/uploads/products/specifications/800_2TFactoryLine_OffRoad_8371_(GB).pdf Basically: 800: PROPERTIES Red coloured. Density at 20°C (68°F) ASTM D1298 0.911 Viscosity at 40°C (104°F) ASTM D445 120.2 mm²/s Viscosity at 100°C (212°F) ASTM D445 15.5 mm²/s Viscosity index ASTM D2270 135 Flash point ASTM D92 252°C / 485°F 710: PROPERTIES Color Visual Green Density at 20°C (68°F) ASTM D1298 0.862 Viscosity at 40°C (104°F) ASTM D445 46.4 mm²/s Viscosity at 100°C (212°F) ASTM D445 8.9 mm²/s Viscosity index ASTM D2270 175 Flash point ASTM D92 88°C / 190.4°F TBN ASTM D2896 2.15 mg KOH/g Which is to say, they aren't the same.
  12. I don't know what most people would mix a Sherco 50, but if it's like any other trials bike, it's 80:1. The problem isn't your mix ratio as much as it's the oil you're using. Motul 800 has one of the highest flash points you're going to find in a premix oil. It's made for guys on big bore enduro bikes going through the woods with the throttle pinned. Try Motul 710. Much better oil for a trials bike.
  13. Un caged roller bearings need grease to keep the rollers in. Don't wash the old stuff out with anything, just displace it all with new grease.
  14. To answer the question, about everyone around here with a GG runs that linkage guard. It's hard plastic.
