  1. So I bought a used 2014 Honda CRF450R for my son. Replaced engine oil and gear oil before our first ride, only to discover gear oil was milky and dark grey coming out of the bike. Engine oil was dirty, but fine. Called local shop to ask if the milky grey transmission oil was evidence of coolant in the oil, and they said maybe: change the oil out, go ride for a few hours, and empty oil out again. If oil is just a little grey colored after riding, that can be OK: the steel clutch plates can turn the gear oil a bit grey in color. If it's milky again, they said I've got coolant in the oil -- and first suspect is water pump shaft/bearings/seal. SO, I follow their advice, used Honda oils, and we go for a first ride. 80 degree weather, and got into some gnarly rocks in a canyon (unexpected) at about the two hour mark. Slow speed 1st gear stuff, lots of clutch work to get through some tough sections with boulders, and my son stops and says that clutch seems grabby and he's having a tough time. I get on the bike myself to get it through the section, and see if in fact it's not behaving well, and sure enough the clutch is kinda grabby and seems a little finicky as I try to get it out. Hmmm. Once out, I stop and inspect: bike is dripping same grey colored milky oil through the tranny breather tube onto the dirt. Bike is hot, which could be why clutch is acting up. However, nothing coming out of water pump weep hole, and no coolant drip. We decide to let the bikes cool down, and after enough time I open radiator cap and sure enough the coolant is low, not even showing coolant at top of fins. I assume there's a coolant leak mixing into the transmission oil, so we ease the bikes back to the trailer and head home. Here's where it gets interesting. Tonite I drained both the engine oil and transmission oil. Both looked completely fine, fresh and barely dirty. No milky grey color gear oil, not milky at all. Inspected clutch plates, they look fine too. I then pulled the water pump cover and the propeller off, and while I didn't pull the engine case off and inspect the water pump shaft (because kick start lever was frozen on and I couldn't get off), shaft did not appear loose to me. It could be leaking coolant through seals, I suppose - but if it was, the gear oil would be milky again (right?)... which it wasn't. So - I've concluded, correctly or incorrectly, that the milky oil from the engine case breather tube (emptying out below swing arm) that was dropping milky oil on the ground in the canyon was residue leftover from old oil getting pushed through the tube. I've assumed this because new tranny oil was clean and not milky or grey colored. I'm not sure where else it would have come from, since both engine oil and transmission oil were like new... but I'm scratching my head as to where the coolant went, why the loss. I checked the coolant level before we rode, and it was just above the radiator fins before we started, but was below fins after our ride. Anyone have suggestions or ideas? I'm not sure where to go from here... thanks for any advice you can offer. (I'm not much of a mechanic, pretty inexperienced, and maybe the problem is obvious to those with more experience).
  2. I just picked up a 1998 YZ250 and I am changing all the fluids. In the Gear box can I use 10w30 Motorcycle oil? I have a bottle left over from a 4 stroke I had. I read some have used type F ATF, any recommendations on that?
  3. Hey guys. I have a CR250R 2007 and I’m asking what the recommended/best transmission oil for it is? If you’s could hope that’ll be great, thank you
  4. Bike is a 1999 Suzuki RM125. I had the crankshaft rebuilt, so during the install I had put in new crank bearings, new crank seals, new case gasket, new reeds, and a new top end. I also cleaned the carb and put in the recommended jets for my exhaust and elevation/temperature. I run 32:1 fuel mix. I also put in a new primary gear, which is what contacts the oil seal. I put axle grease into the seal before inserting the primary gear. The bike smokes more than it should, and I'm pretty sure the cause is that transmission oil is leaking into the crankshaft area and eventually getting into the cylinder. I would top off the oil and check the level with the little bolt on the side of the clutch cover. After a while of riding I would take the bolt out and I would have to tip the bike quite a bit for anything to come out. I don't understand why it could leak. I also topped off the coolant, and the level stayed the same, so that's not leaking. Do you think its still getting in through the seal? If not, where could it get in from? There was quite a discussion as to the orientation of the seal itself here, but since that post I have installed a new seal with spring side out (which is different than most bikes, but I think that's what the manual says).
  5. The owners manual says to run 15W-50 but I have seen that a lot of people run 10W-40 for transmission oil in a ktm 2 stroke. Which is better
