What kind of water depth have you guys crossed with the TR650's. Has anyone found any issues? Will it chug along over the wheels?
It all depends on what you mean by "chug along"; our bikes took a deep dip on the COBDR, but I shure wouldn't want to stay in that stream any longer than I had to. Howsomever, there is this guy who goes by "Colebatch" if you really like to go swimming.........
By "chug along" I mean happily run for several hundred yards if necessary though about 2 1/2-maybe up to 3' of water. FWIW I had the same bike Colebach does. Well......I had a stock one. That bike had a very high air intake and it would chug along through water quite well. I don’t know if the TR's lower intake can do the same, or if it has a different venting that can cause issues on longer submerged runs.
After reading the water in swingarm thread I will most likely avoid any water crossings with the terra and save that for my other bikes
Avoiding water crossings right now in my area is not really an option. Unless I avoid ridding off pavement altogether. Everything is underwater.
So far I have not gone much deeper than the hubs/foot pegs. As of now I have been turning back on the deeper/longer stuff. I dont want to have this bike die in the middle when I am by myself, its too heavy. I started this thread in hoping to learn from others that may have done more. If I knew its no problem then I would be more comfortable pushing through some deeper areas solo.
From this picture you can see the relative throttle body position. As long as you keep any significant water out of the air filter box intake you should be fine. And it seems to me that the easy gauge would be to keep water out of your crotch. The engine itself has 2 breather hoses if I remember correctly. The crankcase breather is obvious on the right side of the engine going directly up to the airbox. There is another hose right in the middle of the valve cover. I forgot where this goes. I think it may have gone to the oil tank, more of a recirculation than breather. Make sure these hoses are sealed, and there are no oil leaks, or coolant leaks, and you should be fine.
I think it is a question of vent lines and air intake. Vent lines could be addressed/changed, for instance take the canister off and run vent lines higher up (I've not thought through all the details though).
Oooo, yeah, I forgot about the canister. If that valve opens while the canister bottom vent is under water then there could be a problem, maybe. Depends on how the canister is designed...it could have a method of preventing water from getting sucked into the system. If you still have the canister, you could unplug the valve electrical connection temporarily to be sure the system stays closed, I bet.
