Beware all 13 redhead owners. Blown hose & more

[bigmo]

Without sounding like a jerk - did you not smell the coolant? A 1/4 ounce comes out of mine and I cannot smell anything else for an hour. Were you running something special with no odor? I have to think that the smell would have been atrocious. I also would have thought you could have felt the bike get hot - my four strokes that ran hot could really be felt between the legs. That being said my 449 is so hot it feels like a nuke generator as-is - so maybe the 310 is like that too.

I can offer that the CRF250X is a uber-solid race platform. If I did not travel out west, it would still be my woods bike of choice. Int he moutains it just did not have enough spunk. If Honda could release that bike as a 290CC with EFI they could outsell KTM! That bike is uber-quiet, still light by today's standards and suspended better than ANY WP bike I have ever owned no matter how much money I threw at KTMs...

Prts are cheap, the motor is rock solid and the bike can everything exceptionally well - sans going above 8000 feet - it doesnt like height whatsoever!

The 250x also likes to suck valves pretty quick. Good bikes though.

Was running ZipTy waterless coolant. Don't think it has a smell to it nor does it create steam. It wouldn't have mattered because I couldn't smell anything anyways. Went to urgent care in Laughlin on Thursday because my ears, throat and sinuses were killing me. Felt like shit the night before we left on trip. Found out I had an ear infection and my ears had a lot of fluid in em from my sinuses that were flowing like a waterfall!! Going over all the mountain passes felt great!! Great weekend!!
I've owned a 449 and my legs always felt like they were being bar b qued when riding. I was wearing new Moose Sahara gear and to be honest I didn't really notice the heat while riding. I was in race mode at the time and was concentrating on not hitting a cactus again. Came in after first loop and spent 20 minutes pulling cactus needles out of my left thigh. One of my fellow racers, whom I was trying to pass, decided to stop and let me by. That's great except he stopped next to a cactus. It was either hit him or hit cactus. Another bright spot to the weekend!

I just had mine tore out new and Pro-X in all around - had zero issues and had LONG intervals. It was my first shim bucket bike in a long time (had screw types) and thought it was a PITA, but got used to it and gained an appreciation for the precision of the shim buckets. I got fast to the point of 45 mins to adjust. Rocky Mountain sold a very inexpensive shim kit to have all the shims on hand.

The steel valves gave up no discernible power (none that I could feel at all) and gave 10x the adjustment life. Titanium was dumb-dumb-dumb on Honda's part - all about that marketing HP number. Stupid...

A guy I ride with has a 2005 he bought new and he finally installed the Kibble White steel valves this winter. He shoud be happier with those from the sounds of it. His is a 290 BTW. He loves it.

Took bike out of truck and into garage this afternoon. Bike started right up. From what I understand if cams are ok the motor is good. Here's pics of clutch side exhaust and intake cam. I can't tell if their good or not. There's no metal up top which is a good sign. Anyone know if water pump pump impeller is plastic or metal. If it's plastic it has to be melted. If this motor is good to go, I can only thank Mobil 1 0/40w oil. There's no reason this bike should be running. Motor only had a little bit of water in there. Go out and buy some Mobil 1.

Hopefully you are ok. I had the same hose burst at the end of one of my rides. I purchased the Zip Ty spacer kit and placed the metal clamp just under the screw that rubbed the hose.

 

[fire1998]

Wrong part of hose. The zipty spacer saves the hose that is attaached to waterpump. Mine was rubbing on head by thermostat. Check it.

WOW! You got your TXC310R to run 10 hours...you beat me. Less than 10 hours and my bike crapped out. Hydro-locked 3 times and won't start or run at this point. Dealer is scratching his head on how to fix this problem (has replaced ECU, temp sensor, fuel injector...and more at my cost). Bike only has 30 day warranty so I am sh*t out of luck. Meanwhile I haven't had a bike in over 1 month. I am making calls to trade it in for another brand, but so far none of the dealers wants this bike.

I hear you , these bikes are quickly building a reputation for being grenades .

I know this is hind sight, but racing or not, we do not run thermostats on these bikes. They run extremely hot and any flow restrictions is a big no-no. If you own a 310, no thermostat and XF is your friend. M1 0W40 is really great oil and for racing I add one ounce of ADDP on top of it.

Active Duty Dental Program?

The '13 models and '14's have a thermostat (left) and a temp sensor (right) for the fan. Was about to pull the plug on the Samcos as they allow the thermostat but are not cut to allow the fan sensor on the '13/'14. So on a model '13/'14 what hoses would be recommended and should one then cut the new hoses to accommodate the fan sensor and then splice the hoses with an interconnect for the missing thermostat? Not changing a thing yet without a proper hose for these models that accommodate the fan as needed. Appreciate any info, correct info If I am mistaken.

 

[CCP]

Zinc additive?

 

[Motosportz]

ZDDP

Which i thought was bad for wet clutches.

 

[robertaccio]

you simply cut the hose to adjust for the fan thermostat.
PS For inspection/note: even after I added the ZipTy tank spacers I got another tiny chafe leak at the coolant pump spigot, with a full fuel load that lower tank portion moves around and can still make contact, I added a slit hose as a doubler, just like you see on my lower hose in this photo. In this photo you can even see the spigot hose area has been chafed on the CV4 logo (this is before the tank spacers were added). This machine requires lots of race/ride prep and close inspection and solid mods to bullet proof it for tough conditions.
Another note: my first thermosat equipped dirtbike was my KTM250EXC, I left the housing (there were no real hose kits then) installed but removed the thermostat, one less thing to fail under race conditions, imagine if your T-stat fails closed, its happened on some of my older cars, nogo on a race bike!! get it off. I wanted the thermostat removed asap on my TE310 and also on my TXC310R, the CV4 hose kits took care of that..

 

[Tinken]

Zinc additive?

Zinc would be ZDDP, but ADDP is antimony, used by NASA for high pressure applications. this forms a thin skin over the metal which protects it in the event of accidental contact. You may purchase addp under the brand name Maxilube.

 

[Motosportz]

addp under the brand name Maxilube.

Can you provide a link? When I google it I find "personal lubricants" which sound good for the wife but maybe not my bike.

 

[robertaccio]

Its in my TXC310R per ZipTy Racing recommendation.

Oh btw Robert, I took your SS filter you gave me and installed it in Ty's personal 310 yesterday along with our drain back kit. Works perfectly and has 3mm gap for oil to flow by.
