449/511 Breather hose mod

Not sure but I think we are on the right path thanks to you. "Tinken " I' m going for big breather, 1400cc oil and XF coolant.

I think you may be on to something there...

Damn you and your evans coolants! Glycol is the devil incarnate on tarmac tracks, would be nice to run it but alas

I know ethylene glycol is illegal on your track, hell you can't even run it on the motocross tracks here. But is propylene glycol illegal too?

I think instead of running a oil cooler on the left side of your engine, you should install an overflow tank and think about a second Spal fan.

Letter of the law (so to speak) says water only. I run motul mocool which is glycol free as my SMR serves as a street/track bike and I'm too lazy to continually change out coolant.

I have a motion pro coolant recovery thing which I'm looking at sticking behind the headlight shroud now I've removed the headlight for the track. Haven't tested if it'll even fit yet. A 2nd fan would be nice but so far even in over 35C air temps the bike's never overheated, although it spits some coolant if left idling for too long. I need to check the fan connections as I never see it spin up *shrug*

I took my te out on the tarmac today and even with the high speeds I was going up the highway, the fan was running hard

Where are the relay's and connectors for the temp sensor and fans? I'll have a look and make sure they're still plugged in!

Time to break out the WSM...

its on the right hand side near the radiator

Not on mine, was relocated to fit those annoying braces! Everything's plugged in, fan has continuity. I need one of those infrared thermo guns hehe

At what temp does the fan kick in?

uh...

As inaccurate as they are I might stick one of the FX temp stickers on the radiator, if I can find a visible spot... The one I have on the cylinder doesn't seem to go near 95C unless I'm stuck in stop/start traffic.

EDIT: Not the most ideal place but it was the only one visible, temp sticker now on the top of the right radiator next to the intake snorkel.

I think the fan comes on at 185-195 F

I had 0.5 inch hoses on my breathers as well.
I'm not too sure about oil shuffling, but the torque limiter actually uses centrifugal force to spin oil off so that just gasses come out the breather vent (in theory). But if you lay the bike over and oil does get past the torque limiter, then it creates a siphon effect and continuously pumps oil out.

Are you going to give your loyal followers a heads up just before their out? Ya know.....kinda like insider trading......without the jail time.
Does anyone have torque specs available for the chassis? Im in process of putting some of my bike back together but can not find the specs for torque. I ordered a shop manual on CD from my dealer but havnt received it yet.

LoL, of course.

This is probably what I seen going on when oil was pouring out the breather with 1600cc

Tinken my fan in 100 degree weather on the highway will not come on , if it's on as I enter the highway it will quickly turn off.. Around town stop light to stop light it will stay on but turn of on the long city blocks. I never had issues with coolant seepage untill I leaned my idle out and started tuning out back pressure when I close throttle.. You might be running lean , I know you are if you can hit 115 with 15-43 I can lean my toP end out quite a bit still.
