My catch tank

[That Guy]

Right, I thought they looked a bit like bolts there, dunno about that. The core is a wee bit flimsy for bolts maybe? the idea (of bolts) going through there somehow doesn't sit right with me. Maybe cable ties in some sort of clever arrangement would be the go with some thermal insulation tape between the bottle and the radiator core. If she boils in the snot the boiling coolant wont be stored hard up against the radiator possibly causing thermal buildup pushing heat back into the core?? dunno just a thought.

I've got one on my RMZ450 from MR motorcycles - works a treat no problems at all.

Probably the last time you rode, when was that? huh?

And you call yourself a dirtbiker, pfft!

haha go ride some logs and stop looking at your own roost

[Pornstar]

Speaking of own roost, I always feel like mines not big enough, kinda like guys who wory about their other sizes , but with me its just the roost, its probably fine,but....

this may be of interest

Great idea! But you can take it a bit further i think.

There is no reason why the frame cant be used as a catch can on the CRFs a small 3mm hole at the bottom of the main spar left or right side will work mint with no strenght loss. Ive herd of people filling the frame with fuel on the CRFs for eduro rides.

Any thoughts on this?

I used a garden hose water filter that you can buy at bunnings i think it was $8.00 has a entry and exit spout at each and and is small enough to fit between the frame and radiator of my yz i will try and get pics i have had it on my bike for 12 months and its been great works really well... and you have to look really hard just to see it ..kinda looks like the one in the pic

Mean Maori mean...

Makes the boil overs easier to deal with aye.

go another step further again and fit some round fittings onto the frame, cycle the cooling system in through one side and out the other, adding another few litres to the whole system.... good luck making that overheat!

Now we are 'cookin'

[CRF119]

Remember we dont want to make it run to cold these bikes dont have a thermosat. Running to cold will do as much damage as to hot. Also the hotter you can safly run a combustion engine the more performance can be had.

Just dont want to boil

Good idea for the wires i think maybe not for a mx track.

Ive herd of mx teams blocking sections of radiators to bring engine temps up in cold parts of the world.

James Stewart was doing this in the supercross series this year,

however in the outdoors most of the factory teams run oil coolers on their four strokes to combat extreme heat

[CRF119]

Can you get oil coolers for the CRFs? The YZF would be easy it has external oil lines

[scott411]

yes they plumb them in, have a look at close up pics of the factory connection crf250's and you can see them, i have not seen how they plumb them up to the crf's, have seen them on kxf's tho
