Messed up on my build need radiator advice
-
@dan28 I'm doing a similar build and 50 rads are very small I think 65 rads are more suited

@ninja thanks, it's my first time welding or building anything like this but I'm happy with how it's coming along
-
@ninja if you see my welds you would think different, maybe when it's running and riding I'll set something up
-
@declan looks good
You have loads of room if mount the radiator in front instead of at the side -
@dan28 I do without the exhaust it's a right hand radiator frame if I use a standard exhaust I'd have to get a different fuel tank and radiator plus seat set up so I'm going to build a simp me underslung exhaust
-
@dan28 I have ordered a new one should be here in a few days, I will measure it when it arrives for you.
They are tiny though.

@dan28 I was looking at one of those on ebay,it would likely me okay if room allows adding a radiator fan would help too

its alot smaller though an the fan for the gas gas rad is expensive even for a used one
i need to find out the sizes of the ktm sx 50 rads both together they should be equalivent to the dtr rad i think -

The manual says that the cooling works by “thermo ~ syphonic action in conjunction with the pump”, but basically when the coolant in the cylinder sleeve is hot enough to actuate the thermostat and open up, the pump will move it. I don’t know any other motor that has the radiator physically above the motor to rely on heat rising through convection
I guess I’m saying that I’d test run it with the rad mounted where you want it and see if it works. As long as the pump moves the coolant I don’t see any problem
I could be totally wrong though!

I could be totally wrong though!If you look at yours the water goes out the bottom rad hose along the metal pipe an to the water pump
The problem I have using the dtr rad the water goes out the bottom hose an then has to travel upwards to the water pump
A smaller radiator mounted higher up would solve the issue an the water would travel down as intended
I m not sure how to add photos on here -

I m not sure how to add photos on hereThe pump would still work and draw coolant up, it doesn’t rely on the coolant ‘falling’ down into the pump. It’s strong enough to lift fluid 2 foot. If it looks good, try it. If not do something that you like the look of!
There is a tutorial on this site for posting pics, if I can suss it you can! I use a phone and imgur (app) to host mine. Do a search, please, it sounds like a wicked build!...

@spookdog I would rather it worked as yamaha intended so would like the radiator higher than the water pump
I trail fitted the gas gas radiator it will fit but as it is approx 15cm shorter then there will be less coolant compared compared to how much is in The standard radiator not sure if that's going to be an issue
