Twin radiator
-
@Calum what radiator is that mate
-
Why bother, DTR already runs too cool with standard radiator, with twin it will likely run like crap and weigh considerably more?
@Glynn123 and because mine runs hot I do alot of like tight green laning 1st and 2nd not much air flow

@Glynn123 My DT would see temperatures up to over 100 in the summer.
At the end of the day, once you start tuning the engine you need to keep the temperatures down.
@Calum mine is also getting hot it's Athena 170 tm35 blaster 200 vforce reeds and few more bits need to keep them temps down wich I'm struggling to do I've got waterless coolent ready to go but I want to add another radiator and see how that helps I run a cooling fan to and still gets to like 98

@ryanjimccfc Waterless coolant will result in it runner hotter.

@Calum okay then I won't bother with that what second radiator can I use
@ryanjimccfc You can use whatever radiator you want. Just make up some brackets for it to fit.

@Calum I do have a set of wr200 radiators from a previous project but there are smaller in size than the dtr is it worth doing both or just simply adding the 1 extra they are shiny alloy so they look a lot nicer
-
It's a shame I don't have a dt200 one cause that would bolt straight on

In the heights of summer hammering my DT flat out for hours on end through mountain passes etc I seen a maximum of 80 degrees c after sorting my cooling system and head gasket out. Heard the same from others over in Norway and Germany, even with higher tuned DTRs during long burnouts etc. I know when I used to do alot of trail riding in humid woods my DT would sit at around 80 degrees in summer, where my trials bike would occasionally boil. Theres nothing wrong with the standard cooling system, im pretty sure BARacing are still running single rads on their bikes also.

How do I go about plumbing it all up just y piece it all In?
-
@Glynn123 that may be the case but mine is not good enough for what I'm doing with it hence the post
@ryanjimccfc just saying you should possibly look elsewhere, sounds as if there's a problem in the cooling system to me
-
I'm guessing these overheating bikes a a tip top cooling system, with a rad in A1 condition, pump working as it should be, cooling galleries in the head and barrel free from corrosion and debris, etc, etc? As these bike are sold worldwide with the same cooling system and some areas of Europe have higher temps and higher altitudes than we see.
-
I've got A new radiator new pump it's a brand new top end all new cooling hoses good quality Coolent no air locks digital temp gauge so I can see what's going on and the bike is getting to hot it's getting to like 110 115 and personally I think that's way to hot I even have a cooling fan not a pc one a proper radiator fan to help with air flow when I'm off roading and I just carnt seem to get control of the temps which is why I'm wanting to try a twin radiator set up
-
Engines running lean run hot, whilst 2 strokes perform better on the edge of seizing is this what you're looking for, or would it be worth trying to richen up the motor a little and see if the temp drops as something doesn't seem right. I've tuned quite a few bike and car engines over the years and only minis and imps had issues that required doubling the size of the rad.
-
Okay I'll look into the jetting but bike runs really well with jet it has I'm not saying it the right jet but I thought it would have a white plug if lean

Hi Ryan,
Just checked through some old photos of my RD350LC I had in the 80s with a Stan Stephen's stage 4 barrel porting on it, head lapped to the barrel, microns, KnN pod filters and running on 4 star and it was on a std rad.
Thrashed everywhere the temp was in normal limits. -
Hi Ryan,
Something that just entered the old grey matter, is the rad cap the correct one, in good condition and is it rated for UK ambient conditions?If you're not able to get the system at the right pressure the water will overheat and you will have cooling issues. It could be worth splashing out on a new genuine rad cap.
Cheers
