Pretty obvious where Earl's lines hook up into filter cover. The one Mark shows, looks to route different from Earl's and seems hidden by the bash plate and I can't figure out how/where the lines go. At $338 USDollars for the Earl's, I think I'll just change the oil after every other ride or so. Looks like it would only be good for paved roads. I would rip the lines off in no time the way I ride wink

 They go to the oil cooler hook up points that TTR250 come with as standard

some of the early TTRs came with oil coolers as standard..

Look on yours you will see 2 plugs in the side cover... bottom is oil out

the top is oil back in... but you have to put a blocking plug in the inside

of the cover oil way between the 2 attachment plugs to route the oil though

the cooler .................

Been thinking of fitting an oil cooler for a while and i'm going to fit one over winter.
i think i will fit one of these APS coolers www.demon-tweeks.co.uk/motorsport/oil-coolers-accessories/automotive-plumbing-solutions-oil-coolers (115mm x 53mm, 7 row )
I will need to make a custom bracket and guard. All the plumbing fittings are easily available but i might get some hoses made up by Pertek
www.pirtek.co.uk/products .

I take it that oil cooler pipes with a 6mm bore will be ok ?

I think 8mm bore would be preferable to minimise drag. I've just gone the Robin Webb route, which was not cheap, but the Off Road cooler is a work of art and a thing of beauty to behold! (Their outlets are 10mm id, but built for various 600cc + bikes) I also found these guys, who have a variety of coolers at more reasonable prices:

www.ooracing.com/store/pit-bike/cooling.html

Hmm, don't know if that link will work, but type in the address and you'll get there! Some of their coolers, whilst made for pitbikes, look similar in scale to the standerd ttr one. I only went for the Off The Road one 'cause it looks bulletproof for the vulnerable spot it's located, and I'd just got paid!

I also have some allen head bolts of the correct thread for the oilway blocker bolt (the internal one) - you just need to cut to length, if you want one... (Once you've got the clutch cover off, and taken the existing "short" bolt out, you can see the 2 oilway holes and how far down it needs to go to blank the one off, although I think Brian's posted the length further back up this thread somewhere)

I also toyed with the idea of fitting a high pressure fuel filter housing (with the filter taken out) as an extra oil reservoir for more capacity, but it looked too ungainly so I didn't bother.

http://www.ebay.co.uk/itm/like/271074199470

Wasn't intending to pay that much for one though!

Martyn: I think that pic you found is on a Serow engine - doesn't have the cooler outlets that the ttr has - hence the filter cover mod, which is very common in pitbike circles, but more expensive than the 2 banjos, 2 banjo bolts and on m12 fine thread bolt you need to convert the ttr.

Bit of progress with parts. Got a pair of 90 degree banjos like Robin used and a Honda 125 Varadero oil cooler on the way. Pics to follow when it arrives.

Sorry for the late update, here's the Varadero oil cooler cleaned and sprayed with heat resistant paint. 

Working out how to fit!

Very nicely made brackets Locky, do you have some fabricating tools at home then?

Excellent job Locky! And it works with a shorty pipe - unlike the standard TTR cooler biggrin

Yes i was concerned the cooler pipes would be to close to the shorty pipe, but think it's fine.

Thanks hanzo, i think it would be possible to adapt any small oil cooler to fit the TTR. Size is the important factor as you don't want to damage it if you have an off. I added roughly 250ml extra oil but i'll do an accurate measurement next time i do a oil change.

I am replacing my 93 model with an 04 blue TTR.  The old bike has an oil cooler fitted, so I will swap it over.  Isn't there a bolt on the inside that I also need to mover to the newer bike? If so, has anyone got a pic of the bolt I need to get out?

Thanks

Lee

Hi Lee

Lots of information on this thread Lee!

The specification of the bolt is in my post of 8 October 2012 wink

Thanks Brian

Do you know the length of the bolts that will replace the 26mm banjo bolts, or does it matter as long as the crankcase is sealed?

The fiche shows that you can use the same size plain bolt and washers as used inside - see diagram - part # 19 and 20. You just need to make sure the holes are blanked off as far as I can see.

I can tell you that one is absolute crap Pete. Its made from some type of fake metal and the fake braided cables are plastic, bolts and washers are kinda ok tho.

Look for the ones that look more like a good quality alloy radiator but dont use the lines that come with them, get your local hydraulic guy to make some up for you.

Haven't fitted one to a ttr but we put one on my little brothers 450exc and its seems to be working well so far. (ie engine hasn't melted yet :)

i still have a aftermarket oil for sale pics on forum

A question for the brains trust - which way up do you mount your aftermarket cooler? For example if I have a cooler with an inlet and outlet right next to each other, I'd mount the cooler with them facing up towards the tank. My theory is that this way the oil won't drain back into the sump when you switch the bike off. What do others think?

All the aftermarket coolers for XR650s are like this (not the xr400 ones behind the head stem) - there is a bloke doing kits on advrider for them. See these pickies below

IMG_0035.JPG

 

IMG_0034.JPG

Will the little Ttr have enough oil pressure to mount a cooler with the inlet and outlet up Like this? Or will it struggle?

Also where are people getting their fancy 90 degree banjos? I can't seem to track them down.

The only issue with those banjos shown above (by Moo) is that the bolts are m12 1.5 bolts. I thought the thread for the banjos was actually m12 1.25? In the picture of three bolts earlier in this thread it said they were all 1.25s. So you could use the fitting but not the bolt. Anyone know for sure?

please somebody summarize, WHEN EXACTLY is the need of cooling oil in TTR 250?

I have a 2004 (parked long time by an old dude) now I plan to use it , mudding, abandoned coal mine, forest. Location Hungary, middle Europe, weather winter zero summer 35 degree celsius.

THX

what are GOOD working temperatures of factory stock standard TTR 250 (I measure it with infrared laser pointer temperature thingy) and what are overtemperatures, to avoid?


thx

I used a water cooled kawasaki KMX 125 2T before (for pretty harsh bashing) so I am used to check water temp time to time.

I can't find any real data on oil temperatures and the difference an oil cooler might make - sorry!

I fit an oil cooler to my 325 to (a) increase the volume of oil and (b) to (hopefully) keep the engine temperature down when stuck in a muddy or rocky lane with the engine working hard and the TTR going nowhere biggrin

It is more of an insurance thing for me.

I found the following comment from another member and here it is just for information:

"When I blew up the big end it was after pushing the bike all day on the motorway at 65 to 70mph with ambient temperatures in the south of France being 40ish. I hadn’t been watching the temperature (I run temp’ stickers on the back of the clutch now to get an idea of what’s going on) and after stopping at a toll booth I guess there was no where for the heat to go, being stationary, and within the next mile it went bang. The same bike previously went 5000 miles across the USA but I never went over half throttle (I mark the twist grip), and kept going around 60mph. and the TTR was happy even in deserts etc."

just a thought...

 I wonder if the restiction to air flow though the fins counters any gain from the oil cooler...?

Hi all just wandering if any happens to know anywhere I could get banjo bolts for fitting an oil cooler. I know there m12x1.25 but really struggling to find some of the correct length.

Any help is greatly appreciated.

Not sure that you have to be 100% on the length just the M12 and 1.25mm thread pitch. If you buy longer just check they don't bottom out when fitted and, if they do, just cut them to the correct length wink

A brake banjo would be fine - lots available - see here
