Hi there, So I am starting racing with a new bike, 1985 (rfvc) Xr250r. This bike is a race bike, however I was wondering how to keep it cool as it is air cooled, now the oil I use doesn't tend to overheat too fast however after a full day of racing i'm sure it will. How can I install an oil cooler? I have read article about people modding the xr200r (Rfvc) to have one. But not how to do it... So How do I do it?

Hi All, Just starting the big task of a full rebuild on my XR600R. There will be many custom modifications that my be of interest. There are so many new parts going in that it's easier to say what hasn't been done. Pretty much just the engine cases and gearbox will be be left alone. I'm pretty annoyed that the LH crank bearing didn't come, so I had to re order it. Below (right) is a 100mm 9:1 Wiseco piston, quite a bit shorter than the original. Should make for fast revving I suppose.

Picked up a 1984 XL350R in nice condition and I'm currently rebuilding the engine. Of course it had the classic overheating problems and lack of oil to the left side of the valve train. I keep reading about "make sure you add an oil cooler to your XR/XL350" posts, but nobody ever tells you how they did it or posts any pictures! I'm guessing the oil filter cap/cover needs modified by drilling and tapping then blocking off the original connection port between the pump side and filter side. Can anybody shed some light or info??

I’m building a bike that I wish Honda would have done. The bike is a CRF450 chassis with a 400ex engine. Basically an XR400 with electric start. My question is, “How much oil does this motor pump out, up to the frame, in a given minute?” Short of just pulling the line off and starting the bike and watching to see how fast it can fill a quart bottle. Does anyone know? Reason for asking this question is because I’m building oil tanks in place of the wet frame that was found on the XR400 bikes. With the two tanks that I’m placing on the CRF450 frame in place of the radiators; I need to do a cross over from one tank to the other. I would like to run the bike with both tanks more or less full, in order to take advantage of the most cooling I can get. I just don’t want to starve the engine for oil waiting for one tank to fill up to a high cross over. On the other hand I don’t want a low cross over and lose out on the cooling ability of the tanks if they’re going to be mostly empty while the bike is running. Does anyone have a realistic idea on how to get a cross flow effect without taking forever to get oil to the return line? A few videos can be found of it on YouTube under “XR400AF” if you care to watch them and give me any ideas for oil line/tank. Thanks in advance for any help.
