Review: Good product and a decent price (when i bought mine) - Great product and not hard to install. Put it on my BD125-11. Review: Works and should provide extra cooling - The kit comes with 3 different mount mounting options. I choose to mount it to the intake 90 pipe since I didn't want to bolt it to the head and I my model year didn't have a way to mount it below the tank. My model has an ignition key right below the tank. The cam plate and gasket fit my CRF70 just fine. (actually 88cc with big bore kit) IMPORTANT: When I got the kit I noticed that the radiator had the oil line in/out and mount holes on the same side which meant that I would have to bolt the rad upside down. If I did this I would only be using 1/4 of the rads cooling surface area. This was at first disappointing. I have seen many other people mount these with the oil lines on the bottom. This is wrong! But guess what I noticed that the rad's cage has 4 bolts sandwiching it together and the cage looked reversible so I took it apart, flipped the rad so the mounts were on the bottom and the oil lines were on top. No where did I read that you could do this so I am sharing here and that's the main reason I am leaving a review. After the install I had to top up the oil a little. The oil lines must not be overtightened. Besides its low pressure. Its not like they are hydraulic lines. The oil lines were a little challenging to route and connect because they are ridged and the heads don't swivel so take you time and find the best orientation. After running for a bit I checked the temperatures and the rad was reading 109 degrees at the surface. That is a good sign. It will cool when your ride. Also there were no oil leaks anywhere. Last thing I have the 88cc big bore kit with the high flow oil pump and widened oil port. This oil cooler may work fine without the high flow pump mods but I would consider the high flow oil kit too because of the extra flow that may be required to pump through the oil cooler. Do your research on how to add that kit to your project. ## Features - 【Compatible Models】- The motorcycle oil cooler is universal suitable for Loncin Zongshen Lifan Shineray Yinxiang 50cc 70cc 90cc 110cc 125cc 140cc Horizontal Engines SSR Tao Tao Kayo Apollo Bosuer Xmotos Chinese made pit bike etc. - 【Effective Cooling】- The motorcycle oil cooler can effectively cool the engine oil, the combustion conversion rate of the engine oil. - 【Excellent Thermal Conductivity】- The oil cooler is made of high quality aluminum alloy, which has good thermal conductivity and s the cooling efficiency of oil cooler.
