Well, we attempted our third trip in our New Reeper Sport and had to cut it short again. On trip number 2, it overheated going up a steep incline after about 45 minutes of driving at 55mph. I smelled burnt oil, so pulled over and the temp gauge started flashing. I checked it out and noticed some grease leaked out the front CV boot on the rear axle. I checked the coolant and fan and both seemed OK. I cranked it up, the fan immediately went to high speed and the engine returned to normal temp??? I'm not sure if 55 Is just too much for it or there was possibly an air pocket somewhere in the coolant system from the dealer. Anyways, I test drove it nearby to see if the problem would return, and it ran fine. Well, after attempt number 3, after about a 40 minute ride through trails and a 30 minute return ride home, the smell of burnt oil returned. I checked it out again and the CV boot above the exhaust pipe has melted around the clamp and I lost most of the grease in it. Now I'm waiting for my dealer to let me know what the factory hasv to say. Has Anyone else had a CV boot failure above the exhaust pipe?
If driving at road speeds, 55mph, I would give it a bit of a cool down before jumping into a high load situation like you mentioned. Sounds like you just needed to give the system a bit of a cool down. Usually 5 to 10m minutes in normal low speed mode.
As for the boot. I haven't heard of one failing due specifically do to the exhaust. That may have been the cause, but I haven't heard it related to that. If you have lost the grease and the boot was ran open. I would suggest a close inspection of the CV joint and a thorough cleaning before reassembling to ensure not dirt is present in the joint or boot that could kill it later down the road.
If you believe the exhaust caused the boot failure sounds like maybe some exhaust rap or heat shield may be needed.

I guess the excessive speed and incline was just too much for it. I've done all the radiator mods, I'll add an oil cooler and try again as I bought it expecting to be able to drive it to the beach about 45 minutes away. There's still a bit of grease in the CV joint, but I'll clean it, replace with new CV grease and a new boot. Thanks again
Cyman something is wrong and I don't know exactly what it is. So I will only have to take a poke and a jab as to what is going on. Get your hands on a thermal heat gun and take some temps of things and find whats getting so hot to melt the CV boot. Was it the inner or the outer boot that melted? If its the outer boot I would suspect the brakes are dragging and the little rod in between the brake booster and the master cylinder is adjusted to long. Try getting it on the road and 40+with the gas still applied reach over with your left foot and see if the bake pedal is tight and has no travel. If it is tight then it needs to be shortened about 1/8" and reinstalled. Drive again and do the same test. If its still tight readjust and drive again. If this is not it you will need to find the source of where the heat is being generated from and eliminate it. For some reason mine would only drag the back brakes and this could be the problem. And it didn't do it all the time. But once I got mine out on the road for a long ride I would notice how it felt like something was dragging and like holding the machine back the faster I went. I'm not sure of what your saying about the front CV boot. I'm assuming you are talking about the outer CV boot. Their is front CV boots on the front dif, and rear boots on the rear differential, both have inner and outer CV's. On our 800cc machines the exhaust is routed above the axle and boots but have plenty of clearance that this could have never happen. Your kind of in new territory on these 1100cc stuff and I don't have access to one to give honest judgment as to whats the problem. Can you take some pics of what your looking at?

Lug, you're correct, it's the front CV boot on the rear driveshaft above the exhaust crossover pipe. I've checked the brakes and everything is good, except for the crappy parking brake. I've been running it hard since then and haven't had a problem with it overheating again. I'm going to drill a few holes in the thermostat, drain and refill the coolant system with coolant additive and add an oil cooler as well, just for insurance. I drilled the mufflers today and disconnected my O2 sensor and man it made a difference. I already replaced the horrible little air filter with a completely new, larger intake and conical filter. I believe it's ready for a power commander now. But Soo far, no more trouble. Oreion is supposed to be sending me a new boot so I can replace it.
Your terminology of the front CV boot still has me off, not sure if your talking of the inner or outer boot. But that's ok, sounds like you have it under control. With out pics or the same vehicle as yours its hard to tell whats going on and make corrections. If I went to the trouble of pulling the thermostat I would change the cheap Chinese one out with a good Stant or Gates one. Drop the temp down some from 195 to at least 180 or 160 degree. They put a high temp one in to help burn off emissions and run cleaner. We don't care about that as we don't have emission inspections on these anyway. So get it down and it'll help out the life of the engine anyway. I would also highly recommend a coolant evacuation kit to refill the system. It will save you some headache of wondering if you have all the air out of the system or not. Sounds like your on the right track and have fun on the beach. We'll be doing the Texas beach on May 20th at Port Bolivar, looking forward to that one for sure. Thousands of Jeeps and off road vehicles will be there.
Just purchased a new 4 door reeper 4 and sold my reeper 2 door. after driving it about 60 miles after I bought it ( had180 miles before I got the machine) so less than 300 miles I smelled oil or grease burning so I immediately pulled over to check the problem. I found that the cv boot on the rear drive was slinging grease out. I suppose this was cause from the heat off the exaust just above the drive shaft. due to oreion redoing their website I haven't been able to get a replacement under warranty. never had any problem with the 2 seater just wander why the issue with the4 seater. drive shaft is located in the same spot under the exaust pipe. hard to swallow spending 18000.00 on a machine and can't get it fixed in a timely fashion.
