How much heat from the engine is taken away by the oil cooler? How much cooler will the engine be with a larger oil cooler, like the race one? I live in Atlanta and the engine gets really hot if I get stuck in traffic, or have to do a lot of the ol' stop and go. Right side air scoop is being considered, but that will only help when the bike is moving. Any thoughts, opinions, or actual knowledge on the matter? Thanks in advance. | ||

I've been curious about this too, Glitch, and have actually considered remounting the existing cooler in a different position for better airflow through it. I just don't know how much more effective it would be. | ||

"Right side air scoop is being considered, but that will only help when the bike is moving." I think the same holds true with the oil cooler. Having said that, I think it might be a good idea. | ||

What about mounting a small fan on the oil cooler? Seems like when you need it most, it's getting no air flow. | ||

I think the same holds true with the oil cooler. Half right, with a larger oil cooler, you also get more oil capacity, in turn gives you cooler oil over all. By how much is the question. What about mounting a small fan on the oil cooler? That's a thought, but that would be a last resort as I want to keep it as simple as I can. | ||

My operating temps are around 400 F at the rear head. Cylinder surface temps are about 250-275 F which is cooler than a twin cam 88. With the stock scoops the bike does a good job handling the heat if it is timed correctly. | ||

Agreed, until I hit traffic. If I'm out riding in the mountains, it's not so much a problem, get to the city...problem. My bike is in excellent tune, but that helps little while in the ol' stop and go here in Atlanta. | ||

"Right side air scoop is being considered, but that will only help when the bike is moving." My plugs show[ed] that the rear runs cooler than the front cylinder already... | ||

Man, a small PC fan rigged up on the oil cooler with a little hidden push button would probably do wonders, I wouldn't think it'd be too hard to do either... Hmmmmm good thought... Slap on the larger cooler at the same time and I'd call it a day with any thoughts to that issue! (Message edited by ride365 on July 05, 2006) | ||

Agreed, every Harley engine that I have messed with has a hotter front cylinder. I found that retarding my timing made my bike run much cooler. I am going to check TDC to see if there is a disparity with the mark. There are too many people with no problems at all to explain why I had to retard the timing so far. By the way I am getting 55 mph. My timing can't be off by much! | ||

My timing was a bit off from the factory. It was set too far advanced. That was taken care of many thousands of miles ago. Nothing wrong with my bike, only the heat. Is there a computer fan that could hold up to what would be in store for it being mounted to an XB? Rain, vibrations... | ||

Hey Glitch have you considered one of those billet oil filter cooler things? something like this: http://cgi.ebay.ca/1-BUELL-FIREBOLT-883-1200-SPORTSTER-BILLET-OIL-COOLER_W0QQite mZ230003174151QQihZ013QQcategoryZ34284QQrdZ1QQcmdZViewItem I don't really know first hand if it really works or not... the theory is sound though more surface area for air cooling.. just my 2 cents.. | ||

Noangel, hadn't thought of a heat sink for the oil filter. Thanks for the food for thought. | ||

Is there a computer fan that could hold up to what would be in store for it being mounted to an XB? Rain, vibrations... Glitch, good question. You could try robbing one or two off of junk computers and seeing how they work out. I'd think they'd be pretty easy to come by. (Somebody gave me one to use for supplemental cooling on my S3 although I haven't tried it yet). If it looks like the junker computer fan holds up reasonably well, invest in a better new one. | ||

Due to the nature of my career, I got plenty of fans to try out. The first one will be one from a power supply, as it looks like it could take the most abuse, and is the largest I have on hand. I just have to figure out how to run the wires, doesn't look to be a difficult task. | ||

That one ought to be able to hold up to some good temps... Let us know once you've had it on for a couple weeks, I'd be curious to see how well it does, I wouldn't think it'd break down very easy... Maybe put a small fan sized spacer around the circumference of the fan to keep it from touching the oil cooler, like a gasket of sort, except thicker... Just an idea |
