This was originally posted in the black hole of the Knowledge Vault, and reposted here for obvious reasons... Having been a squirter of sorts for most of my life, I think I can speak with some "authoritay" on this subject so near and dear to me...and my wallet. Heck, Dad used to call me his little "Squirt" back before I understood why that always made Mom blush and him snicker. I have most of Mom's inheritance tied up in two 88" engines (thanks Mom). These engines produce among other desirable things, copious amounts of heat. The question was, how do I prevent this excessive heat from destroying the fruits of my inheritance. I have aluminum oil reservoirs and external oil coolers, Pro Flow oil pumps and try not to get stuck in traffic, but is that enough? I do know that the MoCo realized that they had reliability problems caused by overheating on these engines, especially on the rear cylinder. If you look at our bikes, there is a dead air pocket behind the rear cylinder near the starter, where temps grow astronomically. The fairings and covers on Buells restrict air flows in this area, exacerbating the problem. The MoCo's solution to this problem is that the new Buell engines have a fan, oil cooler and "squirters" that send jets of oil onto the underside of the piston and cylinder wall. By installing oil squirters, HD sought to reduce cylinder and piston temps, thus helping to prevent oil breakdown and engine damage. This made sense to me as these are air AND oil cooled engines. As a side benefit, the cooler internals should increase horsepower by reducing friction and therefore, increase reliability. But what about the rest of us who still have dinosaurs without these technological gizmos? The good news is, I have found that older engine models can be retrofitted with squirters, so that you can get the advantages of the new technology in your older model Buell. These squirters are available as a kit by a company called Hot-Shot Motorworks in Upper Sandusky, Ohio (419-294-1997), for $39.95 for the kit. (They are also sold by Axtell, and are available in all its big inch kits.) They are machined from solid billet and require some machining on a small area on the inside of the pinion case for mounting. Hot-Shot also installs these kits, in addition to having a complete machine shop for any engine work. Dan Fowler has been in this business for a long time and made his name, in part, by building XR750 engines for such notables as Steve Morehead, and others. I would say that I trust Dan, as I let Hot-Shot built both my 88" engines. The down side to this modification is that the engine cases must be split to install them. But if you are building a big inch or high performance engine, the additional expense for installing squirters is negligable, considering the increased reliablity. Dan told me he spent many hours of testing on the dyno during development and observed a reduction of 200 degrees in cylinder temperature by using the squirters alone. He "abused" an XL EVO engine by running it WFO continuously for many hours on a dyno with a water brake load. He monitored the cylinder temps, head temps, exhaust gas temps, oil temps, oil pressure and more. He then disassembled the engine and found no damage at all. Kids, don't try this at home! I was so impressed by these findings that Hot Shot has both of my 88" engines now, installing these squirters into them. I believe they will be worth the money by increasing the reliablity of these big "heat generators" of mine. We will see. I am wondering if any of you guys in the performance engine building end of the business have used squirters? For the record, I am not affiliated with Hot Shot in any way, except that I have given them large sums of my inheritance. I will keep you posted on how these work out for me. | ||

HUHUHHUHUHUHUHUHUHUHUUHUHUHUHUHHHUH HUHHUHUHUHUHUUHUHHUHUHUHUHUHUHUHUH You said Squirters again. | ||

Some time back people here were discussing the fan kits for the Japanese destined Buells to cool the intake apparently due to the fuel/gas used over there in Japan. (At first I thought this was going to be about squids.) | ||

What about the fans? | ||

OK way off topic here but I just gotta, (Spidey your gonna get a kick out of this one) Would you say SQUIRTERS are the complete OPPOSITE of HOOTERS | ||

HUHUHUHUHUHUHUHUUHU HE SAID SQUIRTERS HOOTERS HUHU HUUU HU. | ||

Fans, less expensive method of a little extra cooling than adding underside squirters. A site search on +Japan +fan should get hits. | ||
