correction - there are two hoses - so much for looking at my own photos before posting... it does look a little like the oil cooler posted by papasmurf, though the hoses are run differently. Looks like I will need to replace the Y-tube on the bike when the radiator comes off. and as with everything else done on this bike, there's more research to be done!!!

OK, from your picture here your bike is definitely the USA market AVL Classic (with the military paint job option), NOT a Sixty-5, the rectangular oil pump cover and shorter barrel are the clues.

The Sixty-5 uses the old style iron barrel engine, the AVL engine was changed in a number of ways, including the high capacity oil pumps which are gear pumps rather than the oscillating (good word for Sunday night, yes?) plunger pumps on the older model. The better oil circulation on these models will probably help in hotter conditions, as will an appropriate choice of engine oil, and no, we're not starting on THAT subject now!



The AVL Classic was sadly not something the UK importers wanted to bring in, we only had the Electra-X with its rather quirky styling.

I suspected it was the AVL. now i need to figure out which online part manual to use from elsewhere on hitchcock's website. there doesn't seem too be an AVL that has a front drum brake in their list.

Oscillating - excellent word! :-) LOL

short term work to accomplish is to simply replace the two hoses that connect the bike to the radiator with one hose that connects the bike to the bike! i'll worry about replacing the actual tubing when i've got more braincells to work with. removing the radiator/oil cooler will be victory enough!

Hi, it looks like oil is taken from the rocker feed through the cooler and back to the sump, which makes no sense. How does it get back to the oil tank as there appear to be no feed to rockers, unless its out of shot. Vince

Leon's picture is for a classic Bullet, not applicable to the AVL engines. What the picture shows is an aftermarket accessory for the traditional Bullet engine which takes the oil feed to the rockers directly from the big-end's oil feed rather than the scavenge/return oil supply, via some jazzy stainless braided hose. This was, I believe, first used by Swiss motorcycle genius Fritz Egli when developing his Indian Bullet Tuning packages back in the 1990's and something similar is still available if from Jochen Sommer in Germany if anyone really wants one. Personally I think it's a solution in search of a problem.

This kit is no use for the AVL/Electra-X engine however, as there's nowhere on the AVL timing cover to take the supply from, unlike the older Bullet which has the handy screw-in oil feed plug. You could have one modified, but why bother? The aforementioned gear pumps put plenty of oil up to the rockers.



Getting back to StogieRob's picture, we can't actually see what the upper hose off the oil cooler connects to, but I suspect the only way it would work would be by reconnecting with the upper part of the original rocker feed pipe. Logic would dictate this, which I assume the previous owner of this bike understood. Once this thing has been removed you can re-fit the horn in its original position, onto the thearded boss welded onto the left hand side of the frame's front downtube (on the second picture, which I didn't post. Where's papasmurf when you need him? ;o) )



Having an AVL Classic shouldn't be a problem with parts lists/manuals if you remember this: the engine, primary drive side and the electrics are the same as the Electra-X, the rest of the bike is mechanically identical to the Sixty-5 (or the 5 speed Bullet Deluxe, another model we were never offered). The Military designation is down to nothing more than the army green paint-job.

As Adrian explained. Also, there is feed to the rockers. One advantage of the set-up is there is the sight gauge where oil flow can be checked, whilst the bike is stationary of course.
