The engine gained the nickname “Shovelhead” due to the look of the rocker covers having the appearance of an old coal shovel that was flipped upside down, giving the appearance of a shovel. While the engine did have problems earlier in its timeline, the new and improved motor gave Harley-Davidson a 26% sales increase.
Panhead engines were produced from 1948 to the mid `60s when it was replaced by the Shovelhead. Its inception was just in time for the postwar motorcycle boom. The valve covers on these bikes look like small cake pans. The purpose of the Panhead design was to help with oil containment, however, it wasn`t successful.
Name for its unique head design that looks like an old coal shovel flipped upside down, the shovelhead represented a troubling time for Harley-Davidson. Despite the challenges, Harley-Davidson sold motorcycles with the shovelhead engine from 1966 to 1984 and enjoyed an ever-increasing market share.
A Shovelhead Harley engine was produced from the mid-`60s to the early `80s. The top of the rockerboxes resemble the curve of a shovel, hence the name. A Pan head was produced from the late `40s to mid-`60s. The valve covers on these bikes was a stamped metal pan, hence the name.
The Problems Start

The design of the Shovelhead was flawed from the start. The barrels had only ten cooling fins which weren`t sufficient and the engine ran hot. Smoky engines were common as oil would pool in the cylinder heads and leak down the valve guides to be burnt in the combustion chamber.

Early versions, such as the 1966 FLH, produced 60 horsepower, while later versions, like the 1984 FXWG, generated up to 65 horsepower.

The Shovelhead was the third rendition of Harley`s OHV V-twin, following the Knucklehead and the Panhead.
Use a good quality unleaded gasoline. Use at least 91 (95 RON) pump octane (R + M)/2. Octane rating is usually found on the pump. Remove fuel filler cap slowly and fill fuel tank slowly to prevent spillage.
1984 was the last year of production for the Shovelhead engine.
While pan head screws do not sit completely flush with the joint, they are great at achieving minimal protrusion above the surface. Thanks to their rounded design, they do not present any shape corners or edges. They are ideal to be specified in tight-fitting spaces or where a nearly flat surface finish is desired.
When first released in 1948, the Panhead was available in two engine sizes: 61ci and 74ci. This gave the Panhead Harleys an early horsepower range of between 50 and 55 horsepower and a top speed of around 100 mph. The cast-iron cylinder heads of the old Knucklehead models were replaced by aluminum alloy cylinder heads.
It is just as reliable as the mechanic that owns it. And yeah, if you want to own one, you will want to learn to do at least the majority of the wrenching. If built right, yes. There are good and bad builds out there.
S&S Shovelhead style rocker arms have a nominal rocker ratio of 1.5:1, and high precision CNC machining insures that this ratio will be consistent in all parts.
The 1966-68 models still had generators rather than alternators. Linkert DC carb (M has round floatbowl, DC has square-ish bowl), 8.0:1 compression.
The Harley-Davidson Evo was not only more powerful, but it ran cooler and smoother than the Shovelhead. The 80 cubic inch Evolution motor was produced between 1984 and 1999.
Harley-Davidson has announced a new Screamin` Eagle 135ci (2,122cc) Stage IV Performance Crate Engine option for 2021 and later touring models. This engine upgrade will be the biggest and most powerful street-legal crate engine H-D has ever offered.
For a small to medium-sized motorcyclist a 125 cc, 250CC, or 300 cc is an excellent choice. For larger riders, a 400 cc, 500 cc, or even a 600 cc would be ideal if no more than a twin cylinder. A 600CC four-cylinder sport bike would not be a viable choice for a beginning rider.
Aluminum heads will dissipate heat faster. This allows for higher Compression Ratios with less risk of Detonation. The cooler head also delivers a cooler air/fuel mixture to the combustion chamber. Cooler air is denser and can make more power.

The Twin Cam 96 was released for the 2007 model year.
you get more power with a v-twin engine than you would with a traditional single cylinder engine. They are quieter with lower vibrations, which means less wear on the other components leading to a longer life and reduced maintenance. The V-twin engine also runs cooler and burns fuel cleaner.
Using higher octane fuel will reduce premature combustion. It still varies from engine to engine, however. Many Harley owners have ran 87 octane in their Twin Cam bikes without pinging, and have gotten a lot of years out of their motorcycles. But some have had to stick with higher octane to keep it humming smoothly.
If you own a 4 stroke, for example, the 82-octane works just fine, but for a 2-stroke, you should go for the ethanol-free higher octanes (92 and 93) because the lower octanes tend to detonate. Two-stroke dirt bikes also require a special fuel/oil mix.

I have a 2004 60 hp yamaha 2 stroke outboard engine that doesn’t start or run well. Once warm and in the water it will idle in nuetral and also in gear. It accelerates in neutral but will die or lack power if I increase throttle while in gear. Engine will somtimes get to top speed but often while running at top speed engine will start to slow rapidly. Engine has full range of operationout when out of the water where there is no load on engine but is still difficult to cold start. Before these recent problems the engine sat up for several months and I had to change the impeller and spark plugs. Spark plugs fire, cylinders have proper pressure of 100, 100, and 110. I cleaned some fuel lines and filters and got new gas.
ANSWER : Every sympton you are describing here can be attributed to fuel starvation due to blocked jets and or water in carbs, when your engine dies does it die with dry plugs, or wet oily ones?

LX 188. Engine suddenly dies. The fluel in the bowel of the fuel filter is empty. If I crank the engine the filter becomes dry and is collapsing some but the engine does not start. When I remove the supply line from the fuel pump to the carberator and crank the enginge there is a strong stream of gas being pumped out. I tap on the carberator ??? is the float is hung not allowing fuel to enter. Cranking the engine with the line off refills the bowel of the gas filter. Reattache line to the carberator===engine starts. Ran perfect for 20minutes then suddenly died. Repeated all the above and engine again started. What to do to fix this? Thanks
ANSWER : Debrie inside the needle and seat area which has to be cleaned out with carburetor cleaner and compressed air

ANSWER : I would recheck wiring at stator.

Cannot turn engine over to start. Ariens 924 snow blower
ANSWER : Pull spark plugs and see if it will pull over if not fuel may have filled the crank case drain & refill to proper level (starter is stuck in lube shaft & movethe gear up & down by hand to free up)

My engine revs on high by itself and runs rough
ANSWER : We had the same problem with our snowblower. we tried everything. ponits, adjustments. even converted points to electronics. we ened up putting on a brand new carborater and it runs great now. save youself the headaches and buy a new carborator. we spent $87. so much better

2 problems with Tohatsu 9.8 4 stroke O/B engine. 1. The spring that controls the choke does not appear to be screwed in or connected. Should it be? Screw size? 2. When I squeeze to inject fuel, I notice that fuel is squirting from the side of the carburetor. I also found a very small yellow gasket at the bottom of the engine case – looks like something that fell out.
ANSWER : Hi vvs9,I see that you are having issues with your Tohatsu 9.8 4 Stroke O/B Engine.check this link, this is where you can get parts and the manual for machine, you mentioned that Fuel is squirting from the side of the carburetor and that there is a small gasket at the bottom of the engine case.Also that you mentioned there is a spring that seems to be unscrewed, I believe that is part of the Stop Switch. See Link below for more details.See this Link this is where you can check the manual exactly for the Model that you have.I hope that this helps.Thank you for choosing Fixya,mvincentc
