Don “Woody” Wood, Livermore Falls, Maine, knows Harley-Davidson motorcycles. He’s been riding and racing “Hogs” for 42 years; building, repairing and modifying them for more than 30.

He owns Doc Wood’s V-Twin Motorcycle Works, LLC, and is an expert when it comes to Harleys.

He owns five Harleys, including a Harley drag racing bike. They’re all run exclusively on AMSOIL motor oils and lubes.

“That quarter-mile, it’s wide open,” Wood said. “It’s like putting 30 to 40 days of street riding on the engine. It’s hard on the bike.”

He tears down the engine every winter and finds it’s clean with very little wear on the engine parts using AMSOIL motor oil and lubes.

“AMSOIL is just the best oil you can run in your bike,” he said.

He recommends breaking in a new engine with conventional motorcycle oil for 2,000 miles before switching to AMSOIL 20W-50 Motorcycle Oil in the Big Twin. Wood further says that in his opinion the AMSOIL 10W-40 Motorcycle Oil would work as well. After a 500-mile break-in with conventional motorcycle transmission oil, he advises switching to AMSOIL Series 2000 75W-90 Gear Lube in Big Twin transmissions and AMSOIL 10W-40 Motorcycle Oil in Big Twins Primary Chain Case.

In Sportster models he uses the AMSOIL 20W-50 Motorcycle Oil in the engines, but in his opinion, Wood said the AMSOIL 10W-40 Motorcycle Oil would work as well. Wood further said that on the Harley Davidson Sportster model he uses AMSOIL 20W-50 Motorcycle Oil in the Primary Chain Case as the oil shares a common compartment with the transmission. Wood said he prefers the added viscosity but in some cases it will create a dragging clutch.

Wood also installs AMSOIL Medium Shock Therapy Suspension Fluid in the front forks.

After switching to AMSOIL he often needs to set back the idle by as much as 400 rpm. “To me, that is cheap horsepower,” Wood said. “We’ve found AMSOIL products give us reduced oil temperature, easier starting in cold weather, better fuel mileage and reduced wear on parts.”

He told the story of a customer who had his transmission rebuilt by Wood, who put in AMSOIL Series 2000 75W-90 Gear Lube, and was told to come in and have it changed again after 1,000 miles. “He decided to change the oil himself and got distracted and forgot to put the drain plug back in,” Wood said. “He didn’t notice the oil running through, and drove the motorcycle for 25 miles with no oil in the transmission to our shop. We noticed a few drops of oil under the bike and checked out the problem.” A new drain plug was installed. When the tranny was flushed, no metal filings were found, Wood said. It was refilled with AMSOIL and test driven. “I could feel everything loosening up right away,” Wood said. “That was six years ago, and the transmission is still going strong. This is why we run AMSOIL in our shop.”
 

Do his Harley riders question his use of AMSOIL?

“In my opinion GOD had AMSOIL created for Harley Davidson motorcycles,” Wood said. “They know I wouldn’t sell them something I wouldn’t use myself. Once I get them switched over to the AMSOIL, they just don’t look back.”
