July 21, 20197 yr I bought a 2016 300 4t last year and noticed that American Beta sold an oil pump upgrade kit to decrease engine braking. I believe it was the same as the 2018 models so I bought one. I got used to the engine braking before installing so this past year it just sat in a cabinet. Recently, I have been going back and forth the between the 4T and a 2T and the engine braking was the most challenging part of transition so I finally installed the upgrade. It is just a slightly wider (3/16" maybe) pump module. It makes a significant difference. I actually forgot about the install for about 1/2 of the first ride back on the 4T and did not notice braking so it did the trick.
July 24, 20197 yr Very interesting, never new they had this. Part numbers? Price? how easy was the install?
July 24, 20197 yr Author You need to pull the flywheel so need the appropriate puller. Then it is just a couple of screws to remove the plate...pretty easy. Instructions are in the link. https://shop.betausa.com/p/evo-4t-oil-pump-upgrade-kit-09?pp=12
July 27, 20197 yr Actually got to ride a 2018 Factory 4T yesterday, and yes there was some difference in engine braking, thanks for the info. Not sure if i will mod it yet, got a ****load of other house hold work to do first.
