This is true, the Kawasaki Vulcan 1500 line except Drifter used a plastic oil gear. Of course those with problems decided it must be the oil gear itself that is the problem rather then looking at what caused the gear to wear, with the plastics they have today they can be made stronger then the steel counterparts
Take my advice they can jam and shatter at any time regardless of miles, once they shatter your engine is toast within a few seconds, So you are saying the plastic cog saves another part of your engine? The same plastic cog that screws the top end if it fails? Peugeot use those plastic oil pump gears and they fail causing total engine failure, Yamaha use them in some engines but with very few problems even at high mileage ,
I think I'll replace my gear with plastic ones once I get to 100 hours. It's like $30 for the plastic gears and $180 for metal. I'd have to put approx. 18,000 miles on the bike before the metal gears would pay for themselves. I also think you're on the right track with why Beta and every other competition Enduro bike manufacturer uses plastic/composite oil pump gears.
Wow! ...18k miles to break even isn't worth it, in my opinion! ...& thanks for the support on that! I really think that's the truth with consumable parts like that gear! Thanks for watching! Peace!
I have heard that after 100 hours you need to change the plastic gear and everyone changes it with the metal gear. My best guess is that when the engine is new the plastic gear will wear bc the engine is tight but as the engine wears in a metal gear is fine, since the tolerances are not what the used to be when new. Or you could just go back with plastic. Bet there is a forum for this question.
Yeah, I go on the forum to read things from time to time, but there are usually so many different opinions that I'm not sure what to believe! ...but what you said makes a lot of sense to me! Once the engine is broken in, it's a lot looser, so maybe the metal gear is the better way to go! I won't get to that mileage till next year, so I'll deal with it then! :D Peace man!
Dave. .. plastic oil pump gears are commonplace for many motorcycles. The oil pump gears have a certain amount of life like other moving parts. That’s why riders should read their manual and know intervals for maintenance. Steel gears are available if you like. It will last a lot longer than the plastic gears but plastic gears are great too. You just change it out earlier within the prescribed time. Like changing a chain or piston and changing oil or whatever. I changed to steel oil pump gears for my 350 rr Beta. It’s just a lot longer life before changing now. Either way is fine though. To me it sounds like reading the Beta manuals that are free on the support section of the beta website will help you immensely so you understand your bike.Go to the source so you get correct info. It’s Free. Its the factory manuals. Might as well make use of it.

From an engineering standpoint you may be right. On the other hand it may be cost reduction and a little planned obsolescence.

I'm far from even remotely knowledgeable about mechanics, so I am just checking in 😂😀🍻
Ha! Good to hear from you bro! :D

I'll check that out for sure! Thanks for the info, I appreciate it! Have a great day!!! :D
