My first race and first trophy. Yes I’m old, but still have kept this through the years. This and my Loretta’s trophy (actually a plaque) I’m most proud of.

I change oil at around 4 hours. My 450 YZF only holds 650cc, so why would you not unless you are just being lazy. I do the oil filter every other oil change.

It doesn't look like a dowel I've seen in KTM engines. I would have to say a clutch pin may have dropped in during assembly either at the factory or somewhere down the road. Like I said before, something chewed on it and most likely damaged a gear or ... more »

Something broke it up like that. It must have been between some gears or other moving parts at some point. A tear down is a must.

The 2020 YZ450F was mostly new. It had a different frame and many engine changes. The 21 YZ250F got those changes the following year. I would be surprised to see an all new 450 this year, but you never know.

You are correct! I edited my post. I guess I was thinking about KTM coming out with their package that I believe is blue tooth.

The 20 and 21 450 are the same with different colored number plates. The 250 was a major change from 20 to 21.

The 2020 Yamaha YZ450F was mostly all new. Some people say it was 2018 when they changed, but the 20 had a new frame and many engine changes. I would be surprised to see an all new bike in 22, but very few know at this point.

Piston speed limits RPM ceiling. A shorter stroke will allow more RPMS and keep piston speed down. So a shorter stroke and smaller bore would be needed.

Did the ring locator come out and the ring spin in the groove? The ring may be broken there, but the ring gap looks to be in the wrong place.

I remember a chain lube shoot out from years ago where they took two sprockets and a length of chain, washed the factory lube off and then oiled it with different brands of lube. They ran it loaded for a specific amount of time and measured heat and ... more »
