"Air Hammer" YZ490 motor into WR360 chassis

My mates building his own Air Cooled dream bike

Serco rebuilt YZ490 motor fitted into a late model Husky WR360 chassis.

Probably the worst-engineered, most impossible to jet, unsuccessful, large 2T bike engine ever built. Now what'll we do with it? I know! Put it in a flexy, old school chassis with shitty brakes that's hard to find parts for!

Love it!

Can he put a 2LT-E Toyota diesel into a Lada Niva next? You have to love these mad scientist types. A mate of mine, Dave, is building a saw bench for firewood blocking, he asks me if a 350 Chev will drive it...ummm yeah Dave, 300HP should do it.

Ol' mate has a collection of WR360s ( '94s through to '04s), so this is just a low cost (?) shirt for googles exercise. He sent the 490 engine to Serco in QLD to get the head mod, barrel ported etc
When I used to ride with him back in the 90s and early 00's I was constantly repairing his WR360s on the trailside as something was always breaking/broken and he just kept acquiring 360s to keep at least one bike operational

About time DBW had their very own .....Tim the Toolman Taylor! Here in Oz.
Best episode was the time he ShoeHorned a small block (as the yanks call it) 350 Chevy
into his ride on lawn mower!
After all the fun and std one liners were done ....out come the line of the year ...

PS Hey Nutty make sure Dave installs a damn serious Splinter Guard. Won't ya !

Sorta what I was thinking, also it doesn't then qualify for VMX or anything useful.

Is "Airhammer" because they ping and carry on once the crankcase heat soaks.

Dunno, when the Yamaha WR500 came out in 92 one of our group called it “The Airhammer” and after one 15 minute ride I could see why 😄
