That yz490 engine is badass! I have a friend here blew his yfz450r engine to hell then ported that 2 stroke yz490 engine and replaced the 450r engine with that. I rode it once. That was enough. Insane!
Thanks Todd, same to you.
I just watched this the other day.
I've never ridden any of the big bore 2 strokes. Id like an 81 YZ 465 to restore for sentimental reasons. My first bike was an 81 YZ 80. Here is the thing, I Know I'd ride it and I CANNOT be doing that *s-worde anymore.
I thought you already were a stroker....
Raced them for 8 years and no problems until Humpty Dumpty fell and broke his femur in 1996. Borrowed a bike in 2001 and took seventh at the national amateur day at High Point. That was my last ride on a dirt bike.Don’t do it you’ll hurt yourself
Mine was my first build at 18 years old. 60 over 4 bolt main 350. Stock 194 heads with 3 angle valve job. Full roller timing chain, comp cam 268 cam, 1.6:1 Comp cam roller tip rockers, Edelbrock performer intake and 600 cfm carb. Headers. It dynoed at 296 hp. Stuffed it in a chevy Monza where a factory boat anchor 305 had sat. 2000 stahl converter and a stout shift kit. I should be dead with the *s-worde I did in that car.
Even though ours was uber mild, my wife's taste is still off. She never lost it but has noticed all her food is less flavorful and she can't detect salty.
383 strokers are fun when built right. I build one for a 68 camaro. (Not mine) Made over 500hp on the dyno had 150 shot of nitrous on top. Super fun.
I broke me lower back a local motocross track. On a quad. My new bike at the time was at the dealership getting its break-in check up.
Thanks for asking,
Whats land up in your hood going for these days?
