Yamaha YZ325 Two Stroke Mike Alessi Build - Motocross Action Magazine

#motocross #action #dirtbike #motorcycle
Motocross Action Magazine tests Mike Alessi's ESR Yamaha YZ325 Two Stroke at Glen Helen Raceway. Mike qualified for the Monster Cup Supercross with this bike. The only two-stroke to qualify for any kind of Supercross event in probably over a decade or more. The ESR 325cc powerplant. You won’t believe the affordable price to big bore your smoker. Josh Mosiman had a fun time riding the ESR big bore. The power was spread out and incredibly smooth. Check out what the Motocross Action Wrecking crew thought of Mike Alessi's bike at Glen Helen Raceway in Southern Calfornia.

YZ325 Two Stroke I love two strokes two strokes!! Manufacturers need to start building two strokes again 125-250-500 a gate full of highly tuned, race gas running 125 or 250 or 500 two strokes with the smell premix in the air.!! Brrraaapp!!

Have you not rode a 4-stroke before? Because if not, once you get used to that 4-stroke you'll see why the sport went virtually all 4-stroke. That is, despite the environmental impact.

I owned two YZ250's ,an F and a 2T back in 05. Just to see what my mates and every other bastard on earth was bangin on about , but I always enjoyed the two stroke more. So I sold the four stroke and lived happily ever after. But it took more than a decade of resistance before the tide started coming back again. You were a bit of a crank sticking with the two strokes but that suited me fine.

@@davidklimmek3192 Yamaha will never update the YZ the guys who designed their 2 strokes have left or retired almost 2 decades ago when they switched to four strokes like Honda. They keep casting parts as they can still make a profit but none of that will go to an updated 2t. Either buy Ktm or hope Yammy will keep tossing simple bolt-ons to their vintage Yz's.

i cant imagine how that feels.. insane amount of power

[@marvelaturraz5405]

The opening shots got me to reminiscing.... It was around 1990, and I was racing 250 intermediate class at Mammoth Mountain. Ted Boyesen was in my class. I think it was moto 2. Anyway, he and I had met earlier that day, because his bike was the crispest, fastest bike I'd ever seen there. He had his jetting perfect, and all the extra goodies which made his bike a rocket. He probably holeshot both motos, but I wouldn't know because my bike was way low on power and by the time I got to the top of the start hill, I was toward the back; from 30th to last place. But I battled to the front and Ted was there, running somewhere in top 5. I banzai'd the big downhill to gain back the time he pulled going UP that damned long hill, and then also gained on him in the next few turns. I was pulling up alongside him to pass in some whoops when he swapped hard, and he would have wrecked except his rear end caught my front and knocked me sideways so hard I instantly body planted into those whoops myself. But his hitting me saved him from crashing, and he went on to finish somewhere near the front. I didn't catch back up after that, as it was a hard wreck which rocked me and I'm pretty sure bent my bars and probably broke a lever. I don't exactly recall though. But I do remember that Ted Boyesen was a really nice guy, and I've always wished I could be mad at him for that because it ruined my dream of winning or placing in the top at Mammoth. And he totally took me out!! ;-). I could only afford one financial splurge like that per year to do something like go to Mammoth to race. So that really was a huge bummer for me. But that's racing. And on the other hand, I'm glad that my being there, in the perfect spot for Ted to swap into, kept him from having a very rough crash himself. I just wish I'd been about 2-3 feet further ahead, so neither of us would have crashed. I never got to see him again after that.

[@davidkeeton6716]

I've got one, '71 Bultaco Pursang Mk5 350, actually 326 with stock bore. And yes low pipe as most were back then. About 33 hp. The 350 Astro that year had 50 hp, different cylinder porting and chamber, still only 10:1 compression.

I would have liked to get a squint at the innovative power valve.......those damn things are always dirty and it sounded like this wasn't a problem. I still like the yellow on Yams....wish they were still that color.
