Bike will BARK. But you can’t be any geek off the street to ride one. Gotta be handy with the steel.
Can only dream of 2 strokes coming back
The Shop
Start at about 45 seconds and he says they beef them up and add extra power and the factory forks when talking about the 250.
I’m saying it doesn’t take much to make an insanely great engine even better. I give a small parts list and you read that as broad stroke sweep KTM under the “showed up with stock bikes” rug.
Responses like yours are why Vital is really rough sometimes. Jesus. Chill man.
KTM doesn't have " race engine's for their 2 stroke line up? You don't think they have those motor's gone through , cleaned up and running to perfection?
Sorry to break it to you....but a stock 250 / 300 doesn't pull OR sound the way those bike's were. In fact , there was a thread on here , that a friend of mine chimed in on , and mentioned the name of the guy who does in fact do motor work on these specific bikes! He should know.....he fucking worked for them!
Whatever displacement they were running, they're running primo race gas so they can up the compression and run a tighter squish which produces more torque, which is what you want on a track like that, HP alone does not make the best braaps. The biggest issue that holds a 2st engine builder back is detonation. With unlimited race fuel and a 45 sec run, that's not a problem here, (unless you're Pourcel).
You want bulk torque and rapid throttle response. The standard KTM expansion chambers good for a grunty mid range though you can bet it's cleaned up inside and you can always modify the header length depending on what characteristics you're chasing. The stock Mikuni is an awesome carb, just a little finicky to get the jetting spot on. That's not a problem when you're testing with factory mechanics. Add the V-force reeds, Akro silencer, open airbox and a few 'minor' things like a factory ignition setting, cleaned up and matched ports and cases with factory port timing and you've got a 2st that will bark.
Especially when you've got some of the best at twisting a throttle.........
And the chassis is developed and been revised to the extreme like 5 times since the Yamaha has changed a thing?
We can go on about what we read in reviews on two strokes but it's a different story when a pro is on one.
Good god. The KTM engine has been better than the YZ for almost 10 years now and they are still developing it. Anyways, it was rad to see RV and RD race again.
Edit: It seems like the KTMs were 300s. Well then the big advantage makes even more sense. My point still stands though.
Pit Row
Anything else, they'll figure it out.
Handicap class racing needs to be done away with - Equivalency!
I'd say at worst, he's 2 seconds slower, worst case. And that might just be out of fear of getting hurt.
It'll never happen, but who knows, he sure put the hammer down at RBSR. Dude can ride the piss out of a 2 stroke!
And not everybody rides a 2 stroke like Bubba. But I'm guessing you knew that already.
The teams/riders spoke on the broadcast about re-jetting once the temps dropped for the evening runs. The main is only full throttle and they weren't running the bikes full throttle throughout the entire course. Don't want to start a debate but jetting is way more crucial on a 2 stroke, there is no way around that fact. Any dyno will prove that.
