TDC Liked a reply to forum topic KTM 150SX Aftermarket Head and Porting

I swapped my STIC Super X PWK onto a buddies 125SX and he came back saying it felt like a 150, but right off idle had no need for clutching. The design picks up a lot more fuel at low rpm signal and is in a cooler vapor state. The performance gain will pull harder than a $4k+ race build, as told to me by a race dad that A/B'd with his boys otherwise stock bike.

The top 3 should be able to keep their gap with a staggered start. Let them go one at a time based on the gap they had when the red flag flew.

I came here to say Keith Bowen but you beat me to it. In 1984 on factory Yamaha he started just pinning it through the whoops. It was a hold on and pray style but was the closest thing to skimming whoops that we had seen. It blew everyone's mind and was a big focus of attention.

Nice story but not true. Keith Bowen was the 1st consistent skimmer.

That was during my era in the early 80s I believe it might’ve been Keith Bowen

There are so many great choices and I am certainly biased towards US riders. That said there are so many world enduro riders that have Mx and Trials backgrounds that certainly should be on this list. Juha, Sala, Peterhansel,Ericsson, Tiainen,Knight, Watts, Ahola, Aubert, Price and many more.

AMA regulations require the OEMs or their distributors to declare the motorcycles they intend to race ahead of each season ( section 1.1 in the 2022 rule book). The mandate states that at least 400 units must be available for sale to the public, with a minimum of 200 bikes required to be in the US by March 1 and at least 400 units by June 1

Lectron will be soft off the bottom. Maybe that helps traction and is less tiring as well. If you want more beast mode grunt and over-rev that matters, a used Keihin and STIC metering block is the ticket. Eventually this will be a no-brainer, but until then, power is left on the table.

Since you mention a 300 kit, it seems like you want more power than a well tuned carb or pipe provides. I know a 250SX rider that installed the new STIC Super X carb and he is digging the much stronger and wider powerband. Said he's not getting pulled by 450's any longer and slips the clutch far less. The Super X should give you the stock peak hp level 1k rpm earlier and extend it 1k-ish rpm on the over-rev. Between that expect an additional 5-6 hp. The cast Super X is more akin to a race tuned package...

Hi Mate This story warms my heart. My 15yr old son sustained the exact same injury in feb this year. Shattered C5, fractured C6 and now has a full fusion of the C4,5 and 6. He had movement of his left ring finger first, then down to his toes and then eventually some movement in all extremities and can now get around on crutches but has long days in the chair when required. Reading your story gives us hope that he may recover even more over the next few years as hes young and fit and has an amazing attitude...

It is a tough road, I was paralyzed in 2020 and I have recently gotten some feeling back in my legs. Vibrations, things to that affect. Just hoping things unitive and stem cell can eventually be afforded.
