I’m getting a new 2023 kxf450 this summer and I want this exact same racing setup. Know anyone who can help ??

Can you talk about how it runs on the track? Did you change gearing? Was it dyno tested? Is it too much power to control or does it retain the smooth characteristics of the stock engine? Thanks

I’ll be doing a detailed ride review and breakdown of all my mods and how they affect the bike in the near future!

Now get the pc linkage and the suspension will be godly

Why u4.4 over t4? Jw I honestly don't know

Жыл бұрын

In my experience I’ve had better luck with u4.4 than t4. T4 is a much cleaner fuel though and better for the average racer.

@John Holka MX I have a 21 ktm450 factory edition. I use t4,love the smell lol. But never knew which is better

how much horsepower that beast make?

@JohnHolka

Жыл бұрын

I’m estimating 63. The stock 450sr makes 60.5hp. So with this thing having slightly higher compression, an aggressive port and epoxy job, 5 angle valves and a vortex ecu, it’s gotta have at least a couple extra horses lol

I’d beg to differ, sir. I’ll put whatever stickers I want on my bike. Thank you very much. 😊

Whoever ported that head didn't have a flow bench. Or even a piece of sandpaper to smooth that out. Besides behind the valve doesn't look right, no neck. Now well best of luck hopefully you don't run into any of my motors at the drag strip ...

I know money is irrelevant to racers but that bike is too nice to be thrown around the track like a rental😢 the bike would be perfect without that exhaust tip damage

Haha the carbon tip got slightly damaged and a new one was like $150, so I just epoxied it. 😅

It ruins anything rubber though. All oxygenated fuel is rough on rubber.

@@keithpeterson6108hmm that’s interesting. Been running O2 fuel for years, but I’ll keep an eye on intake boots, etc. I imagine it’d be horrible for 2 strokes then, since raw fuel actually contacts the crank seals.🤔

@keithpeterson6108

Жыл бұрын

@John Holka MX Yeah, it's rough on float needles, all the o-rings in the carbs & fuel pumps. It's mostly anywhere the fuel is held more so than where it contacts. All the gnarly stuff evaporates off the intake tract & inside the engine. So it's not as rough on bigger items like intake boots & crank seals. I used to run it & a few other "flavors" from VP but don't anymore. I ended up having to replace all the rubber in my 2stroke carbs (buddies as well). It was such a hassle to drain it out after every ride vs the little extra jam it gave. In my efi bikes, I didn't want to deal with pulling the tank & purging the system, so I never ran it in those. Put some in a red solo cup sometime, it eats the cup! Lol
