Has anyone had luck with engine mods on the new KTM 250 SX-F? Anything you have done that you can share pros and cons? Cam, high comp piston?
Thanks dudes!
Thanks dudes!
I'm sure most reputable shops are doing work on those by now. Although "All New" I have porting, exhaust and a vortex on my 2013 with great results. Vortex was a amazing addition.
Like Ricko stated above... Chad pumped out some great HP/Torque numbers using the stock valve train on a 16 KTM!

If you are looking for the fastest and most reliable 250 SX-F motor possible, look up Tom Zont Racing... Check 'em out on social media, there's nobody better and doing the things he's doing at the moment. Master of KTM's right now.
The Shop
Not so much as a hard hit but just a meaty feel from gear to gear.
The fact that the Vortex allowed it to rev so much further is amazing on a already rocket of a 250f. Most good engine guys can mod to your desired preference/specs.
Zont? I wonder if that's the same Zont family that painted my helmets in the 90's under "Paint Can Designs"?

Id say go with DCR dan knows his stuff and is making some killer bikes at the moment
I've often felt the same way. thinking "meh...this squid couldn't use all of a 93 CR125"
But that same squid on a 450 will turn faster lap times than he will on the 93 CR125, will he not? so should he ride the CR125 out of "principle", or should be get what HE is fastest on?
There's more to making a fast motor than what the dyno sheet shows.
I don't need a rocket ship or factory motor, just want more bottom end. I rode my buddies 2015 Yamaha 250f and really liked that feel. Just want to see if I can move some power around.
Dan did some work on my 250 and my 350

Just being obtuse because it's early.
Does seem like it's possible to get good results from fueling rather than really stretching the motor... duel injectors from quick wrench sounded promising with a get ignition....

The torque curve is more important to me.
There is another guy that's a high dollar consultant to professional race teams in Nascar and some moto (just a little bit in moto). His name is Bob Wirth. He' s in N. Cal. Hayward. Near Oakland actually. He's a legend in the motor world. He does consulting to teams on engine packages and designs. Some of his stuff was on a well know moto team a few years ago. You'll know the teams name. Bob is an unreal resource of information. He even consults with Fuel companies on mixes. He's worked for some of the big 4 moto mfg's as an engine consultant.
He's that good. But you've never heard of him......
I do like the idea of fueling though, look up the Quick Wrench KTM 350 tested at Vital. Those results sound promising because you're not fluffing with cams/porting etc... just optimisation.
