Basically any AL frame is not next generation. Generally

Watched a few videos on your channel. Interesting tuning for a 350 feel. Very nice videos.
Just curious, i was planning on running my cr500af at vintage days this coming year. It’s a 95 motor in a 2008 450r chassis. What class would i even run that in.

That's a good question.....

I don't know. Might have to run in modern. Ama vintage days cutoff is 98 or 99 and no AL frame if I remember correctly.....
 

We just bought my son a 65 there. $2400 off msrp.
 
what is the deal with the newer ktm's? are all they all junk or just early vins or certain cylinders that you can tell externally if its one that was bad or not? i'd love a fuel injected 125. I really wanted a 150 but I know they skipped it for 23/24, so the choice is a carbbed older model or get the 25 and not sure a 25 is in the budget for something that mostly sits in the garage collecting dust.

or stick with the trusty yamaha.

I was looking at a discounted 2024 XC125 and asked my local dealer about the KTM/Husky/Gas Gas 125 problems. He said there was a recall issued and KTM honored the rebuilds even out of warranty. He also said if the motor did not fail, the recall was a replacement of a remapped ignition. I guess they have not had problems with the 2024 and newer bikes. Not sure if this is the entire issue but he said the combination of fuel injection (but KTMs were not fuel injected in 2022), advanced timing in the mapping, and running lean was causing the connecting rod failures. His advice was to always use the richer of the 2 maps (i.e. not that standard map).

Well, the real issue is the Crank bearing. I own three 125 Sx's. One 2021, and two 2022's. The 2021 was fine until we rebuilt the motor and put a brand new OE Crank, bearings, seals and gaskets. We used a Vertex 2 ring B piston which was required based on our measurements. The crank bearing went at 11 hours. We did the same thing again. We double checked the squish, we used VPT4 and mixed it 40:1 to give it a little more lubrication and the oil was Motorex 2T and 4T in the trans. That crank lasted 9 hours and sucked a finger bearing into the cylinder that blew through the wall and split the cylinder. The real issue is not the CDI, it's the lower crank bearing and web tolerance. The con rod is simple to tight and excess heat is causing the cranks to fail in various areas. But KTM won't take responsibility for the bikes so they have chosen to de-tune the bikes to lengthen the life of the crank. But qualifiers wait for nobody, so we're keeping our CDI's and rebuilding the OEM cranks to our specifications or just going with another crank such as Wossner. Just my opinion of coarse but it's the truth lol.

I didn't buy the XC and instead bought a pretty decent 1 owner '07 RM125 for a quarter of the price. Gives me a new project and a bike I can work on. Bonus is I saved the taxes, freight, dealer set up, and doc fees (? for a motocross bike?) that were half what the 07 RM125 cost me.

Project photos soon.
 
2023 125 project turned out sweet! Still got some tweakin to do, ran out of time before he headed South. He said she ran pretty good.
