generous neighbor gave me this bike while I was ironically walking my other bike home after it died on me. he said he thought it had a cracked head and was leaking compression. my gauge says the opposite. is it even safe to run a 2 stroke with compression that high without it dieseling?

Exactly what it says is this correct I noticed the second I put the ring in there the gap is too big is this correct

2025 KTM 350 EXCF - WP XACT closed cartridge forks.

I bought the tools I think are needed and new springs from race tech to respring my forks and rear suspension.

The bike has maybe 4 hours on it, so I don't think I need to change the oil which is pretty intimidating process tbh. I just want to swap the springs themselves and that's it.

My question is, can I just keep the forks upright the whole time, pop off the fork cap and then pull out the inner cartridge and swap the springs/adjust preload spacers and put it back together? I do not need to remove the bolt on the opposite end of the fork (the bottom) to access the springs?

Chat gpt says the springs are at the top of the fork not the bottom, but I think that is incorrect and it's instead like shown in the picture above from this video.

It's a 2005 KTM 125 SX.

I just bought a brand new piston and my measurement tool is lost. However these look fine to me. I haven’t filed them down or anything. These are straight from wiseco.

Looking for a bigger bike for my son. This one is local. We went and looked at it. Started right up. Sounded good. Doesn't come with a stand. Back sprocket is shot but seller said he has one ordered and will replace it. Bottom dollar is $1800. Is this a good deal or should we keep looking? This is in central Oklahoma.

thats the bolt to my manifold to where i put on the carb, it screws in perfectly but theres a little gap on the side even when its fully tightened, i havent rode in 6 weeks, tried multiple spark plugs, tried 2 different wiring harnesses. and every time i kick it over it sounds like its about to start but just gives a tiny pop and shuts off

I took my bike to a local shop and asked about lowering. He said my bike had already been lowered by about 30mm. I have short legs, and with something 1" tall under my foot, I had a lot better balance and confidence. The question is, am I severely hurting performance or safety by going an additional 20mm (50mm/2" total)?

I don't go too crazy, but I'm pushing myself to ride more technical terrain. I would sacrifice some ground clearance for the sake of not dropping my bike because I can't touch the ground
