I have a 05 kx250f that is super hard to start when cold! It will bumpstart with ease then start easily when warm. I checked timing and it was way off. Havent had a chance to try and start it but would that be a reason or would it be valves being too tight or too loose?
Hi there.question I have 2004 250x with big bore kit on it.when it’s test run out last year left it till few months ago I’ve done the carb jets a cleaned it all in a ultrasonic cleaner.was told by hot cams that valve gaps should be 28 thow and 12thow.I’ve done this a bike still won’t start up a used to start right up.any help please as to what it is why won’t start.
Re-shimming will only be a short term fix , if the bike has been run with zero valve clearance the valve faces will be worn and once the surface material has gone the valves wear out even quicker . I would pull the head and renew all valves , very common issue on this model .
I'm curious why your seat looks like that is that defective foam or is that on purpose and deliberate to have a big lump in your seat at the end ?? Just looks like whoever did your seat did a real fast sloppy job 🤦
Excellent delivery when it came to specs and procedures. This is the 3rd "how-to" video I've watched and definitely the most straight to the point. Cheers
This is a well thought out ( how too ) and makes it much easier for someone who's just starting out with bikes! Great tips aswell 👌 I don't even have a bike yet haha. But I've subscribed after this one! Great stuff
I have the exact same bike ..same year.... my valves need doing soon and having watched your vid it don’t seem so scary any more..... subscribed.... cheers
The easier start cold than hot part is very true
Good Video!

My ktm 525 was always in spec. 2 stroke much easier to work on

😢looks like not easy job
I recently got a valve adjustment and I had fresh oil and air filter and it was still very hard to start could it be my spark plug?

Wow. I wish you could explain every mechanical project I do. The tips to look out for and details are spectacular.
I had no idea on how valves worked until I saw this video thanks man!

You made this so uncomplicated, thank you. Subscribed. :)
Your video was great help for me to start working on my 150...
Much apreciated the video exactly what i needed to know about my bike with the same issue.
This video has given me a lot of confidence and hope.
I'm a 2T guy but this video really helped me with a friend's bike - Thanks for your exceptional how-to!!!
