Dr. Pappa Breaks-In his Yamaha YZ250 Top End with Apex Head at Golden Pines MX, Mississippi

I hope I get as good on the bike soon!

Why did you switch back to a 250, what didn't you like about the 325? Thinking about doing a 300 kit soon and just looking for some personal anecdotes.

[@Dr_Pappa]

Great question. I did not dislike the 325 at all. It was just way more power than I needed. It would get me exhausted because it was so powerful that it felt like it was trying to rip my arms off all the time. The other reason which is the actual reason why I switched back was because the customer service from the company that made my big bore kit was terrible and when it was time for me to do a top end I got frustrated with not being able to get in touch with them and having no support or information, so I went back to stock and I'm loving it. Apex head makes it so good. I wouldn't have another YZ without an Apex head.

Which dome is installed?

[@Dr_Pappa]

SX and I love it, even for tight woods, very responsive and great all the way from the bottom.

Proper break-in! What expansion chamber and silencer are you running? Bike sounds sharp and clean

Thank you! I have a PC Platinum and 304 Silencer, love them!
