  • In this video I inspect the cylinder and piston on my 1974 Yamaha DT250 to try and determine the cause and solution to my low compression.
    Enjoy!

    Time for a bore job! Lets see here... stock bore X stroke (70mmx64mm) is 246cc. Boring it to 70.75mm will bring it up to 251cc. I think that cylinder would be a good candidate to practice your porting skills Chris. 😜

      I agree. I will try my hand at porting. I have had a bit of a time finding a .75 piston kit.. looks like I will be going to 71mm and most likely use a forged Wiseco piston.

      I thought .75 was a strange sized overbore when you mentioned it. I've only seen overbore kits in .50 increments. That's an additional 2cc of displacement though. You know what they say... "There's no replacement for displacement"! 🤣@@CK-Cycles

      @@UncleMeatMan yep, the is (or was) an OEM .75 but Wiseco goes straight to 71mm. Gonna be a great bike!
