85cc Makita 7900 / 6400! 54mm piston and cylinder installation on this smurf Dolmar

The blown up Makita 6400 gets an 54mm top end! This will make it an 85cc 7900 big bore. in this video I glue the cylinder down and give some tips for reassembly on these 7900 6400 7300 series saws.

I just got done putting the same cylinder on my 6401 you can really feel the difference awesome upgrade

Ah nice work dude! Yeah though I think this one has a bad coil.

Nice work walker

[@walkerscountrylife]

Why thankyou Mr. Walker! A very happy new year to ya

I just converted a 6421 to a 7900. I used an OEM top end and kept the beautiful white top. They’re great saws👍🏻

[@walkerscountrylife]

Hey Doug, thanks so much for taking the time to comment on my lil channel. Did you do any port work to that beauty? Getting an OEM top end here was $$ and not many around, so went aftermarket BB.

[@IndianaDoug]

@@walkerscountrylife yes but not a lot. Just enough to bump the compression. She makes a great worksaw.

Put the covers on it will look good, looking forward to seeing how she cuts.

[@walkerscountrylife]

Ok that's it settled! She gets the black covers!

[@walkerscountrylife]
