Hey guys first post in years (precrash) on arboristsite. I've had a makita 6401 for years and finally pulled the trigger on the 79cc oem top end. This was my first saw rebuild. I've only made a few cuts with it, but it seems to be a beast. I'm looking forward to getting a few tanks through it and see how it performs. I'll try to add a few pics of it wearing its new 24 bar and chain. Thanks for all of the great information.
