IMO, the kit works great as long as you do the following:
- Install the Cross/MMWS P+C, gives you a caber ring set and much better performance.
- Use OEM piston pin bearing and piston pin clips. The bearings are only about $10 from a dealer.
- The Chain adjusters are a PITA. Even if you go OEM, often addl work is needed. I often get the Huztl parts to work, but the HL Supply adjusters seem to be better quality and very reasonably priced. You still often have to shim the shaft of the small gear, and re drill the hole in the metal cover larger (it does not fit over the adjuster gear. I cut a thin strip from the foil that comes on my bar oil container to use as a shim, seems to be working well so far.
- If installing w/o base gasket (recommended), grind Cross Name off cylinder to clear flywheel, and enlarge lower part of hole in plastic for spark plug.
- Control levers are often "iffy". Make sure you lube them well, and work them in a little.
Other than that, I've been real please with how they perform for cutting + milling.
