It seems I need to change my drive chain for a 1200 ZRX kawa... Since it has a high torque engine, which brand/kind do you recommend?

It's really dependent on the particular saw's requirements.

Old saws used to need a 25:1 fuel/oil ratio, and modern saws as little as 50:1. Somewhere in between these extremes is a safe bet. Use a little extra oil in the fuel for new saws in the "running-in" period or after a rebuild. If the spark plus fouls, then lean it off a little.

More important is to use good quality oil: name-brand products are usually safe, and usually recommend the appropriate ratio on the packaging.

Chain oil is another, different product that has a separate tank for lubing the chain, bar & sprocket. Usually at the front end of the saw, the tank requires refilling with chain & bar oil at the same time the premix tank is filled. It's usually a high-tack oil, with anti-throw properties for use on the high-speed chain. Name-brand products are recommended, with vegetable-based oils preferred to mineral-based for environmental pollution reasons.

Use a 20W50 weight synthetic or petroleum based oil that is rated for use in diesel engines. You can look on the container to find the API rating. It will have an "S" rating like "SH" or "SJ" and also a "C" rating like "CG" or "CF". The "C" rating is for use in diesel engines and has the high pressure additives in the oil that Harley recommends. As for the brand, there are many different brands on the market. Amsoil, Royal Purple, Redline, and Mobil V-Twin are a few. Any one of these oil or H-D brand oil are very good lubricants. The key to long engine life is clean oil. Make sure your change your oil at least on the recommended service intervals. And don't forget the primary and transmission oil changes.

Good Luck

Let it warm up set the idle and that is when it will idle correctly.

hi is this the ecentric chain adjuster on the swinging arm?,

Any good quality chain saw 'bar' oil is suitable and it does not need to be an expensve brand either: it is highly recommended that you use a specially blended chain saw 'bar' oil but in emergency you can you fresh 'thick' (e.g. older) car engine oil but don't make it a habit as your chain and bar will wear off a lot faster!

I don't think so -no. That seat is model-specific.

A service manual is a valuable tool with an aging bike. I suggest the dealer/mfr. or Clymer books. In the meantime, go to the library reference section...646 stacks should have what you need.

The ZRX has CDI ignition. The CDI ignition timing is fixed and can not be changed. A "tuneup" means you change the oil and oil filter, install new spark plugs and new air cleaner, lubricate the cables and chain, adjust your mirrors and then wash the bike. That's it!
