Dual plug heads are of benefit more at high rpm, the dual ignition source enables higher compression ratios and higher rpm as the dual flame front promotes faster burn times and quicker cylinder pressure increases. The doubling in the number of spark plugs requires a similar doubling of...

Amazon.com, Kawasaki dealers, public library.

Probably don't need to tune it as much as give it a general service check and clean-up. Should have been winterised anyway if you are in a cold part of the world and the main issue is to flush the fuel system, replace all fuel with fresh, fit the battery (that you have had on a quality...

Contact Kawasaki with the part number and find out the availability yourself. Kawasaki are generally very good with parts availability, I have no opinion on why you are having trouble. Good luck.

Just get a workshop manual. The information is copywrite for fifty years from initial publication so you are potentially encouraging illegal activity. As this was the base model original Jet Ski they were popular, simple and cheap with a reliable single cylinder engine that was robust if not...

They are the original thing, with a long and successful run. It will possibly have an uprated ride plate, intake scoop and impellor already fitted - few did not as the handling improvement is big over stock. If the engine has aftermarket pipes/other mods this can complicate things a little...

Yes. My last one was a heavily modified '88 model. 250 KX fork springs, white power rear spring and re-valve/re-gas, extended stinger cone and pipe mods to internal baffles for grunt/mid, Staintune race muffler 40% longer, split perch levers, Nicad battery pack, additional coil windings (ran...

Yep - stick to 50:1 TCW-3 or better lubricant. Engine is un-burstable if maintained.

No free manuals - they are copyright. Very cheap ones on E-bay and Amazon though. Lots of libraries have service manuals. Good luck.

An itemised receipt is a reasonable thing to expect when spending that amount! All new parts (pistons, rings, bearings, seals, paint) machining and cleaning of block etc., all labour and testing. Why won't the shop give you a cost breakdown or honour the warranty? Your first stop is the...

The opposite. The further a mono hull leans the more it will slip, so if you hike out and get the boat flat you will go faster and slip sideways less. In most dinghy classes slip is increasing from 10 degrees of lean - flat is fast as any serious racer will tell you. The sail foils will work...

Very unlikely, and as illegal as heck. All service and workshop manuals are copywrite protected - someone owns the information and licences it to you when you buy the manual. Only information considered to be valueless commercially is "free". Some illegally downloaded manuals have been proven...
