$Hi, Damien_bug the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee of $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download.

Hi, Xim1645 a regulator-rectifier on a motorcycle converts alternating current to direct current. The reason you need one on a bike is that the bike is equipped with an alternator, which is just a device that takes power (in the form of rotation) from the engine and converts it into alternating current (AC). Think of the alternator as a type of generator. Now AC is a fine source of power for lights, but you can't feed AC into a battery or into a fuel injection computer and expect it to work.
The rectifier's job is to convert this AC power into Direct Current power so it can be used to charge the bike's battery and otherwise power all the 12 volts (DC) devices on your bike (electronics, tachometer, etc.) It's worth mentioning that generally a rectifier is combined with a voltage regulator, which makes sure the alternator doesn't generate too much (or too little) power/voltage. If your alternator were to generate too much voltage you'd risk overcharging the battery, burning out your bike's electronics, etc. And if it generated too little your battery would slowly drain (this is the most common failure in a voltage regulator) I bring this up because on most bikes they tend to combine these two functions into a single rectifier/regulator. It is also worth mentioning that all rectifier/voltage regulator must be physically or electronically (by wire) grounded in order to function properly.

open the clucth cover and check if rod is installed

also how was it packed solid/friction/solid/friction

while open check clutch basket for ruff edges where solids plates ride should be smooth

1998 kawasaki... | Answered on Jan 23, 2016


this is normal. The heat from the engine is no longer being circulated by the water pump, this causes the pressure to rise. The coolant is expelled into the coolant tank. The coolant is drawn back into the radiator as it cools. If the coolant level is low when checked ( bike cool ) then there may be another problem. Over heating due to stuck thermostat or blown head gasket. Be sure the coolant overflow tank hose is not cracked or leaking.

check your throttle cables,may need lubrication,especially near carb linkages,clean &lubricate,no wd-40.

1998 kawasaki... | Answered on May 13, 2014


Several possibilities, including, throttle not returning to idle position due to bent or damaged cable from throttle to carburettor.This cable may also need lubricating with light (thin) oil. Idle setting on carb may need reducing. Finding the trouble should not cost a lot if you require someone else to dignose. If you have a work book for your vehicle (recomended), just go through the troubleshooting section for that problem. It could be an easy fix yourself at no cost.
