YAMAHA 550 YICS MANUAL


Hi, Anonymous the vast majority of service, parts, 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 around $10 sometimes more and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, then there is eBay where you may be able to find what you need at a very high price because of its age and rarity. Most of the "FREE" 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. To download your manual please click on the links below. Good luck and have a nice day.

I have just bought another engine for my 1982 xj650,it is supposed to be a 1980 engine but it has ycis on it,i am not sure what this means,will this be ok for my bike,thanks


Hi Dave...I think you mean YICS, which stands for Yamaha Induction Control System. Back in the day this was the latest & greatest in modern technology, this engines are considered classics now.
Yamaha introduced Yamaha Induction Control System in 1979 as a fuel-saving engine system in 4-stroke motors...It was ahead of it's time actually. These engines burn cleaner, get better mileage, and produce more power. It will work fine in your bike.

I hope this helps & good luck with your bike.
