KZrider is more than a website. Its members comprise a community of KZ enthusiasts dedicated to encouraging and preserving our sport and passion for Kawasaki Z, Z1 and KZ motorcycles. We pursue our passion because we enjoy it, not to make money from it. To that end, except as provided below, is not a place for you to solicit sales of any kind. No member is allowed to refer to their own business, or any business to which he/she is associated, through the discussion forum or personal messaging system (U2U). Be aware, the U2U feature has been abused in the past. If any member solicits an unwelcomed solicitation through the U2U system please report that solicitation to the Administrator or Moderators promptly.
Business names are permitted as user names ONLY by paying advertisers, which paying advertiser's business name will be changed to a non-business name upon cessation of advertising. Such prohibitions include but are not limited to images with a watermark, logo or other reference to one's own business.
There are four exceptions to this policy:
1. An item may be offered for sale in any forum where there exists reasonable expectation of being welcomed by another member who has previously expressed a need for that item in the thread ("cold calls" and "door-to-door" solicitations are prohibited). This exception applies to regular members and paying advertisers. Of course, the classifieds are still available but are limited to consumer-to-consumer transactions.
2. Each member is allowed a simple link ( in their signature, which link shall include no description of any kind.
3. As allowed only in the Vendor forum where paying advertisers may refer to their own business and include images with a watermark, logo or other reference to their own business.
4. In general forums, paying advertisers may refer to their own product or service ONLY to correct a misstatement or misunderstanding existing in the thread about the paying advertiser's product or service. A paying advertiser shall not include any negative comment about another vendor's product or service. Paying advertisers are subject to the same rules and sanctions as are all other members, applied equally to all, without exception.

You may not post libelous or defamatory messages or materials, or include links to such materials in your postings. You may not post messages that are obscene, violent, abusive or designed to harass or intimidate another individual. Pornography, Warez, or any other illegal transactions may not be posted or included in members profiles. No blatant nudity.

Don't use racial, ethnic, or gender slurs, religiously derogatory comments or any other personal discriminations even in jest. Use of slurs needlessly offends people - whether or not they're a member of the group you've insulted. Respect others' religious beliefs and culture. Recognize that others have religious and personal beliefs which may differ from yours. Stay away from political debates. Keep the language and behaviour appropriate.

When you post a new thread, please give users some idea of what it contains in the title. Thread titles like "Help" or "Check this out!" are cheap ways of getting users to look at a thread they might not care about, and would not have clicked on had the full title "Help, I need credit card numbers!" been used. Furthermore, it helps stop multiple threads on the same subject. When starting a new thread, describe the content of your thread clearly in the 'Subject' line of your post. Don't use vague subjects. Use descriptive and specific subject lines. This helps others decide whether your particular words of wisdom relate to a topic they care about. For example: "HELP!!" is not an appropriate subject and neither is "My bike doesn't run".

That cap lock key wasn't invented to help you get your message across. Messages written in all caps are annoying, hard to read, and loud.

Please look for an existing thread on a subject before you post one about it. Chances are good that your question has already been answered. There is a search feature on these forums, use it. Starting topics that have already been answered in great detail is a waste of everyone's time. Look to see if information you're about to post has just been posted by someone else. Then go ahead and post.

The Technical Forums have different sections for a reason. If you're not sure, use your best judgment. 

Cross-posting is when you post the same message multiple times in various threads or forums. We only need to see it once guys. 

Keep threads on topic. If you've got something completely unrelated to say then start a new thread. Unresponsive solicitations for consumer-to-consumer sale are prohibited as being unrelated and off topic, but solicitations for consumer-to-consumer sale may be posted in Classifieds.

Adhere to the same high standards (or higher) of behaviour online that you follow in real life. In real life, most people are fairly polite and law abiding. The same rules of behaviour are expected on any list.

or introduce a relevant idea. If you've read enough threads, you've already learned how annoying it is to go through "Me Too" posts. A "Me Too" is a post that says "I agree with what the other guy said" and otherwise does not add to the content. If you have a comment about someone else's post, tell them via U2U or email. Generally speaking, unless it concerns the entire group and is within the group's stated purpose, you should reply only to the author. Avoid replies or responses to the whole list of yes, no, or "I agree!". This is meaningless and you too would be annoyed to open such a message.

If you are a new member, introduce yourself by posting to the New Member Forum. While it's nice to welcome a new member, only do so if they have posted in the New Members forum. There is no need for 50 welcome posts in a technical forum thread.

Please don't start a topic that is directed at one person that could be put into a U2U to them. If you have a message for one or two posters, use U2U or email.

Images & attachments may be posted as long as they are not explicive or offensive. Images are limited in size to 2mb. The Project Forum is for members' rides only and is an ideal place to document your rebuild.

Don't even start them, they will be ended, quickly, and you'll find yourself on the short bus. Flaming: Personal attacks in cyberspace can be particularly vicious. Flaming is the rather nasty art of attacking others on a personal level.

i have seen people use desiel, tranny fluid kerosene that sort of thing but you will have to take it apart anyway because most times they are seized because water got in the cylinder somehow and if that has happened then the rings will be rusted into the bores so even if you get it freed up and could make it run again the cylinders and rings will have been damaged so you will end up needing a bore job at the very least.

That acid and aluminum are a very bad combination!! It will rapidly attack any aluminum it comes in contact with.

PB Blaster, Marvel Mystery oil and even used Diesel engine oil will be much safer.

How it seized would influence the manner in which it is freed.

Did it rust from sitting?

I use trans.fluid and gas mixture and let it sit a few day before attempting to turn it over .works for me everytime. but if water got in the clys is a different story as long as the motor had carbs on and exhaust you should be good...1/2 and 1/2 with the mix..
