By registering at the KZrider.com community, you agree to the following terms. KZrider.com reserves the right to remove any posting it finds unsuitable. Members who refuse to play by the following rules will be excluded from the discussion board.

PRODUCT OR SERVICE ADVERTISING IS STRICTLY LIMITED
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 KZrider.com 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.

There are four exceptions to this policy:
1. As permitted in Classifieds (consumer-to-consumer transactions).
2. An item may be offered for sale as a consumer-to-consumer transaction in any forum where there exists reasonable expectation of being welcomed by another member who has previously posted in the thread ("cold calls" and "door-to-door" solicitations are prohibited).
3. Each member is allowed a simple link (somesite.com) in their signature, which link shall include no description of any kind.
4. Paying advertisers are allowed to post in the Vendor forum.

KEEP IT CLEAN
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.

BE CIVILIZED
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.

USE DESCRIPTIVE THREAD TITLES
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".

PLEASE DON'T SHOUT!
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.

HAS IT BEEN POSTED ALREADY?
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.

WE HAVE SECTIONS FOR A REASON
The Technical Forums have different sections for a reason. If you're not sure, use your best judgment. 

DON'T CROSS-POST
Cross-posting is when you post the same message multiple times in various threads or forums. We only need to see it once guys. 

STAY ON TOPIC
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.

CONSIDER THE IMPACT OF YOUR WORDS BEFORE POSTING
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.

MESSAGES SHOULD CONTRIBUTE TO THE TOPIC BEING DISCUSSED
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.

WELCOME TO KZRIDER
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.

U2U IS A WONDERFUL FEATURE
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.

TOPIC: Fixing small cracks on aluminum engine parts

Fixing small cracks on aluminum engine parts 5 years 6 months ago #266979

I pulled off my cover to my stator, and BEHOLD! THERE WAS A FRIGGIN CRAKE AT THE VERY BOTTOM! I had just started to degrease the engine because of caked oil and dirt everywhere, and I feared that maybe there was a something more serious going wrong with the engine. Good news, there isn't. Bad news, there's a crack on the stator cover....How can I fix it with out getting a used stator cover? mig or tig it, jb weld....what is something that will work very well?

i've had good luck with jb weld in the past but depending on the size of your wallet i probably would look for anew or quality used one as ive never had any luck welding crack up in oil soaked alloy plus the extra heat can and often will warp the gasket surfaces so then you would have to machine it true again.if you jb weld it give it lots of time to cure and try to do both sides of the crack internal and external.

Here's my three cents. The best stuff I have ever used to repair or patch alum. is called Devcon. It comes in two cans, mix them together and it starts smoking. (it makes you feel evil) I have seen other people patch cases and even make new fins to replace old broken ones. It comes in three different types. Alum, Steel, Cast Iron. People have even used it to patch blocks on tracters. The only hold back is it costs about $25.00 or so! (yes you can get a new cover cheaper) But the two cans will last you for a long time. Maybe not if you blow up alot of stuff.

devcon does work well we sometimes use it to raise the floors in the intake ports when porting the reason i suggested the jb weld is that it's readaly available and it does hold up quite well to oils and heat and it is easy to work with [filing and sanding] and would cause any distortion like welding would and also everybody has heard of it or used it at some time in there lives.

Never used liquid, it's a paste. I don't about permatex...It could be that high in price. Just put that out there for those who don't know.

Not to highjack the thread but do you think that devcon would hold this very good? would it be sturdy enough to fix this?

twfields79; I would have that welded. It won't cost much, and you won't have to worry about it breaking again. Ed

Not brazing. That piece looks like aluminum, but I can't tell for sure. If it is, aluminim can be welded using Shielded Metal Arc Welding (SMAW) - also known as stick electrode welding or Tungsten Inert Gas (TIG) or Gas Tungsten Arc Welding process (GTAW) - also know by old guys like me as heliarc welding. Welded aluminum is very strong. It shouldn't cost much to have that small piece done, but call around first to get pricing. Ed

you can actually mig aluminum too....I've done it a many of times on live all trailers and trailer doors...good penetration is a must, and you have got to know what your doing, and have the right gas mix which you can find on the internet....

twfields79 "Are you sure heliarc welding will work on cast aluminum?"

I had the entire cast aluminum transmission/engine case heliarc welded on my old BSA after I broke it (please, don't ask how, it's embarassing) and never had any more problems with it. I suggest you do a little web surfing on the subject to get a fuller picture, but here's one site with a description:
