If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

hey guys, going to get my new (to me) '85 gs700ef tomorrow:). just looking to get some basic info about it ahead of time.

first, are there any manuals online or do i have to buy one?

second, are valves bucket or screw?

third, since i know nothing about the bike i'm going to do valve adjustments, do i need a gasket or is it like the honda xr series (no gasket needed) and if i do need one where's a good place to get it? shims are decently priced on z1 so no problem there.

fourth, looked at the RR listing by matchless but couldn't find any info about the 700. anyone have any info about sourcing a new one if mine is in the crapper?

fifth, is cam chain tensioner auto or manual?

thanks guys any info will help. i'll be surfing the forum all night tonight to get info before i tear into it tmrw.
 
1. BassCliff has an 83, would probably be close: http://members.dslextreme.com/users/bikecliff/
2. already answered
3. Yes, you need a gasket. OEM are vastly prefered; aftermarkets are just not up to snuff. I had two in a row disentegrate on my on the road. Embarrassing and time consuming.
4. I would assume the same would work; I have not heard of any that were not compatible, especially the 4 cylinders.
5. Auto.
 
Some Add-ins & corrections :)

1. With the 700 you have to lift the crossed over oil pipes on top of the head to get to the screws.
The bolts holding these pipes are special & no longer exist as new so be careful with them (same with the pipes). I had two of these bolts that were broken due to overtightening. Luckily they spun right out. I have a spare set if you need some.... Rest of the procedure is similar.

3. The Gasket is rubber so no you DON't necessarily need a new one. However if it's the original you probably will need one (or you'll have to use some blue gunk). New ones are about $30. The bolts that hold the cover on are also sealed by rubber coated washers. Again if original you will probably need new ones but if fresh they can be re-used over & over. Don't overtighten as they go down to a positive stop on a shoulder & will snap.

4. Yes. I had a Shindengen FH012 on mine. Any Matchless lists will work. The 750/700 of this era (83-86) had an awful RR & if yours is not shot I would replace it anyway. Failure mode is usually over voltage (if grounds are good which they usually are on these bikes as it already has an RR direct back to battery ground wire as stock). First sign is blown headlight... & you risk the health of the CDI & battery too. Not sure if there is room for the Shindengen in stock location, I relocated mine for other reasons.
 
yup planning on replacing the RR.

any advice on a reputable source to get the head gasket?

and thanks for the manual koolaid kid i can't imagine their that different. either way that's a good website.
