    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. 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.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. 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.

GS1150 ES Makeover Project

sparki - I think you are right. I would sure do a swapsy with you or whatever. I will take some pics of it so you can determine if it is up to scratch.

Who Messed With My Needles - Ooopps!

Who Messed With My Needles - Ooopps!

See My GS1150 Blog for bigger pics.

I took the carbs off to see what the blazes was going on:

All the bowls had a decent amount of fuel in them:

Even though little tangs bent quite a bit:

There were still within spec:

Could the needles be a problem? They are quite low in the emulsion tubes:

I took the needles out and compared them to another set of carbs I have. This is what I found:

All four needles had been assembled with the spring on top rather than under the circlip. I am putting my hand up as being responsible!! I had never taken needles out before this rebuild and they sprung apart on me so I was not able to see the order of the parts. Should have checked the workshop manual. Or had the PO assembled them like that? He just might have ......

Here is proof that the problem is solved:

Very good ! Sounds like it's popping when you let off the throttle. Does that stop when it warms up?

Morning :) - that's great news indeed m8. Of course I would be happy to pay for the postage in getting it to me ;) - if you could send a pic or two that'd be great, and I can do the he same for you? My email is sjparkinson@gmail.com

Did you mention that you bought a few front seats or was it just the one?...

Cheers and thanks again,
Steve
 
Oh My Camshafts Cooked

Oh My Camshafts Cooked

Now it seems the carbs are working, I figured I would have a look at tappets and see how the cam chain was looking with my manual cam chain adjuster. I was horrified by my cams:

P1110256.jpg


When I prodded the lip on this lobe, it came off:

And this one was gouged out badly:

Was this oil starvation? It was only on the right hand side of the engine that the lobes were damaged.

What does this say about the rest of the motor?

Very disappointed with this now.

Idling too much can ruin cams. Best to get some new web cams 0.340 and nice followers if possible.
 
Cheap oil and left idling on the sidestand for far too long, I'd say.
 
Is it bad to have slides so black like that? I cleaned mine a day ago and they were fine. I just never seen a slide so black before. What would happen if you don't clean those slides?

The 1150 slides and some others have a black coating on them.
 
just replace with another set of 1150 cams... either on ebay or contact Roger Upperton to see if he has anything that'll do the job... http://www.uppertonracing.com/

he does a lot of work with these engines, is a great person to talk to and will set you on the right path. it shouldn't cost big ?? to sort imo.

just as an fyi... if you do find them on ebay make sure they're not out of a german (or french??) motor as the power was restricted via cams to 100hp
