GS1150 ES Makeover Project

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

I am putting my hand up as being responsible!!Greetings

it's not about blame, unless you are being paid for doing it.... well done !!!( but yeh I also blame you lol)

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:

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.

Greetings

yeah... the pic under the airbox pic is def a blue seat m8

sparki - hey we have a Londoner in our midst. Living in Canterbury they call me a DFL as I am Down From London. Not seen you before.

Not sure where you are getting the idea that I have a blue seat. Have a look at the photos in the blog for this bike (see below). The bike arrived with a modified black seat and I ended up buying 2 new black front seats for it. Plenty of these available on eBay.

Edit: just looked at my own blog!! Yes the new seat does look blue. Seems to me that is because of a problem with the camera. Let me look at it in daylight tomorrow.

Greetings

quick question... the front seat you bought... are you planning on getting it recovered to match the rear? the reason i ask is that my front seat needs recovering too... foam is all good but the cover had split a little from use over the years (original blue seat as yours).... I want to keep mine the std blue as the rear is still in great condition. so i guess i'm asking... would you consider swapping seats with a few ?? your way (only if you're planning on a re-cover ).

bit cheeky but i'm struggling to find another std blue front seat to be honest. that one's cover looks good

cheers

Motor Dies When Throttle Opened

I posted this is the carb section:

http://www.thegsresources.com/_forum/showthread.php?t=220278

and I have since checked one of the fuel levels in the no. 1 float bowl by jamming a piece of plastic tubing up the drain plug. It seems that the fuel level is pretty near to the top of the bowl, so lack of fuel being able to get up the main jet can't be the reason it dies when the throttle is opened.

See it in action here:

Air box is sealed and throttle slides are working.

Help!!

Video shows air filter sitting on top of the airbox, not inside. That could be part of the running problem...

Starts When It Has Fuel - What A Surprise

Spent hours over this thing. Checking all the sparks and whatnot. Rookie mistake: not enough fuel in the tank. Despite the float bowls showing me they had fuel in them.

Went and got some more fuel and she runs:

Not running nicely. Like the other bike that I did; very lumpy (needs carb sync) but also would not rev above about 4 - 5K. Just dies when you get it up there. That would suggest main jets. Now I did take that extra washer out from the needle that was below the little circlip. Has that done something?

After setting the idle speed it would hold a steady idle without any choke but would still not rev freely.

Anyway, I am dead chuffed I have got it spinning. Sounds like there is some cam chain lash so I will adjust the manual tensioner at some point if someone tells me how to do that.

Starting with Carb Cleaner

I tried all the electric test and could see no sparks at all. I brought the bike into the dark garage and I could just see that they were in fact all sparking.

So why would it only fire on one cylinder?

Let's try something that should help it along - carb cleaner. Not because the carbs are dirty. They are beautifully clean. But because carb cleaner is very combustible. Let's see what happens:

So it does work.

Maybe, just maybe, there is insufficient fuel getting through. I have checked that all the float bowls contain fuel and that the petcock is releasing juice in the prime position. But maybe, when the tank is on the bike there is just not enough fuel getting in.

I'm off the get some fuel.

Greetings

The new plugs should help, try it as is with the new plugs, maybe it's all it needed...you can snip each lead by a 1/4 inch and screw back into to each boot as well just in case there is corrosion there as well.

hope you find the solution....

Yes you're right. No throttle required on a properly set up bike. This one has a really stiff throttle cable (going to be changed) and is only firing on 1 cylinder with 100% choke. I was thinking it might be flooded so trying to blow it out with some open throttle.

I've got a lot more work to do on this. Got 4 new plugs today as there was no continuity on one of them (don't even know how that is possible). Got to check leads and coils and whole wiring harness really. I hate electrics. Give me a spanner any day.

Greetings

You should not need to give her throttle to start her up, choke should be enough to at least get her going...

did you take the plugs out, and clean them ? if not do that for all, and once you have them out check to see if each one sparks

Your so close. Coils, caps, wires and plugs?
