Oh I'll fancy it alright, but I have a small window to get everything moved out of the old workshop and container and into the new one. Then sorted and set up ready to start earning again because on top of the increased costs there's a period of not earning a penny for over a month to contend with. Worth it in the end, but it's going to sting for a bit.

Ok mate,i'll leave your entry in though in case you fancy a bit of down time.

I'm not sure, I think they're the same set up but can't remember if they are whether the head side ID is the same. It's a very long time since I had anything to do with a GS1000.

Maybe GS1000 rubbers might work or are they bolt on?

Fitting a set of VM 29 Smoothbores to a 16v GSX head. Are there suitable rubbers or is it a case of pinching down the existing rubbers?

Just as confirmation @PaulmI definitely won't be coming as I've just had the call about the new workshop and I should be getting the keys a week or so before then. So I'll be running around like an idiot trying to get everything moved and set up.

If it's a 2002 (mk2) you'll probably have to swap to mk1 inlets too as the later ones (bsr carbs) have a different spacing to earlier gsxr/mk1 bandits (bst carbs)

Cheap 38's is going to be way better than 36's

Got a chance to get a set of Rs38’s on the cheap side got a 2002 gsf1200 with pipe and pods RU2922 and 4* Advance.. will 38 be alright or the 36s be better?? TIA….

Short video of it idling and a little rev. Probably still a bit fat https://youtube.com/shorts/rJWhrDFmxP0?si=OPjBRL2MNHBxBtLJ

always pays to double check cam timing

I couldn't get all this to add up with the low compression. Like why would it be so bad if the piston rings where new,valves lapped.... so I checked timing and... bingo! Cams where off. I don't know, maybe the crank moved when they where installed I redid them and boy did it make all the difference! After some fettling with the carbs and idle i had it sitting at 1200 for minutes! Damn steady! I'm delighted! Will sync the carbs tomorrow, recheck ignition timing and compression. Take a test ride

Nice looking bike that is. Fairing bracket is for mk2 faring.

at last work has started on my desert rat fighter its an 89 1100 with busa swing arm and tl1000 wheel and a 750 k6/7 front end just need a front wheel discs for that front end (as money allows obviously) hope to get it done by mid summer fingers crossed

My friend had exactly the same problem ( on a single cylinder engine ) and went through 3 carbs before he stuck my "leak down tester" on it. Exhaust valve leaking due to poor condition valve seat and carbon build up. Pointless trying to set carbs if the engine is not in good fettle. Who said anything about a blocked oil filter ?

having an air filter on or off won't make much difference at idle with the bike stood still, the compression isn't the best but it should still run fine at that as they are all fairly equal. a balance might help if they are way out. but as Jonny said if you can, try another set of carbs.

Just the standard set of four gauges with vacuum hose. Neat tip. Will try that.

So pulled Brian out from the back of the garge, as its 4 weeks to the welsh classic Bike festival and track day, thought I d better see if it runs after 7 months With a new battery and some fresh super unleaded it fired up eventually, went done the by pass and back using my universal number plate This just reminded me how small and uncomfortable it is!! Its great and i love it but its just to small for a fully grown adult!! So I have decided that this will be the last run out and then ill let it go to someone whose child sized Anyone want to come and have look at it, ill be at Angelsey for both days 25/26th may.

I've heard many stories of bikes running poorly with pod filters (espceially single pods), but not at idle. The draw is so low it shouldn't matter. Plus there's no airflow issues because you're stationary at idle. I run an 1100EFE motor in a GS750 frame and also use K&Ns (twin ovals) and have never had an issue like this. Maybe the guy with the 82 GSX hadn't rejetted the carbs to run without the airbox... What are you using to balance them? Might be worth putting some gauges on when it's doing this and see if one carb is dropping when warm.

I do have another set of cv carbs on the shelf from the older gs850, but they are in no shape to be run as they sit now. They need a complete overhaul. Maybe I should just order some parts and get to work on them. They weren't ultrasonic cleaned as my cleaner is dead (just ordered parts to repair it though). But all the jets are new, and I made sure to blow brake cleaner through all the circuits to check that they where open. Which they all where. I also posted about this in a classic motorcycle group on facebook over here and one guy replied that he had a 82 1100 gsx that would behave exactly the same! And his problems disappeared after refitting the original airfilter box. I don't have the standard box, is there some other way to simulate this? Socks over the air filters? Sponges inside? Taping off a portion of the inlet??

This doesn't sound to me like an issue caused by compression. If it were me, I'd try another set of carbs on it first. Sounds like you've already done all the things that would idenitfy the usual issues. If it works with different carbs, you know it's the carbs. You might have some sort of blockage in one of the fuel circuits responcible for idling. It take it you have completely striped and (ultrasonic) cleaned the carbs?

Looks very similar to this Harris Gs1000. Sadly not my bike just out of my picture collection. Tis a beauty and nice that they kept the GS 1000 motor . Looks like `H` section Dymags, could be wrong

Gonna do another compression test today and try to add some oil to the cylinders see what happens

We need bigger OSS banners.

Long stroke 750 barrels, pistons, and head, bolt on power, whilst keeping the original bottom end. No messing with DVLA that way. or, keep the 600 head, so carbs and airbox all line up.
