Should the throttle cam 'spring back' once all is cleaned? Mine is still very hard to move.
Lots of photos and labels needed for this I think as don't want to forget something.

Thanks for the advice so far peeps...

be very carefull as sv carbs dont like being played with and all the bolts are made of cheese just dont do like i did and snap one

Nicky,

Yes the photo shows the cam, which I imagine should be fairly easy to move and I guess should spring back to a closed position.
I started taking the carbs apart last night and two more screws rounded off at the front....*^%$*&&^!!!!
Before I began stripping them, they were soaked all over with WD40 etc, cleaned(ish) and then for about 20mins I attached a 12mm ring spanner to the nut on the cam and just moved it back and forth, lubing the linkage all the time. Still no joy. It wontmove without a spanner or a fair bit of force.
Surely it must move fairly easilt, because isn't the sprng on the cam what makes the throttle grip on the bars spring back to a closed position?

I think I'll buy a set of used carbs and fix mine later because the linkage seems seized....

Any suggestions peeps??

Well as you said it should move very easyerly. And yes the spring is what makes it spring back.

One thing i noticed when i f****d my carbs was that the cam (bit you are having problems with) would not move at all unless i did what you are doing with spanners hammers ect. This was because i hade bent the bar that gose throw the carb. The one the butterfly sits on.

Im not to sure how i manged to do this but i think it was trying to remove the cheese bolts.

But another thing i dont understand is you were ridding and this happend dont understand how you could have put that much pressure on it

See the threaded ends of those bolts that the heads were like cheese? Did they look blue? . . The reason for them not coming out is that they are blue thread locked . . An impact driver may have got them off but considering how delicate the carbs it would be difficult to use one! I feel your pain im going to have to clean them up before i refit mine during my bike rebuild.

All a bit strange really...got the bike dropped off at my house in Mid december (the day before the bad snow came)from a friend and it hadn't been ridden for a couple of months. The snow stopped me riding it and then in early feb, I took it out and the throttle wasn't working properly at all. The choke was what was keeping the revs up and I was sort of fixing it as I rode and then on a straight just away from my house, the throttle moved and locked fully open, and at the same time the little plastic lug on the inside of the RH switchgear snapped and made the throttle assemplby loose and locked on!!! managed to grab the clutch and killed the engine, before limping back to the house.
I reckon it was bound to happen at some point as the bike appears to have been neglected somewhat (to say the least).
Still...live and learn

The things that are made of cheese (so far) are just the screws holding the front carb choke plunger assembly and the screws holding the front carb top cover on. I've not come accross any bolts with thread lock -YET.

I'm sure that if all the screws and bolts were made of 'Seriously Strong' cheddar all would be ok!

I've just bitten the bullet anyway and bought a set of apparent working carbs from Fleabay, so I'll clean them and add on the new M5 stainless allen cap bolts then fit them and get on my bike...during which time, I can slowly fix my original set and find out what's wrong.

Right then,

I've just tried to fit the new carbs after a thorough clean up...but when re-fitting the carbs to the bike, I've managed to break TWO of the heater connections (both on the rear carb...they are a brass bolt with a hard black plastic insert and a brass extension, onto which a connector attaches). I snapped one, then took it off and re-fitted a replacement from my old carbs (the new set had one broken already). This one snapped too.
Mega problems lining the carbs up and once it was eventually fitted, the throttle cables were really tight, despite not being fitted to the throttle tube on the bar. Then the best bit happened...whilst re-attaching the cables to the throttle tube, the f*&^%ng thing broke!!!!!! AAAAARRRGHHH!!!!!!!.

Anyway, I now need a couple of new brass heater connectors (just in case) and a new throttle tube.

What do I do??

Anyone got a throttle tube for a 2002 curvy they want to part with?

Help please as my bike is becoming the bain of may life...and I've only ridden it twice in three months.

You'll have to weigh up the cost of replacing the parts that are broke against buying another set of bodies, i usually have a look at svparts to keep an eye on how much the whole part is. I'd consider if its viable to replace, get the part number thats fookt from the microfiche and email the local suzuki garage to get a price on it and weigh it up from there.

oh yeah, and consider the repair difficulty.

Managed to fix both broken bolts and have had a new throttle tube (well new to me anyway) shipped over from Germany from a member of this site...cheers Nils!!

Just waiting for the part to arrive and on my next day off will take a chilled aproach to bike repair looking at things that can break and steering clear of them!!!

I sit in my garage dressed in bike kit willing the bike to fix itself!!!

Use the time to do some homework and making notes, planning out and also some time to de stress over it. Your taking you first steps to fix your bike!
