Carb Question - I am missing something - SV650.org

fizzwheel · 13-08-06, 10:23 AM

First off. Thanks to Viney, The Squid Meister and Bigape for advice. I have finally managed to get the carbs off my K1 SVS. I've also after alot of huffing and puffing got the choke plunger screws out. I've got a couple of questions.

The small brass plungers were stuck in the carb body which was why my choke was stuck on. They seemed imensly stuck and didnt want to slide at all. I used a small pair of needle nosed plier and removed the brass plingers. I've cleaned them up and put them back in and they seem to move OK now. There was alot of rust on the plunger springs as well. Is it OK to use some coppaslip or normal LM grease on the brass plungers so they dont seize again ?

Also I think I'm missing a bit off the front carb.

When I took the carbs off there was a small bullet electrical connector that wasnt connected to anything. It would appear on the back carb theres two electrical connectors. ( Red arrow in the picture above ) One a flat connector and the other a bullet type connector. On the front carb the connection for the bullet connector seems to missing. ( Blue arrow in the picture above ) What does this do and is it important. I'm thinking that it might be a connector for the carb heaters.

Thanks

Fizz

Yep its the carb heater. I think this issue came up before and it was said that they are so useless that you would not notice them if they were gone.

I agree with TSM. Although it's nice to think that they are there and working properly, they are quite crap and you probably wont notice any difference.

As for the grease in the plungers. Not the best idea. However, The reason that these plungers tend to rust up and seize is because moisture and rain drips down the choke cables to the little splitter box and then on into the plungers themselves.

Open the splitter box and insert plenty of grease. This should keep the moisture and rain away.

That's a really good idea, wish I'd thought of it

If the springs rust enough they can snap, my front one popped and jammed the choke on, quite annoying.

OK next stupid question

Why is that not a good idea.

I'm guessing that the choke cable either moves the plunger into a whole that shut or closes depending on the position of the choke lever. So that when the choke is on it lets more fuel through so it runs richer. If theres grease on the plunger might it gunk ?

Apologies if this sounds like total rubbish. I'm doing my best

I'd say you answered your own question.

'Cos it's a fuel valve - the grease will be washed away in no time, no harm in having a wodge of grease behind the plunger, and shoved up the cable a bit, that'll stop the any corrosion on the cable assembly too.

Yous welcome!
Master, I like that - almost as much as Emperor - but not quite.

Carb heaters: If they're there they may as well be connected, but you wouldn't miss them if they weren't
