My 91 900ss has no deiceing to the carbs, however the ever resourceful MR AK has some bits and I am after a photo or details as to how it should all fit together.
Haynes manual only mentions it but has no information.
Thanks Kev.
Or a complete unit no longer required would be even better :smug:

I always heard that those carb heaters never really helped.

I mean, the engine has to be hot for the oil to be able to heat the carbs for easy starting. BUT, to get the engine hot enough, you have to have already started and run the bike. :roll:

IMHO, better solution is to properly jet the Mikunis or step up to the FCR's

Just looking at the options at the moment. I have the addertive for the petrol which I will be trying this weekend. Its only if I do another Europe trip, dont want to be caught out in France.
Your coments are very wellcome.
Thanks Kev

kev -my thoughts and ramblings - this is what i have found - the worst cases of carb icing occurs when the air is very humid and cold (when it is foggy) this is i believe is because it isnt the petrol that affects the carbs it is the cold air drawn thru the carbs that is the problem- when i ran an open airbox with k+n and stage two dyno jet, unless i was accellerating hard the bike was spitting and popping all the time--i replaced the open airbox with the standard cover and instantly made a difference also after a few miles i stopped lifted the tank and directed the trumpets on the airbox at about 45 degrees outwards so as to lose the direct "ram air" effect this improved things to the degree that i could tell the difference in the running of the engine- finally i replaced the k+n with the standard filter and what a difference that made hardly a miss and the engine picked up a lot smoother all this using the FST at 50:1-- so to cut a long story short i have reverted back to my stage1carbs and a std filter set up for the winter, the bike ran well today but it wasnt as cold as it has been recently-- i'm currently thinking of fitting the carb heaters(that have been sat on the shelf since last yr) to the stage two carbs just to see how much difference it makes- although i have found that the FST seems to be coping well and i can live with the problem as things are----thoughts that i have had, albeit pie in the sky and a bit wacky is to add an oil cooler to the top of the airbox to create some sort of warm air induction system- like they do on light aircraft to alleviate induction icing--also i have noticed that when the carbs are suffering from "icing" the float bowls are dripping with condensation i wondered if a couple of those wrist bands that tennis players use would help wrapped around the bowls????:D

Dave I went out Sunday morning with 200ml of Silkolene addertive in a full tank, and guess what---------------------------------------------------------------------------------------------------------Yep thats right it iced up like a advert from Icelands !
To be fair it has all the bad points that you mentioned above, open box, KN filter large main jets etc.
Next time I will try more Silkolene and see if that does the trick ! Oh and another suggestion is higher grade fuel such as Opitmax or similar.
The call to uncle Al (AK) is looming fast.
I can ride it when its iced but its no fun what so ever.
Bloody roll on summer.

sorry to hear that your still having problems kev i'd definately up the ratio to 50:1-- have you had the carbs balanced recently? this may be contributing to the problem if they are out of "synch"-- optimax or equivilant will help definitely help, i have noticed a difference using different fuels---just another thought on induction heaters i wonder if the heating elements from some grip warmers could be utilised in some way?????either wrapped around the inlets or placed in side the airbox-i wonder:eureka: maybe someone around here may have some techy knowledge on that one:D the ones with the adjustable heat control would be right pukka

dseered your not helping much are you;) fell off me chair when i saw that---i reckon your gaff is a bit like "men behaving badly"part 2 mate:sing:

I have a 600ss and had carb icing issues, I tried PSFT and it made no difference at all, no matter the mixture ratio. I then got Nelly at cornerspeed to fit the carb warmers and have not had an issue since. IMHO dont mess about with additives and just get the carb warmers and end the problems.

As an alternative viewpoint to phils, I have carb warmers on my SL. They're as effective as a chocolate teapot. ProFST on the other hand works like a dream.... I also found using optimax or equivalent helped too.

Here's a picture of how the carb heaters are fitted if that helps...

ProFST & Optimax 1st Kev, then if not working.....

phill - a positive reply that they work!!!what air filter/box were you running at the time??? may be a case that they work on the 600ss and maybe not so well on the 900ss's? fiscus are you running open air box etc??

I've got a K&N with a vented airbox lid.

I'm sure Derek looked into putting heater tape (the stuff you use on exposed pipes to stop them freezing) around his carbs/manifolds. Don't know if he actually did it in the end but might be worth a U2u.
