Hi All I have a newly acquired 1995 600SS and upon checking it all over I have noticed that the air box top has no inlet rubbers. Question 1: Should I be worried that such is missing? Question 2: Does it make any difference? Question 3: If the answer to the above questions is "yes"; then does anybody have any spare ones for sale (cheap!).
Doesn't matter at all, in fact a lot of people remove the airbox lid and just cabletie the filter in place. You would prob need a Dynajet kit for this tho', just to richen it up a little.
No worries at all, as I said you will want to be getting more air in there than the two original inlets allow.
I let him know if he finds he needs them, I have two new trumpets........when I fitted them, they completely screwed my Dynojet setup....
There's a good pic in the carby ss parts needed.... thread of the top off air box, same as mine but I am dyno'ed and K&N'ed. If you do cut the top out don't cut it too shot at the front because water will run off the tank and into the air box, not good
Mine has had no top for as long as i have had the bike, 5 years + a previous owner had it removed at some stage in its life, i ride in all weathers and it lives outside, it has never had any effect on how it runs.
does seem to vary - bike to bike. My 750SS was 'semi' cut down and I had no water ingesting problems but I never used it in torrential rain. My 900 Monster suffered badly on the other hand and I ended up adapting lid for 4 'snorkels' which has stopped the water ingesting problem but also doesn't restrict the Dynojet set-up. As Phil (Ghost) says, it's possible that above set-up would work just as well with 4 holes* and no snorkels and I might try that on the next bike. *just to confirm - only beneficial when used in conjunction with larger Dynojet needles and jets. (added to keep AL happy )
Before the OP goes hacking his airbox top around, he should establish whether he has a Dynojet kit fitted and which Stage kit at that. If the bike runs well without the trumpets fitted, just leave the airbox alone......hacking it will more than likely upset the carbs and the way it runs. AL
Just to clarify, I only have the trumpets missing, not the air box lid. But I will check to see if a Dynojet kit is fitted. But I am presuming so as the previous owner ran the bike "as is"; and when I ran it up before beginning to strip it to clean etc, it ran OK.
I'm taking a bet that there is a Stage 1 Dynojet kit fitted, because that is the normal reason to remove the just trumpets and leave the cover alone (although I have the same with a Stage II kit, but I also have different zorsts). Just check your plugs for colour when you have done a 25 mile fast / hot run............If they are OK and it ticks over and pulls nicely from low revs, then it isn't worth cutting the airbox top.........but if you put the trumpets in, I reckon it will give you massive flat spot each time you wind it on quickly. AL
I have a stage 2 kit in mine, and in box K&N. I was advised not to cut the air box back too far because of rain running off the tank and into the air box, if its not a problem then i stand corrected.
you are right to be concerned as this can be an issue but it might take running during persistent, torrential rain before it becomes a problem that can't be ignored.
