Default Stupid tank foam

My top tip today is... lift up the tank and rip the foam off the underside.

I had a mare for nearly a week last year when this came loose and I couldn't understand why the bike wouldn't go over about 60, the mad thing being that it misbehaved the same every time. The foam was falling onto the air intake and blocking it off. Stuck it back on, sorted, then the other day had to make a quick getaway from a numpty in a Beemer, and once into ban territory it was really struggling. Checked the carb balance again (just done anyway, and was still fine, no surprise), and noticed the foam had come loose at the front edge, so I think it was flapping down in the wind. Yanked it all off as far back as the back of the intake. And now, well, let's just say it was back to normal!

Say no to the foam! Free yourself! Cast off the shackles of induction noise abatement! A first class ticket to Dottingham!

I've just said this somewhere else so might get told off by admin (sorry). I just got rid of the foam on mine, and discovered that Holts Damp Start dissolves the adhesive big time!
Lift the tank, stuff a rag in the air intake to keep the crap out. Spray on loads of damp start, let it soak. Then use an old bank card to scrape it all off. Would recommend gloves though because it goes a bit sticky.

this thread leads me nicly to a few questions (espicly as my sv should be returned to me this week) what is the reason for the foam in the first place? and what advantages are there to lifting the tank on spacers?

The only reason anyone's come up with is noise reduction, which makes sense I suppose. The advantage to raising the tank is that it removes a restriction point, the airbox lid is fairly close to the top of the tank otherwise. But I'm not sure if it makes any performance difference with standard parts. In fact, if it did flow much more air, that'd be a problem with standard parts as you'd run lean.

Factory Pro did a load of dyno tests, apparently, and came up with 17mm as the ideal spacer size.

I think the manual says it's for induction noise reduction. My curvy( the blessed) never had any on when I got it.. And that curvaceous Eileen, well she makes a racket when she sucks!!
