Found a end cap, cost me a bit but works xclnt with six suppertrapp plates in it.Took it for a 10 mile ride and it runs xclnt thru the whole rev range and pulls xclnt with the jetting I am using, a 180 main, shimmed neddle 25 thou and the 58 pilot.Just enough sound to not sound like a washing machine and not to much to be to loud,on to the next thing.Would like to go with a lith battery but cost is quit high,or 520 chain conversion,next will be a front spring conversion as the stock setup is junk and change the footpegs.you can buy alloy folding pegs on ebay for 20 dollars,then all you have to do is make a almost triangler template out cardboard that matches your footpeg brackets and cut a piece of alloy plate of your liking in thickness.Then cut it and drill the mount holes and then drill the hole in a place of your liking for the foot pegs.cheap to do and only about a hours time in work if you take your time,its a good chunk of weight and costs little.Trying to cut weight without cutting any tabs or pieces off the frame.Wire wheels ? who knows but this a fun bike and I have not riddin my 2007 Suzuki sv1000s but one time in the last 6 weeks tells you how much fun this little thumper is
