Well I managed to find a BST carb and unmodified air box for cheap, and the PO gave me the stock exhaust with the bike.

So I got all the stock stuff bolted on today and took it for a test ride. Man, the bike just runs sooooo much better. It revs up much quicker, in fact I almost ran into the back end of my buddy not expecting it to accelerate that quickly. The bike just runs much smoother and the quiet exhaust is just a relief after that noisy assed FMF can.

It's actually easier to ride, especially doing some climbs on some pretty rutted out and muddy hills. With the pumper carb I seemed to always have to shift a lot more trying to keep up the revs. With the BST I can lug it and the bike will still pull. I have a feeling I'm going to see an improvement on mileage as well.

The only down side is the obvious increase in weight, but this is a pig of a bike anyway so I can live with a half dozen extra lbs.

Previous owner gave me stock exhaust, as it currently has a Two Brothers exhaust, and I'm still unsure of jetting mods. You inspire me to hurry up and put stock exhaust on and see how that feels.

The 2009 I recently got had carb mods. Drilled out slide, different jets, needle, cut open airbox. Kientech header/ mid-pipe. GSXR can. Air screw.

All it did was make more noise. Stumbled on take off.

I put the standard jets back in the carb, standard needle back in, covered up the airbox. New slide with one hole. I kept the air screw and exhaust mods. Installed a K&N filter.

Runs like a champ now. Smooth and no stumble on take off. It used to 'hic' after you rolled the throttle on for a tad. You had to rev it at stop lights and let the clutch fly to overcome this.

So easy to ride now. I have a 16T front with OEM rear. It topped out at 100mph showing on speedo with me sitting upright behind National Cycles screen. Also a one foot square TT 41L top box on the rack...not bad.

My normal speeds will be speed limit and a tad over, so I'm good to go.

It sure likes to go around bends I'll tell you that. It holds the line nicely and inspires confidence. You have to keep it on the boil and with the 16T front that means lower gears for tighter bends. Coming from a BMW R1150GS that ran like a diesel big rig this is a change of pace for me. The lack of torque takes some getting used to....but I love it! I thought it was a bit buzzy on the freeway with the 15T front, and I do some freeway so have to compromise.

Thanks guys!

I'm interested! If the cover's as well made as the Warp9 levers on our two DRs, we'll be able to forget that little issue forever!

With just a 14 tooth countershaft sprocket my DR will climb great and slide corners in the dirt easily,the only way a DR will keep up with a 530 is to toss both out of a plane and see which falls faster.

I've got a Q4 on my KX 450F and it is actually QUIETER then the stock can. Of course there were reports that guys failed tech because the stock cans on those 09 KXF's were too loud.

Mine came with the 14 tooth CS sprocket. Never wanted to go to the stock 15 myself.
