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.

Sounds to me like the TM-40 wasn't properly jetted.

Spent 3 days messing with the jetting on the TM-40. Took 5 minutes to get the BST properly jetted.

Motolab, You just made my day. I guess I am not missing anything. I really could not figure out how that brass piece worked with the plastic part that I have, but, then I have never been able to set a digital watch either.

FMF's are loud,maybe their newest Q model is quieter but Id hate to have to listen to the noise all day on my DR,I have the older Q muffler on my 530 and it runs great that way,but can be heard a ways off.

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'm still debating the muffler issue. I've found a 2nd hand Gixer pipe but it's working out to be $400+ once I've factored in the mid pipe etc, and that's a lot considering the end result will be a 10 year old frankenstein exhaust. For that price I could....

Looking at the FMF Q4 on the procycle site... so how quiet is quiet? Does anyone have recent experience of these? Is it possible to pack them more and make them quieter? I have an FMF header already and it runs well with the STD airbox (+K&N filter) and STD carb. If I add the end pipe will it still run well or will I have to rejet? I'm a bit confused with rejetting, is it done to balance changes to the airbox and/or changes to the exhaust? I'd like to keep the airbox and carb standard if possible.

Hey guys, I couldnt stand it any longer. After listening to my DR and nearly every other DR I came across sound like the starter was a squealing pig I took one apart and found that the backside of the starter has a simple brass bushing in it that wears out. My bike had around 8k miles on it when the starter started squealing, I took it apart and greased the bushing and that worked for a while then it went back making that embarrassing sound that makes you hold your head in shame when you hit the E-buttonghead:. I couldnt take it any longer so off to the CAD program I went and came up with this little beauty.

Behold!! A new starter cap with a real sealed bearing in it for the armature shaft :





I have been running the prototype for some time now. Im pretty happy with how it turned out. A few quick mods and she going into production after the holiday.

I hope you guy's approve



This should make the starter brushes last longer and reduce the amp's needed to start the bike when your bushing is headed south.

Oh that's sweet Kevin!

just pick up one of the Busa pipes instead. They are MUCH cheaper and easier to find than the 40 GSXR muffler and Jesse's setup is that they only stick out maybe 1/2" more than the GSXR pipe. The beauty in this setup is you don't need to repack ever and the noise levels are closer to stock plus it looks stock.

Good luck with it!

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.
your mileage may vary
