Hi Marc,
The stacks arrived at 9:30 this morning and were installed by 10:30. They looked and felt very well made. I don't know if you've had them made my a third party or make them in house but whoever did it made a great job.
I wasn't quite prepared for the difference they made to the bike. My bike is totally standard apart from a K&N filter and acceleration is much improved, a great product.
 Thanks for a great product that actually works.

Feedback on 35/70 stacks


Feb 2018

Hi Marc,

Finally had the chance to fit and ride with the velocity stacks.

Worth the wait! Sound and look fantastic. Great quality finish.

Looking forward to the shift star and shift spring.


2007 December 07

Hi Marc,

I installed the FP 35/70 velocity stacks on my 03 SV650S in about 40 minutes. What a difference! I am running a modified stock pipe, timing retard eliminator and a SV1000 snorkel. Other than that the powertrain is stock and the ECU has not been changed. The stacks made a noticeable difference, particularly in the midrange. All I need to do now is find a Factory Pro tuning center close to me.

Feedback 35/35 stacks

June 22, 2009

Hey Marc,

This is Jordan and I just wanted to let you know that the velocity stacks I ordered from you guys work perfectly!
I went for the 35/35 kit since the low end of an SV is already great and the top end is so much better!
With my Scorpion shorty slip-on my top speed increase 3Mph and that was on level ground, before it took a downhill to get my top speed!

When a product produces power you can feel you know it was worth the investment!

Sometimes it's hard to tell if a company is legitimate with their dyno charts but all I have to say is your company is outstanding and completely trustworthy. Fast shipping is also a plus.

Thanks for such a great product.

Regarding modified engines with different cams, porting or displacement.
As normal, you can't predict what length stack will work the best on a modified engine.... I can guess by looking at a loaded hp dyno test, but, don't send in dynojet hp runs, as inertia loading distorts the shape of the power curve, eliminating any usefulness for tuning.


SV650 Hi RPM / max topend
Superflare Velocity Stacks
(use with stock air filter, BMC, K&N or similar filter)

Work well with bored throttle bodies and cam swaps.

Another great power product from the only mc focused company in the world that produces a large variety of tuning products AND supports good product development by producing the most sensitive of chassis dynamometers, the EC997 Low Inertia Dyne Systems - the same EC997 dyno system that F-USA and ASRA use to police power levels in HP race classes.

In just 45 minutes and regular hand tools, these new Factory Pro designed Superflare billet stacks will provide 2-4 True HP, generally even without retuning.
That's what we got when we did R&D on a stock engined SV650 that had a common competition exhaust system installed.
We'd expect about the same results with an SV with a street exhaust system or even the stock exhaust system.

As I recall -

After a race's worth of running over 100 AMA and WERA bikes, we gained from 2% to 3% power,

The least I saw was 1% (JR's super loose built engine) and the most I ever saw was 4% (on a super tight street  built engine).

The other 98 bikes picked up 2% to 3% power - with most 2% and  2.5%

Lasts 2 and up to 3 oil changes (tapering off in effect).

Evo Shift STAR kit, Adjustable Centering Stud, shift kit sv650


SHFT-EVO-S59-KT   $199.95
(S36 STAR, NO Arm, spring kit)


1. Choose your shipping method


It's everything that I ever wanted to do to a shift mechanism -
Slightly stronger detent spring - a new MicroBearing detent arm and the final piece... A completely redesigned, empirically refined, multi angled, variable radii, repeaked and valleyed:

Much better neutral finding and shift precision.

Much better neutral finding and shift precision.

EVO Shift STAR Kit
This part will totally change the feel of the bike. The shifting effort is about the same - but the speed at which the gears actually engage is dramatically improved - Quicker, easier, shifting - A "twitch" on the lever and the throttle and you are in the next gear! Perfect for track use and road riding for effortless downshifts into a corner and just a "tap" to upshift without any more than a "twitch" off the throttle - That's not even mentioning that missed shifts virtually disappear.
It is a significant improvement over the "05" and later shift star.
In town? Low rpm cruise in second - shift to third? So quick and smooth that it will surprise and amaze - NO more clunky, lazy shifting in town - As I said - it's totally different and improved -
Proven concept - Virtually all the Factory Pro Support riders in the AMA and WERA multi- Champions Vesrah Racing tested and proved the EVO-7 Stars in 2003.
Stock shift performance that everybody used to take as a "given" will be regarded as "slow and lazy" after riding a bike with this kit -
Kit includes a new detent arm with a low friction microbearing roller, a performance shift spring and the NEW Factory Pro EVO Detent Star.
Make shifting MUCH quicker and virtually eliminate missed shifts.
It is a significant improvement over the "05" and later shift star.



2012 DL650 L2

Hey, I just had the shift star installed at Factory Pro. I let Marc talk me into it after he heard me lamenting about false neutrals and how "ratchity" I thought the shifter was on my Glee. Yes, I keep the linkage clean and lubed but I've never been happy with it. Well, I must tell you, the Factory Pro shift star mod works. I wear work boots during the week and touring boots on the weekend so I was always adjusting my shift lever. Now I leave it in the "touring" position and all is good. The shifting is now smooth and concise no matter which position the shift lever is in. Tick, tick, tick go the shifts.
Thanx Marc

SV650 07 (upgrade from "05+ stock shift star)

I installed the factory pro detent star kit on my 07. Make the shifts much nicer. The rowels on the aftermarket star are much larger in diameter and the piece is beefy. Great way to emulate a much more expensive transmission setup like what you'll find on a stock race replica.

Pro Transmission Detent Arm Kit

The original shift improvement kit -

Ever miss a shift??
Includes Factory Pro Microbearing Detent Arm, heavy duty detent spring and gasket. Makes shifting more positive at the expense of slightly stiffer shift lever action. The stronger detent spring rotates the shift drum quicker, so the gears are more likely to engage under quick shift conditions. The Microbearing removes friction for the quickest possible shifting with the least amount of effort.

Includes: Factory Pro Microbearing Detent Arm, Factory Pro Detent Spring and a clutch cover gasket.

I got the new star and stud.  Put it in and adjusted it all up.  Now everything works great, great feel just like I would expect.  I might just have to get one for my new SV1000 superbike race project!

-Michael Schmidt

If the shift shaft fingers aren't centered on the shift shaft, Factory Pro has the fix.
(see bottom of page for tech)

It's a special adjustable offset "centering" stud, adjustable by almost 1mm. For visual example, the difference in the below example was only .31mm/.024"!
More mature (lol!) experienced mechanics will recall when almost all transmissions were equipped with a part like this. That allowed the engine builder to set the shift shaft to exactly in the center for the best possible shift performance. That part, along with shimming and clearancing gear spacing, is what "blueprinting" a transmission is all about.

Install the stud with enough threads exposed for the locknut.
Turn stud till shift shaft "fingers" are centered on detent STAR pins.
Tighten down the locknut.
Recheck indexing.

CHECK!!! For things that may interfere with the taller stud!!

This fits all the SV650's, (and probably the 1000's) at least up to 06 and you may find other applications that it could be used in.

Sigh..... In the "old days", a good mechanic would center everything, grind special shims, clearance and reshim gears on the shafts, move gears closer to get quicker gear engagement and reprofile and polish shift star pins and ramps for the slickest working trans.......
Luckily, it's not 100% mandatory to do all that anymore, but - when it's all done - you'll get the slickest shifting transmission, ever.
I still do all that as a project, though - I kind alike doing it in the evenings and weekends.

Requires pulling the clutch assembly to install (no case splitting required), so it's perfect to install when installing a Shift STAR.

November, 2006

I notice you have an advancer for the '03-'06 SV650. Will it fit the Suzuki DL650 VStrom? From what I understand the engine is very similar. I put one of your advancers on an '01 SV650 and loved the results. If the advancer works on the VStrom, can I expect similar results?
Thanks, Kurt Larson

Yes - it will fit the DL650, also - Marc

This chart shows the results that we got on my favorite C-130 pilot, Bill Winkershan's SV650 after adding adding the Factory Pro RTR-SUZ-36-04 Ignition Advance Kit.

We did some minor trimming of the fuel with the TEKA SFI, but most of the improvement was just the advancer kit.

You can look at the lower red and blue lines that indicate CO% and that it's virtually the same.

CO% is the advanced mixture method, far above "AFR" tuning.

The testing was done using 91 octane pump premium fuel (2007 version) - so Pro V and MR9 should work similarly.

The Ignition Advance kit CAN be installed backwards, if desired, to retard the ignition timing 4 degrees.

Alloy SV650 Tank Risers

RA-TNKRSR-S3617   $29.95

1. Choose your shipping method

2 risers and stainless steel allen screws
International buyer will be billed an additional $18

Yes! These are the ORIGINAL Factory Pro Tank Risers

When the first SV's came out, we discovered that the fuel tank was too close to the air inlet for the airbox and it blocked some valuable air flow - hurting peak power (and the 650 needs all it can get!!)

So - In our old premium SV650 carb kits, we provided 17mm risers (16mm wasn't enough and 19mm was awkwardly high and did little more than 17mm) -

So - the "magic" size of 17mm was born.
The carbureted SV650 needs them, too!!

+1 True HP in 5 minutes!!!
 (Could be nothing to 3 on a dynojet dyno, but most of us know that's just typical ludicrous dj dyno error)

OK - You can get a longer screws and stack up "fender" washers or you can get these cool alloy machined tank risers and stainless steel allen screws and be COOL!!!


Congratulations!  Mike Solis - Race winner - SV650!

NOTE! Shifting Tech!

Some shifting issues with SV650's are random - bike to bike,

We finally got an 05 that has a problem - It is the centering on the shift shaft that aggravates either upshifting or downshifting, but not both. The Factory Pro STAR will make shifting quicker and easier, and the Centering Stud will make it perfect -


< This is good spacing.

See - the detent star pins are centered between 2 fingers when the shift shaft is at rest.

We used a folded business card around the stock centering stud to rough figure the offset required -

bad spacing

bad spacing
< This is not so good.

The pins are not centered between fingers when the shift shaft is at rest. The LEFT finger is much closer to the shift star "pin".

If they don't drop down fully, beyond the "pins", that prevents the "fingers" from dropping down and getting ready for the next shift.

If you've got issues - check!

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
