So, one week, we were messin'
around (I mean carefully testing components.....) and decided to work
a bit on the venerable SV650.
So - we dynoed it, all stock exhaust, cams and carburetion and got about:
|60 True HP
(maybe 67 to 72 dynojet hp)
|Then we added a couple SV intake cams for the exhaust and our APK SV Carb kit with tank risers, with "not spectacular" improvements.||like 61 - 62|
|Next, we installed a set of
Megacycle cams that we were evaluating, still with stock exhaust and with
the same APK carb kit.
Ok - That's pretty good. power. Added about 5 with the Megacycle cams.
|65 True HP
(maybe 72 to 78 dynojet hp)
|Finally, we added a Leo Vinci
Exhausts on the SV don't normally add 10 HP - but the combination of a well designed exhaust cam + a well designed race exhaust will deliver better total power than either of the single items would, used individually.
|75.9 True HP
(maybe 84 to 79 dynojet hp)
|I've dynoed many
"race" SV's and very few match the power that this one put out - and
this isn't even a full racebike - it's a trackday bike......
When you use a properly designed
dynamometer, like the EC997 (not
a dealership level dynojet with
mythical hp numbers) you can isolate and manipulate many small engine
details that will ultimately produce far superior results - like this.
Parts and labor:
Under $2200 parts and labor?
Sure beats "high comp" "flat top pistons" and the wrong cams and complete topend disassembly for twice the money and less power......
So..... what would it be like if we did porting,
a bit of cylinder and head milling, cam degree dyno tuning, Factory
Pro billet velocity stacks, airbox mods? Maybe 80+ True hp (90 to 94
dynojet dyno hp) with still a stock bore and CV carbs??

|Ignition Advance Kit!!! - New!!!|
The most ignored power improvement on the internet.
Use this kit to advance the ignition timing 4 degrees for more power at part throttle and at full throttle.
Install the key with offset to the LEFT to advance the timing!
For easiest, quickest install - we suggest that you have access to an air or electric impact wrench - That makes it simple to remove the rotor bolt --
Kit includes special key AND Factory Pro's own heat treated, tool steel, plated rotor puller.

Carb Recal Kits: Config 30, Config 20, Config 10 and the Ti ProKit
Config 30 RaceKit
For applications where you
wish to REMOVE the airbox
se airflow - enough to add 3-4
hp to the top-end - without decreasing low-end and midrange. If you
are trying to tune on a dj dyno, we have reports that the topend power
does not show up under inertia loading.
Tech: Main Air Jet location
Airbox Plus Kit w/
race filter and carb recal kit
includes filter and carb kit and alloy tank risers
This is the original APK "AirBox Plus Kit" for the SV650
It's a special Factory Pro designed filter and will make
2-3 True HP over a stock jetted bike - IF properly tuned.
The APK kit contains the Factory pro designed filter and a properly designed Factory Pro Carb Recalibration kit. This carb kit is not just a regular carb kit with a different main jet. This kit also includes the elegant Factory Pro Tank Riser kit.
This kit does not require air filter or airbox modifications.
This IS a drop-in filter. CHECK WITH YOUR RACING ORGANIZATION FOR LEGALITY!
There's some additional carb mods that
could be done to make it a bit better when individually tuned on a good
dyno and I always said that I'd make a more expensive 2.0 kit if ANY
tuner ever noticed it. It was my "state of mc tuning" test. Kind of like
the black obelisk in the movie 2001.
Ti drop-in carb
Use with stock or aftermarket exhaust
Adds more low-end / midrange, if
the proper main jet is selected, more top-end power. Easy to install and
tune - no slide drilling.
Note: On the SV, no carb kit will "MAKE" horsepower. A Carburetor Recalibration Kit tm will allow you to install the combination of jets that will allow your bike / exhaust / intake system, together, to make as much power as the engine / exhaust / intake system CAN possibly make.
BMC Air Filters!
OPEN TOP Race Filter
Use the stock, unmodified airbox. Additional airflow is provided by a specially designed air inlet, developed by Factory Pro Tuning, for 1-2 more True HP than a stock air filter or the BMC stock replacement "S" filter
requires special APK Carb Recal Kit pn: CRB-S36-2.1-AFK.
Installing this special Factory Pro exclusive filter with a jet kit that was not designed for it will not result in optimum performance.
|BMC RACE filter
The "R" filter is a cleanable, long lasting, cost effective drop-in filter. Airflow is Minimal airflow changes mean that rejetting is not usually required. For more info: BMC Air filters
This filter has a STOCK size inlet
opening, making it legal for race organizations that require that.
It's a high quality, cleanable, long lasting replacement. Cotton gauze type filter is similar to other cleanable "1,000,000 mile" filters.
|BMC STREET filter
The "S" filter is a cleanable, long lasting,
cost effective drop-in filter. Minimal airflow changes. Not designed for
increased power and doesn't require rejetting.

Needle Jet Rebuild
Call 415 491-5920 to arrange - or email
It's true - the needle jets on the SV carbs wear out - just like the VL1500's and the cbr600's and 900's...... Happens with stock needles, stainless and titanium needles.....
We can rebuild them for $280 + shipping.
So - If your SV has started racking up the miles and seems to be getting rich and sloppy at low rpm (especially), and you can't fix by lowering the fuel level anymore - it's time to rebuild them -
Shifting issues with SV650's can be seemingly random.
It is the centering on the shift shaft that aggravates either upshifting or downshifting,
This is good.
The pins are centered between fingers when the shift shaft is at rest.
< This is not so good.
The pins are not centered between fingers when the shift shaft is at rest.
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!
Adjustable Center Shift Stud
SV650, SV1000, DL1000,
If the shift shaft fingers aren't centered on the shift shaft, Factory Pro has the fix.
It's a special
offset "centering" stud, adjustable by almost 1mm.
The difference in the above example was only .31mm/.024".
Install the stud with
enough threads exposed for the locknut.
This fits all the SV650's, (and probably the 1000's)
This Carb Recal Kit developed on the same EC997a Eddy Current dyno that developed the K59-1.7-RK ZX-6R RaceKit (Muzzy and Kinko's choice), the Y73-1.7-RK YZF750 (Vance and Hines choice), S37-1.7-RK GSX-R750, Suzuki of France and most of America's privateer racers choice)...

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.
