Guy's I try my hardest to give you a great universal kit but you need to measure if 3 feet of 10 gauge battery cable is long enough for your bike. 99% of the bikes it is, check your bike to make sure.  Also, Super kit stator connection wire length is about 6" long,  Is that enough length for your hookup? Measure to be sure. Order more below if needed. Extra sheathing is included with 10 gauge cable add on. GSXR 600 and 750 with the R/R in the front behind the radiator need 1 extra foot of battery cable.  Jack

Add on battery wire length for all Mosfet kits....
Add on 12 gauge stator wire for Super kit builds only....Not complete kits!
    The Complete kit stator wire extension kit is down the page or the right side.

 Crimp & Go $123.95

The newest kit from Jack is the Strip, Crimp & Go. I am not an advocate of using your old harness to upgrade to a Mosfet regulator or the new SH775 but some people need this and who I am to say no. If your harness is on a new bike, or is in tip- top condition then this kit will work great for you. You just cut off your old stator and battery connectors and strip the wires and install the heat shrinkable connectors on your stock wiring making sure you have good solid crimps. There is no directions in the kit. You just strip, crimp and go.
This kit is fast and easy but you have to do it right. 8" wires on both.


This is a great little box is rated at over 500 HP in forward. The case is made from cast aluminum  Hi-performance gears and splines. Splines are 32 tooth TH400 Chevy so you can use a Chevy drive shaft yoke as a donor to build any type of connection flanges you may need. Pricing on this unit is $1195.00 plus shipping and handling

Mosfet R/R  adapter plate.......

I am now offering a universal mounting bracket for the ShindengenFH010AA, FH012AA,  FH020AA and SH775 regulators. The 2 way bracket can mount the  Mosfet up or down, left or right depending on your stock mounting holes. Comes with bracket and stainless mounting hardware. The bolts I enclose are metric #6 x 1.00 mm counter sunk. These fit most metric bikes. If these are not your size you will have to provide them. I also provide 1/4" threaded mounting bolts and washers for the Mosfet mounting. I personally build each one in my shop on my milling machine  in the USA. These are made with 1/4" aluminum flat bar. You can trim if needed for ultimate weight reduction. The 2 way is 1.5" x 4.00. slotted hole spacing can accept from 1.875"  to 3.40 center to center of bolt, spacing. If you need a different spacing I will custom build it for you for no charge within reason of course. Jack

and FH020AA Package deal,
SH775 also available



This is a T2500676 adapter harness for a direct plug and play for the Triumph Triple. It may fit other Triumphs but you'll have to check the part number and see. An avid Triumph owner told me it is the same connector found on a lot of other Triumphs. The picture of the ends should be a good indication of what it will fit.

Convert Your Stock CV carbs to Fuel Injection Throttle Bodies!! 
Yamaha Vmax kit shown Below...or  Build your own...
More info.

The easiest way to turn your 1985 thru 2007 first generation
V-max into a programmable, fuel injected street/strip machine
using your stock carbs. Just remove your slide covers and slides
and replace with your kit. You will need to purchase 
separately other fuel injection pieces necessary for a complete installation. More info..   You can convert most CV stock carbs to EFI throttle bodies. Older Honda Goldwings are a prime candidate for an EFI upgrade. So if your building a custom Goldwing or a Goldwing Rat Rod this will really finish it off and make it run great.
