Although the Shadow 750 bikes look good in their factory form the rear ride height often has the appearance of a dirt bike in that is very high off of the ground which makes lowering the rear end a must for a different ride quality as well as a more cosmetically pleasing stance. Depending on your desired look the front end of these motorcycles can be raised for a more raked chopper look or lowered for a custom bobber look. The information below is primarily focused on the VT750DC however it applies to the C2 spirit and all other models of 750 shadow as well.
Changing the rear sprocket is one of the easiest modifications showing the greatest noticeable change of any modification in the ride-ability of any chain driven VT750 motorcycle including the Shadow Spirit VT750DC, the Shadow Ace VT750CD/C3, and the newer VT750RS. Due to clearance issues the front sprocket must stay at 17 teeth and cannot be changed to a larger tooth sprocket for any added benefit on any modern VT750 motorcycle.
If you are just adding a stock replacement K&N filter or Pipes a stage 1 rejet is in order. If you modify the air intake with the Bean Box Mod you will need a stage 2 or 3 rejet including bigger #42 idle jets. An aftermarket intake or running pods on the carburetors will require a stage 3 rejet with new needles, large main jets, and #42 idle jets. Various manufacturers produce jet kits for the VT750DC motorcycle. Below are various part numbers from popular manufactures for the VT750 models.
Any time a change is made to the air intake/flow, fuel delivery, and or exhaust rejetting and carb tuning may be in order, usually these are changed with aftermarket or modified exhaust and intake. The exhuast may only require a simple fuel mixture screw adjustment on the carb, but an aftermarket intake or a modified stock intake requires more fuel to match the increased airflow which can only be corrected with a carb rejet.
Pulling the carbs apart for a rejet, cleaning, or rebuild is something that gets easier the more you do it, and may seem scary or difficult at first but is a necessary task for keeping your VT750 tuned properly. Below are a few pictures for reference to help you when working with the particular carburetor setup on your VT750.
Since around 2010 Honda has started using PGM-FI or Programed Fuel Injection Technology on all VT750 Shadow models including the C2, Aero, Phantom, and RS. are fuel injected bikes. The key to fuel injection is a more high tech system of sensors and monitoring of the engine and atmospheric conditions to provide proper fuel delivery to the combustion chamber. Instead of a carburetor PGM-FI uses a throttle body.
Here you will find a list of Air and Oil filter part numbers from various manufacturers for the Honda Shadow 750 motorcycles, primarily the VT750DC Spirit, including the filter numbers for individual Pod air filters that fit directly on the CV type carburetors for maximum performance.
Click here to see a listing of part numbers in order to relace the rear spoke wheel to a wider VTX spoke and to relace the front wheel to a 21" Honda rim. Because both rims come from a Honda the spoke counts are identical and can therefore be relaced to your stock VT750DC wheel hubs or any other Shadow 750 model spoke hub.
Making the change from stock tires to aftermarket tires makes all the difference in handling and even the look and feel of the bike. If you want a tire that looks skinnier than stock, or maybe wider you will find the size and a description of how it fits on both the stock and relaced rims here. At the bottom you will find a list of popular tire brands including available white wall options.
Some Honda parts are interchangeable due to similarities in the engineering and design of Honda motorcycles, the VTX headlight is one of them. All that is required is to simply replace the external casing and parts with VTX parts as the actual headlight is the same. This modification should apply to all Shadow VT750 motorcycles including but not limited to the: Spirit DC, Spirit C2, Ace, and Aero.
Years ago a company called Design Performance made compete performance conversion kits for the VT750 including ported and polished heads, high compression pistons, custom cams, roller rocker arm lifters, single carburetor, etc. With all of the above installed a VT750 was able to dyno 62HP at the rear wheel. Unfortunately Design Perfroamnce are not longer making these parts. The good news is that AFT Customs is now selling performance kits including aftermarket pistons and camshafts.
Here you will also find sources and part numbers for some of the parts DP used.
