Yr, Brand, Model

The motorcycle featured in this video is a 2002 Honda Shadow VT750. The video also covers 1998-2007 VT750's and 1995-2007 VT1100's years equally well. Note, this model has dual carbs, for single carb models, check out this How-To video.

Symptoms

This Shadow was non getting whatever fuel in club to burn down up, fifty-fifty with the choke on. The simply way it would run is by spraying some starting fluid inside the carb throat.

Diagnosis

Once the carburetors were apart, I found the airplane pilot jets and choke tubes completely plugged up. The choke tubes supply fuel from fuel bowl to enrichment/asphyxiate port for cold starts, while the pilot jets supply fuel at idle to ⅛ throttle positions. These are classic symptoms of letting fuel go stale and eventually leading to varnish build up.

The prepare

The just way to clean the carburetors is to completely disassemble them and requite them a thorough cleaning. There are no shortcuts (believe me I would dearest to know of whatsoever) or anything magical that you your into your tank to make this whole procedure easier. Once autonomously, yous tin dip the components in solvent, soda blast, and utilise carburetor cleaner in a droplets can.

Carb removal & install tips

Kickoff off, I did not follow my own advice and read the service manual prior to tackling this project. Apparently, it is easier to remove the carbs with the intake manifold (rubber carb holders) attached to the carbs. I eventually removed the RH side kick, and the carbs slid right out. When installing the carbs, make sure to spray some silicone spray on mating parts to help everything get together with less effort.

Purge and inspect the fuel organisation

The service manual covers how to bypass the fuel pump relay in detail. Why would you lot desire to do this? Well, there will be stale fuel in your fuel filter, pump, and lines. So empty out your tank, fill with fresh fuel, and purge the lines. This will guarantee fresh fuel into your freshly cleaned carbs, and should make firing it upwardly much easier. Make sure to inspect your tank for rust. If you find rust, see this post on how to clean and seal it. Finally, make sure your fuel filter is clean, supercede if necessary.

Airplane pilot jet & fuel screw setting

If I were to do this carb rebuild all over once again, I would have installed larger pilot jets, i-2 steps up from stock. The fuel screw during tuning ended up 3.5 turns out, which tells me the pilots are also small. Ideally, y'all want the fuel spiral out iii turns max. Larger pilots would brand throttle response much better. For more data on pilot jet sizing, meet this mail service, and sentry the video below.

Parts

Although the float needles were in "OK" condition, they started to evidence some signs of wear. There was a faint wear ring on the tip of the needle. Normally I reuse these parts, all the same given what a PITA it is to remove and install these carbs, I'm not going to hazard having to go through it all once more! The carb gaskets have seen ameliorate days, then I replaced them as well. Beneath is a rebuild kit that is fashion cheaper than going OEM.
