The TPS or throttle position sensor is a simple device . Google " testing a potentiometer " . It will help you to perform this operation with confidence. You will need a GOOD DVOM , test leads that will probe connectors and an understanding of how to use it . p.s. this will be easier than you can imagine !

Do you know how to test the one that is on the bike ?

Docc, there are o-rings under the rocker arm assys. that need replacing. Very easy to do. You have a parts catalogue that shows them ?

Remove the spark plugs..With the bike on the rear stand , shift the bike to 6 th gear and rotate the rear wheel . It should rotate with some effort because there is no compression . BTW you need to test the charging system , replace the battery if it needs it , get a good battery charger and rehearse how to jump start the bike. There are smaller jumper cables that are available for 4wheeler/motorcycle applications you can purchase .

In your picture the seal is next to the fork tube .

Are you using a digital meter to see what you are using for reference ? The battery should show at least 12.5 v with the ign. switch off. If it is properly charging it will show between 13.0 v & 14.5 v around 1500 rpm. If your battery is hot to the touch it probably has problems . Is the battery still under warranty and or can you install another to make it home ?

I don't think it's possible, to fully understand Luigi's wiring. You all need to look at a German automobile wiring diagram for a couple of hours............................

How do you work the injector manually ? What brand spark plug are you buying ?

If the tank has a black foam pad around the fuel cap it has an external fuel pump/filter setup. If the tank is smooth it has an internal pump module .

Which cylinder drops out ?

I don't think it works that way......

You are not going to hurt anything by replacing the filter. Get a GOOD brand and replace it. Record the date & mileage .Keep up with ALL your services for you or the next owner .

I found them . Do you need them ?

I think I have some I bought off eBay... If you still need them post and I will try to find them .

You say " no fuel is getting into the cylinder" ....how did you come to that conclusion ? Is there spark at the spark plug wire...is the fuel injector firing ....etc. ? If it is running on one cylinder , the fuel pressure is good .

I think it has an aluminum washer that seals it , so just transfer it to the new sender .

Well...can you give us some dimensions , head configuration , etc... ?

Whai is the hex size and nut shaft size ? If it is 30mm hex and 19mm shaft size I have one . PM me your address .

You mean the GB was your first two wheel experience ? What in the world inspired you to get it ? Those things never sold well and now they are sacred ?

Whew....no good advice here . i am running Pirelli Diablo on mine.. Be sure to fill w/nitrogen .

The Duc can become an off-road bike pretty quickly.......

Duh.... AC as Alternating Current... LEDs will last a lifetime and be brighter too.

It is supposed to be...I bought two..put them in the back of the bike and haven't broken one yet.

Yes, they can leak ...start the bike and let it idle a while. shut it off and get the baby powder out and start applying it until you find the wet spot(s) .
