20 Most Recent 2002 Triumph Triumph Bonneville Questions & Answers

Hey J.. make sure your battery has the necessary CCA..(Cold Cranking Amps).. this is the true measure of a battery.. and you have replaced the starter solenoid..?.. hhhmm...?? ... Still sounds more like the battery is low on CCA.. ....bypassing/jumping the solenoid allows the engine to start with having/needing the amperage necessary to make the solenoid contacts activate... Amperage is what "pushes" the voltage.. without the required amperage (CCA).. voltage, when relating to starting your bike is "just voltage".. it will run a light, but NOT start a motorcycle...Good luck.

Possible vacuum problem in fuel tank? Try riding with fuel cap slightly loose if possible then see if the problem goes away. Maybe the venting for the fuel tank is blocked.

If it has been standing for a long time the fuel could have evaporated from the carb. Evaporated fuel leaves behind a powdery residue that could clog the jets in the carb which would make for hard starting and poor performance. If started and this happens, run some carb cleaner through the engine. Also, shaft seals tend to harden, so be prepared for some oil seepage. If luck is on your side then you wont have a single problem.

Just hook one of them up and you'll know. all it can do is flash. You have a 50/50 chance of being right the first try.

is it electronic ignition? - if so, the ignition heat sink unit may be gone...should be s omehwere on the underside of the tank shroud. do you have a manual for it?

Sound like it could be the stater or pulse coil

Check the fuses and the connections on the wiring harness. Trace how far the power goes. Where it stops is the problem.

this is going to sound bad but some where you have lost power to the coils pull every thing back apart and the first thing i would do is look at the tach you changed no singal i bet when you are cranking the mtr over, see if the tach show rpm while cranking . if it dose not install your oem tach good luck kdc744

try here mate you may find what your after

hope this helps

First of all, why would you? Where are the keys? Are you the owner? What make and model?

Yes they are plugged if they have any ethanol fuel in the fuel system and the fuel system had no stabilizer added. The fuel system will need cleaning

1971, March 1971 to be exact

Under the seat

It could be worn rings ( especially if it is an older t120 60's-70's ) that is allowing compression into the crankcase and blowing the oil out the breather.

Try checking the ground line from battery to engine if that is OK The starter may be faulty
