I recently purchased my 2001 Bonneville, privately, with a genuine 8,700 miles on the clock. Its a two owner bike with a comprehensive service history. Its my third Hinckley Bonnie and has standard carbs fitted. Its in standard factory spec except for TORs and a Triumph alarm fitted. It hadn't been used for a while before I bought it but appeared to run well. It starts instantly, cold or hot, ticks over well but has an annoying stutter between closed throttle and opening up again.
The exhaust gas recirculation kit has been removed and plugged.
The carbs are clean inside and have standard jets. Fuel mixture screws set at 2 and three quarter turns out. It has needles with adjustable settings with the circlips on the third notch down. It has the factory airbox/air filter. The diaphrams appear to be in good condition and the slides move freely. The spark plugs are new and appear to be burning the right colour. However, when checking the wiring, I noticed that the Throttle position Sensor was not connected to the main loom or anywhere else and that there didn't appear to be anywhere to connect it to !
Stupid question time, where on the loom should the TPS plug connect to ? Is it hidden from view ?
Could the person who fitted the Triumph alarm have used the TPS Sensor wiring as a power source ?
Once the stutter has cleared, it pulls very well, however, when I returned home last night from a 50 + mile run, it had been stuttering more than usual and backfiring on tickover, eventually cutting out at a junction.
The lights are bright and it appears to be charging ok.
I know its difficult to diagnose a problem when the bike isn't in front of you but any helpful advice would be very welcome.
Thanks, Mac.
