Bonneville Gas Tank

Surprisingly our customer didn't want to keep the old seagull gas tank so I picked this original slimline tank up on ebay for a reasonable price. As with all 40+ year old parts there is always some sort of a surprise under the paint!

The tank came with the knee pads and badges, badges will be back, pads won't

Surprise! The right hand side of the tank was pretty good.

The long crease was the worst of this side

No prizes for guessing the worst part here

This stud gun spot welds the studs to the tank allowing them to be pulled. I forgot to take a pick with the studs attached.

There's still a little left to do on the large dent but the shape is back.

Triumph Bonneville Project Update

I've been waiting on the hardtail to come in so in the meantime I stripped, and degreased the engine and transmission. Overall the engine was in good condition and although the pistons had seen better days th just may just get away with a hone.  The crank and jugs are now off to the machine shop and the cases, covers and heads will be soda blasted in house ready for the rebuild.

Bonnie engine is alive!

This is a short video clip of the engine running after having the electronic ignition fitted but before the rest of the upgrades. Sorry for the iPhone quality!

Triumph Bonneville Project

This is a new project in the shop that we started on Monday, here's how it looked when we took posession and how it looked after a days work. I also fired the engine up, then added electronic ignition and a battery eliminator. Once this was all tested I made up the wiring harness for the engine, front and rear lights and actual ignition will be finalised next week and added to the harness. The engine will be removed shortly for a complete rebuild.


She's a beauty!!


Here's where it starts

The old safety pin nut, one of my favourites! 

The original wiring

Less is definitely more! 

The carbs needed some attention! 

Battery eliminator, electronic ignition, new coils and new wiring 

All the wiring now runs through the frame

Ready for the hard tail 

CB350 Wiring

This past weekend at World of Wheels in Birmingham I had quite a few people ask where the wiring is in this bike. All the major componants are under the rear pod, from there the wiring harness and starter cable run in the 2 trays that i welded into the frame that you can see in this pic. At the back of the tank the harness splits either going to the headlight which feeds the controls or to the engine, the rear brake light switch and rear lights run through the frame and swing arm.
