Bobbing a -67 Bonneville

[Johansson]

The Amal 930 carb on the bike is quite worn so I have decided to buy a new one instead of having it resleaved, they are so cheap that repairing it for almost the same amount of money doesen´t make any sense to me.

I will take a bit of a break from the bobber build and focus on some other stuff like the landspeed bike and some customer jobs, not much left to do on the Triumph but rewiring it and painting the rear end so I have much time to do it before next summer.

lot of great progress since the last time I looked, any idea what you're doing for color choices yet? looking good

Thanks! I´ll keep it just as it is, scratches and all. Getting a fresh paint job on it would completely ruin the look I am after.

Tonight I started to wire everything up, don´t mind the green and red wires because everything will be covered with black shrink hose.

Any progress?

I am also in the process of casting a gearbox casing for a friends bike build, a Suzuki 700cc two stroke snowmobile engine with a Honda CBR1000RR gearbox in a home made tube chassis. Very interesting project and if it turns out well there is little that cannot be done by lost foam casting.



Cheers!

where can i see a built thread of that snow engined beast ?

Hi guys, sorry I missed the latest replies. All focus has been on other workshop projects lately but I promise myself to up the pace on the bobber build soon. It has to be running when the roads are ice free.

Skunkworks: Sure, check this thread out. Not much progress yet but the frame jig is built and an engine is sourced, I haven´t managed to produce a flawless gearbox housing yet but later in the spring when outside temps are a bit above freezing I will give it another try.

A new Amal 930 carb is bought to replace the old worn out one that came with the bike, a overhaul manual and a engine rebuild DVD was bought as well to save me some trouble when the engine needs some love.

I compared different front fork heights today to find the right stance, the first pic is with the original fork height and the second one has the forks compressed until the lower frame tubes are parallel to the ground.





You can never guess which one I like the most...

Cheers!

The wiring and oil lines are done and the rear frame is painted, not much left to do now before it can be started for the first time since I started building the bike.





Cheers!

Tjooo!!

[Johansson]

Tjo on yourself!

Last night I painted the oil tank and filter, I am a bit concerned though that the newly painted parts will look "too new" compared to the rest of the bike so I might dull them a bit with Scotchbrite...



Cheers!

looks great man! love the oil tank.

the wrap will loosen and unravel due to the wind catching the leading edge of it, that's why it should be wrapped from the end of the pipe forward. i run wrap on one of my bikes and it lasted about a year so it's time to re-wrap it. the more stainless clamps along the pipe, the better.

i have to run the wrap to keep from melting my pants. they all have "bite" marks on the pant leg.

Coming together nicely, keep it up...

Thanks! I know that there are different opinions about the oil tank style but I like it and that all that matters.

After posting the wrapped headers in a Swedish motorcycle forum a guy told me what you just said, that the wrapping was done in the wrong direction and that it wouldn´t last.

I think I´ll unwrap it and do it right before I start the bike the first time, it didn´t cost very much but I don´t want it to come loose at speed and end up in my rear wheel...

Yup, and it is only january! This winter will feel very very long...

Or you can spinn around in the snow

I will probably take it for a ride some sunny winter day, no cold starts though since pumping -15°C straight 40 oil will be like sucking a brick through a straw...

[HD48FL]

Congrats!

[S.G]

Let it go hot inside and then out, had a Svalan with spiketires that i used to race around with(but it did go on straight 50) either way take it safe and run it on a sunny winter day, post the video

[Johansson]

Will do!

The fork legs are about to get a pair of spacers made, I need to lower them 7-8cm to get the right stance.



I´ve also made a brass fitting for the throttle wire in the throttle grip and some other minor stuff, I figure if I keep the pace up and finish the bike in a month or so I can focus on the gas turbine bike build 100% this spring/summer. That is badly needed if I am to have it ready for Speed Weekend 2014.



Cheers!

With a few subtle differences, this thing is damn near my exact vision. I am inspired to the max by your build and non shiny expensive paint. That oil tank is the t!t$, I have held off on getting one for mine because I am tired of the sideways below seat mount option everywhere. Saw a vintage oil bag that was cutout and doubled a while back pretty impressive too. Thank you for sharing your build, Chad P.

[Johansson]

I am flattered to hear that you are inspired by my build, I am hoping to take some better photos of it outside when the bike is put together again.
