1967/1969 Bonnie Rebuild Desert Sled Project - Any Advice

So - Looks like I will have the opportunity for some more learning. I will probably need your help when I finally get to this point. Thanks for the advice!

 

Exhaust pipe hangers - so I took a couple of EMGO exhaust pipe hangers and modified them a bit to provide support to my upswept pipes. They seem pretty secure now. I think if I had a bit more equipment I could make something a bit more elegant so perhaps in the future I may try something different but this will do for now.

I am getting close to needing to install oil and fuel lines. I’d appreciate any advice about the sizes and type of lines I should use as well as the kind of fasteners/clips that work well. Thanks for any advice!

 

Yes, after a lot of going back and forth a bit I ordered some Amal Premier 930 Aluminum concentrics - when I finally found them.

 

Thanks for the advice on fuel/oil lines, as well as the clips. I see how one could plug the hose when installing. Hopefully this is not something you did in the past? I will be careful. Someone else mentioned putting the ends in boiling water to help install the lines.

 

I finally got my carburetors and hope to install them shortly. These are the matched, left and right 930 concentric premier alloy body carbs. I am wondering if I should change the jetting of these before I install them and appreciate any advice on this. The box indicates the Main is 200, N/Jet 106, Pilot RJ17, Valve 3. I don’t know what all these numbers mean but sure some of you do. As my bike has the 750 kit on it I am wondering if I need to change out the jets? Thanks for your advice on this.

Also, I ordered a Triumph Inlet Carburetor Mount Set 14-1301 Stiff-Nut Cupped Washer 1970 & On - New. So for some reason I thought I would need these to install my carbs. They seem to be a sort of rubber mount. But from my parts book it looks like the carbs on my bike were installed with just a locking nut. Any advice on using these other stiff-nut cupped washers?

Lastly, I’m working on putting my oil lines together. I installed a choppahead oil tank. I’ve got this alloy rocker oil feed pipe that I am planning to use. So it seems seems like the oil, whether in my feed pipe or the standard feed pipe, somehow flows through the pipes and fills up the space in between the chrome dome nuts and everything else with enough pressure to finally make it into the end of the rocker spindles. Is that how it works? It seems to me with the dome nuts tightened down the oil would no make it to the end of the rocker shafts. Am I missing something here?

Thanks for any assistance!

 

Thanks for the advice! I'm using Champion N3C's.

 

Also, I see that there are phenolic insulating spacers of various widths to use along with the gasket when installing the carbs. Do you know if this part is necessary - or is it recommended? Thanks again.

 

On the Amals and fastening them, I saw one of Raber's old videos explaining the various set ups. So I think I've got a good understanding of the various options. I think on my bike originally it was just metal to metal, and the various fixes came later (maybe). I think I am going to try to get the thicker O rings and other fasteners to make the carbs sort of rubber mounted. Seems like a good fix. The Amals come with the thin O ring so I'll need to get the thicker one. This keeps the carb separated from the manifold so it allows for cooler running, which was the reason for the phenolic spacers in the other version of fastening the carbs.

 

Thanks Iron. Helps to see this great description!

 

I have a question regarding the setup of the carburetor manifold. How does one determine how far to screw in the manifold? Do you screw it in as far as it will go then set the lock nut - or do you determine to set it at a certain distance and then lock it with the nut. I appreciate any advice.

 

More advice needed for my carburetor install. So I have new carb manifolds and thanks to a forum member they are now painted with metallic rust-o-leum. I also just received the mounting nuts for the carbs and notice that the studs on the manifolds are too long for the nuts to tighten the carburetors - see photos. So now I am wondering how to manage this. I see there are phenolic spacers available in various thicknesses, like 30mm. I suppose using one of these on each side would allow the nuts to engage the carbs. Any advice on this? Also, if one uses the phenolic spacers how does one use, or not use, gaskets? The carbs have a very thing O-ring. So If I am to use phenolic spacers to get the proper distance for the nuts to engage, where would I need to use gaskets? Thanks for any help.
