Last saturday night I decided I needed some workshop time with a couple of beers after the family had gone to bed, so I headed out to the shed and continued working on the fuel tank. cheers



A welder needs quality music! Smiley



The tank is cooling off after welding, the Argon bottle is almost empty so I need to get it filled before the next workshop pass.



The tank lid in place and lids placed on the fuel return and breather connections.



One of the rear tank mounts in place.



The other of the two rear mounts, sturdy enough I believe.



While waiting for the tank to cool down I made the last three braided fuel hoses for the bike.



Here the tank is in place, it was almost 3 in the morning so making the front mounts had to wait for some other day.



A snake nest of hoses everywhere on the bike, I will have to figure out some fancy aluminum clamps later to arramge them a bit.



Cheers!

Thanks!  smiley

I guess so, I try hard to keep in mind that every single part on the bike must survive hours of bouncing around at high speed down bumpy tracks. It wouldn´t be very fun to drop and run over the oil tank at >200mph...... shocked

I have a question about the foot pegs, do they need to be foldable or can they be directly welded to the chassis?

Last night I finally had time to get some stuff done on the bike again, I´ve been away at work for a week so the fingers were itching bad from being away from the tig welder and mill for so long. Smiley

I got a new gas lens kit for the tig torch which I intended to try out while finishing off the fuel tank mounts.



Two aluminum brackets were made to fit as the front mounts on the tank.



The patient is laying down and ready for surgery! Smiley



The gas lens was an improvement, not bad since it only cost me a couple of bucks on Ebay.



Here the mounts are in place and the tank is cooling down after welding.



While waiting for the tank to cool down I made a pair of steel brackets for the frame.



Fixing everything for welding, finally I will get rid of the last strap! Smiley



The tank in place, the only things left to do on the tanks are to weld some brackets to the side of the tanks that the oil suction hose will be strapped to and make a fitting on top of the oil tank for the gearbox oil drain.



Cheers!

Great work Anders!  cheers I love all the lines. Makes it look like a rocket ship!

As far as your musical taste goes, I too rely on a little Sepultura to keep the build progressing!

Thanks! I would´t want to sum up just how much cash that is invested in those Dodge AN couplings though, one here and a couple there and suddenly the wallet is empty... grin

Workshop music for me is very much mood based, metal one day and Toy Dolls (brittish punk band) the next. Add some bluegrass and blues to the mix and you have one happy Anders. smiley

I´ll bump the previous question about the foot pegs, does anyone know if they have to be foldable or not?

I have fixed pegs on my Modified bike that I run at the BUB trials on the salt.  You may want to use temporary pegs with clamps until you KNOW when they should be after a test run.........or three undecided

We switched to folding pegs for one of the associations regulations think it may be FIM , but had been fine with solid pegs for several yrs before that

Thanks for the answers, a good idea about the movable pegs so I can find the right riding position. Not easy to figure out by dry riding it in the workshop.

Sometimes a rigid peg is the easiest mount for a removeable sidestand in the staging lanes.  You will spend more time pushing slowly forward in the lanes, than you will riding.

Also, I have built bikes with even footpegs and others with goofy-foot pegs.  Goofy-foot can be easier to ride when the bike is super low.

Thank you for this build diary, I am really enjoying it.

Thanks Jim, I´ll keep that in mind for when I build the pegs.

I made some progress today by the way, first I made some brackets for the battery mount and welded them in place.



I will think a bit more about the battery box before I do something stupid and can´t get the gearbox out of the frame any more, most likely a removable box properly heat shielded so the battery won´t blow up from the heat generated by the exhaust.



Next up was to fit the wind screen so I can take measurements for the dashboard, I drilled a row of 2.5mm holes around the lower edge on the screen and matching 4mm holes in the fairing. The idea was to fit a zip tie through the windscreen hole, down through the 4mm hole in the fairing, around the aluminum rod you can see in the picture below and up again through the same 4mm hole.



This way I can tighten the zip tie hard without cracking the glass fiber fairing, some silicone around the gap between the windscreen and fairing later will do the trick.



Before I called it an evening I started making the chain adjusters, but I´ll get back to them in the next post after I have made some more progress.



Cheers!

Every one to his own taste but when I'm working in the shop I prefer some Tal Farlow on the stereo system.
