    I went with 3.5 inch rear wheel. That was what woody recommend from a bike weight stand point. You can run a 140 or 130 on it.

    John - that's good to know a 3.5" rim works good on the Sportster. I currently have a 2.75" Sun rim but Im considering changing and having the option of an Excel 3.5" for more street biased and 2.5" for more dirt biased. Both will accept a 140/80 tire.

    How did the 3.5" do in the dirt? I know you did plenty of off-road on your trips!

    It did very well for me. The rim took more abuse than a typical dirt width rim. I play in the rocks a lot and have a few nicks in the excel rim. Nothing bad but they are there. I am looking at a 17" front wheel for the canyon carving and hope to keep the same rear, at least for the time being. So that will put me with a 120 front and a 140 rear. Presently I have been using a 130 rear tire.

    Those Harleys do seem to hook up and go on a good Mile track,I can see how a Sportster engine would do the same on a fireroad!

    Nice build going on,I used to think my DR was big for dirt riding,maybe not so much now.

    Hey,

    I purchased a scratch and damaged peanut fuel tank so I could powder coat it and use it as a temp until I build a bigger fuel tank, but honestly I started to like my tank.. So I am seriously considering to steal your idea and duplicate you with fuel cell on rear and add top case on top of it. So I am curious, how did you like putting gas in from rear? :lol3 How did bike handle with the weight in back? I assume it is almost like carrying a young teenager?

    Who made your? You? and what was it made from? Aluminum? I am on the fence whether to make it a fuel cell and top case as one or a fuel cell with quick latch to secure the top case so I can carry-on top case into motel/hostel. I'll probably go with wolfman expedition saddlebag on side after I had difficult weaving the traffic with aluminum cases on BMW 1200GS in Colombia last month.

    Thanks for the reply! If I may ask, what's the measurement of your tank and how much gallon is in it? I was thinking of making mine 8" wide and 16" length with about 8" tall.. should get 4-5 gallons out of it?

    Thanks!

    It is a 4.5 gallon tank. It's made just wide enough to fit between the fender struts. The bottom of the tank is the inner fender. With a sump built to the front of the tank and then run to a fuel T with a shut off valve. I had a total of 7.8 gallons and got 50mpg. It's a great bike.

    nice to see you are building another ride after a wreck.I hope you did'nt get too banged up.I built a Sportster and modified the gas tank by cutting it in half lengthwise then added about 4 inches or so and relocated the filler cap.It now holds 20 liters and still looks like a Sporty tank from the side,just a little wider looking at the top of the tank.You might be able to locate some pictures if you do a search for "Another Sportser conversion" if you are interested.Keep up the nice work,I am enjoying the pictures.

    Can you tell me how you got the hdb handguards to work with 1 inch bars? Also do you just have a screaming eagle air filter with stage one jet kit or what carb/airbox mods? Thanks!

    It's a NRHS breather kit. Stock carb, but a sport has different jets than a normal sportster, probably cause of the dual plug heads.

    The handle bars are fat bars which are 1 1/8 and taper down to 7/8. They work with the dirt bike clamps I had. Now this time around I am using the 1" bar but have not mounted the hand guards yet. Most guards use a swedge which may work with 1". I haven't decide whether I'll do that or weld a threaded insert.

    Thanks John, so do you also have a SE air cleaner/box? With stock jets? I also have a 1200S and am looking to add a little more power but want to maintain 50 mpgs as well. I am also looking for cold weather hand protection but the powderpros I was looking at are 150, the same price as the HDBs which also have more function but yeah, they arent a direct fit. Will be watching to see how you get them to work. Liking the direction of your 2nd edition sporty!

    I have NRHS air cleaner base with the steaming eagle cover. The NRHS kit you can get with a 2" or a 3" K&N filter. I'm still running stock jets and it does good with them. I'd say it just a touch on the lean side, but it still runs good at 10,000 ft which is nice when the single I ride with are running out of lung capacity.

    Thanks for the props on the 2nd build. I think this will be a lot cleaner looking and still be functional. I need to either machine a custom top clamp for the HDB or run some off the shelf guards for fat bars and trim them just a little. Haven't figured out what will work best with the stock gauges. I have both laying on the shelf used so we'll see.


    I'm hoping Jimmy's plastic tank is done soon enough to use on this. I really like the look and extra capacity. If not I may build another rear cell that fits under the gs rack. The bmw guys love me :lol3

    Got some loose ends tied up and working out some details. Tightened up all the bolts I could touch and took it for a little spin
