After installing the Shad SH23s on my 'strom, I noticed there was about 3 1/2 inches of air on each side even with the shortest spacers. I also noticed that the bike was favoring the right side a bit more in turns and general handling. Having had 2 Rotopax on my last bike I decided I'd give it a shot. I ordered the 1 gallon water, but received the 2 gallon and decided to go for it. In summary, yes you can totally fit a 2 gallon rotopax in-between the Shad SH-23 and the bike without issue...on just the left side of course
Here were my supplies:
-- 40 bucks ---2 Gallon Water Rotopax (b/c water > than gas with a range of 250 miles...loving this bike)
-- 32 bucks ---Rotopax Standard mount (https://www.amazon.com/RotopaX-RX-PM.../dp/B002TTU96A
-- 10 bucks ---22 gauge welding steel plate 12x24 inch. I would have preferred 16 gauge, but this was all they had....we'll see how well it holds up
-- Free to me --- Clamp
-- Free -- Truck bed liner for the steel plate; you can use paint, vinyl scrap, or whatever you want to cover it....otherwise will rust.
Here were my tools:
--Drill and various bits
Two notes about the mount. You might be able to get away with the deluxe (additional handle), but due to the clearance I went with the standard....having had the deluxe before I'd opt for that space permitting. Also, I mounted it in this manner so that the Rotopax couldn't easily be stolen (locking case must come off first).
Method: I used the two bolts that mount the 3p bracket (1 that's into the frame) to hold the steel plate. I then snipped off any extra steel I didn't need, drilled holes for the two bolts, drilled a hole on the left for the clamp (to bring the sheet inward and prevent it from interfering with the chain guard), and then sprayed it with bedliner. See pics. No it's not super pretty, but the bracket is hidden anyway. Hope this helps all the DIYers! Comments welcome!
