I would like to publicly thank Motocycho for successfully mig welding my tank back to a functional state.
For those of you who missed the thread I posted a couple of days ago, my bike mysteriously got a hole in the underside of the tank and Mike was kind enough to offer an attempt to fix it, and he came through tonight like a champ.
At the beginning of last month the bike was transported up from Fullerton, CA to Provo, UT. As it was driven through the scorching heat of Death Valley and Las Vegas in an open trailer at mid-day, Mike figured that the heat, combined with the elevation change, was probably way too much for "the lil' 9er that could". As a result, the tank morphed in several places, (CA charcoal canister didn't allow for the pressure to be released???) but one particular spot on the underside of the tank expanded so much it caused a crease in the metal further down the tank which buckled and later opened a nice little gash that proceeded to dump gas all over the bike this past week.
Since I had brought only the tank and not my whole bike out to his place he took his
919's gas tank completely off his bike because we needed to make sure that after we tapped the underside of my morphed tank back to "normal" that it would actually fit back on the bike.
So after taking his bike apart, and pounding my tank back to normal/a functional state--mind you it wouldn't even fit back on the bike previously-- then began the welding. However, first we had to make sure the gas was COMPLETELY out of the tank. The tank had been gasoline free for two days but we wanted to make sure. So we rinsed the inside of the tank with some Acetone, then I believe we used paint thinner, and then isopropyl alcohol when finally Mike decided to sacrifice himself to test for any possible remaining gas fumes by placing the tank in his front yard and putting a lighter practically inside of the tank.
I'm happy to report, Mike and his front yard are still with us.
Long story shorter, the weld took hold, it looks fantastic, the hole is sealed and the tank will function better than ever......well, until I buy a new one in the spring. Look for it on Ebay in April
(we had to "touch up paint" two spots on the topside of the tank too
A huge thanks to Motocycho for his time, tools, and willingness to help a fellow 9er get back on the road.
