Ever strap a petrol tank to a cement mixer with nuts and bolts or a chain inside to clean the inside? LOL.
i just pick 'em up and start shaking them for an hour or so.... the last tank i cleaned was from my van... it was a bit heavy compared to an M/C tank.
the Kreem Kit use is always fun... trying to evenly distribute the lining goo gets tedious, and tests my iso-strength well...
the cement mixer is a good idea, as is using a loose chain.... the screws/bolts tend to have lots of sharp edges that help chip loose rust and varnish, especially in the tight corners.... the chain would help with impacts as the mixer rotated... and be would easier to get out... there's always a few loose screws that need extracted with a magnet.
i've watched amateurs spend hundreds of dollars replacing every part they suspect might cause a misfire situation, then a squirt of WD or carb cleaner/brake cleaner/etc locates a massive air leak, solved by a five dollar gasket and some silicone, or a few feet of vacuum hose..
