Motorbike, Welcome, You Are Doing A Bang Up Build. Glad To See The Tank On A Bike, I Got One Last Month, Black With Red Flames, I Think!! Lol. Yeah, I Remember Now, Black. Have Pics Of It On My Tailgate. Where And How Much For Cap And Gas Line Barb? $40 With S/h. 2 1/2 Gals Cap. I Like The Chrome Mirrow`s, Paint May Peel. Thinking About The Fork Tube. When Tube Is Threaded, It Weakens It Considerable. The Bracket Banging Away 2 Or More Inches Above The Bearing Nuts Is A Worryment! If You Have Or Could Get A Long Neck Tube To Extend Below The The Top Head Tube Bearings. And If The Locking Wedge Would Be Below The Top Bearings You Would Be Safe. It Would Also Reinforce The Higher Fork Spring Position. The Fenders Do Add A Nice Look. Have You Designed The Tank Mounts Yet? How About A Nice Side Pic With The Tank? I Would Like To Buy More Of The Tanks. This Addiction Is Bad!! I Remember When I Was A Kid, Would Paint Bike With A Brush And Hardware Hank 24 Hour Enamel And Ride It The Next Day Before The Paint Was Dry. Later Ron
