Topic: All you hard tail people...

Jag, when you run extreme rake, you get more interference from the fork to the gas tank. And that gets compounded ehen the triple tree is the height of the tank or lower..

 You either use a pointy tank, cut big reliefs into it, slide it back, or combinations of those things. That is part of the reason some frames are goosenecked, to build in room for the tank..

That makes sense, I just always assumed it had something to do with the travel of side to side motion and to keep it from contacting the handle bars. Or to help you from having to make caddy turns just to turn around.

Something else I am wondering is how to you keep the frame "trued up" after you cut it in half, if you don't have the ability to build a jig? I see that some guys keep the engine in the frame to help keep it centered, but what if you have to actually take it somewhere to have someone else weld it for ya? You can't keep the engine in the frame, it'd be too difficult for the welder.

And even though you want to use an Arc/Tig welder to weld the frame back together, can you use a flux (coiled wire that runs inside it) welder to weld on all your accessories, i.e. oil tank, battery box, etc.?? I have no experience with Arc welding, just the flux style.

On a longer raked slammed,  bike everything starts hitting, unless you have high bars.

If the tree was above the tank, you might get clearance with side notches, but lower the tree and all off a sudden the whole front of the tank is in the way.. so are your bats, if they are low.

 When a bike is longer, you need more/most of your steering lock to turn tight, ie parking lot.

Frame, unless only modding small portion, you should use a jig, otherwise it can move all over the place and never be straight.. it takes a logical thought out process to do it right.

Flux core wire.. as far as I know it is hollow wire with flux inside to aid welding.. probably on a coil, same as solid wire.. for mig..
 
 I am not much of a welder, but I think that is right.

So using the mig is okay for attaching oil tank, foot pegs, battery box, headlight, etc.?

Sorry if Im highjacking the thread it is Hardtail related though

True MIG welding actually uses a shielding gas, flux core welding is sloppy and works...but if you can afford getting a small tank of gas for welding mild steel and the appropriate wire I HIGHLY recommend it. It's a lot easier to weld with shielding gas too, but remember you use DIFFERENT WIRE when you use gas. Shop around but for a small tank you might pay 60-80 bucks including a tank trade in program. I get a big tank and refill it about once a year. I have one for stainless and one for mild steel.

The key no matter what kind of welding you do, go to a local scrapyard or metal supply place, get a bunch of "junk" they have leftover from other cuts and practice welding stuff together lol.

Well I had no idea that one could incorporate gas with the flux coil... Thanks a lot. I'm going to go pick one up then!!

Just to be clear, you have to make sure your welder can USE gas. Some are strictly for flux core. Your welder will have a clear plastic tubing coming off of the unit that hooks onto the tank. If I remember correctly most flux core welders are also MIG welders. Just make sure again you get the right kind of gas and wire for what kind of material you are welding. The right size wire/tip combo is important too. I found a welding supply place near me that was very helpful in answering my stupid questions when I first started out lol.

EDIT: VERY VERY IMPORTANT! read your welder manual, you might have to switch the wiring setup inside...pos and neg connections might have to be reversed if you are MIG welding instead of Flux Core welding!

Hey, build and ride what you want! It does help to run lower pressure in the rear tire tho. The guys here are rank amatuers when it comes to being opinionated. Try going on hdforums.com for a real laugh. I have a Hog as well as my CB's and those guys crack me up.

Dude I have a custom hard tail frame that nicer than anything you have ever seen!
I'm selling it for $500! If anyon eis interested email me. sbaker60@cox.net

Once my first bikes done the next will be a cb750 bobber. Hard tails look sweat.
