Ok, so maybe I've gone a little too far prettying up the starter motor...


I think that's the cleanest starter I've ever seen ;D

Finally something to talk about!  After a long break from the action Cliff Meyer worked up some more of his magic and delivered this beauty today:


I won't be able to play with it until this weekend but at least I got to check it out and hold it up against the bike.  My new welder gets here Thursday!

Looking great! make sure you get the shock mounting points in the correct spot (if you want to run stock springs.

I built the subframe how I wanted it to 'look' but it ended up not working with stock springs and I scrapped the mounting plates and dual springs and went with a monoshock   :P

Nice box! Its a great "shop" unit. Not too portable, but really welds well. I am partial to the Dynasty series, but they're pricey and then some. If my current unit ever dies, I'll be replacing it with a 280DX but the darn thing keeps kicking  >:(
Hoping to get quite a few good years out of it.  Couldn't justify or afford anything more at the moment!  I was pretty much set on a Diversion 180, but this will let me grow a lot more as I get better I think.  Have you ever dealt with Matheson for gas and wire?  Closest place to me and I need a bottle and some filler to start with.

Thanks, although I can't really take any credit for the hoop and cowl! Lol!

Not planning on running the stock shocks, but I'll certainly be as careful as possible measuring and replicating the stock mounting locations.

And that's coming from a painter.

I agree.  Maybe brush the finish and clear it, or at least show some of it off.

No turning back now!


After a couple test runs on the old subframe I got brace and started with welding on the hoop:


So far so good!  It's nice and level and centered up as best I can tell.  Need to pick up a 1" hole saw tomorrow so I can miter the stays and start welding them on, along with the shock mounts.

So far no blow through, but I'm staying conservative I'm in the 90s for amperage and not giving it a full pedal.  What do you recommend for amps?  First time with anything more than my old Century 100 wire feed, so total apples and oranges!  My welds so far are nowhere close to what I would consider pretty but I'm getting good penetration I think.  Dipped the tungsten a few times...

Thanks for the tips Cal.  I suppose it does make sense and is more consistent to go lower with the amperage but keep the pedal floored.  It does have pulse, I'll give it a go with some practice runs tomorrow.

Exactly, the new material is 0.083 so I dialed into the 90s and was throttling back a bit.  But being brand new at TIG it wasn't the best for consistency.  I only have the stock 3/32 tungsten for the moment.

I actually did strap it down close to the cut before I started but there was just too much movement everywhere to get a decent cut.  I bailed on that idea and resorted to the cutoff wheel/grinder and got it pretty decent after some fine tuning.  Done for the night, things started getting sloppy so it's time for food!  Got the shock mounts tacked into the plates before I called it for the night though.

Thanks Nils but I can't take credit for the vast majority of it, I just measured and welded.  Cliff Meyer is the man who made it.

Looking into a new battery for the project and my RC, and want to get into one of the newer lithium ones.  Question is, what brand?  Speedcell, Shorai, and Antigravity all make what I'm looking for for both bikes.  Pros and cons from everyone's experience?
