All I see is nice sharp edges and notches to act as stress risers for crack propagation in an area with plenty of load being fed into it.

I'd spend some quality time smoothing those edges and inspect it often.

Always dress your knots and deburr your machining!

Getting back on to this thread. Have some more funds coming in to change this beast around again. Rear wheel, Frame shock mount, bash plate, pegs, and a small windscreen will be on the way. Stay tuned.

I know you've talked about running some rallies--do you think you'll be up for it next year? I definitely won't make it this year but I think I've got the funds and insurance for 2015.

Whaddya say? Maybe don't buy that silly oilhead and use the loot for race funds?

You know ... I am seriously considering it. I have to sell a /5 (as soon as I install a battery and see if the clutch took a hit). And I am truly getting very familiar with the Dobber. Rode it to work today, and went for 30 minutes on dirt at lunch ... super fun.

We are adding a large addition to the house, but that should be complete by winter ...

Hmmmm ....

I'm starting to get serious about it. I want to get the front fork swapped out and start doing some regular trail runs to get it dialed in. I might also try to find some more formal offroad riding training. At the very least I'll watch neduro's videos several times in between trail runs. Jenna's got them. If you haven't seen them you should check them out.

Also, I'd like to get the 'race clothes' set up for the bike--new tank/seat/subframe--so that I don't have to drag that behemoth of a tank around with me. It wouldn't keep me from racing but that's another 40 pounds or so I'd drop.

Heck I ditched the stock fork a month after I got the bike. I might've demolished a pristine PD but 3 other guys finished their restorations in the process.

I'd go to the KTM forks in a heartbeat if I could get my hands on a triple. I'm e-mailing HPMGuy next week about any more spares and if there's nothing in that direction I'll call EMIG and see what they can do for me.

The bike's only part of the problem. There's a lot to learn to safely run those rallies. Stage is only a day's hard ride from me now. I'll spend some vacation days to give him a visit and learn me some things.

Did you end up getting new triples, Fred?

No ... The Stock DRZ triple is actually what you want if you are rally racing. It puts the forks closer to the head tube and is more stable on the straight-a-ways. The HPN triple keeps the same offset so that you still have the range of the BMW forks and is better for cornering. I have yet to have a place where I needed the tighter turn radius. So ... for the moment, I'm keeping the DRZ triples.

I will bet at some point I will up grade to the HPN design ... but not yet.

PS - I do have blue prints for the HPN design ... Know anyone with an 'aluminum capable' 3D printer?

Don't you get the best of both worlds with a stabilizer though?

My work-around for having a crappy turning radius is the centerstand. I pop it up, pivot around and vwoosh! I'm out the door at momma's basement

You gonna be around the weekend? I might try to ride home. I've got a set of jets I need to put back in the Mikuni box.

EDIT: I am NOT home this weekend ... Spaced a 'family reunion' in Asheville. You can tell I'm really looking forward to it.

Next weekend (31st and 1st) might be more fun though ... My family will be in Paris (without me ) and I'll be heading to Barber just for the day on Saturday to take in the chaos ... and maybe try out one of those obstacle courses!

And on sunday, I plan on a tech day ... I really need to do some maintenance on BB and get some upgraded parts on the Dobber.

And for the turning radii, I was more speaking while riding. You loose a total of ~12 degrees (6 degrees on each side) with the DRZ triple ... it doesn't really seem like a lot to me. And if you keep the stock swingarm, then it will matter even less. My has a 4" addition which does compound the problem a bit, but it's still not really noticable. I can pull a u-turn in the street using a lane and a half ... not bad.

PS - I have no experience with a stabilizer ... but you know that Stage calls it "The Hand of God". That's got to be good, right? I would hope so for the price.
