I was going to wait on putting in Gold Valve emulators until after my trip, but the install is so simple and I need to come up with a shim for some preload anyways. Why not use that emulator for a shim!

from what I can find those forks you've got use damping rods and could benefit from cartridge emulators. ~$150 If you've got your plate full with other things it may be best to wait on details like that though. Suspension tuning can get kinda involved.

I've read GOBS on suspension and I'm barely starting to figure this stuff out. I've done a few things to my suspension according to the book then taken it down my favorite set of bumpy powerline trails to try to get a 'seat of the pants' understanding of what's on the page. I could get used to this kinda research!

One thing I see over and over again though--more wheel travel is pretty much always better. I think you've got that taken care of! Offhand it seems like your static sag isn't much so your bike is too stiff. Can you adjust anything other than preload on those rear springs?

That's the glory of the Ohlin's, on the fly compression and rebound adjustment.

man I need to get work on this dang Spanish Essay. I should be reading The Cat in the Hat in Spanish, not 16th century poetry. Now I have to write 5 pages about it. I think I can write 5 pages about how much I HATE 16th century poetry, not much else though.

Eventually. Its title-able. In the five years since we started the project I lost the front plate on the frame. But I have relatives in Vermont, so for a minimum of paperwork I thin I can get it official. I was thinking just a seperate battery for lights, a magneto, or, god forbid but the thing can still accept a standard charging system. I am thinking of getting it in street legal form for Rallymoto-- Smithy you hear me?

Yup. and Yup! sup I wonder if I'll even need fourth.

Yeah its got little two part pod filters right now. I will need to devise a higher altitude intake. For now I'm in get it running mode. I'm not a submersible yet Future.

and I've heard that Vech guy knows all when it comes to the real dinosaurs

3400 Earles Fork Road, man that's great

gotta be a modern(better) alternative, but I didn't turn anything up
I had found those links myself in my travels.
Yeah the /2 plate magneto sensor plate can bolt up with some imagination. and I hear the center spindle of a stock rotor can be pressed out to make a magnet holder, or something...
So I think it can be done. Meanwhile, an inmate here has graciously given me a good deal on an small AGM that I'm going to use for the initial flights.

I DO wish somebody woul tack a "/5 Dirtbike project" or something on the end to give even the barest clueof what I'm talking about.

Yeah! I'm going out to BC next week, so I am leaving at Havspeed to get its feet tacked on. I offered to make the brackets, and he said "you know, the rest of the bike is so nice, why dont you just let me make the ears for it?"

I'm not sure if I should be offended or not

But I'll let him let it clutter up his shop for another week and a half till I get back. Thats how these things go.

that looks a lot like something you could mount over the crank nose.

I would love to have six or eight different kinds just sitting around that I could pop on and off.

Oh my god I cant even think suspension tuning yet. I will say I think the emulator becomes a part of your shim stack, whether you like it or not.

Although I did find an SRC fork brace for this thing (provided what I have is really an XR250) that runs about $165. Thats pricey, but I can see it making a big difference.

I thought these forks were cartridge for some reason, but you could very well be right about them being damper rod.

The rear springs come in two parts, a shorter length one and a longer length one, and I have a few differerent choices, and that would be spring rate differences. The shocks also have a compression setting. I think thats what it is.. the stiffness.
I dont think a 2"drop over 11 or 12" is too stiff... but then again, I have yet to ride it. Oh and also I have only everything to learn about suspension.

Guy who built it said he dogpaddled it around for a half hour two seperate times... said it was a real hoot. He used a I.V. type thing for a gas tank. The reason I'm reluctant to out him is that I dont know what his situation is with regard to his job- and while its probably not really a secret I dont want to broadcast..




mike: BRING IT ON



Oh, and I googled GSX-R 600 stock exhausts-- they are awesome at right about $20-40 bucks! I think if I dont try and get this giant BMW anchor nailed to the side of the bike, that might be a sweet way to go.

ANd so while I while away the hours of cold and dark and February slowly drags on, I try to visualize why I never bothered to learn a better paint program that friggen MSPAINT.

White frame, White tank, Red stripes:






But my girlfirend says I shouldnt just re-create the PD, SO

White frame, Black tank, Red stripes:






somebody mentioned leather seat, and there is a brown color in the choices, so I thought "ITS KISMET"

Then I thought holy crap, I forgot the fenders:










After that I got really crazy and decided to flip the rear brake lever up to see what it would look like.



See how high up I'm going to need a peice of steel to go from that pivot point? THe good news is that I can probably use the area in back of the frametube there for a pedal stop, and maybe a height adjust. I cant decide if its best to have the pedal go outside the frame under the pedal, or outside the frame over the pedal, or inside the frame, next to the tranny. I think I kinda like the last one the best.

but she'll make you buy her a new pair of shoes every time she gets a new purse so they'll match. women!

Here's what I've read on static sag(also, this is what the folks at Dan Kyle Racing said to do with my Ohlin's:

With you and a full tank of gas the spring should compress between 1/4 and a 1/3 of total wheel travel. 1/4 is stiff--more street, 1/3 is plusher--more dirt. with 12" of wheel travel you should lose 3-4" with you standing on the pegs

dual rate springs are going to make that all kindsa more complicated. I'm clueless about that part. but NORMALLY, you get the sag right then go riding and adjust the damping til it feels good. You want to bottom out on the hardest thing you plan on hitting(that 25' ramp we were talking about) then stiffen it up just a little bit

http://www.worksperformance.com/html...rate_desc.html

http://www.tootechracing.com/suspension_tips.htm

from http://www.dirtbike.ws/node/43

Quote:
The front suspension of the 96 XR 250 only has compression damping adjustment, it is hidden at the bottom of the fork leg underneath little rubber plates within the hex style bolt head. Always be sure to bleed the air out of the forks before every ride, as it can cause a lot of harshness when riding.
if you can adjust damping, it must have cartridges

lemme get this straight, the reason you can't use the stock brake pedal is because of how steep the swingarm axle is now? you probably wrote that somewhere and I'm just not seeing it. hmm....

Have you ever gone this route before? I heard VT was easy, but do you need someone who lives there to do it?

Jason - we know that you are partial to the vintage BMW "Sherman Tank" look but can I suggest using 1970's motocross bike tank/seat/fenders? Could save a few pounds too...

Hey Guys-

I just found this and am hyperventilating




from here:

http://www.wilddog.za.net/forum/index.php?topic=23723.0


yeah- I think I can get it titled and reg'd in VT-- I will check it out when I'm ready to jump off that bridge.

And Smithy- I have a supply of about 5 or 6 different fender choices, (including some Preston Petty Mudders) and two or three tank choices, right now, so when I get the unit back in my barn I'll throw a few at it and see what doesnt fall right off.

Dear SH

that other site // thread was a complete waste of time !! ... or so my wife says. It took me awhile to look @ all that pure porn!

BUT did you notice how "Eddy Hau " had his rear brake done on his HPN Dakar?? looked like a cable set up.
cheers!
