Agreed. Really appreciate all the info he's compiled and shared with everyone, but Robo-Boogie and I both hated his shock valving setups. Almost no rebound damping at all. Think I posted in more detail about that somewhere earlier in this thread, but was funny to see it come up again, and again.

I don't think I have ridden bory's settings enough to find what I think needs changing. However, there have been a couple times I have lost traction in rocky sections, and wonder if it a lack of damping causing that.

From what I understand, the objective behind bory's settings was to deal with whoops left by trophy trucks. So I am going to run some of that today, as I haven't had a chance to do so yet. So it probably isn't the best for everyone, but for desert riding I think its a good place to start.

The nicest thing about Borynack is that he documents & publishes what he has, how2doit etc, and hosts it even! Plus I have gathered his mods work, so that all makes him a good dude in my books


Ralph,

You realize that your rear light may be powered either by the stator's power or by the ignition coils? Both AC yeah, and if it's running on the latter this can well cause ignition modules to become consumables.
I'd find that fault - because, either way it is, if only because it clearly runs unregulated! - as my main priority, and I hunch that once fixed it would be the end of your woes.
Also, is the rear a LED-unit perhaps?

Another thing to keep in mind with Borynack's information is that people are doing this themselves, opening the door to mistakes and blaming set-up as the problem.

I think those completely unhappy with the set-up, or who see very little improvement must have done something wrong. As mentioned, it's not perfect but it's in a whole new universe in comparisons to stock set-up.

Yep, i have an LED panel inside the stock housing aswell as an enduro LED brake/tail/license light

Just my hunch, some others here (Crypto?) are more qualified I think: If that lot is powered by the ignitions coils or r/reg it may well stuff up the (electronic) workings, as there is a partial short between one half-sine only - as LED's are diodes.
But as said, even if not - you must get them to work on DC, as all the rest is too.
See it from - pun somewhat intended - the sunny side, they're going to be brighter!

I just went and got a couple tacos and checked the mail, and rode 40 miles of race course. Unfortunately, all the big whoops are gone, flattened by the monsoons. However I did find one section of whoops that I have ridden a few times and there is no doubt that I can ride them faster after the doing the rear (borynack). With traffic it was nice, the bike maintained attitude all the way through. Riding against traffic it felt like I bottomed the forks 5 whoops in a row before I backed off, but it never got squirley. Over the whole ride I felt like I bottomed the forks probably 8 times; one time for sure on a root, I thought I broke the rim. But it never got squirley like before. Some of the course is just big ruts with exposed rocks and I could stay seated where I could never before. It was also far less fatiguing as well.

I can't see where this setup has any room for complaints riding what it was designed for or where it could be comparable to a stock setup.

192 main

Jeebus, you must get about 20 mpg with that thing.

I bet it rips though!!

XR650R Oil Leak Can't Find Source.

Hey guys,

My new to me XRR has an oil leak that I am trying to track down before I finish my build on it and put it back together. The left side of the frame backbone was wet, not soaked but my wiring harness, coil and top engine mount were slightly oily/crudded up.

My guesses are either my upper right cooling hose where it goes into the thermostat (Is a little wet, new hoses on the way) or the dipstick cap may be leaking down the side of the frame.

Are there any common places to look for leaks in this area? Is there supposed to be an oring on the dipstick cap?

What are the two plugs in the side of the frame? Has anyone seen those leak before?

Thanks guys!

Levi,

Sounds like somebody spilled oil, it's easy to do when trying to fill it up. I'd use some brake clean to clean it up and keep an eye on it.

I have everything uphooked from the stator except the ignition power wires(black/red and brwon) and the trigger wires(green/white and blue/yellow)

This is infuriating!

ANy other ideas? When it died, the only thing hooked up was the taillight wires. Not sure why all of the sudden the wiring is being an asshole! Thanks guys
Did all these problems start to happen after you rewond the stator ?

Have you changed the springs or did the spacer mod/cut?

I find it odd you're bottoming so much. I have to work to bottom mine hard and if it's bottom otherwise it's doing it quite softly.

I cut my stock springs around 2" and put a spacer in. Please confirm that as I don't remember. I did add a bit of preload too, maybe 3-5mm. (spacer being longer than cut section of spring)

Yes, an easier way is to buy new springs, but at the time I was trying to save money (I always am), and have been 100% happy with the free mod.

I just rode my bike downtown for some posing and coffee (yea yea...) and even in town I enjoy the suspension. Keep in mind our streets are a lot rougher than you guys from the southern states. I even went out of my way to hit a few speed bumps, etc. Maybe did a wheelie or two.... I wont take credit for those.

Nope, rewound the stator 2 years and 5000 miles ago.

They are .49 or. 47 eibach, whatever was right at the time. The bottoming wasn't pitching the bike up, so it is questionable if it was truly bottoming, the forks felt like they came to end. except for the root which was like hitting a cinder block at 45 mph. I was originally running spectro very light fluid (like <5w), but then switched to maxima 3w after the shock rebuild. So the comp probably still needs some turning in. I would have expected some bottoming on the backwards whoops because they seem to be ran one direction and so the angle was a hard mofo at 40-50mph. There was a couple sections that were 15+ miles of whoops that I was hoping to try it out on, but they all got fillled in with the rains.

Btw, the best way to make rear shock run cool besides the rebuild, wrap the exhaust all the way back. The engine runs cooler too. Gained +8mph on my top end with the new exhaust.
