Stock front end, just bolted on a second disc and caliper, and modified the speedo drive plate a little. Easy peasy. I'll need to play around with the MC...possibly go bigger.
Nope, both fork lowers have mounting points. The right side isn't finish-machined at the factory, so you'll have to do a little filing, and maybe add a washer or two.
If you can find a way to flip the forks around with the calipers trail mounted instead of in front, it will be more modern looking. Just a suggestion. I did it on a cb400f way back with a cb550 front end. The only thing that might be affected is the fender mounting. The only parts that will flip left to right is the forks and accompanying calipers & mounts. The speedo drive and wheel will stay the same direction and side.
That's the plan eventually. I have to bleed the calipers and drain the forks before I do that. With the switch, the fork draining can be messy, and the bleeder isn't the highest point in the caliper.
Situating the calipers behind the forks is also said to help the steering not be so twitchy. The weight in front makes the wheel want to fall to either side; in back, the weight acts as a stabilizing anchor. Plus it's much easier to wipe bugs off the forks instead of the calipers!
Ok, good deal! Sorry, I was late to the electronics posting. Did you work out the controller circuit for the damper? A quick glance looks like it just needs a pulse width modulation (PWM) signal. But then, the pot used for the damper should have varied the damper - if it was specified for it. How did you come about to order that pot for the damper? Was it required by the damper or did you read that would just work based on another forum/thread (GSXR?)? I'm not sure but it sounds like you may have figured it out. Usually a solenoid is on-off (coil and magnetic plunger) and a servo is variable (stepper motor and hi resolution controller).
No prob, yeah we got it basically figured out. I got my original info from a suzuki forum (gixxer nation I think? :) The damper works on it's own just with power, but I'm interested in being able to vary how much it dampens. So yeah, it's solenoid operated, not servo. The potentiometer was just a whimsical purchase, to try and make it work. Luckily it was cheap!
Hello again, I just wanted to share tonight's findings. During the process of the dual disc conversion, I tore apart the front end. This gave me an opportunity to pull the emulators and tune/modify them. When I pulled them, I was dismayed to see that one had oxidized. I'm going to assume that the tube with the oxidized emulator had water-contaminated oil, unless anyone has other thoughts. I'm not sure if I'm disappointed or not. There's no sign of leakage anywhere; the fork seals and cap o-rings were new last spring. Plus the bike isn't ridden in the rain. I'm thinking I'll just have to chalk it up to 37 year old forks.
In other news, I'm going to drill another low-speed damping hole in the top plate, back the springs off a half tune, and see how it does from there.
They're the MikesXS knock-offs. After all the diagnosing I've done on them, and cross-referencing with the sohc4 guys and their troubles, if I can't get them reasonably dialed, I might have to spring for the Race Techs... Here's to hoping they work (better) !
Hey Tim, out of curiosity, do you remember how you set yours up? I recall the instructions listing number of turns on the springs for "street" and "race" and I went half way between the two. High speed is great, low speed...not so much.
Or maybe if you still have the instructions, could you post the turn amounts?
I did mine a long time ago - would have stuck with the original directions - probably 1/2 way between like you did.
Honestly I don't know how to judge how well they work. Doug rode the bike in 2010 at Kiley's and he said it handled well, so I haven't touched it since!
Okay, thanks! So, hmmmmm. Since we're set up about the same, that throws a little wrench into things. Differences between 550 and xs650 forks aside, my vibration at 45mph may be stemming from somewhere else. I'm hesitant to make too many suspension changes at once because I want to pinpoint the source. Right now I've got the emulators backed off 1/2 turn, and extra unsprung weight from the second rotor. I'll test that combo out as-is and reevaluate. Fun fun.
