    Rear Disc Brake conversion for 1981 SH

    That would be the quick and easy solution but unfortunately space is at a premium. The Talon hubs I have are *wide*. There's barely enough room for the rotor bolts to clear the swingarm as it sits...but yes, otherwise it would give me some relief. Yup, until I order up a couple of rims and...

    Rear Disc Brake conversion for 1981 SH

    I should also add that the width of the Talons makes it tough to find a suitable rear caliper. All the calipers I've got sitting around hit the spokes. I've converted some 4 pot calipers to twin pots with less than stellar results in terms of braking power. That's why I was originally hoping...

    Rear Disc Brake conversion for 1981 SH

    Why?...I'm probably just looking for a cheaper alternative :-) The Talons are vestiges from my YZ250 supermoto endeavors. That said, your suggestion is a sound one

    Rear Disc Brake conversion for 1981 SH

    Yeah...that's why I was hoping to have laced wheels with a rear disc. After lots of whittling I managed to get the bike down to 285 lbs with a constant loss lighting system. The bike that Skull posted is awfully sexy, and I have a set of RZ350 wheels I used for the bike's first iteration but...

    Rear Disc Brake conversion for 1981 SH

    I appreciate all of the input. I was hoping for a fairly simple junkyard-sourced conversion. I've been using some Talon hubs with 17s but the bike is too low; find myself dragging the frame. I'm looking to use 18s or 19s front and rear to get it off the ground some more. The rear brake has been...

    Rear Disc Brake conversion for 1981 SH

    I saw your edit. It appears from your link and what you're telling me above that I cannot go to a laced wheel with a disc brake...using XS/TX parts?

    Rear Disc Brake conversion for 1981 SH

    Tried doing multiple searches...and I can't imagine I'm the only person to attempt this, but can anyone tell me what I need to find - what model bike/parts - to convert my SH from a cast wheel and drum to a disc? I *thought* there were models out there with a rear disc and laced wheel. I'm just...

    Can I run a universal 12v battery and a capacitor?

    Please don't misunderstand me; the magneto I spoke of on my bike is a self contained unit for ignition only - it has its own dynamo and breaker point but does *not* provide power to anything else. My lighting system, when I have it on the bike, is a constant loss using a battery that I charge...

    Can I run a universal 12v battery and a capacitor?

    I dunno if you're running points, which may be irrelevant, but caps typically just store energy temporarily and won't have the ah rating of a battery. Both will absorb surges and both will provide power when the alternator isn't keeping up with demand, but the battery will last longer/provide...

    So Many Insane Prices - Just a Rant LOL

    I often wonder if I happened to get the last reasonably price XS out there. I bought mine in the summer of 2000 after seeing some street trackers on the web. I always liked the dirt track aesthetic and started looking through the auto trader; this was before Craigs list became a thing. I found...

    Do you think this would work?

    I can remember being shocked at how heavy/unwieldy a complete XS650 engine felt. The last time I had to deal with was when I was around 30, hale and hearty. But cripes was it unwieldy. I think I got some help from my wife or my stepson and most likely used Downeaster's laudably honest method. I...

    Fuel Starvation with Late Non-Vacuum Petcock?

    Your advice is well taken. I'll take a close look at them. The taper leading in and the outlet into the needle jet certainly will make a difference. I had an RD200 about 20 years ago that had Hitachi carbs. Air filters weren't available anymore and I couldn't find appropriate jets. Since it was...

    Fuel Starvation with Late Non-Vacuum Petcock?

    FWIW, I got an email back from Mike's. They're sending me another jet. I just wanted to give them public kudos since I mentioned the issue a few posts back.

    Fuel Starvation with Late Non-Vacuum Petcock?

    Yeah, I got my carbs from him and wanted to get the jets there too, but I couldn't find any listed on the site. I should've called - I'm sure he would have gotten me squared away.

    Fuel Starvation with Late Non-Vacuum Petcock?

    Not a bad idea and easy enough to throw together. I'm sure I can find a place to do this test w/out bothering anybody. In regard to shutting off, though, and this is just speculation, it's possible things could be leaning out (and yes, it does act lean under the circumstances I've described)...

    Fuel Starvation with Late Non-Vacuum Petcock?

    Yes, good idea. As I sit and smoke out in the garage with the cat, I contemplate what else I can try. The cat is no help on that but I appreciate your affirmation. I've been a little distracted though; I picked up another track bike and I'm trying to get it prepped for the next outing. I get...

    Fuel Starvation with Late Non-Vacuum Petcock?

    OK, so I just did a quickee flow test using the criteria above using a Ratio Rite and my cell phone's stopwatch. I also only used the hose for the LH carb because...I'm too lazy to investigate the difference between two hose flow and one. My guess is that one hose will flow faster the two though...

    Fuel Starvation with Late Non-Vacuum Petcock?

    I forgot to mention regarding the imminent seizure, It's possible that may have been happening, but when it would start carrying on I'd back off the throttle in hopes of letting the fuel level "catch up" and if it didn't actually go faster, it did run smoother after a bit. Unfortunately it also...

    Fuel Starvation with Late Non-Vacuum Petcock?

    You read my mind; I was planning on mentioning the tiny intake pipe as was walking back from my yearly job review. Chances are your suspicion is on the money regarding the one-size-is-good-enough design of the import petcocks. Sorry to hear about your Pingel; I've got one on each of my Harley...
