    Is this a good deal for a 1971 Norton Commando

    The bike is pretty much ALL original in mint shape. The price is 4500, it's in town. i have very little money but figure for that price I can't lose, i.e. i could re-sell it on ebay in a heart beat. What do you guys think?

    float adjustment

    In reading my manual I see that my float should be 24mm +/- 1mm. I get that, and i get how to measure it, however, I am curious about bending the toungue. If i understand correctly, I push the float to the top (bottom of carb body), and see where the tounge is. Am I correct in believing that...

    I was curious if anyone knows if a xs650 master cylinder can be used on an RD350, or for that matter if master cylinders can be swapped at all?

    Quoted 2 to 3 hours for a valve adjustment

    Called my local shop about syncing my carbs for me, figure they might do it for 30 minutes labour or something and save me some hassle. Told me they would have to set the valves first, so I say, "so an extra half hour for that?" he said, "no, thats a 2 - 3hours job" Imagine paying 200 bucks to...

    Building Manometer for barbless carbs: Where do I get a threaded nipple???

    So, I have carbs without vacuum barbs on the carb holders. From reading the carb guide I see that, "Also note the vacuum ports available on the 38s (arrows). A suitable threaded nipple can be installed in place of the block-off screw to enable gauge hook-up for syncing. This is only...

    Correct brake lever

    So, I'm not sure how many of us have snapped our brake lever, but I did. There was a wind storm late last fall that pushed my bike over during the night. it bent the front brake lever, and today, trying to bend it back, i snapped the thing. I see on xs650direct the alloy lever for the "Magura...

    Left side exhaust backfire: Too advanced? PAMCO

    Just a quick question, I guess, before I start troubleshooting carb issues. Can backfiring from one side only still be a result of timing be too far advanced? I set it myself, and thought I had it all lined up properly. Though there were a few (3) instances when I was kick starting my bike and...

    cam chain noise?

    This is my second engine in the same bike. So, it's a 75 engine in a 78 bike. I would not expect the engines to sound different... but on the new engine i am getting, what i think, is cam chain noise. I would describe it as a rubbing sound that you hear get more frequent as rpms go up until...

    Should I be able to switch gears w/o engaging clutch

    When i was first intalling the engine, and noticed i could change gears while not having the clutch engaged. I never really even tried to do this before, so I am not sure if it's normal. I know i can engage my clutch, say, at a stop sign, or i know i can shift more smoothly (normally) by...

    I'm sure many of you have been there, as a new rider, today was my first. Some minivan cut out infront of me and if i had been going any faster i would have went through the sliding door window. He actually pushed me into the other lane... I half considered chasing his dow until he had to...

    Safety relay causing bike to stall out?

    After swapping the 78 engine for a 75 engine, and installing the pamco, I managed to get the bike running, after adjusting the valves a bit. However, there are some issues, what I do know is if they are related At first it doesn't idle very well and I don't know if it would have to do with...

    this might be a dumb question...

    so, i managed to drop at '75 motor into my 78 special. I have it all mounted, but stopped for the night. I see that in between the carb holders and the motor from the 78 there were some thin gaskets that were glued in... Do I need gaskets to between the carb holders and motor for the...

    Sqealing sound, burnt oil, loss of power

    Yesterday i put on about 5 hours of 50mph driving at about 4rpm and it ran great until about the the last 30 minutes of my loop.... first thing i noticed was when i coming to a stop (slowing/gearing down) when i'd engage the clutch at the very end, it would just stall. So, i adjust the idle...

    (unpredictable) Flat spots off idle (78 special stock carbs)

    I've been reading through the carb guide and am considering experimenting with the needle and jet changes. However, though i understand that reading the bikes performance at certain RPMS is telling of where the issues lie, i.e. i have a flat spot around 5rpm that is almost always there. I...
