    BS-38 Carb alternatives?

    I had hoped the EX-500 carb conversion in http://www.xs650.com/forum/showthread.php?t=13070 would work on my TX750. Unfortunately the center to center spacing for the carbs is 125mm instead of the 120mm on the 650 and the ganged EX-500 carbs won't fit. Are there any suggestions on a better...

    BS-38 Carb Issues?

    TX750, stock BS-38 carbs and jetting, exhaust, intakes. On the last two tanks of fuel I've noticed the engine wants to idle around 3500 rpm as the tank gets to the reserve change over level. Once it's switched over to reserve the idle returns to normal. The engine starts and runs fine when the...

    Sudden Poor Running Diagnosis Help Wanted

    Yes, it's the redheaded relation to the 650, but I have a diagnosis question for my TX750. After getting it to run well (previous posts here), I was riding it after filling with fuel. About 8 miles after the fill up it was like a switch was throw. I was cruising at 45 and the engine suddenly...

    Carb refurbish = worse fuel economy?

    I actually posted this question in another thread http://www.xs650.com/forum/showthread.php?t=32243 but didn't get an answer so am asking again. Well, it's time for a follow on question. I serviced the mechanical advance, re-checked the points gap/timing, valve clearance and cam chain...

    Starting/running issues

    I have a '74 TX750 with a couple of starting, running issues. The first issue is after starting and until the engine warms up it doesn't want to rev beyond 3000 rpm, choke (starter) on or off doesn't matter. The second issue is hard starting when warm after a short shutdown, as in a fueling...

    BS38 Mix Screw Question

    Reading the carb guide it describes removing the mix screw and spring for the BS38 and the mix screw, spring, washer and o-ring for BS34. A couple of Suzuki rebuild guides also mention the washer and o-ring. I actually have a '74 TX750 with the BS38 carb, but wonder if they should have the...

    Wanted - Cap and bushing for dual disc brake master cylinder

    I cleverly rode off with the cap loose and have now lost the cap and bushing for a 22mm dual brake master cylinder. So, I need part # 341-25852-30-00 (cap) and 341-25855-30-00 (bushing).

    Early Brake Pad Question

    When fitting new brake pads in the early style caliper how loose should the pads fit? The ones I took our were quite snug but the new ones will fall out on their own even with the shims installed.

    Brake Shim Question(s)

    I'm adding a second disc brake to the front and rebuilding both calipers in the process. Do the shims that fit between the pad and piston go toward the back of the bike so the disc rotates over them as it enters the caliper (as the parts diagrams tend to indicate) or toward the front of the...
