    Been running Dano's QS for over a year now with zero issues with the electronics. The issue is with the shift rod. They comtinue to snap/ break

    The system was supplied with a dyno jet "D" shift rod. Its 88mm in length. This is pretty perfect for the shift actuator and my OEM rearsets...

    After the first one snapped after 3 months, I thought maybe I had it bound-up when I installed it. So i purchased a new one and made sure it was installed perfect and it wasn't binding.

    Fast forward 5 months later (today) and it snapped again while on the streets at a red light. Grrrrrrrrr

    I touched base with Dan (Dano's) and he said its because its cast aluminum and the bike is factory with a steel rod. Suggested that I find a steel rod from Bazzas.

    Bazzas only makes 80mm and 100mm that are close to what I need but either one is not exact. The 80mm may work if I can subtract 4mm from each female side. I haven't taken the broken one out to pull measurements but wanted to known if anyone had any other suggestions?

    I have no idea why these keep snapping. *Currently running std shift pattern.
    *bike is a K6 1000
    *OE Rearsets
    *Never down (knock on wood)

    most if not all the bazzaz rods can be cut shorter. sure your not binding the angle some how?

    Pretty certain. But something has to be wrong.
    Maybe the angle the connector is set on the gear box. Dont know what that is called.....

    The Bazzaz 100mm looks like there is very little threads to cut. I would need to cut about 6mm from each side.

    The 80mm seems life a ton of threads, but currently running an 88mm from Dynojet. So don't know if it's going to be to short to begin with.

    About to start taking it apart and pull sine measurements and see what's needed.

    The electronics are have been flawless. No complaints about them at all. Do wish the actuator was a bit smaller. Just got to figure out this rod issue.

    Well, something would appear to be off. I've been using aluminum shift rods since 07 with quickshifters on GSXRs with no issues at all, granted they have all been Bazzaz rods but aluminum. As to the angle on the gear box it is best to have 90 degree angles where possible, as in you should rotate the knuckle to where you have as close to a 90 degree angle to the rod as possible. If you have that wrong, once you rotate it you may find a different length for the shift rod itself.

    Make sure your shift rod is exactly 90 degrees to the shifter arm on the engine. We had the same problem with GSXR 1000's back in the day. A friend machined us a titanium one. Not a break since :)

    After looking into it further, the linkage is not at 90 degrees. More like 70.
    If 90 is at 12 o'clock...then mine is sitting around 11 o'clock.

    Got to figure out if an 80mm will work, when i put the connector back at a 90 degree angle.

    At the degree it was at, i pulled measurements on the broken one and found that 5mm was threaded into one side and 4mm was threaded into the other side. So, the 88mm rod had alittle room to adjust. But if i go with the 80mm bazzaz....i may end up shorting myself.
    If i go with the 100mm...i don't know if the threads are long enough to cut nearly 6mm from each side.
    At 25 bucks a pop....Hate to order both just to use one.

    appears to be threaded nearly the full length

    Thanks for looking for that. I went ahead a bought both units yesterday from STG. Had some in-store credits with them, so it worked out pretty well. Besides......i needed the male rod. The female wouldn't work.

    Well...back to the drawing board. Purchased a 100mm and 80mm from STG and they are back ordered until 6/6. So I had to cancel my order since I am scheduling a t-day for the end of the month.

    Called a few other vendors and sounds like the same thing across the board. Bazzaz is hold out. hahahahaha


    Thinking about just cutting my factory rod and tapping the standard side myself...... any thoughts to this madness?

    thing to know tapping yourself... one side will be std thread, one side reverse... so, you can spin and adjust the lever height. food for thought. Ski

    After adjusting the knuckle to a 90 degree angle, i have roughly 70mm of open space from face to face of threads. There is roughly 12mm of female threads on either side (bottomed out). That is a total of 94mm of space. The 80mm will give me only 5mm of threading per side and will have 7mm Female threading left over per side.
    Some blue Loctite and a locking nut should assure nothing moves.

    If this doesn't work.....I'll be contacting Bazzaz directly and see if I can get hem to ship the 100mm and cut what I need.

    Found a vendor that has 1- 80mm in stock thank gosh.
