Quick Shift Repair? Is it fixable?

Quick Shift Repair? Is it fixable? (Update) Fixed!

Here's my quickshift that failed over the past CVMA race weekend.

Is this repairable? Looks to be a sealed unit.
Green Wire is sad and not sure I can solder it back together.

I called Power Commander and the guy sounded like he could care less.
Said they are a sealed unit and they don't even bother taking them apart.

Not sure why the wires are so tiny coming out of the unit. They are bound to break over time.

Ideas?

Sorry OP can't help, but what are these for and what do they do?

Quick shift splices between your shift knuckle and your shift rod.
So you can do clutch-less up shifts while still keeping the throttle pinned.

When you shift it momentarily cuts spark imitating letting off the throttle for a split second. This allows the tranny to sync and go into gear just as if you pulled in the clutch and let off the gas.

(something like that)

Thanks

Hope you find your answer.

Well, the thing was assembled in some manner. Likely it is screwed together. I'd see if there is an obvious seam somewhere on the main part of the housing (one end or the other) that looks like where something might be screwed together. Then figure out how to grab on the two and try unscrewing them. You have nothing to loose.

I appears that it's a case of the wires bending back and forth at the point where they exit the housing. Careful mounting of the unit and subsequent management of the wiring cable will eliminate flexing at this point (you REALLY want to do this).

Good luck.

If you can strip the green insulation from the bit in that stainless housing and see some wire, then its definitely fixable.You just need to make sure they're completely clean and grease free, apply some flux, and with a hot soldering iron and some solder go to work.

I'd try that first before trying to take the housing apart.

Unless this is all completely foreign to you, and that part failing again could ruin a track day. In which case suck it up and buy the replacement, then mount it so the wires don't strain this time.

send it back to the boys at dynojet in vegas, tell them to replace it with a new one!!

I can solder, was gonna give that a try before i got all ape shit on it.
But yeah.. it actually broke when at the start of my last race. Front in the air and shifting to second... nothing. Went into T1 in 5th because I wasn't prepared. Red flagged on the 1st lap, came in and saw the broken wire. Second start went much better

send it back to the boys at dynojet in vegas, tell them to replace it with a new one!!

I called em and they could care less You have a number or a contact?

I pulled that same shit last sunday at the hill and i didnt stay on track for long! it was a ruff ride out throught the pasture but hell, red sticker season is up so i gata get my moto-x fix too you know! LOL the number is on there web, there pretty good about that kind of crap, it looks like its manuf defect!

From Dynojet in Vegas:

Unfortunately there is no way to repair that unit. They are pressed together and to get the case apart requires machining which in turn makes the unit scrap! Sorry we could not help. If you are interested in another unit call our warranty department at 800-992-4993 x1116 and we can offer you one at a reduced cost. Thanks.

Looks like I'll be hacking this one to see if I can repair it

Update...
Called and got a killer deal on a new unit. (Price of what you see used ones going for)

Make sure you route and fix the wire cable so that it doesn't bend back and forth where it enters the housing when you shift. That's what killed the last one. One possibility is to bend the wire back along the housing and use a beefy tie wrap to attach it firmly to the body of the connector. Then bend the wire back the other way in a big loop and fix the end to the frame or something. You want the thing to be able to move back and forth and have the wire movement spread out along as much wire lenth as possible.

So got the new sensor but it seems to not want to work... errr, right
Well it does, just kinda weird...
Pull type on SV650 w/ GP shift.
When up shifting you can see the actuator pull and all is well except it's not cutting the the spark. BUT.... it does cut the spark when the shifter is released and on it's way back. Make sense?
Up shift nothing until you release pressure and only THEN it cuts the spark.

Do I have the wires backwards? I didn't think it mattered which way the wires were, it's basically just a switch right?

 

[Indetrucks]

Whoops.. never mind.
Was using the Linear type with a totally diff. part number.

Update...
I went to town on the old quick shift and fixed it!

Works like the day it was new, just not as pretty
Pretty self explanatory what I did. Just took my dremel to it, ground down to expose more wire and soldered it up.
I threw some heat shrink tubing around the exposed portion and filled the exposed hole with silicone.
