Only runs while start button pressed....

hey everyone,
just installed the mosfet rr and did the tuxedo stator mod(with the help of gcextreme, jack fleming and tim parrot!)...everything went pretty smoothly and got it all back together...pretty straightforward and highly recommended! but now have an starting issue...

the bike will crank and start, but will only run WHILE i hold down the start button...as soon as i let go of the start button it shuts off.
it runs fine, headlight comes on(after the mosfet headlight tweak), i can rev while it's pressed - but the starter is obviously still engaged.

ive seen a few posts with the same issue on the web but havent found any conclusion...
ive gone through the connections visually and they seem fine.

anyone have any ideas?

thanks!

I'm guessing you are losing the blocking circuit from the TCI....
Check the side stand switch for propper operation.
Bottom line is that pin 14 has to be grounded at all times for the bike to run.

I have not studied the schematics for this issue....

I suspect........could this be an Ignition switch issue ?

???

The coils and ingnitor both get their power from the same line off the ignition switch..... so I wouldn't think that was it..... (the bike fires up) but I wont rule it out either...

If there isn't a switch, is the harness still there?
Either there is a switch or someone jumped it out....
Pin 14 means on the junction box.... 10 pin connector, on my bike it was the black/white wire.

The kick stand comes in on pin 16, green/white wire....
with the stand in the up position, you should have continuity from pin 16 to ground.

^ good luck
Is the bike in neutral when you start it?
Does the neutral light come on?
Please go into a little more detail, like clutch in or out, stand up or down, ....
Maybe you disturbed something doing the R/R upgrade?
