JesseeS Build Thread

So I got my sump extension in from Mike and got it installed. Only have a quick ride on it but thought I’d update.

Installation: A son of a bitch. Probably about an hour of fiddling around laying on the floor. The holes don’t all quite line up so had to drill out, check repeat until it all went together. I did not have any clearance issues as far as the kickstand but this is for my 75 which has had some tabs removed so YMMV.

Performance: night and day. The starter doesn’t take as long to get the bike turned over. Less vibrations. I mean at idle and cruising, all through the rev range. Speaking of rev range, you’ll be shifting quick. The bike now soars through the gears. Is it actually faster? Who knows. Does it feel faster. Yes. 100%. Also less engine braking which I quite enjoy.

For me it was well worth the money. Time will tell how things hold up but since I don’t daily drive this bike I don’t think there will be any issues. Once I’m moved into the new house I’ll get the bike on the dyno and see where it’s at.

I am speaking from experience. my ZRX had a sump with a cavity that extended quite low. Once I gave it a good scraping over a speed bump in a parking lot. learned to take it eazy after that

UPDATE: My riding season is over before it started haha

I got to take the bike out for a spin today. Started right up as always, rode about a mile and a half, slowed down to take a turn down a side road and the bike started sounding weird, like a 2 stroke when loaded up. Revved through the gears, still weird. Pulled over and dead. Went to start again and the bike started but the starter motor stayed engaged and kept running. Tried to kill the bike and it wouldn't die. Then on its own accord the bike died again. Checked connections, checked the couple of fuses I had, all good. Could NOT get it to start, having the m unit made it even harder as I couldn't get the ignition on. Somebody stopped by with a jumper pack, which would get the bike to start, but again, having the starter motor constantly engaged and once pack was removed it died. Got a ride to my house where I had a spare battery and jumper pack. Replaced the battery and it started up, although again, the starter stayed engaged. I said screw it and tried to haul home as I was a bit from home and the way home was all up hill. Made it about 3/4 of the way home and same thing, sounded like it was loading up then died. Pulled over again, tried to start and the starter kept lightly engaging as it was struggling to start (note that I'm not hitting the starter button during any of these starts, once the ignition turns on, the starter does as well) and what do I see but MY LITHIUM BATTERY SMOKING. So with a deep inhale I haul ass disconnecting and removing my battery, tossing it to the side. Inhaled it a bit which I'm sure took 10 years off my life, and my fat ass pushed the bike the rest of the way home. I'm tired, the bikes in the shed. I'm closing on the new house in 2 weeks, baby is due in two months, and I just won't have the time or energy to actually get working on the bike this season. So, I will design a new way to QUICKLY disconnect the battery in case of emergency. If anybody has any idea why any of this would happen I'm all ears and would love to get a list together of what to test when the time comes. I rode this bike last season and had zero issues, and changed nothing on the bike which is really having me scratch my head. Hope you all have a better season of riding than me!

That's a sack of crap, sorry for your experience @JesseeS
I will have a look over my M-Unit / Starter install and see if I can offer any help.
I removed all the relays from my bike even the starter safety disengage unit.
So my starter will stay engaged as long as I hold the momentary start button in. Maybe you still have your safety unit installed which has gone bad / shorted? or a short at the start button?

Well that sucks, dude. :(

Iirc, the start/engage signal for the solenoid comes from the M-unit, correct?

That is correct.

I also removed all relays from the bike

My thought process goes like this: the m unit needs a steady 12v to operate correctly. I believe because the battery had under this, the m unit may have gotten stuck in some kind of loop because of the less than perfect voltage. Now, when the bike decided to run my dash was completely dead, also l adding me to believe the voltage was too low. There was one point when fucking with trying to start it that it did not go into auto start basically. But only once. I was also running a lithium battery, and have a reg/rec for such. I’m wondering if maybe the reg/rec failed. Due to the fact the battery just died, and would continue to die, showing that maybe the charging system wasn’t charging the battery, and with it stuck in the loop overloaded/heated up the battery? Although I don’t know enough about electrical so anybody that knows more please let me know if I’m maybe on the right thought process

I'm seeing 3 ways the starter could have stayed engaged:
Starter button shorted or stuck in the on position.
Solenoid stuck engaged.
M-unit sending a continuous start signal to the solenoid.

Well... 4 if you count the start button/solenoid wiring pinched/shorted to ground.

I'd start (no pun intended) by bypassing the M-unit. Remove the wiring from the M-unit to the solenoid, run a separate batt lead to one side of the solenoid and another wire you can touch to ground. Test that way and see if the starter gets stuck engaged.

Not to be a debbie downer... but the starter motor ain't continuous duty rated... you might have roached it.

Surely they would have designed against that happening? You can't be the first person to ever run an M-unit with a "less than perfect" voltage.

Correct, Taffy’s battery was well down yesterday with no ill effects on the M-Unit. The M-Unit is self protected across all its inputs & outputs. If a failure of some components happens the M-Unit flashes that circuit. Unless of course the M-Unit has developed a fault (needs to go back to Germany for rectification).

Like Jim I think there is a short in the starter circuit somewhere as stated earlier.
It’s an odd situation that needs time to resolve; @JesseeS is under time pressure so it may have to wait.
 
Hey all! It's been a bit so I just wanted to update that there hasn't been much of an update. I ordered a new starter solenoid so I'm hoping there was just something crossed or shorting out within the old one. My second daughter was born July 22nd so am enjoying some family time and still setting up the garage. If I can sneak out for a bit I'm going to see if she will fire up.

Thats a fine looking family. Good luck with the garage set up too.
