Having probs with my R6 .... need some help.

[CincyR6er]

Well, today I was driving to school and all of a sudden my bike backfired pretty hard and it shot me right into the tank with a good thrust. I slowed down and everything seemed to be fine as I continued along. I make it to school and the bike was parked for 10-15 minutes before I headed back home, however, my bike would not start. To me, it seemed like the battery was dead however I wasnt for sure. So I push start the bike and she starts up a little rough but I got her going. On my way home I came to a light and as i slowed down i noticed the gauges were not lit and the rpm guage was resting at zero. This only happened for a few seconds then as soon as I started moving again they lit back up. I managed to make it home ok but it did hickup one more time and thrust me forward. Once i got home I let the bike sit for a bit and tried to start it up..... everything started like normal. So I take it to beechmont motorsports and they said i may have a loose terminal and sure enough the pos. wire did need tightening. My question to anyone is do you think this was the cause of my bike not starting or could there be another problem? Since I tightened the positive wire it runs just like normal however I do not want to ride on it if I am risking damaging the bike. This is my first motorcycle so I am not too inclined on the mechanics as of yet however if anyone can please offer some adivce it would be greatly appreciated. Thanks ......

The loose wire will cause the battery to not charge properly. The system is staying running by the voltage you are generating. When you slow down the voltage drops and spark gets weak, light go dim... The problem is found. It should be fine now.

I have to agree you are fine now that you have found the gremlin. :)

[Rockybalboa50]

It was most likely just the wire that caused all your problems. The backfire was probably due to lack of spark for a revolution. Sometimes your starter won't turn unless you have a solid connection (short, lack of ground, etc). You ought to be fine now.

[CincyR6er]

Well today I started up the bike and everything seemed fine. I go on a 45 minute ride and pull over at a gas station to use the restroom. Five minutes later I get back on the bike and it would not start again. Same problem as yesterday. Once again I sweat my ass off trying to push start it and it finally fired up. It was about a 10 minute ride home and once I got home it would start fine. The wire is tight so I am not sure if that is the definite cause. Does anyone have anymore suggestion on what to look for or what I can do about this problem. Thanks for your input thus far ......

[RogCBR600RR]

Have you called BMS to see what they think since they took a look at it yesterday? Maybe a relay or something is loose or another cable perhaps :what:

[CincyR6er]

No, I have not called BMS yet since it happened today. They never took a look at it. I just described everything that I am detailing in here and they said to check the wires. Does anoyone know what I can expect to pay if I were to go have it looked at ?

[Booga]

You might want to check the battery, and see if there is still juice in it. My bike had problems due to a loose fuse, you never know.

[dualsport]

Check your battery. Fuses. All major connections. We are all just guessing. :confused: Are you anywhere close to my shop in Harrison? Can't fix it through the keyboard. but i'm trying!!

[jaruss]

Sounds to me like a battery and or charging system problem.

[In The Blood]

I don't know about everyone else but my luck with BMS has not been the greatest. Hate to say that out loud and these experiences where about a year ago. Things do change for the better sometimes. At least with dualsport, you do have some type of connection with LR.com. Good luck.

If you end up taking the six back to beechmont ask that ben kirk look at it for you. hes one of the only ones w/ his head and ass wired together. he'll set you straight.

[CincyR6er]

Turns out the battery is shot. I had my grandpa (retired mechanic) take a look at the bike and he ran a few diagnostic tools and said its definitely the battery. Thanks for all your help. Does anyone have any suggestions on place to get one for relatively cheap? So far cycle city is the cheapest at 71 bucks so if anyone else know any cheaper let me know.

[jetwrench95]

Give Bill at Holeshot a call. Just make sure he puts the acid in it before he gives it to ya! 859-572-0300

[Shane]

Yup got mine at Holeshot when it died. Not sure what I paid but it was the cheapest and they are WAY better than cycle shitty.

Do a search for Newcastle battery in PA. They used to have a shop across the street from my work, and had decent prices. Might be of help.

AFA as your connections, when you install your new battery, put some clear silicone inside the square part of the terminal. Then put the nut into it, install the screw holding down the battery cable, and put more clear silicone around the head of the screw to make it not turn out. I had a race bike that the screws would loosen. This kept them from turning out, and keeps water off the terminals. It will help with this problem in the future.

[CincyR6er]

Well i bought a new battery today and it turns out that is not the problem. Seems as though when I ride for a period of an hour or so the bike will want to die after that timeframe. Any more help would be helpful.

[SbRacer15]

Buy one of those Clymer manuals for your bike at the dealer. Then you'll have a wiring schematic. Have your grandfather help you find the charging system plug in your wiring harness. Try to read the voltage on the generator. Maybe it's not charging.

Maybe there is a grounded out wire somewhere, causing you to lose power. You may have to remove all the bodywork to inspect the harness more closely. Just some thoughts........

[Wheelie Monster]

Dude, I had the same problem. It turned out that I had a bad rectifier/regulator. Do these tests (or have your grandpa do them) and all your problems will be solved. I too thought it was my battery, and now I've got 2 of them, I was going to tell ya if you need a battery, I've got a new one that I only used once! :D

Okay, on to fixing your R6....

First and foremost check your main fuse for continuity and make sure your battery at LEAST 12.5 volts (12.8volts would be optimum)...if those are ok then.........

Grab your voltmeter and connect it to your battery... red side of your meter to positive and black side to negative....start your bike...rev it up to 5,000 rpm and look at your voltmeter, at around 5,000 rpms you should be seeing around 14 volts...(keep in mind, if your battery is not fully charged..you probably won't be seeing 14 volts)...if your seeing 14 volts, then your charging circuit is ok....if your not seeing 14 volts (and your battery is fully charged) then..............

Your gonna need to take off your generator cover..inside should be a 3 wire connection...all wires should be white...disconnect the wires at the connection and look straight on at the connector that goes back into the stator....they will be arranged in a pyramid shape with one wire at the top of the pyramid and two wires at the base of the pyramid...the wire at the top we'll call #1, the wire on the bottom right we'll call #2 and the wire on the bottom left will be wire #3..........Set your meter to read ohms....hold the positive side onto the #1 wire and the negative side onto wire #2...you should have a reading of 0.27 ohms to 0.33 ohms......keep the positive side on the #1 wire and move the negative to the #3 wire...again, you should have between 0.27 ohms and 0.33 ohms....if you don't get between those numbers on BOTH...then you need to replace your stator...HOWEVER....if the numbers on both look good then..............

You need to check every connection of wires in the charging system...if all connections check out ok....then you are going to need to get a new rectifier/regulator....


Hope this helps out, reply if you find anything!

[CincyR6er]

I am so glad you mentioned the regulator because my grandpa and uncle both said that sounds like the problem. Hopefully this solves the problem monday....

[Wheelie Monster]

It should! If it doesn't, then reply here. We'll get ya running the twisities again soon! :D

[ninjarider]

Did ya get the battery tested before ya bought the new one??

[Wheelie Monster]

The battery is going to test bad if the rectifier/regulator is bad as well. I tested mine, and it was bad, only because the charging system wouldn't charge it. After that was fixed, it now works good.

[CincyR6er]

Yes, i did get the battery tested before i bought a new one and I was told that I needed a new one. I think i could have actually gotten away without buying a new one however i have had problems with leaking. After taking another look at the rectifier i am almost definite this was the cause. The ground in the harness was absolutely fried so i replaced the ground and am going to put in a new rectifier monday as soon as i can get one. Does anyone have any idea of what i can expect to pay for the rectifier?

[jaruss]

I don't know for sure but I think that the rectifier /regulator assy. could run you around 75.00. I hope that the alternator is not fried as well.

[Motorsports Photo]

Motorcycle chargiung systems work by dumping the "extra" electricity from the alternator to ground. Since you found the fried ground, now you know it can work BUT.....

All those extra electrons could have fried any number of other sensitive components. It may take you a while to sort out all the bad ones before your bike is OK again.

Make sure that gound repair is clean and tight, and make sure there are no other melted wires/connectors nearby.

Be sure to check the connection where the voltage regulator plugs up, I have sean wires come out of the back of the plug.
I have sean two bikes do this, It will cause the battery to go down. Check the wires by tuging each wire at the back of the plug,Check for burnt spot inside yhe plug.
