Title: Bike shut-off while riding...k&n filter?
Post by: ccm900 on January 02, 2013, 11:04:07 AM
Ok I'm at work so I'm trying to make this quick. I just re-oiled my filter yesterday and I'm hoping this is the issue and not something else. But I let the filter sit out over night. This morning before work I was putting it back on the bike and noticed it was still pretty wet. I wiped off the edges and then blew out excess with my compressor hose. Put it in the bike, started it up, warmed up, drove to work...almost. I work about 2 miles from work...the bike shut off half a block away from work. It didn't just kill...it kind of sputtered like it was choking. I switched gears, it sputtered again and it shut itself off. I put it in 2nd and tried to start while rolling but nada. Pushed it the rest of the way to work and parked it. That's where it is now and I cant even focus at work right now. What do you guys think? Filter to wet maybe and choked it out? Or worse maybe? Or something completely different?

Will try to start it on my lunch...until then any suggestions or input would be awesome.

It's pretty unlikely the filter has anything to do with it quitting, I'd look for a pinched vent or fuel line first

+1 to that. You had the tank up to access the filter - so it's quite possible you pinched a breather hose when you put it back down. Open up the filler cap, run the prime cycle a couple times (just cycle the run/kill swtich) close the filler and it should fire right up of it is a pinched hose.

You'll still need to pop the tank up again and address the root issue - but temp venting via the filler is an easier way to check

Not completely understanding this. bike is 96 M900 FCR carbs

Went back out at lunch. Lifted the tank and checked the hoses. All looked well, put the key in, got power, kill switch dis-engaged, pressed starter button...nada. No crank nothing happened. Checked the fuses, all looked well. checked main 30a fuse next to carbs, busted. Bought a new one, put it in, started smoking and fuse popped. Bad ground? Would that have blown while riding and caused the bike to shut off? Or the ground loosened up while riding?

I don't think a bad ground would blow the main fuse.  Look for a short between that fuse and the fuse panel

Have you changed the battery lately?

If not, check the wiring for a short from the regulator to the main fuse.

do you have lights? are you missing any? do you have a solid starter? ok, now, one by one, check the 20 AMP Fuses those tiny modafaaackers give me hell last time...  [bang]

Haven't changed the battery but I have had the battery out to service it. A few weeks ago

Will check that wiring also.

I'll have to take a closer look at this

Make sure the battery isn't in backwards.

usual sympton of a dud reg/rect taking out that fuse

unplug the reg and try again with a new fuse

if it starts and runs then you have found your problem

When I put the new fuse in yesterday, smoke came up from the front of the bike. Reg/rect area...I may start there

 check the reg/rectifier -stator plug for a burn mark

Busy week, doesn't look like ill be able to get to it myself until Saturday :/
Using the family car to get to work for now. Now I remember why I end up taking things to a mechanic to fix, when its something like this and I need to get on the road ASAP that's the fastest (and usually most expensive) way!

Ok, found a few fuses, 7.5 ignition fuse that was blown, and a 10a fuse that was out. Going to replace those. But what the heck is this and where does it go? I've never seen it sitting out open like that. Is that possibly touching my steel tank when its down and blowing the fuse? I'll eletrical tape it so its not touching anything but I dont know where it goes?

I checked the wires from the regulator/rectifier and nothing looks burnt at the connectors. But I didnt put the 30a fuse in with it disconnected to see if its the problem

Being a red wire it is definitely a power wire, but I don't see any signs of it arcing. Taping it is a good idea.

The 7.5 A fuse being blown would explain why it won't run. What is the 10 A fuse marked?
Title: Re: Bike shut-off while riding...k&n filter?
Post by: ccm900 on January 05, 2013, 01:18:04 PM
There is no marking on the cover for the 10a fuse? Not sure
Title: Re: Bike shut-off while riding...k&n filter?
Post by: ccm900 on January 05, 2013, 01:22:51 PM
Just put in a new 7.5a ignition fuse and the 30a fuse after taping off that wire, smelt smoke and both popped. I don't get this electrical stuff, what now?

Disconnect the regulator as suggested before and replace the fuses and try again.

How long have you had it? What do you think of it?

I also came across this electro sport unit that ca cycle works offers
http://ca-cycleworks.com/esr515

Anyone have any experience with this one?

I've had it for...

15K miles maybe...maybe longer.

Electrosport is a good brand and ca-cycleworks is a great vendor.

Ordered the part last week and decided to take the bike in to my mechanic. I was going to have him do the valves and some other things for me anyways so I figured I'd just have him do this for me as well. My dad offered me his bike as a means for transportation until its done...I'm pretty excited!

I have no Idea! All I know is its a 92 I think 851, with fairings off a 888. Way different then my monster. Not nearly as much torque on the low end. But once I gets up there it screams. It's deceivingly fast
