I laid my 2000 sportster 1200 custom down Saturday night going about 30mph when a car pulled out in front of me. I lucked out, very little damage to me or the bike. Mostly cosmetic. There's now only two issues I can't figure out that didn't happen before the wreck. First, at about 2-3k Rpms, the bike vibrates something awful. Any higher or lower rpms it's totally smooth. I've checked engine mounts, exhaust mounts and wheels. All fine. Idk what else to check. 2nd, my turn signals, brake lights, horn and speedo no longer work. I have no fuses to check. And I've read it could be the orange/white wires, but I can't even locate them. Im hoping these are simple fixes. As I'm trying to avoid shop if I can so I can pocket some insurance money for upgrades lol. I've posted here prettt much as my last resort before the bike goes to shop. If anyone has any advice, I'd appreciate it!

Also, I didn't mean to lay my bike down, but soon as I hit my break I did. And I think the reason is that if I slam my front brake at any speed at all, the forks damn near bottom out. So I'm sure at 30mph they did bottom out and it jerked the bike. Any advice on how to stiffen those would be appreciated too!

 

Firstly I hope you're all good after the crash.

Check your handlebar riser mounting bolts are tight.
Check your wheel rim isn't buckled.
Check your footpeg supports are tight and not touching exhaust on that side.
Run the bike up to the problem area whilst parked and see if you notice anything fouling.
Is the exhaust touching the frame, engine etc at that rpm?
Where are you feeling the vibration mostly...through the bars , feet , backside or all of the above?
What happened to the bike as regards the crash...lowside, head on, which side did you go down on?
Why don't you have any fuses? Is the bike customised? Kinda rare even on a custom bike not to have them though. I might be wrong but think there should be fuses under the small triangular panel behind battery on a stock bike. It's mounted on rubber grommets and should pull off. Should be approx 4 fuses in there including accessory fuse.
Depending on what was damaged and how you crashed would point you in the best direction regards what caused the accessory line to short out. Even something like an indicator bulb blowing could make a fuse pop.
The switch gear if they got twisted on the handle bars might have pulled the wiring and shorted on the bars athe switch gear body. There are a whole heap of areas that could cause an accessory fuse to blow and thinking logically regards how the bike fell and what was damaged will help.
If you do end up having a blown fuse and replacing it causes it to blow again the try isolating different areas of the bike. e.g. Disconnect the rear lighting block connector and see if it stops blowing. Disconnect the right hand switch gear connector, then the left, then the turn signal block connector for the front etc until you find the area of the bike that stops the fuse blowing and that should help you isolate the general area that is causing the issue.
At which point a more detailed examination of that specific circuit will highlight the issue.

Regards the forks, you've very little travel on them due to their design and as you say, when standard they're very soft but something like a set of Progressive springs and a heavier weight oil will help give them a more compliant feel.

Good luck.

 

Thanks a ton for the reply. I've taken that triangle plate off but it's just wires. Don't see any fuses. Though I read somewhere the older bikes didn't have actual fuses..idk. The throttle side did get bent and the handle pushed upwards. So I'll check those wires. The bike slid slowly on the right side, damaging the right side brake pedal, foot peg, both turn signals, and scratched the rear pipe. Also misaligned the forks, but I've since realigned them. When I have in neutral and rev to the bad spot, everything looks normal besides the shaking parts haha. The shaking is very visible at that trouble plate cover, the handlebars and front wheel.

 

If your bike is pretty stock then I'm sure you'll have fuses. Have another close look nder that panel although kinda hard to miss them. The way the fuse block is attached is to the back of the triangular cover and often requires you to slide the fuse block off of the panel. Do you see something that looks like a square relay in there? If so then your year bike should have the fuses there.
If it is just wires then take a look under the seat just in case you have circuit breakers but fairly sure that was on models a few years older than yours.

 

Found the fuses! One was blown. Everything working again right now. Hopefully no shorts! Now to find the vibration issue...

 

Nice job with finding the fuses & good luck with finding the source of this new vibration.

 

Make sure each fuse is plugged in correctly, and not between the fuse holder and the fuse housing. It is easy to miss. I found a similar problem just by accident.
