Now to get caught up to present day...
In the middle of August, I was riding my bike on the interstate for the first time. I hadn't had the bike up to 70-80mph for more than a few seconds a this point. It was doing great for about 5mins before it surged a little then the engine completely died. I coasted over to the side of the road and the bike wouldn't start. The starter would engage but it wouldn't turn over. I trailered the bike back to the garage and didn't have much chance to work on it until a couple of weeks ago.
The first thing I suspected was the fuel pump. I wouldn't come on when the key was turned. I pulled the pump out of the tank and found this mess.
In hindsight, I should have tried soaking the pump to see if it could be resurrected but at the time I opted to get a new pump from one of the eBay links found on another
thread. I picked up a new bracket and vibration dampener from them as well from Euro MotoElectrics (Part numbers 16 12 1 464 629 and 16 12 1 450 712). I replaced fuel filter and the gasket ring for the petrol gage as well (61 31 1 459 448). I cleaned out the tank a couple times with vinegar and scrubbed it with a brillo pad and it cleaned up nicely.
With the new fuel pump, the bike would turn over and run for a second or two and stop. It was at least it was closer to starting than before. I checked the injectors next and found that three were spraying weakly and the fourth was barely at all. Instead of sending them off to be cleaned for $18 a piece, I bought new injectors from Osidetiger. I figured it was a good excuse to do the upgrade.
I installed them this weekend and they've made the bike idle a little better. It'll run upwards of 5-8 seconds without dying now. It runs better without the choke being on at all and if I give it any throttle, it dies immediately. I went through the "Cause of No Start" guides and cleaned all electrical connections I could find. I pulled the sparks plugs and they were flooded but looked to be in good condition. I did, however, break the forth spark plug wire when remove the cap. The wire had rusted and fell off really easily. I swear stuff just breaks when I touch it.
Then I risked a fire by spraying carb cleaner around the manifold/throttle body trying to find an air leak but without success. I went to check the Z shaped crankcase breather hose that a lot of people have problems with for cracks only to find it wasn't there. I found this in it's place.
Here's where it connects.
The hose runs from the crankcase up under the front of the tank. The little pod filter was also oily as all get out. Where the Z shaped hose usually connects to the TB, there's a rubber plug/cover that's hose clamped to the TB (forgot to take a picture).
What been trying to do yesterday and today is test the fuel pressure regulator using a gauge setup from Harbor Freight but the darn thing won't stop leaking. Nothing like getting misted with gas. I even returned it and got a new one but the second one isn't much better. Couldn't be user error, right? :falldown: On the best seal I was been able to get, the gauge read 40 psi for a few seconds before springing another leak. I'll try getting some different hose attachments this week to see if I can get a better seal.
My next thought is to follow this guide to try to find some electrical issue unless anyone else has other ideas:
