$100 907ie

Post by twd46 »

All,

I recently purchased a $100 907ie. It hasn't been started in years. My plan is to clean out the fuel tank, change oil, and new plugs. What else should I do before attempting to start it? Thanks.

I think the best thing would be to sell it to me for $200 ,where else can you double your investment in such a short period of time !! Apart for Bitcoin. lol . What a score !

Haha. Thanks for the reply. I had already planned on doing that. The engine has compression and I changed the oil and there are no metal flakes. Now I am cleaning out the fuel tank. All in all, so far so good. The most puzzling thing is that there are about 5 cables with the positive cable. Is this normal? Ive never seen this before.

sounds like the po did some changes or additions. You will have to trace them out to see whats been done.

I have 3 on the battery ground and 3 or 4 on the positive for changes and upgrades I have done sorting things out over the years.


upgraded stator and regulator, headlights and an air horn just of the top of my head


ps. bump his offer to 300 :smoke:

Very interesting. Thanks Higgy. I assume that I just connect them all together on the positive battery terminal, correct?

According to the wiring plan there would be 3 wires on the battery's + terminal. If you connect them together better be sure what they are for, specially if they are not red.
I really wonder what a $100 907IE looks like and why it was stored.
The list of things to do to resurrect a 907ie is longer. Was the tank full or dry? If it was dry or almost empty there might be fuel residue that dried in the filter and/or fuel pump. Check the tank for rust, flush it, replace the filter and when you filled up the tank disconnect a fuel line to the injection system and switch the ignition on just to see if the pump primes. It's possible the injectors may need a cleaning, too. As for the engine. If the belts are replaced the valve clearance should be checked as well. It may make sense to squirt a little oil through the spark plug holes, put the bike on the center stand and in gear and turn the rear wheel several times to turn the engine over. You should be good for the first attempt to start it.
Later you should probably go through the whole bike replacing brake fluid and lines (if the are still original rubber), rebuild the fork, check steering head bearings etc.

I would like to know what they are supplying first and if they are fuse protected and grounded properly to prevent an unintended consequence. Fires are common on such older machines. Rodents enjoy chewing on wiring

Excellent advice. Thanks for the help. Ive already performed some of those jobs. I would like to post some pictures, but the image is too large.

Resize it to max 1024x800 and a max size of 1MB per picture and it'll work.
If you don't have a program or app upload the pic i.e. here https://onlinejpgtools.com/resize-jpg set jpeg-width to 1024 and save the resized jpeg. That you can attach to your message.

Thanks for the help paso750. Here are a few photos of the bike.

It looks a bit rough but a good basis for a restoration. Finding the missing parts isn't a problem.

100$ ? is a no brainer , Ispent 350 for my 750 some years ago, I though it was rotten instead I got it back on the road with less than 500$ and then sold it for 3500 (could not keep it unfortunately)

So I changed oil, belts, spark plugs, and added fresh fuel. I tried to start it today with a good battery but to no avail. The headlight and dashlights come on. However, the fuel pump doesnt prime and the engine doesnt turn over. I do hear clicking when I turn the ignition switch to off or on positions, but I hear no clicks when I hit the starter button. I read in another post that if the kill switch isnt making good contact, the fuel pump wont prime and the engine wont turn over. Is this correct or should I look elsewhere? Thanks in advance.

Have a look at the wiring plan. The kill switch connects to one of the two fused relays. You should check their 15A fuses first and then all in the fuse holder. Check them with an ohm-meter not only visually as sometimes hairline cracks can be overlooked.
Disconnect the yellow/red wire from the starter solenoid and check if there's 12V on it if you hit the starter button. If there is you should hear a click when it's connected back on the solenoid. If there is but there's no click the solenoid is not ok. If there is and you can measure 12V on the wire to the starter, the starter motor is not ok. The brushes could be worn or in worse case the windings shortened.

Edit: As I just saw in the wiring plan the 12V that are passed on to the starter solenoid when hitting the starting button come from one of the two fused relays so definitely start there.

Did you ask the PO why the bike was stored? Was a defect the reason?

Thanks Paso 750. I looked at the wire connected to the starter solenoid and there was a tremendous amount of rust. So before I do anything else, I am going to clean all the electrical contacts I can find including grounds. After that, I will try it again and see what happens. If it has the same behavior, I will do what you say. Thanks again.
