Topic: Fuel injection conversion (edit) fixed a few things

here's a 3d of the shaft. there will be a half circle shaped rotor on the end of this for a trigger.

Would like to use a tappet adjust cap for the cover

That would be awesome.  Hope you can make it work!

OK guys I'm still researching my EFI project so I have a couple of questions for you. It looks like most of you guys are using temp sensors placed in the fins of the head or mounted in the head for engine temp for the warm-up tables. Are any of you using an oil temp sensor instead? It seems like the oil would be a better indicator in an air cooled motor. I would like to hear your thoughts on this.

Next question is did any of you install a tip sensor? I know most modern EFI bikes have them. I found a 600rr one for $50 and it would be easy to wire into the main relay for the fuel pump and ignition. Once again I would like to hear your thoughts.

I tried an oil temp sensor at first, didnt work well. Rate of warm up varied too much from different outside temps and it didnt cool off fast enough after shutdown. A tip over sensor is a good idea, im not currently using one, should add that to the list for winter projects.

What do other air-cooled EFI bikes like Ducatis and Harleys use?

[750essess]

google is telling me they use cylinder head temp sensors.

23T,

Does that netbook have a solid state drive or a regular hard drive? If its solid state..(memory card) then you are good to go. If its a traditional hard drive you will probably destroy the drive riding down the road with it running. Traditional hard drives will take some shock while reading or writing to the disk but I would think being on end and the shocks from riding a motorcycle down the road could cause problems. Just a heads up. Then again I'm usually overly cautious too.

He won't need a solid state.  Even a platter HD has shock and lateral load resistances.  Although I love my raid 0 SSD's on my desktop

Anyone have anymore info on this alternator conversion?

Are you talking about adding an external belt driven alternator or are you referring to changing the stator and rotor with more modern ones from a different bike? If it is the latter I'm working on using 600rr parts in my CB650 and will post up a complete step by step on how I did it once it is all complete. The author of this thread used a VFR800 stator and rotor and his info is in this thread. As for the external alternator there have been a few around here that have done it but I think you are pretty much on your own to figure it all out as each one I have seen has been setup differently and on different bikes.

[hellbilly1932]

yes, sorry i wasn't clear, talking about the vfr rotor and stator conversion. I was reading your thread also and look forward to seeing what you come up with. Any reason you chose those particular parts?

[65Ch3v3LL3]

Since I'm using the 600rr throttle bodies and sensors (TPS, IAT, MAP, and Tip over) and I'm using the hand controls and fuel pump I picked up a complete wiring harness for a 600rr so I would have all the correct plugs to integrate into my MicroSquirt ECM harness. Since I already had the harness I decided to get the regulator / rectifier and stator / rotor also. It looks like its going to be a good fit for my application and is more than likely pretty similar to the VFR parts. I figured if it produced enough current for the 600rr that I pulled all the parts off of then I would have no problems powering my bike.

That shouldn't take up as much room under the cover as well, i would love to shave some width off the stator cover....

Will you retain the electric start.?

[65Ch3v3LL3]

Yes its much thinner than the stock rotor / stator combo. We are planning on making a new billet housing that will mimic the original but be thinner. I'm also planning on making it like the 750 housings so that I can bolt on different covers. If I could get my hands on a 750 lower case with crank we could also R&D a billet housing for them as well. The shop that is doing the work for me is a metal fab shop with full CNC capabilities and will do runs as small as 10 units each so if there were demand I could possibly put it all together for you guys. But be forewarned its going to take some time since I'm in Afghanistan so patience would be required.

[750essess]

I apologize for the vague dimensions on the alternator conversion. I didnt document it well. I basicly had the machinist make and adapter for the flywheel first. After that measured from the engine case gasket service to the front of the rotor. Using that measurement plus a little for clearance measure from the cover gasket surface to determine the depth the stater needed to be at and built a spacer to adapt the hole pattern and set the depth. I small cutout area for the stator wires to clear and thats it. Ill dig through this thread and see if the pics are still there

[750essess]

The pics are on page 9. Also I forgot about the starter clutch...the flywheel needs drilled and tapped for that also.

That would be nice but i think for my K2 at least, i will probably just cut the difference out of the original cover, i just had a billet "RSC" cover made up for the alternator side, and i am definitely using it, now my F1 is a completely different thing...   What would be better is to make a stator and rotor kit for us to buy that retains the electric start, it would be a best seller ....   Have a good new year Chevelle....

[hellbilly1932]

Thanks for the info guys. My best friends brother works in a CNC machine shop so we are thinking of going that route. Neither of us runs electric start so that takes out one step. My friend is great at aluminum welding also so we will see about making the cover thinner and therefore not need to make the adapter bracket so thick.

I'm watching some parts on ebay now!

[65Ch3v3LL3]

One thing I would like to add to the "database" of information in this thread is through my research for a fuel pump I found the late model Triumph pumps. The two I looked at are from the Bonneville and the Thruxton. They are a bit pricey but for those of you that want to keep a stock style tank without the issues of running an external pump it might be a good option. The pumps mount to the underside of the tank in the middle of the tunnel. The pickup offsets to the side and is mounted low which would put it approximately where the petcock goes. It would require some metal fab to cut out part of the tunnel and weld in a flange for the pump assembly but the outer shape of the tank could remain the same. Now I haven't tried this personally and I'm only going on theory here but it looks like a great way to go.

Very interesting find 65Ch3v3LL3.  If the plan was to do a custom tank, that would be a very clean install.  Thanks for posting that.

+1, nice detective work mate.....

[Terry in Australia]

Geez that's a lot of gear to stuff in a SOHC tank, also, you might run into problems with the frame's backbone interfering with the positioning of the unit inside an SOHC4 tank? Cheers, Terry.

[65Ch3v3LL3]

From looking at them I'm pretty positive I could fit one in my 79 CB650 tank and the 750 tanks are similar sized. But like I said its just conjecture at this time. I'm going a different route or I would try it but I just wanted to throw it out there as a possibility. I have a few 650 tanks laying around. Maybe one day when I'm bored I'll give it a shot!

[Terry in Australia]

No worries mate, and I'm not trying to pee on your parade, I'm just looking at the flat bottom on that Triumph tank and trying to think where you'd mount that gear under a CB750 tank. Cheers, Terry.

I still can't believe i sat here last night/this morning reading all 20 pages of this stuff. Great reading is all i can say. Now my head is running in this direction for a future project. In the process of collecting parts and information to convert an air cooled VW dragster back to fuel injection using the Megasquirt. That experience should get my feet wet enough to try it on a bike. Always something to learn if we keep our eyes and minds open.
