Now this is the type of stuff I like to read about!! Definatly got me thinking of doing late model EFI on my 1978 CB750 for sure. Looking forward on how you do fuel delivery and engine managment. Im thinking of the basic MAP sensor, Oxygen sensor, Water temp. you doing a IAC? Basically, what basic sensors you plan on using to control the fuel management process of the motor?

I love this Stuff!!! You really got my mind thinking of endless possibilities with modern EFI use.

Love the out of the box stuff.

I'll be using the MicroSquirt ECU and '08 600RR throttle bodies. You can pick them up for less than $50 on eBay. I will be using the IAC that comes on the throttle bodies and I also have the IAT from the 600RR that I will be using. I plan to run in closed loop so I won't have a MAF. For oxygen sensors I will just use standard o2 sensors but I have a wideband setup for tuning. There is no water temp since my motor is air cooled but I will be installing a sensor to monitor the head temp and probably oil temp. As for fuel delivery I also have a stock 600RR fuel pump that I will install in a custom built tank that fits under the seat in the triangle portion of the frame. I am also adapting the 600RR stator and rotor so that my charging system can handle all the new electrical demands.

What are you using for pistons in the 65mm bore, are they stock Honda CB750?

The pistons are from Wiseco and made for the 750 big bore setup. They are larger than the standard 750 bore which I think is 62mm but I'm not sure.

I hope my engine builder has the chambers done and valves built for the head by the time I get home in a couple of weeks. I would like to get the engine together and on a stand so that I can play with the EFI prior to putting it all into the frame.

Very cool. I am sure you know this, but you're going to want the R/R from the new bike, too.

Yep I've already got it. I actually have the whole wiring harness so that I would have all the correct plugs. I just have to integrate it with the MicroSquirt and I should be good to go.

Gday Chevelle, you back home..? Hopefully you are . I have my GSXR throttle bodies all set up now, i'll post a pic for you if you are interested, good to see you posting again....

I'm not home yet. I should land in GA around the 1st so just under 2 weeks to go. When I get home I still have to get my new shop in order. I moved all of my stuff into this building just before I headed here so nothing is set up, its just all stored right now. I will be building another 30X60 building to house all my vehicles and then I can arrange my current building so that I can actually do some work. I still have to run air lines, upgrade the 208 service to 200amps and put my epoxy floor coating down. So all that being said I will tinker with my bike some but I will mostly be working on getting the shop setup. I hope to get it all done in a couple of months. I've got a ton of projects that I need to get started!

Sounds like you've been spying on my place. no new shops but always something else to slow the process down....

I'm over in Americus. It's about 3 hours west of Savannah. If you take HWY 280 it runs straight through my town. I can't wait to get home so I can make some progress! 2.5 years in Afghanistan was enough for me. I'm ready to leave!

Wow 2.5 years! I imagine you're ready to come back to to the good old boys of Georgia. When you're back we'll have to go riding sometime! Take care. Thanks for serving

I would love to ride over to Savannah sometime. I'm not in the service here, I'm just a civilian working here to support the military. As they downsize bases are closing so its a good time for me to leave. I certainly am ready to be home!

Looks wicked ! Looking forward to see The progress !

Here you go Chevelle, some inspiration...

Ah man I'm jealous. Those look great. Nice work on the fuel rail.

Nothing to do with my bike build but I had a chance to snap this photo today so I thought I would share.

I would think the fully encased chain would be very worthwhile in someplace that dusty

Godffery · « **Reply #69 on:** July 26, 2013, 08:13:13 PM »

Very ambitious project, Very impressed with the results so far!
Looking forward to seeing what you do with the chassis & body.

Thanks. I like challenging projects. In addition to the bike I'm also working on putting a 05 Duramax and Allison trans in a 52 GMC 1 ton truck to be my shop truck / parts chaser. I am also working on dropping a turbo Ecotec engine in my 1966 Datsun Roadster. As you can see I like EFI and I enjoy the challenges these projects require. It pushes the boundaries of my knowledge so it's a great way to learn.

SICK

my favorite body style of old GM trucks. I wish I could afford one in nice original shape. Followed by 67-72 of course
