Waiting for the info on the fuel injectors from Injector Experts in Ohio. The owner is an older gent like me. Last piece of the puzzle at this time. Cleaning up the bike, securing wiring and such, thinking of next wiring upgrade, yes going to redo what has been done - using the "better mouse...

Have to keep the momentum going. After reading this information you may wonder why then, should a person think of changing one of the wonders of modern motorcycle technology. The main issue, is you cannot change the CFI system. You have to let it go on until it finally goes the way of the...

History of the CFI System. Don' think I posted this information before. It is from the Motorcycle Fuel Injection Handbook by Adam Wade. He discusses the different EFI system back in the 1980 to 1990 era. he saved the Honda CFI system for the last because of it was extremely unique and well...

For the number of times you will remove the header, the inexpensive off-shore exhaust gasket will work well. Just make sure that you remove all the old ones.

This EFI document I'm putting together is some 67 pages and growing. There is a lot of information to digest and more coming. Some is cursory, other more detailed, and then some very detailed, glossing over that which I do not feel is important at this time. The information I'm discussing is...

Tents are interesting in that the cost goes up as apparent quality goes up. Weight of tent is directly proportional as well, the lighter the tent, the more expense. Dome tent or a more squarish tent? Height of the tent is important if you are a tall person. Not all one person tents have the...

This information I'm posting is what I need to read and understand for this project. I will find more information regarding AE, but have to find out about "Tip In" as well. Still waiting on the fuel injectors, at shop for servicing.

Good YouTube video on acceleration enrichment (AE), the history of this and the challenges even today. Watched it last night on YouTube - Dr Jim Cowart - IC Engine and Transient Enrichments. . Good information regarding AE, specifically on initial start in the morning and after engine is at...

Thanks Joe. Have the EFI document well underway - some 65 pages or so to date. Waiting for the injectors to come back and the injector data with them. Watched a video last night on YouTube - Dr Jim Cowart - IC Engine and Transient Enrichments. God info all round. Particularly about...

More research done and this time regarding coils, spark units (coil drivers) and coil dwell time. It's interesting information, will probably be like school and past work where the information was required, but now, only if needed. Looked into the theory and practical issues. This...

The CFI FPR gets the vacuum from one source. It works fairly well. Been over 48 hours and the fuel system is holding at 7 PSI. Indicates to me that there should be no air in the fuel rail - fingers crossed. Prepping the bike for trials this week. Will connect the FPR to the vacuum mixing...

As mentioned, upgraded the fuel system, installed an aftermarket fuel pump that I had bought and used previously, new fuel filter, non-return valve, adjustable fuel pressure regulator, and fuel pressure gauge. The FPR is an inexpensive one but should do the job. I noticed on initial install...

This post is about the research I did regarding Spark Duration, also called Burn Time. Has to do with coil(s) - dwell time, spark plugs - burn time/spark plug electrode gap, and the distributor/electronic control units. Took me further down this rabbit hole such that I have included...

I find this very interesting. The more I understand about the EFI system, the more comfortable I am with this project. Need to understand what the various parameters are and how these are used by the ECU so that I can properly tune the engine. Just finished up the research on the Spark...

133 posts and still the bike is not on the road. There is a lot to be learned about this EFI world. Waiting on a set of injectors, sent out for cleaning, flow and leak testing as well as data about the injectors. Cleaning up small items, wiring placement and such. Have timed the engine...

Taking a trip down memory lane. Like reading previous articles I have started and the comments from other members. I have started a book, have 4-5 chapters done, need to revisit. My latest GW project is replacing the OEM ECU on my '85 FI model with a new aftermarket ECU. Have had it...

Researching an EFI system, how it operates and what you should be considering is always a learning experience. based on the premise that the fuel injection system is designed specifically to control the fuel delivery to the engine. Nothing more, nothing less. The CFI system does this by using...

Need a bit of assistance in reading the timing marks. It was very simple with the original ECU, set the timing belt and crankshaft marks to align everything to #1 TDC. Now reading the manual and notice that once this is done, you use the "F1" crankshaft mark to set the timing for idle. Can't...

Joe - we have the same view regarding FI, just a different way of expressing our thoughts. Still searching using the "oracle" (google) and finding out more information.

We are on the same page! Apologies for missing your point. Think we have covered everything possible. Cheers
