Well...........actually I wish I had been part of building this one, or the one I would own, but that did not happen.
So it is 42 years old, what, wow it is that old since it was first licensed for the street here in NV.
I never had an area for such work, have some room now, but still not all that is needed, so if I want to have something it has to be something I can work with, so far this I can, just wish I had more of my garage so the body could sit inside when I take it off..
I did the stupid thing, got a low priced pressure gauge and the tolerance on it is to much for the low fuel pressure I want to monitor. I say it is 1 or more psi off, but than the spring loaded diaphragm regulator may be off.
I did a few test, went with the setting of 2.5 on the regulator which shows 1lb psi on the gauge, and the engine idles smoother. If I drop the regulator down to 2lb setting the engine idles a bit rougher after a bit of time, and the pressure gauge drops almost that 1lb psi reading it has at 2.5 regulator setting.
Off with the air filter so I could look down the throat of the carb, no wetness or sign of excessive fuel, so I it makes me think that the spring in the regulator a bit worn.
Next real test is down the road under load to see if the fuel system is supplying what the carb's demand.
Sometimes I can be stubborn to much for my own good, but I do like the trike and I do think I can fix what is wrong, maybe not by my hands all the way, but it can be done I am sure.
I just wish I new more about bugs and the IRS rear end history. I do wonder if these trailing arms have been abused and are bent and why the camber is so negative, but I have been adjusting the torsion and spring plates slowly, plus need to do both sides, than move it and bunch it around, look over things, and lets not forget raise the forks to the positon I want the front end in.
It for sure is giving me something to do, LOL
