Yeah you're right, aircraft just a cruise rpm and keep it there, so fuel system doesn't have to be on the fly like a road vehicles fuel system, constantly on and off the throttle. LoL I always like to think outside the box. I was looking online and it seems there are a few EFI options out...

Same, Statefarm 27 M1 very clean drivers abstract. Pay 1200 a year.

When you had apart you checked the float height and needle and seat? Could be the jet needle is not seating properly with the main jet causing it to draw to much fuel? Pilot jet in the idle air circuit could be backed out to much causing it to draw to much fuel. Choke plunger stuck causing the...

I have been toying around with the idea of a mechanic fuel injection system for my bike as well, thinking of ways that I could do it. Here is what my basic idea was, I'm sure that it could be adapted for an electrical though. Components: 1. Throttle body 2. Two Fuel Nozzles with manifold 3...

I think you made the right move, aircraft maintenance is a shit game lol. Yeah that chamber appearently has little semi valve set up with these little bleed holes (from what I read online) and they can get clogged preventing the chamber from mixing that A/F mixture. I should check if mine are...

Yeah you got to love replacement stuff like that. Breaker points can be a pain without proper equipment to time them, however I wish my bike had a breaker point ignition because its something you can repair without having to replacement boxes etc, because with the ignition I have you can't...

LED lights are a pain with these old relays. I ended up throwing some resistors in line with with the leds to draw the same load as the original lights. Still flash a little faster then normal but I didnt know about these LED relays. Thats useful to know now thanks!

Thanks for the input. I always forget about that YICS because the little emblems are missing and I can't find replacements! The YICS ibtroduces more issues in the tuning because I don't know if they may be blocked. I was able to syn. The engine up (fairly decent) without blocking them so...

Yeah it could benefit from the spark advance, unfortunately its not an easy adjustment as you said the mounting holes would need to be elongated. I want to play around with hooking up EGT probes on the exhausts and record the data of the EGTs and see what type of temps I am getting vs. RPM...

Wow thats great looking, and how can you beat that price! I really like the fiberglass work on the seat you did with that light as well. Shame that the paint didn't hold up for you, I am having the same problem on mine, another repaint I am dreading. Do you have plans to do anything with the...

Suggesting maybe milling the head? Is the engine interference fit?

Hey Dave, great to know that there are others in the area and I definitely will take you up on the coffee offer. My father in law and I (the FZR400 in the pictures you see) took a wicked ride down to Port Dover and a long the coast through Long Point - great summer ride. Thanks for the tip...

Hello Everyone, long time no post, however I didn't want to post until I had a bike to actually contribute some information and pictures with. So my bike is a 1984 Yamaha XS400 Seca, my wife and in laws bought it for me for my birthday last year in 2015. Over the winter I had worked on it, and...

Hey Guys hows it going. Yesterday I came home and lately I have been noticing a weird click in the back end of the bike. Upon further inspection I found that if I rotated the tire, at a certain point it was binding up. The chain is going super loose and super tight. I pulled off the drive...

Hey Tim welcome, Sounds like the needle in the float for the carb is not seating properly. In the PRI position fuel is able to free flow to fill the bowl for prime, in the ON position it uses suction in the intake manifold(boot) to pull on a diaphragm inside the fuel selector valve. If let on...

Hey thanks for your replies I got it figured out, I was having some intermittent spark issues with the cut off relay. That has been fixed, carbs cleaned and synced and it starts beautifully now. You guys asked for pictures here you go she is 90% complete, needs some more compounding and buffing...

I have a Seca 400 but I cannot figure out the method to start it, this thing keeps back firing with no real attempt to go. Any thoughts? I have started it before.

The Seca has a cutoff relay under the seat, not sure if the 81 is the same but mine had an issue where is was grounding out through that relay. Unplugged the relay and it now functions so I am wondering if you might have the same thing which is grounding your ignition.

Been working on my SECA build, got the tail section completely finished, and frame repainted in gloss black. Painted the forks, and cleaned/serviced/ and painted the brake caliper. I turned on a lathe a plug to remove the cable tach in favour for an electric on. You will see the finished...

I'm not in your area but with pictures and schematics I'm sure that I can help you require your new fuse panel! Send me a PM.
