Q: why the relay before the starter solenoid?  The sloenoid is a heavy duty relay.  You should not need a second one there.  Use it instead just for the coils.

well, because it was suggested to me and I have the room for it. the wires for my starter button are tiny, like 22 awg or something.

O2 sensors: It seems counter intuitive, but when the bike is running we know we can feel the pressure of exhaust coming out but what we don't feel is the fresh air pulsing back in.  That's why short pipes show up as lean on the Lambda sensor and that's not accurate. 

On one two stroke we tested on the dyno with a sniffer only part way into the tail pipe - it read lean even when it was clearly too rich.  Mechanical baffles got in the way.

the exhaust will be pretty long - longer than scrambler exhaust - as it will go down around bottom of frame and up to the rear swingarm

Starter solenoid only needs couple hundred milliamps to operate, your powering a coil to operate main contactor, plus, it isn't a 'constant on' component (should be max ten second 'burst')

Most Honda solenoids will pull over three amps. It's not a trivial amount of current and I recommend 18 gauge wire or thicker.

the old wiring I had used 16awg wire directly to the sol and never had any issues - this time I am using a metri-pack box that can house 4 fuses or 2 and a micro relay, super tiny 20amp relay and the button uses really small wires - the manufacture "requires" the use of a relay with this button.


BTW - i ordered from vintage connections - thanks for sending me spare little contacts in the connector sets.... that's a step above and much help!!

On the primary windings?
It's one of the few parts I don't remember taking measurements on ;D

Yeah. I just ran one on my power supply. 3.18A at 14.2V. It was from a CX500.

Because of truck issue I've been looking up O2 sensors. (you forget a lot of stuff when your not 'using' it  ;) )
This is the best video I've seen explaining how they work and what they do


BTW,. you only need to watch about first 30 mins, the rest is on actual vehicles so pretty worthless to 'us'

ran into sort of a problem and have been held up a few days - I seam to have misplaced the shim (thrust washer b) needed for the camshaft end play (part number 90484-369-000)

I am not sure if it slipped in between the cracks in my work bench but it's LOST FOREVER

problem is... everywhere I see that - well the only way to get one is to reuse the one you have.

in other news I got my head back from the shop, oversized 1mm intake and a mildly ported (match port, D shaped exhaust and matched intake boots, small sculpting done to the intake and exhaust around the valve guides and smoothed area at the seats

getting excited to get this thing together

oh, and while I was searching for the thrust washer I keep coming across a "sealing washer" (like this one) and I have no idea what it is where it goes

If you have the specs, I'm pretty sure most washers would work.
