lighting circut guru needed please help!!!!!!!

all right let me begin i've installed piaa 510 series lights on my z there 35 watt h3 bulb each light so here's were it gets confusing it came with its own relay harness i would like my low beam circut to run one lamp out side the piaa harness and the high beam circut to run both lamps via the piaa harness with the high beem circut as the swith for the piaa relay so how do i wirre both power sources (high beam and lowbeam) to one lamp and not have the low beam travel back to the piaa harness and activate the relay ?:thumbsup::moon: :moon: :ride: :ride: :p

The problem - All right, let me begin. I've installed Piaa 510 series lights on my Z. They are 35 watt H3 bulb each light. So here's were it gets confusing. It came with its own relay harness. I would like my low beam circuit to run one lamp out side the Piaa harness and the high beam circuit to run both lamps via the Piaa harness with the high beam circuit as the switch for the Piaa relay. So how do I wire both power sources (high beam and low beam) to one lamp and not have the low beam travel back to the Piaa harness and activate the relay?

The solution - I assume 1 relay with a siamese terminal to power both Piaa lights, (parallel connection). Activating the relay is not a problem, relay control is a separate circuit. The problem is not powering both Piaa lights via the parallel connection. All you need is a diode. Power 1 of the Piaa lights direct from low beam power. Put a diode in the wire from that Piaa light to the relay. Face the diode so it blocks low beam power going to the relay. (You need a diode of 40 volts or higher and 5 amps or higher) However, now you will power everything connected to the low beam circuit with Hi beam activation. If that is a problem, there are other ways. Probably 2 or more relays.

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!

      -Oil / filter changed every 1500 miles
      -New did chain , brake pads , front sprocket at 10400 miles .
      - valves checked and within spec at 10,000
      - jetted with JD kit and 3x3 mod
      -doubletake mirrors
      -waterproof usb wired and located next to Speedo
      - drc large foot pegs , barkbusters with integrated turn signals . 12oclocklabs tall delete with upgraded circuit board

      Currently have a 2000 drz400s work stock suspension. From my understanding this is the worst suspension the drz ever came with without even rebound damping adjustment. Therefore I'm looking for a upgrade. I'm seeing three approaches to take. First being a newer year s model suspension with dampening adjustment. A SM model USD forks and triple tree or some USD forks and triple tree from a rmz. So if you were going to upgrade what direction would you go. I currently ride off-road mostly but I do have some 17s for on road with as well so have to keep that in mind. Thanks
