Yes that's what I'm saying.

However, because the wire is thicker, simply tinning the ends of your leads means you already have a greater area containing the more resistive solder. So even if your solder points are flawless, the greater area should mathematically yield greater resistance given both gauges of wire are soldered identically perfect.

If you really want to do it, you will more than likely be able to. its just a matter of deciding you are going to do it and apply yourself.

The most crucial element in painting lids like this is PROPER application of liquid. If you brush it on it is a thousand fold more difficult to cut your design than if you spray your liquid mask. On bodies this thin, it is imperative to have it sprayed on because you need the uniformity to KNOW when you've cut all the way through. With a brushed LM you will cut through most areas but will have to go back over some thicker portions and it can lead to overdoing it, leaving you with deeply scored portions that require little encouragement to snap/break. You can use a cheap $30 automotive spray gun from Harbor Freight to apply LM. Just lay down 3 solid coats all the way to the edges and allow to dry in between application. I use a blow drier to speed up the drying.

Quick question on the running a Bmax transmission. Do you need a custom battery brace, or can you use the Bmax one?

You need to use a different Battery Brace for a YZ-Max.
The BMax one is also too short, but some Aftermarket Manufacturers have already Released C/F Battery Braces specifically for it. Think MB Models Sell them!��

thicker wire = more resistance ?

your wrong buddy!

Is this incorrect?
Simply put, No it's not.

Larger wire provides more volume for power to flow. Look at resistance like water flowing. The larger the hose, the more water you can flow.

Good tip. I never would have thought to spray this stuff on. Do you thin it with anything first? Thanks.

Good advice indeed! I guess it mostly comes down to me being very lazy... Thanks for the tip on LM, though... Always found that to be kind of anoying when you don't make a nice cut the first time because of uneven LM.

You can thin LM with water if you like. I did ¼ water ¾ LM initially and it helps with dry time but in the end you might need a 4th coat.

If you spray it straight from the bottle 3 good coats will be perfect, BUT you must make it a priority to put enough on the sides. Use too little and you will be hating life as it will be very difficult to remove, especially once paint is overlying it. You also want a fresh X-acto blade to cut your design and make sure you look at the design and cut the outermost section first or you will end up with additional trim lines where you don't want them. Drop shadows are the most difficult thing to learn but it's all in how much thinner you use and it should be 85% thinner and 15% color so it flows out of the brush with almost no pressure.

But what happens if you install a Brita in that pipe??

Precisely what I'm saying about solder in the mix.

Solder's conductivity is less that that of Copper & Silver wire, hence my questioning if what I was taught was correct or not.

A bad solder joint hurts the connection, but the bigger wire and the resulting bigger solder mess still has lower impedance than the equivalent with smaller wire and solder mess. Assuming equal mess vs size.

If you can't solder, you'll have a harder time on bigger wire though, so it's still sensible to stick with smaller wire in that case. Plus, diminishing returns and all that vs. cost and weight and soldering difficulty.

So when's Randy Pike going to post a pic of his YZ-2 with the 3 gear we saw at Reedy. Looks like they went back to the 4 gear BMax tranny chasing a bit more forward bite.

I just scooped up a bmaxx to try the transmission out..
Question about the yz-2 I see there is a shim kit to get the trans up higher, how much does this help also was thinking if I shim the trans higher why not clock the motor mount??
