I'm betting this is on here somewhere, but the search isn't showing me.

I need to lower the front end to balance out the bike after I lower the back end.
Is it as simple as loosening the bolts on the upper triple tree and then pushing it down or do I need to loosen the lower triple tree as well?
I'm simply lowering it because I am so short, not for any performance advantages (I love the bike as is).

Yes, you need to loosen the lower bolts as well. I find it easiest to loosen the lower bolts fully then gradually back off the upper bolts to the point where you can carefully tap the top yoke with a rubber hammer and the forks come through a bit more with each blow in a controlled manner. Don’t lower the front too much or the lower fork legs and fork seals will contact with the bottom of the bottom yoke when you hit big bumps.

OK. Forgive me for not knowing, but are the two triple trees connected by a bar of some kind? Something other than the forks themselves? I've never paid attention in the past and I can't see it through the faring.

OK, I went out and looked closer and now I feel like a rube for not realizing it. Thanks for the lesson. :)

Not sure how much you are planning to lower it but be aware that if you pull the forks up more than about 15mm from the stock position the fork lowers can bottom out on the lower triple clamp.

Thanks for the heads up. I was going to lower the rear about an inch and wanted to level it out. I am a small guy (I weighed 105 yesterday) so I'll see if I have any issues bottoming out.

Finally got the bike dropped down yesterday (took way longer than expected). The dog bones took forever as the grease on the sleeves was like glue, but once they were out, the installation went quick. The kickstand was a total pain as the replacement I bought was not where near a direct bolt on as listed. Fortunately, my Dad is a retired engineer and a bunch of grinding, drilling and tapping got it installed. Front forks were a quick job. Rode it home and never bottomed out and the bike was still nice and balanced.

Nice...got any pics?...

Looking to do this later in the week...so is there 2 bolts at the bottom and 2 up top??? or is there another bolt that needs to be loosened.

I'll get some pics.
Yes, two at the top on each side and two on the bottom on each.
I totally loosened the bottom four and then tried to only loosen the top ones enough to move it, but I over shot and ended up needing to jack up the bike to get it right. No big deal, but a pain.

I dropped the bike by about 1.5". And yes, loosen the top bolts just enough so they are still snug and then push down on the bars until they get to the right spot.

And then you drive a big ‘ol truck that looks like you need a ladder to climb into. 😂
