This is the connector that comes attached to the cigarette socket.

2) And this?



This one is attached to the USB port.

I suspect that forum member Cheesy knows the answer. I recommend that you send him a PM.

That hadn't occurred to me, but it makes perfect sense that a Schrader would only be capable of 100psi or so. A quick search has not revealed the actual tolerance of a typical Schrader, but I have found several warnings against using a Schrader in a high-pressure application, like a shock.

Bend it down.... it's the tag sticking out beside the word "UP"
on the cable seat....

Nice job, eagle eyes!

It took a lot of washers, but I got the spring on.

Stumbled across this Dyno test result for the Rx3 EFI engine
Thought it might be of interest to some.

[jimjr21]

25.6hp @ 8994 rpm
This is a brake dyno of some type. Easy to tell by the rpm time trace. Engine is at maximum rpm then is pulled down to lower rpm over 6 seconds. These types of dyno's are hard on engines.

Indeed, it is of interest to me. Thanks for sharing the data, Kat.

I just got back from a 60-mile ride to test the shock preload adjustment I performed on my RX3. The ride contained interstate, secondary, and tertiary paved roads, including city streets. I also rode dirt and gravel roads. Tightening the spring preload adjustment on the shock absorber a mere three turns resulted in a very significant improvement in shock performance.

The shock absorber is still reacting a little too soft for my taste, so I am going to tighten the spring preload another three turns.

The WPS Li-On battery arrived today. It went into the bike with no issues. It weighs 2.4lbs, but it sure feels lighter than that. The bike fired right up.




I installed the instrument panel power outlets the other day. It was a fairly straightforward process. I removed the windshield for better access. The wings came off easily, and the outlets went back in just as easy. I was a little stumped as to where the power box goes. (I can't remember the proper nomenclature!) A quick call to Steve answered the question. It goes behind the right rear panel. Removing the plate under the pillion seat is the easiest way to access the connector. I will plug things in later tonight and see how they work. The windscreen was a little fiddly to put back on.

The battery looks great, as do the power outlets.

I think it is easier to install the windshield if you install the lowest bolts first. If necessary, install the windshield loosely before you install the headlight. Then it will be much easier to tighten the lowest bolts on the windshield.

I wasn't able to get my fingers behind the windshield to hold the nut, so I used a pair of needle nose pliers to hold the nut and then got the bolt started finger tight.

When I got the new battery in, I started the engine for about 30 seconds. The oil in the sight glass went away, as expected. It's been 4 hours and nothing has drained back to the case. Did I do something wrong when I did the oil change? No leaks noted. I'll check again in the morning.

Thanks for posting the good tip.

I made the mistake of installing the lowest bolts last, instead of first. I couldn't use needle nose pliers, or even a pair of tweezers to hold the nuts. Therefore, I had to resort to using a telescoping magnet to hold the nuts to get them started.
