If I go with Sonic front springs .90kg/mm, what weight fork oil should I use? I'm 5'-9" and 165 lbs.
10w would be fine for you.
I agree with the 10w oil. :encouragement:
Are you putting Cartridge emulators in as well?
Cartridge emulators? I don?t even know what that is. Please tell me more about them. It sounds like something else I need to spend money on. Lol.
I don't know if it's because I'm an insensitive lout or what, but when I installed emulators on my bike, I could not really tell much of a difference.
I keep hearing how much better the suspension is with them, and I can appreciate the fact that they are adjustable, but I did not notice much.
To keep things fair, I believe that most who install them are going from a clapped-out system that is not working well to one that does, and that is impressive, indeed. However, I rebuilt my forks with Sonic springs and fresh 10w oil, then did a 1000-mile weekend at the Brown County rally. One of the roads made me think that it was a test track for a suspension company. Potholes, patches and repaired potholes aplenty. You could not go 100 yards in a straight line without hitting something. The ride quality was worthy of a Cadillac.
A month or three later, I installed the emulators. I made no adjustments to them before installation, heeding the advice on some other forums. There was no "night and day" difference. In fact, I thought it was not quite as good, so I took them out, verified that they were adjusted properly (they weren't) and put them back in. After the adjustment they seemed to improve back to what they were before installation.
Another factor is cost. The emulators themselves are not exactly pocket change, but are not that expensive, either. In my case, they also required some adapters for larger-diameter forks. I don't know how readily available they are, but a member here offered some prototypes for testing (thanks, Dan :encouragement

. I am sure that if something like that was commercially available, they could cost almost as much as the emulators.
Bottom line (for me): if you are really sensitive to your suspension's operation, possibly you are one who can tell the difference between 10w and 8w oil, they might make a difference. On a race track, they might make a difference. But, for me and the way I ride,

I just need to wire up my lazer detector. The road is infested with police.
I have used radar and laser detectors in virtually all of my vehicles since about 1975. I have not always had the top of the line, but have stuck with the better ones. Radar detectors have changed over the years, and so has radar itself. Radar does not necessarily give a reading on the closest or the fastest vehicle, it gives a reading on the best reflector in its beam. Early radar units (x-band) had a six-lane spread at 100 yards. It was up to the operator to determine which vehicle was the offender. Later k-band units were tighter, only covering two or three lanes at 100 yards, but there is still uncertainty. Depending on the terrain, a radar beam can easily go for over a mile, meaning that the spread actually covers both sides of the highway. If there is a motorcycle 1/2 mile away and a semi a full mile away, which is the better reflector? If the truck is the one speeding, who gets the ticket? Most likely, it will be the one that the officer sees first.
Laser units have aiming sights on them. They are accurate enough that the officer can aim at a motorcycle between two semi-trucks and get an accurate reading. If you get an alert on your radar detector, you only know that you were in the beam, but because the beam is so wide, there is no guarantee that YOU were the target. The police laser unit is so focused, it can be aimed at a vehicle in the lane next to you and your detector will not alert you. If your laser detector alerts you, you should know that is merely an alert that you have been caught, so go ahead and pull over, if you have been speeding.
A couple other things to consider:
1. At one time (many years ago), radar detectors were not allowed in Canadia. Not sure if laser detectors were included and I don't know if that might have changed. If they are not allowed, be aware that there are not many places to hide one on a motorcycle.
2. How are you going to receive the alert? Even on my Goldwing, the alert was not enough to attract my attention. You will need to route the audio into your helmet or have a very bright light.
I have since adopted the philosophy that my bikes are not race bikes. Yes, there are times I hustle along a bit above the posted limit, but not at speeds that would likely attract attention. I have removed the detectors from my bikes, but still keep one in my car.
Lastly, keep in mind, "it's not how fast you drive, it's how you drive fast".
