I have taken the Superlight out a couple of times now. It feels like it is just kind of bogging down around 70 or so. I can have the throttle wide open and that is all there is. I live in north of SF and wonder if it is jetted wrong. I am not a carb person. I can tear everything apart and put it back together but a good tuner I am not. It has FCR 41's on it. How do I get it to you and back and kind of give me an estimate on tuning price please. # 505 220 one 70 one.

Sorry for the delay.

Tuning is "seat of the pants" for anyone without a dyno, so it's trial and error and can consume a considerable amount of time.  My SS had FCRs on it when I moved here and I remember having to lean it considerably to make it run close to right, so if you're on the "stock" jetting (as delivered by Sudco or California Cycleworks or whomever) it's probably quite rich.  The tuning procedure for these without a dyno is basically do a bit of research, set what you think it might be, then tune top end first with the main jets, idle and off-idle with the low speed circuit, then midrange with needles.  Changing jets once is a couple hours' work.  Changing them 10 times or more until it feels right is a whole other animal....though it's generally not more than three or four times to get close.

I'll chat with Stuart and see if we can come up with an estimate.

PJ's is definitely still in business.  505.323.6700  I'm pretty sure I don't have a pressure switch for an '01, but I'll look and get back to ya.

I am going to the local auto store to see if I can source a pressure switch. There is one for a opel that works. I guess the phones at PJ's were not working yesterday.  [bang] I would really like to get the Superlight performing well. It is fun to ride now that I have sort a few things out but it is not running to its potential.

Well...  I do have a used one from an '07 M695 if you're interested in that...

Well the 93 Superlight is up and running. Now the big problem is the 01 SS. I had some knocking and I thought it was a hung up valve. I pulled the heads and in the vertical cylinder I pulled the cylinder. the rod was never tightened down. It only has 5000 miles on it. I think I am looking for a 1000 or an 1100 motor now unless you guys have a better thought than that. I would need new cylinders, rods, and crank at this point. Let me know your thoughts.

To swap to a 1000 or 1100 motor, you'll need the following in ADDITION to the motor:
SS1000i.e. Exhaust header
1000 intake manifolds
1000 throttle bodies unless you get a 1000 ecu which doesn't require the throttle body stepper motor (if you run a 5.9 ecu)
A 1000 or 1100 5.9ecu DP ecu (preferrably)

Cans will swap and motor mount bolts too.

Just be sure to get a Monster or a Sport-Classic engine as the Multi & Hyper motora have the narrow swingarm pivot.
