57mm
Pwk 28
32 pj
110mj

Tried pj from30 to 38 and mj 105 110 115 .. 30pj 105mj is crazy acceleration but sparkplug reading shows very lean.
Same setup here.. mine is 35pj and 110mj.. but, installed 105mj recently. Haven't tested its performance yet.

Anyway, what's your experience with 105mj in terms of top speed when compared against 110mj?
 
Stock bore, 5.7cams, stock valves, rcdi, lightened magneto, 15-42 sprockets

SWR roundslide:
115-35 jettings


What size of jettings can do for touring?
Thank you.

Hi to all fellow bikers.
I recently bought a LC135 V1.
Did some modification to it but having a headache now with the tuning of my carburetor.
Can help give some advice?

Current set up
Cylinder head stock with racing valve springs and cam.
57mm FZ150 block
Carburetor NSR 28 with cone air filter (air box) removed.
My jetting now is mj100 and pj 32.
But running quite lean when I checked plug.
Previously tried 108, cannot go more than 90km (meter) and heavy bogging.
When try mj105, can go up to 110km before the bike start to bog.
Any advice from all the seniors?

I think the problem is your pilot jet, try using a bigger size. Remember that the pilot jet is controlling the idle to 1/4 throttle.

maybe still lean. try increasing your mainjet and pilot a little more. have you tried to tweak the af mixture?
