DBM, My bike is converted into sort-of a solo bagger. Homemade seat sprung off the top shock mounts, a box/backrest where the rear seat was, big windshield, saddlebags made from .50 cal ammo cans(and a lot of fiberglass), tubeless wheels off a 02' Marauder, GPS speedometer, 4.5 gallon tank from a Yamaha V-Star, and front & rear Kaw drive pulleys, Daymaker LED headlight, and a bunch of LEDs made into a light bar on the back.(it's a ulgy thing for a tailight, but here in Fla. people have a hard time seeing a semi, so the more lights on the back the better!)
I travel on it a lot, best trip was Salt Lake City in 18' (was at opening day of Speedweek on the salt flats,,,VERRRRRRY COOL, for 105 degrees) Up to Western NY where I grew-up and back, and a trip or two every summer to see Moe at the KSL in western N.C.
(DON'T LAUGH) I also go to a LOT of Roller Derby bouts and tournaments all over the southeast and mid-west. That has been put on HOLD for the last 2 years cause of Covid.
This is a link to a post from Oct about the front brake and tubeless wheel conversion.

Both have been covered before by others in more detail. I belive Dave was the first to go with the dual piston caliper from a sv650.

OK Gary.  Thanks for the advice.  I will add some oil and see what happens.  BTW, my current oil level is 180mm, not 120mm.  I will try 170mm and possibly 160mm.  Progressive cautions against going higher than 150mm.  I think I will shoot for 85 to 90% over my current braking test surface which is a pretty darned rough section of poorly repaired pavement.

Dave, thanks for the info on the SV caliper and the link to the Big Brake kit.  It looks like a nice setup.

DBM, The back wheel is the mate to the front, a 15x3.5 tubeless.(front is 16x3.0) Drum on the back.
I lean back all the time, don't know how I rode so many miles without it.
I run Shell Rotella T4 dino 15-40, changed the cam chain at 80k(but the follower was the real wear part there, have since removed the tenisoner pawl spring, turned the plunger upside-down and shimed it to 1.5mm movement and no more plunger extension for the last 20k)
Ran Shinko 230's either 150 or latley 140/90-15's and got about 15 to 18k on them but got a good deal on a Mich. Commander 2 140/90 15, currently 6k and showing very little wear so far, but seems worse in the rain.
Had the head plug leak and lower head bolt leak.(who hasn't?)
Some clutch slippage so I put a extra steel plate in it to cure that.
132k on it now and plan to look inside the left side case again at 150.
I have a new cc follower to put in then and I think the cc will go to 200k with the pawl out of the picture.
