Putting a Metzeler 300/35 Tire on a LSC
by “Big Ed”
Two Techniques to Get a Metzler 300/35 Tire on an LSC A 280 to a 300/35R Metzler on an LSC can be done the expensive way, or the cheap way. I've run the cheap way since my first 280 wore out in 2007. CHEAP WAY - Step 1 - Buy 300 tire, mount it leave it off. Step 2 - Buy 132 tooth x 1 1/8 inch wide drive belt. Step 3 - Loosen the bottom 3 fender bolts. Step 4 - Remove sissy bar. Step 5 - Remove 4 side fender bolts (2 each side). Step 6 - Place  1/4" shim between frame mount and fender strut; re-install fender strut bolts with lock-tite. Step 7 - Tighten the bottom 3 fender bolts. Step 8 - Shim the sissy bar lower mounts 1/4" (or just cut legs off as shown in picture, which makes for quick removal if riding local) then tighten all bolts. Step 9 - Take hammer and flatten turn signal wire tubing (2006 & up) along inside fender. Step 10 - Install your new 300 with new belt slid to outer edge of pulley (so it doesn't rub tire). Before tightening axle, cock wheel back 4 mm on left side (this makes belt ride in place without it walking on the pulley and away from tire rub). Spin wheel and belt in travel direction to make sure belt stays in place while riding. Adjust more if necessary after completing a test ride. How you know you got it right is when backing bike up you can here belt noise.   EXPENSIVE WAY - Now the expensive way: Take your stock 1.5" pulley to a CNC shop and have them duplicate a 1-1/8" pulley with offset to the right (about 600 bucks). Install using above steps 1 thru 9. I've been riding the cheap way for 6 years; rode to Sturgis, Canada, Daytona, and many other trips logging over 18,000 miles. Bike tracks good, rides slightly better, and is super coooool! Like John Holmes said "bigger is better" Big Ed
