    Best non-BBK power mods?

    You can also reduce power loss in the drive train. I had positive results when I changed out my old chain and sprockets to lightened sprockets and a Renthal non-sealed chain. A claim I heard about and tried was to remove the snorkel off the air box. A fellow on this forum said he dyno'd a half...

    Synthetic oil

    I've used that very oil too. It works well for long wide open runs. After a big bore kit install, I switched to Amsoil 15w50. I am still pondering the use of 20w40 as it claims better thermal break down resistance in general. I also have some Rotella 15w40 sitting around🤔

    Winter Riding in the Midwest & Mods

    How does that leg windshield attach? Can you post pictures? It seems like a very cost effective mod.

    Tires Megathread

    Are the Super Cub wheels interchangeable with the Trail 125? I'm pondering the usefulness of tubeless tires for the street. I can buy a front and rear wheel for around $700. I believe the super cub still uses drum brakes in the rear...

    Out in the Elements

    Perhaps upgrade the chain to a sealed type? I also know there are products out there that spray on to prevent rust. I can't say I have ever tried them though. There may be stainless steel bolts and nuts out there that you could upgrade to with anti seize on the threads.

    Changed my rear sprocket out for better RPMs at high speeds

    I went one up one tooth on my front sprocket since I have a similar use. I lost some top speed as well, but smoothed out the bike vibrations. It maxed out at about 50 MPH. I then compensated by adding power mods. Now it can cruise at 60 MPH. I have not had an issue with the ABS. I recommend a...
