Any Ways to Reduce Friction Roller Slip?

    I took my Bike Motor Parts unit out tonight and and it ran pretty well for a first ride. I have a 43 cc Kawasaki two cycle engine.

    The only think was it had just been raining hard and the wet tyre made that roller slip a lot.

    Does anyone have any tips for reducing roller slip? I am thinking of soldering some blobs of solder on the roller to give it a little more grip.

    I've owned several friction drive bikes. I also have two BMP friction drives.

    What size roller do you have, 1" or 1.25"?

    My best advice would be to ride only when the road is dry...or live with the slipping and sliding and pedal along with the engine.

    I commute to work whether it's rain or shine. On the few times it was raining, I simply pedal along and use less throttle.

    Riding an MB with slipping roller in the rain is the pits!:sweatdrop:

    But it SURE beats pedalling a regular bike in the rain!:jester:

    mine too

    mine too
    slips like crazy when wet
    have to really put a lot of down pressure on that THING when wet outside
    all of that down pressure
    sure does slow my little thing down
    and can't be good for moving parts

    but it's what I have to do in the rain to ride that THING

    CRC makes an excellent fan belt dressing, CRC Belt Conditioner. Try cleaning roller,
    and giving roller a shot of it to increase friction. Over the years, I've used many fan belt dressings, the CRC is the best.

    I've been thinking about coating a roller with plasti dip
    and maybe adding some grit to it before it dries.
    Has anyone tried this??????

    Road surface abrasion would wear it away in no time.

    Oh heck yes, in just about every configuration one can think of from Pliobond to harder wearing epoxies and aquarium sand. My take is hardly worth the trouble for traction but it can serve to build up worn spindles. What the heck though, give it a try, lots on this in the archives here if you do a search, btw.

    There are drawbacks in every drive systems, riding in the wet is the major one for FD.

    I live in a wet climate and have resorted to merely listening for when the motor races higher than what is normal for that speed, then backing off on the throttle. Nothing you can do otherwise, as far as adding some magic goop or what have you, will keep you from slipping on a friction drive setup on wet streets. I expect about a 30% decrease in speed when it's wet. That's just how it is.

    [EDIT] Be careful about adding too much downward pressure on the friction drive setup. I was blowing out mount screws left and right for awhile until I reduced my 85psi tires to 65psi. Not fun losing one of those screws during a ride.
