I gallon of gasoline and a match.... I tried a couple different brake pads and didn't see a whole lot of change for the better. Braking for me was always a challenge requiring both front and rear brake use to scrub off speed. My laps times dropped substantially when I swapped to the cr80 front end with a disc brake...
You can play around with longer brake arms, more agressive pad compounds, matching the pads to the drums (radiusing?) and venting the drums... Or slap a disc brake front on.
Our rules don't allow front end swaps. We have to run stock. I was going to media blast the drum this winter in hopes that it might grab a bit better. I wonder if one of those hydrolic clutch kits for a pitbike might help with lever pull.
do the courses you run really require that much braking? Mine work ok for a few laps... then I have tot rely on the engine and the tire side to do the braking. Of course the bike complains with lots of chatter...lol.
There are two turns that are 3rd gear. They are off of 5th gear straights. I have been using tons of rear brake but the biggest thing is my daughter rides the same bike and I would like to lower the pull force on the front for her. She doesn't like using rear brake, but she charges the turns pretty hard. That is why I was thinking one of those hydro clutch kits might work. Some thing like this. http://www.pccmotor.com/hydraulic-clutch-lever-master-cylinder-pit-dirt-bike-mx.html
Yeah. I gave been pushing for them to change the rules. We can swap if we run the formula class, but I am trying to stay in the spec class.
You might have success turning the drums to make the round and square, then checking shoe alignment. I was thinking the same thing recently as I couldn't stop mine in the parking lot, and I had to take a solid run to slide the tire (to impress my friends, of course). It was less than impressive. If you can break the wheel apart and send the drum out, that might be your best option right now. Then look at those easy-pull clutch levers, they might make one you can modify to the front brake. you can also run the lever closer to the bar to allow her smaller hand more leverage closer to the grip. Or tell her to "man up."
She mans up pretty good. She rode with massive blisters on her hand for a whole weekend before she told me because she didn't want to miss any races. Not bad for a 13 year old girl that had never been on a motorcycle until the first race.
i changed my brake shoes to these before ridding it on track but everybody else who has rode the bike says these are much better then stock http://www.rockymountainatvmc.com/p/44/54/208/908/510/4479/EBC-Brake-Shoe-Carbon also vesrah makes some but iv never tried them there is also the terminator brake cable at the bottom of this pagehttp://www.xr100.com/crfxr100.htm i don't have one but maybe it would help with the lever pull
i've used the vesrah shoes , an improvement but the brakes still sucked i disassembled the whole system and made sure it was as good as could be , helped a touch more kinda half the fun of em though , having lousy brakes if it had killer brakes then it would need more motor ,then the chassis , soon it would'nt really be an xr100 anymore
