well, its' hard as hell to type when short a finger, but anyway... whit ho idea where to start, i'll break into the abckground and keep the story in sync with the pics at the bottom
To start with one of my other loves in life is stunting motorcycles (big and small) Well, on our small ones we've been teeming up with the JDRF and ACS for their children summer camps (imagine being at a camp where you're surrounded by a hundred or more 5 - 10 year old kids that hafve already lost limbs and such to diabetes and cancer but still can smile, enjoy themselves and feel really special when people like me and my team (mostly founded by me and a brother masonic lodge member..the other 5 on the team are just our good friends)
But anyway... For years we've been stuning these bikes that started as 2.5hp honda 50cc trail bikes and the new CRF50f, we nmodify them with bog bore kits( between 8 to 24 horses depending on your wallet), strteet tires, heavy duty springs and suspension bushings ans the addition of some stungint goodies like pegs, hand brake for the rear when you're in awheely with your feet over the bars or just not near the pegs and the all important BMX bar swap to get your knees out of your ears
Well today i was at a friends house and noticed a rare and expensice hydraulic brake system used on very high end mountain bikes and can only be had for our minis if you buy a company called "sano's" entire front end forks called the "sano bombshells" I remeber they never worked, always faded, leaked etc, etc, and were junk comapred to the cable operated MX-1's (but for some reason i knew i could make them work and after a few hours digging through seal kits, o-rings and other odds and ends i was able to get consistant pressure and good stopping power out of the 2 pot caliper so it was time to make it work on my bike
For years we've been adapting mountain bike breaks to our 50's for increased stopping power mainly during high speed mini-moto events where soem of these little buggers top out at 70+ MPH (fiddys, fifities, 50's our names for them) I've had an old 8'' hayes mountain bike rotor for my front of my stunt bike (the white one with pink stickers) along with a couple of hayes MX-1 cable operated mountain bike calipers, but due to the change in feel of the disks compared to the old school drums i was looping about 3 out of 5 stoppie attemps on a freshly repaired ACL, MCL and meniscus, so i took the disks back off for another couple years to recover without the chance of being thrown on my face at 30-40mph (stunt bike tops out at 41.6 in the 1/8th mile)
Here's we are another 2 years later and i'm designing the new setup..... to catch back up to where i was befor emy mind drifted... I was in the middle of making the spacers and brackets to ustilize they hydraulic 2 pot caliper on the 8'' rotor (think i might have to step down to a 6 incher though
) and since i was fairly beat from along day of working on customer projects and bidding construction site paint jobs, i just didn't feel like driving throught eh west omaha idiots to get to my lathe and mill in order to cut the new one out (the old one with the 3 holes was cut on a mill) So i took my bandsaw, 4 1/2 inch angle grinder, rotozip with a home made speed control with a few carbide burrs and a large 1/2'' drill ans some bits to start holes to that i had decided to make with the rotozip and burs instead of making that drive.
Well all was going good until the large toothed carbde aluminum bur grabbed soething, the took off and grabbed my ring finger... it dug in and cleaved the flesh, fingernail and all into a bunch of little slivers of flesh hanging off the bone... I kinda freaked when i saw it... then while stil in a bit of shock, i tied a towel around it, rinsed in peroxide and the proceded to lay the bits of flesh and fingernail back onto the finger, (luckily they were all still attached by little pieces of flesh)
I then wrapped it in bandaids after covering it in neosporin and after the pain settled (i live in a large amount of pain daily from an accident in '01 so it wasn't as bad to me as it would be to some i guess) Tomorrow i will peel the band aids and if there's no open wounds i will coat it in super glue as i've done many times in the past and it shoud be okay...might need some antibiotics, but my doc is cool, i jsut gotta call him to get some. The pics are below (might have to make a few threads to hold them all though)
And now back to the mini bike topic, below are my 2 current bikes and all the pics of the brake fab...... OH and the main reason the new hydro need new mounts is it will rub the rim because it's dual pots if i don't space it and the disk out. I am also going to have to take the shim you'l see in the milled version and split it's width onto both sides of the new mount to accomadate the hydro brake system.
The white bike is my stunt bike used in shows, parades, cancer and JDRF camp shows and mini stunting comps. The green one was done for a low dollar budget build contect for plnet mini magazine. It's aptly dubbed "project goodwill" as the frame was given to me all rusted and with about 15 coats of spray pain on it and the tank had been beat in on both side with everything from wrecks to BB guns and even a few .22 holes in it (it was so smashed it would probably be holding less than half a gallon when igot it, IF there wer noi holes)
The motor was also given to the project by a customer/friend of mine. It started life as a china, low compression, low power honda clone at 125cc's wth a 4 speed manual trans,and was shortly transformed into a fire breathing monster with some parts from hondatrailbikes.com and some mad scientist modification with my machining tools :S (the white CRF bike is a 3 speed auto - better for stunting), The white CRF sports an 11.5:1 88cc trailbikes big bore kit, race head with 1mm over valves, a longer intake, medium grind cam and 20mm carb... The green bike is the real go getter... 146cc, 13.5:1 compression (race gas is a must) brian crower did a few runs of cams for the special big valve head that i got lucky enough to score this motor with It has huge nice flowing ports and the biggest valves that can be put in one of these heads). The pipe is a one of fpiece by me being a mix between a CRF150R pipe and a KTM65 baffle mounted on it...the cuts and shaping of the pipe are hidden behind the heat shield i added. The swing arm is a custom pice i just finished a few weeks ago to keep the front end on the ground (the bike makes 14 HP and a tad over 15 lb/ft of torque WOW!) the original swinger is also in the pics along with everything i talked about in the braking fab and stunint chat.
The green bike came to me insuch ugly shape and that china motor was so rough running stock with a crap tranny that my friends girl nick named it the grenade because you never knew when something was going to break, but after very short testing session i tookt he whole thing down, sand blasted it, smoothed all the welds with bodo, eliminated all mounting tabs, took apart and tweaked the shifting mechanism in the tranny and replaced the detent spring while iwas building the big bore high compresson motor from it since i had to go inside to beef the clutch and oil pump at the same time.
Well, that's a damn long story and i'm not sure any of it's in order, but it will give you an idea of what's in these pics and you can see the brake fab work i've done from the caliper brakets i've made (both the milled nice one and hand tool built one i made tonight) You cana lso see the adapter with the notches cutin it that slides where the brake drum use to go and latches to the webbing in the hub of the factory honda spoked rims
enjoy..the two slots i'm pointing at are the only ones that must be there to hol the caiper braket in place....the other 2 on the one braket i did for looks (you can order some stuff almost identical to this stuff, but if i can build it for 1/3rd the cost, i'd rpeffer tohave mypersonal touch on it anyway) The green bike can be seen with it's stock swingarm and the new +3'' one i built to utilize the nice "stoo-lihns" shocks and keep the front end planted in mini-moto races (I call them stohlinz, because the design is stolen from ohlins )
enough jibber jabber, i'm tired..you look at pics and tell me what ya think..almost everything on the green bike is custom made from the bar clamps on down (save for frame, bars, motor and rims and tires) I also painted it and did the body work on my own in my rinky little garage (lucky to have nice compressor and guns )
