True story

i did a job for shaner and he gave me another hobbit. there's already enough of them around here so i figured i'd go ahead and cut another one up. i wanted to make a little racing style lookin bike for myself since all of mine are anything but that. check this shit out

might as well go all the way and start from the beginning. i put a piece in there to stretch the frame.

it seems like i didn't do anything here but i did. the curved bar is shorter up there by the head tube and mounted lower on it. and there's an extension piece at the other end

now the frame is longer in the middle and still holds the same wheel base

i capped off the back tube so it doesn't have premix going all through the frame. WTF!

this is the seat...WTF! yep

see, i bent it into shape

mock up pic.    alright?.... alright!!


whoops! there's more. lets back track a little

ridgid scmidgid,, fuck yea, i'll do it! fire escape ladder bars cut to make the arms. with that, let me say that i hope no one gets trapped in a fire because of me needing material.

i made a few gussetts for strength! make paper templates, transfer to 18g. steel, cut out, tackweld in place.

YUP! it's a top tank too

i still have a little ways to go on this one.
it got really cold so i brought the bike in and started working on the seat cover. i didn't know anything about sewing so momma gave me a 101. i cut some paper templates, then adjusted them, then traced'em on the marine vinyl. i'd have to say,,it's nice to make a part without noise and sparks.

that's a good start, but i really need to get the frame done. i took it back out there and tore it down again. i got the welding about 95% done.

also, i have all the engine parts together for when i get to it. more fabbin and figuring shit out which is what i like to do. + it looks neat!

i

i traced the rear fender curve and the frame curve onto the template to get them pieces figured out

i got the peddles back on, hooked up and working. 

 i made a new gas door and put some cabinet hinges on it. it shuts real nice with some light spring action

so now i can finish the seat cover.

 i cut up the rusty hobbit gas tank and made the fairing. the windsheid is a lexan helmet visor.

i put the engine on and made up some of  the engine covers.

the engine i've been using for these mock ups is the one that came on the bike. i haven't had a chance to tear it down and rebuild it.
For the past few months me and RickEms have been swapping engine info between the Hobbit PA50 engine ^ and the one he builds and uses the Urban Express NU50. they're both honda duel variated engines that are similar in some areas and completely different in others. it's kinda strange how a company can make two different good engines the same size. so, RickEms brought over a few of his NU50 engines and we discussed the better parts of them stock. like, the no rev limit cdi.and it also runs bigger reeds.
we discovered that his flywheel, which is facing the opposite way of a hobbit, fit the taper of the hobbit crank. the problem is that the cdi unit is attached inside the cover plate and the cover plate only bolts onto the urban NU50 case half. so i started making a bracket to hold the cdi in place without the cover. i ended up not having a lot of time to focus on the project, so i sat it down.
the next time i got a chance to mess with it, i took the NU50 case half and put it together with the PA50 half and looked at how they lined up. it'll work!
i put the bearings on the hobbit crank and had it ready.

this is the Urban Express NU50 case half that i got from him

here's what happened...

i cut and removed a 3/8" x 2" chunk out of the case where the top transfer meets the cylinder boost port.

i made a plug to cap the hole in the engine where the oil injector was. it used to stick out like a pipe  but i cut it off and grinded it smooth. i put some jb weld around the lip of the hole and drove it in with a hammer, then sealed it over with jb weld

then i drilled a hole for the bearing to get lubed by the premix. i dremmeled a little notch above the hole. i guess it acts like a funnel to catch the oil and get it in there. the hole was already on the hobbit case half from the factory so i just copied the idea over to this side, which for some reason they didn't put on this engine.

the other side of that hole goes to the bearing so i notched that side too. again, it was on one engine but not the other.

i put the crank in and bolted the two sides together.

i put the cylinder kit on there and pipe then put it on the bike. i hooked up the coil and cdi.
                                          it started!  

it's getting good spark now and the cdi is said to have no rev limit. uhhh... good enough i'll take it!

i got this (black) piece of a dirt bike expansion chamber from RickyEms. he had it on one of his bikes for a while last year. it had a few other pieces welded to it, but i cut them off because they had huge gobs of weld all over and it was disgusting to look at. we looked at it and discussed how to make it work better. the result of the conversation was to add a longer header and a tapered cone leading into the chamber and a nicer one tapering out. i measured the proma pipe specs (the bronze colored one in the picture above). i took them measurements and made the cones out of sheet metal and 24mm i.d.steel tube (chair leg)

 i hammered the back cone into shape. it took about 45 minutes per side to get it looking right.

 it turned out pretty neat. i was gonna make it come out the other side but the kickstand was in the way of the header.

 

i got a Dio reed valve, but the cage that holds it wouldn't fit in between the frame and engine. so i made the part that i needed by cutting some 1/4" steel plate to fit the case opening

 

then i cut a plate to fit the reed valve

 the sides are angled to lean it back enough to fit the intake in the on top of it.

 i had to put a couple studs in the case because the base plates are so close together that a bolt won't fit between them

 the intake tube is also mounted to a piece of 1/4 steel. it flares out to the base to spread the flow out over the entire surface of the reeds

 the whole thing assembled fits in there with 1/2 of clearance from the frame. that black thing sandwiched between the 2 plates is the reed valve.

 

i got the engine parts made up. now i can get back to the body parts. i made the louvers in the sides of the engine covers to resemble a mustang

 

i made a headlight out of a harley davidson headlight, cut down and adapted to fit in the fairing

                                   i made a compartment for the battery and wires and alarm

                                                                     the dash panel

 the flywheel cover said honda on it, i sanded that off and dremmeled this image in it.

 

o.k. so you lookin' at it and there is no tank. but there is a tank. and thats o.k. cuz it just another f'n moped

im getting ready to paint some of the frame black to accent the red

th

lexan helmet visor windshield

 

here a pic of the dio reed adapter and intake^

i hacked about 10cc's off the pipe hahha  that big lipped muthaka was scratchin' the paint! i'm sure there was plenty to spare.

the front fender has a lot of work done to it too. i cut a channel and wrapped it around the existing back side bracket as a stabilizer. i wanted the fenders to be 4" off the ground when finished. WTF why?.... i rode in the rain earlier this year on a hobbit that i did this fender mod to. so much better than getting water sprayed off the street into my face. that was one of the things that had to be incorporated into the frame and finish.

i gotta get it back to chili to get some white up there on the fairing sides.

i don't know about that pipe wrap shit i might just hose it down with some bbq paint.

this exhaust was crazy loud ^ so i took the kids tee ball bat and made a muffler outta it. pics below. it works pretty good and you can hear it from 3 houses away instead of 3 blocks.

i got some of that vinyl pin stripe shit, alcohol'd the wheels dude it up, then let it sit in the sun

thanks for looking, it has been my pleasure to create something that i can ride and hopefully inspire others to get out there and make it how you want it. -scooter trash <3
