Yama Goped Project

[adidasguy]

Go simple for reliable transportation. baby it and don't try for 55mph on a goped. Ride slow and easy and it will last a long time.
You don't have to set records on a goped. Maybe you over stressed them and they didn't like it.

What happened to MotoHuffy motor?

[yamahonkawazuki]

Considered motohuffys plant. but id have tofab an engine mount, a different wheel OR pinion gear, because of the pinion gear is different versus the drive gear. the needed drive gear would be almost 4x thicker than the drive gear on it, so id have to find a shiner wheel, and tire, gear mount etc etc . the Chinese 49cc engine I found I remove the transmission, and it will bolt right up to my clutch housing. if I have to replace anything, it would be the clutch. doesn't even look like id have to even do that. the Chinese engines, are quite reliable. I have owned them before. that's the route I believe ill save for. theyre common and fairly inexpensive.

OR flip wheel over using rear brake disc, and put drive gear there. plus usea fabbed tube steel rear engine mount. and exhaust. id spend more, in fab versus purchasing china engine. the 159 china engine, i remove transmission, sell it for 20, and flip engineand bolt into PMW engine mount. So way im looking at it is selling transmission, id have 139 tied into new engine. minimal fab. not having to worry about clutch or setup. worst case scenario, is i remove the china fuel tank, and use the PMW fuel tank.  on opposite side. or if able to use both fuel tanks, i can end up with a dual fuel tank arrangement.

BINGO

can make this fit. using either the billet engine mount, or the mount included.  either way.  this is the engine for me. time to start saving 

[yamahonkawazuki]

heres the photochop mockup of the pig with a Chinese heart. ( dependable engines. stock close to same power levels but lower rpms. have owned these engines before.  case reed induction engine just a hair above scale exhaust will fit but will be tight. but doable. cag conversions have been done on gopeds before. sacreligious as all getup in the goped community. but I don't care. id rather do this than be still for much longer lol
and 75 shipped cant beat it lol.

I can only think of one word: COOL 

[yamahonkawazuki]

Theyre as addictive as the gs500. guy I got it from wanted to trade me a Chinese 50cc sit down scooter. running and rideable. I declined. this is the only trail ripper in east tn atm. 4 gopeds in Clinton area, ive owned 3 of them lol.  going to keep this one.

[yamahonkawazuki]

heck I think ill tear open the pigs engine, and see whats up. wd40 what im going to keep etc. eventually will rebuild this. but am going to take my time. in meantime going to grab one of those Chinese 50's ( spare engines are nice to have. lol)

[yamahonkawazuki]

this was the fastest recorded run I had made. that paseo I passed, I saw between 35 and 40, ill split it and call it 37.  after I blew the secondary chamber in the exhaust, she went faster. but nearly impossible to keep in tune. ther is no margin for error on this walbro. hoping things work out and im able to order the engine by mid to late October.
this was run number 8 that I recorded.

the Chinese engine, a few ccs larger than my 420, but maybe a half hp less, since ill be running at 11k versus 16+k. may sell my trailtech vapor and or the gerber river knife to partially fund the engine. wont be able to find another vapor at the price I gave for this one. but heck, who needs a speedo lol.

[yamahonkawazuki]

I was a bit squidly here. trust me there was plenty of room when I crossed the highway. I promise

Here you go how to really McGyver up a goped....

I saw a coupon for $99  portable generator from Harbor Freight. BUY IT!

Get some old electric train or trolly car controls.
You mount the generator somewhere on the bike and hook up the controls.
Next you install an electric motor to drive the goped.

WOW! An electric goped!

Be sure to wear a conductor's hat when riding. Use a trolly bell for your horn.

Now I can really see you doing that!

(And the best part is no more chain or clutch to break!)

[yamahonkawazuki]

Honestly if it werent overkill, id grab something like that for its engine. usually similar in size to the one im tempted to get. still cant beat 75. tbh i had thought about converting it to an esr750 powered goped. ive got nearly8" of ground clearancebut oye after checking th epricing and pieces involved, nvm lol. ill wait on the 75 cag

[yamahonkawazuki]

found clutch shot of the vertical Chinese engine
the horizontal Chinese engine will work too. more I measured it.  measured the spacing it will clear the deck with minimal modifications

[yamahonkawazuki]

going to run the cag engine. ( the horizontal one) its half the price, and reliable. nearly impossible to blow up lol. plus easier to tune via the case reed induction. getting stoked. should ( barring problems) have engine on hand and installed within a month.

[yamahonkawazuki]

shopping exhausts to get list together. the OEM exhaust for the cag engine is 26" long. but inexpensive. ive access to a welder. ebay is funny  they offer a gy650-150cc exhaust a universal fit lol. kinda have to be a tad more precise than that. will probably get the stock can versus the header/exhaust. its roughly 4"x3"x2" roughly. and quiet. as addy put it, stock works. stock = dependable. or as was put before GPN crashed yet again lol, there was an article written 5+ years ago. stock outlasts all. mildly modified outlasts slightly more modded. and so on so forth. heavily modded = short life. I think ill stick with the 84 tooth drive ive got now. if I upgrade, will be to a higher speed gear. main reason is, like our gs, you go that route, you go faster, but revs are down. if I go back to a 6/98 shell move. but shell scream too. now im at 7/84, might consider 7/76 or 7/80 and choke the fuel back a bit via the reeds

[yamahonkawazuki]

I work in a pawnshop/gun store. I sell, guns, jewelry, tools and oddball things of all sorts. I pulled 16 toolboxes full of various things. ive seen it all. even adult toys. ( which are disposed of using 3 rubber gloves and double bagged)  anyhoo, said ive seen it all. I found this in a box I pulled to sell today. I asked, and they allowed me to keep it. its 6" long and titanium. very light. and very hard. ive also got a quarter ton of titanium slugs, which were supposed to go to TRW. but if they hit the floor of the facility, theyre disposed of. I kept them to build chess pieces. anyhoo back on topic. if I could find another one of these, ive got a bitchin set of handlebar grips. but I wont. cause these are VERY expensive. if purchased via dealers or providers. Sooooooooo, going to make a 90 degree mount, and set this thing up on either my front SSSA or the rear SSSA as a camera mount. positioning camera rougly 6" above the tarmac. Hmmmm, as a camera mount, I can also set it up as a deployable kickstand.

Cool .. But what actually is it?

[yamahonkawazuki]

cant say yet. if I won the what is it game, its the next entry.  if not, answer should be up today at some point.  ill just give a very vague clue.   ........ For some folks this is a necessity.......  ( said clue)

[Janx101]

Ohhhh ... Pogo stick head unit clamp thingy! ... Necessity!!!

[yamahonkawazuki]

a titanium structural member of a bipod. but said bipod is not part of it. it is part of the bipod. contest still open my friend. so cant say much yet. maybe within a day. its former owner hasn't returned for it, so ill keep it. I was being nice. since these are not cheap. and waited in case he needed it back.
