My "Thai" Yamaha Y80 Belle"Chopper"

[davidstipek]

This Thai Bike (Y80 Belle) helped me give her new life...

Everytime I left Thailand to return to America and something broke or failed on Bike and it could still function... it got removed or cut out...lol (Daughter trying to save money)

I found out when my wife could not shut off (Ignition switch had been disabled) She had to rest front wheel against phone booth and apply power and stall engine. So I put bike in storage...that was 10 years ago.

I wanted to get China 80cc engine and install on Bicycle, but it wassingle speed andnot very reliable I was told. So I took a good look at the Y80. Engine was long so I was going to need to extend frame of bicycle ( I used 2 steel mens and ladies reinforced all tubing, used front half of ladies Bike and turned it upside down to give headtube the chopper rake (angle) EXTENDED FRAME 18.5 inches and lowered seat 14 inches. Used original BB and axle set with addition of sealed bearing for petrol power transfer from left sideof bike to right side. Added second BB and axle set for pedals and moved it forward for same leg-stretch as 26" mens bike had. Now instead of pumping pedals, you push...easier!!

All 420 gearsets have HD freewheels 4 bolt that fit Yamaha sprockets perfectly total of 4, (1)at pedal/crankgear, (2 & 3) at lft and right side of bike at original BB. Right side wasn't needed, but if you were using pedalsit stopped axle from turning (Resistance) much easier. Both of these insured not having to find neutral in a hurry if engine died. Just start pedalling! and (4) at rear wheel.

Front fork is a Kawasaki full oil suspension. Rear is Hardtail as original early Harley Choopers were so I added dual springs to center of my 2up seat.Rear of seat is with pivots and front has flat bars (2) that fitt under tank and let seat function with springs.

Used dual Disc brakes and right hand cable lever has brakelight switch. Left hand rear brake has Honda switch attached to Caliper arm to arm brake light. I switched power and controls from 6V to 12V and used 5 micro LED's for brakelight in star form and 1 incenter for taillight. The turnsignal lights are 91 spade plugin bulbs and all lighting fixtures are Bicycle. My Dad still had my first bike with Miller wheeldriven Dynometer lights in loft of our Barn. (I used tail light and Headlight)

Visit my album for detailed Pictures. I have attached only One here.

Enjoy! Questions? go ahead and ask!

Cheers,
David

Thanks for your visit and comment! Sometimes when we design on edge... Not sure what reception will be like.

So far everthing has been positive. The ideastarting out was to find a way to put lights on Bicycle so even have when not in motion. Something that that would be secure on bike and not removed so easy. I kept coming back to the old Dynometer wheel driven. I still had the Miller light from 50 years ago on my first bike (stored in loft @ our Barn in America) So I added a 6V M/C battery and a selenieum rectifier to recharge Battery. I was tired of seeing AAA and AA batteries discarded along bike routes.

It worked,we changed batteries to cell phone style. (2 x 3.4V= 7.2V) Less weight. Then I changed to 12V as need kits are this voltage. This meant 4 batteries,still fit under seat okay. Also switched to 4 wire Honda Rectifier, this included a regulator so didn't spike bulbs..results were good.

Now here in Thailand, we have a LOT! of bicycles on road, 2 wheelthree wheel, Push and pull work bikes(3 wheel). Now I had a way to offer lights for early AM and late night operation safely. This was my goal!

I then thought about adding petrol power,so older riders could do so without using much energy. But China motor I think not too reliable so I recycled small M/C power and had positive results.

This was where my Chopper was born
