1978 CT70 Resto Mod Part 4


Now the fun begins!  This was the second 125 engine I had installed in a CT70.  They open a lot of doors as they have big power, CDI ignition and a 12 volt charging system, meaning lights are considerably brighter even if you use a voltage drop and reuse the 6 volt bulbs.
Again as Josh says, just two bolts and the engine’s in!  This engine requires throttle cable and twist grip changes.  Also, as it’s a 4 speed manual, a clutch lever was added.  The colourful decals were applied, following the location recorded before stripping the original paint.  A gas tank was cleaned, new lines, shut off valve and gas cap were all installed.  The rear brake pedal and rod, return spring and small parts were cleaned, repainted and installed.  As the bike was going to only be used off road, the awkward turn signal arms were left off.
As a bigger engine works nicely with a free flowing exhaust, an order was placed with Motor City Mini Trails for one of their Super Stealth exhaust systems.  It took a few hours of heating and bending to get it to fit.  Hopes were high that the power and sound would be worth the high cost.  At about $290 US, that was pricey.

1970 Fox Minibike Part 10- It’s Alive!

As the tires on the pit bike were worn out, a choice had to be made as to what would replace them.    The little 2.50x 10 size is available in many styles and brands. I ordered a pair of Michelin Starcross tires as they had an aggressive knobby pattern.     It was also a chance to remove the wheel bearings from the hubs and put new ones in.     One of them was a bit loose in the bore, so a prick punch was gently hit in several places to raise the surface the bearing sat in.     I couldn’t find new wheels at reasonable prices, so a good rubbing with Autosol made them shine as much as possible.     The new small tires were tough to install, as the bead is stiff.     Dish soap and patience prevailed! Well, after three months of working on the bike project, the day came to fire it up and take it for a spin.     I changed the oil and put a new drain plug gasket on, not knowing when or if ever the oil had ...

Classic Mini bike Engines

Making a Tecumseh Snowblower Engine Look Vintage As a kid, the Honda bikes were what we dreamed of owning.  Their motorcycle feel with steering head bearings and a transmission were high end features in a day when lawnmower type flathead engine powered mini bikes were the norm.  I remember as a kid, looking for the reel type lawnmowers that had horizontal shaft engines.  Hoping to find one no longer being used and pulling the engine off to put on a mini bike I didn’t even have at that point!  They were around in the late 60s, early 70s, but were usually 2 or 2.5 hp maximum.  My first “go kart” was one my Dad built, using parts from an old baby carriage and a sheet of plywood.  I pestered Dad until he finally conceded to find an engine to bolt onto the back of it.  I believe it was 1967 or 1968 in Ancaster when we found an old outdoor wringer washing machine engine.  Yes, gasoline powered washing machines were common up to the 1960s....
