Hello,
I was going to restore a Tora for my wife to use as a pit bike, but I wanted to do something different. Since she grew up racing Flat Track, I decided to build her a cool Flat Tracker. It was a lot of work, but it was worth it. She'll be buzzing around with it at Vintage Days this weekend!

What a neat bike, looks like a SR100 Luke

Very cool. Brings back memories. I had one as a trail bike that we tried an SR motor in to hillclimb. The frame was way to flimsy and it didn't work out. You've done a great job here. I like the look of the pro plates,it gives it nice scale. Can we see some more pictures of the carb and pipe? Mark.

I received a really good compliment from an expert vintage collector last weekend at Vintage Days. Tom White, owner of "The Early Years of Motocross" museum, saw my Tora and all he kept saying was, "Bitchin'! That thing is Totally Bitchin'!".
Here are a few pictures of the exhaust pipe and carb.
The front half of the pipe from the motor back to the welded seam that's directly under the brake pedal pivot is from a '82 Honda MB5. The pipe from that seam back to the univeral silencer is from a '79 Suzuki RM80. The chrome clamp that's around the silencer is an ignition coil mounting bracket that I found at Autozone. The bracket that supports the silencer and goes up to the upper shock mounting bolt is one of the original rear brake stays that I bent and then had it rechromed.

I wanted to have an exposed carb, so I cut away as much of the clutch cover as I could (this is what my Dad did to his Bridgestones when he used to race them). The stock Tora carb is small and not very intimidating, so I found a bigger carb, a Mikuni 17-18. Since this new carb has a bigger intake diameter, the spigot on the stock Tora rotary valve cover was too small, so I had to find another valve cover that had the right size spigot. The 60cc motor is stock, so I put a washer in between the carb and spigot to act as restrictor so that the motor could handle the bigger size carb. I must have gotten it right on the first try, as the bike was ridden around at Vintage Days with no starting problems or fouled plugs. As to the air filter, I wanted one of the vintage green foam filters, but I couldn't find one small enough to fit the carb. I ended up having to machine an adapter out of aluminum and pressing it onto the carb.

I also cut away the flywheel cover to expose the front sprocket.
