Hello Ratrodbikes forum! this is my first post I believe and i figured this would be a good way to start! with my recently started project I will begin with a drawing
I've been working on this idea for a while, this is basically the final revision. originally i was going to build a full on custom board track racer style bike, custom frame and the whole nine yards, but then reality kicked back in when i remembered that i don't have a MIG welder or any other useful metalworking tools! what i DID have was an 85cc tecumseh two stroke motor from a snowblower, and a couple of western flyer bicycles!
the ladies bike will donate to me its front and rear brakes, forks, and shimano 333 3 speed rear hub to be mounted on the other bike. today i made a mockup of the tank, flipped the bars and a few other little things on the bike. Its been HOT. 89 with a heat index of 107 today, wasnt too bad with a fan blowing directly at me! :lol: I owe a LOT to my good friend Simon for helping me figure some of this bicycle specific stuff out (i'm a total noob when it comes to any of the more technical bicycle stuff) and with the gear ratios. for simplicities sake I've decided to order the bulk of the parts from GoKartParts.com, which also has some of the lowest priced parts i've come across. The parts chosen are as follows:
*12t #35 chain 5/8 bore max torque clutch
*5/8"x10" jackshaft kit (13t and 18t sprockets)
*c35 chain 10 foot roll
*ccl-35 connecting link x2
*72 tooth steel sprocket #35 chain
all of that means that i should have around a 10.6:1 ratio in third gear with around a 50mph top speed. and stump pulling torque in first :lol: The motor, if you cant tell, is an 85cc tehcumseh 2 stroke which is 2-3hp stock if i remember right. it will be getting some mild port work, a tuned exhaust pipe, and a new carb which should be good for a little power boost i've come up with what i think will be a more than adequate mounting method for the motor, without welding! here is where i sit right now, cardboard tank mockup and all
more progress as i make it! i wont be ordering parts for a while yet, but theres a lot of progress to be made without spending anything yet! please let me know what you think
