Guypie Posted November 22, 2015 Share Posted November 22, 2015 I thought I would make a build thread on this since I never did when I built it, maybe it will give someone that last little kick of motivation to get their velobike up and running for Dromageddon. Heres prettymuch what I started off with: after a bit of cutty weldy etc came up with this: front end not attached it that photo just there for mock up. the rear wheel mounts: one side of the frame flips open so you can remove the engine, I used some valves and valve guides from a mini 998 head that I rebuilt once upon a time for the hinges its held closed by this bolt more to come... 4 Quote Link to comment Share on other sites More sharing options...
Guypie Posted November 22, 2015 Author Share Posted November 22, 2015 Home made clutch lever hinge: Super simple drive train: Slowly starting to look like a thing. I dont have a pipe bender so all the bends are cut on an angle, welded and ground smooth slightly artsy fartsy picture: Made a pink exhaust pipe and intake manifold. Stole the nifty fifty carburettor off the briggs velobike. Also, MDF seat that slides onto the bit that holds the 2 sides together. I thought about using this seagull tank for petrol but decided it didnt look right: 2 Quote Link to comment Share on other sites More sharing options...
Guypie Posted November 22, 2015 Author Share Posted November 22, 2015 Made a latch for the clutch to hold it in the disengaged position out of old photocopier parts, works mint too! Will go take some pictures of the overly complicated fuel system and post them up soon. 1 Quote Link to comment Share on other sites More sharing options...
Guypie Posted November 22, 2015 Author Share Posted November 22, 2015 I really wanted to keep the tank down low so I used a old brass spray bottle, I will probably try to find a bigger tank to use in future as it only goes for about 10 laps before running out of fuel. I dont know how it can use so much fuel because its dead slow, top speed is about 45-50kph. I upholstered the seat in denim. Copper fuel lines are soldered to a steel support Fuel is pumped up to the tank at the top by the vacuum fuel pump. I found the pump made too much pressure to go straight to the carb it would fire up and flood the carburettor almost instantly. so it has a fuel return line with a mig jet soldered into the and drilled out to 2mm to regulate the pressure. it still makes quite a bit of pressure though, I cracked the solder joint on the little tank at the top when getting on it one day and it squirted fuel about a meter in the air wile it was running. I fixed the crack with polyester resin and fibreglass cause thats what I had at the time. you can see the repair in this picture after dromageddon 3 I decided it was too flexy so I put in gussets and the spring for the clutch was in the way, so I moved it to another location. 5 Quote Link to comment Share on other sites More sharing options...
