Hi Y'all- I posted this on the new users but I guess its not too visible there- so aplogies for the re-post here in tach.
I am rebuilding a CB250 K4- well two actually from a very large pile of bits- I never had one before and always wanted one! Anyway most has gone back together OK and once I cleaned the carbs at least one of them is running OK - the second started, ran and then stopped- so far resisting efforts to restart! However, leaving that aside I have a couple of niggling questions... stuff so obvious that its not in the manuals!
1. Does anyone know where I can get a diagram of the correct routes for the control cables around the frame and under the tank- mine seem untidy and stretched. For instance-Do the speedo and Fbr cables go inside or or outside the fr mudguard stay- either route seems to offer potential dangers of snagging on either the wheel or the scenery!
2. The fuel tap position leads the fuel pipes down, around and across the motor- but actually touching seems a bad idea- should they hang free and if so how do you position that? Similarly the wires to the flasher unit seem awfully close to the head?
3. Does the cross pipe under the fuel tank go under the frame (good for fuel flow) or above the frame tube (much better for tank removal!)
4. The honda manual talks about balancing the carbs by using exhaust pressure- how is this even possible without blocking the exhausts and screwing the engine breathing anyway- but if it is possible how do you do it and what do you use? Haynes just speaks of adjusting them individually and more conventionally.
Anyway cheers- all and best of luck with your own projects!
