Ok, lets start again.
Goldwing 1000 correct?
has a primary reduction of 1.708
a secondary reduction of 0.825
giving 1.4091 overall reduction of crank to the input shaft.
1st gear = 2.5
2nd gear = 1.708
3rd gear = 1.333
4th gear = 1.097
5th gear = 0.939
Final drive = 3.40
Lets stick to your 4000 rpm
Eng = 4000 divided by overall reduction 1.4091 = 2838 rpm at the input shaft.
Output = 2838 divided by final drive ratio 2.78 = 1020 rpm at the wheel.
To convert to MPH = engine rpm x raduis divided by final drive ratio x 168
4000 (rpm) x 4.43inches (tyre height) plus 7.5inches (half wheel diam) = 4000 x 11.93 = 47720
1.78 (primary reduction) x 0.825 (secondary) x 0.939 (5th gear) x 2.78 (final drive) = 3.83 x 168 = 643
So 477720 divided by 643 should give you 74mph in 5th gear at 4000 rpm using your current diff/wheel setup.
you done this just for me.Thanks tbone  now what would it be if i had a 3.55 diff and 205 60 15 wheels  only joking thanks again |

I`ve got a headache !!!!!!!!!!!!!!!!!!!!  So 74mph in 5 gear @4000rpm i will put that to the test when ive set the carbs up |

Why? Why?.............I know I`m doing it but I just keep on typing and my brain overtakes my fingers.........................it`s a sort of tactile diarroah diarheah diarrhoea runny bum I suppose.............doubt I`ll ever learn.............but if it makes you lot smile then that`s fine by me.............if it doesn`t then B****x to you
Sadly I can`t make Basingstoke now, it sort of crept up on me and I`ve got a lot of organizing to do for The East Anglia D-Day Memorial Ride on the 4th of June. Besides that not feeling too good this week. worked on Cuddles trike all day Saturday and I`m paying the price now with a very stiff neck and can hardly walk. Hey ho life goes on. |

Trikes sick only running on three cylinders use nearly 8 litres fuel on a 10 mile run. i will get more if i put a V8 in it no. so cant ride it so i will be in the van with the trike behind me going to basingstoke Took the carbs of again (ground hog day) to see whats happening. i pinned it down to the carbs on the near side.drained the fuel out of the bowls.took the bowls of all seamed ok.then when i checked the floats no 4 was stiff so wasn't closing properly.on investigation i found the pin that holds it in place was bent.how it bent i dont know.so to the spares box new pin fitted and checked for level and movement.put all back together.then tested by pumping fuel in to check for leaks and that the valves are closing   will put them back on trike tomorrow be glad when i have sorted this single carb conversion better change the oil as well probably a bit thin now |
