Not sure why your motor wont start, you would need to give more info on what you have tried so far, I would like to see how you managed to fit the FG in a raptor, can you post some picks.

some of the alluminium was used as mockup sides just to get a measurment

fg baja 26cc engine,,,,,it has its own fan on the flywheel so no need for the fan shroud off the 90,i just cut the shroud in half and used the clutch

Well done, I think the reason more people don’t use the fg is its a bit on the heavy side plus they only use three bolts on the head but its certainly the cheaper option by far, nice job.
