i got a new head the other day. I installed it today and the scooter does not run. It's a 47mm head. it was the only one the guy had at the scooter shop. I have a 47mm kit on my scoot so I thought it would be fine. I needed a new head due to a stripped stud hole
at first it wouldn't start, then it started but it would not idle, then i got it to idle but i had no power. I was going maybe 3 mph.
then I adjusted the valves again. I found the bolt on the exhaust rocker came off. I guess I didn't tighten it enough. after that it ran ok up and down the alley. When I tried to start it again, it would not start. checked my valves again, they were around .004, where they should be, right? I have spark because I was able to start it here and there. do you think I am not getting fuel?
I have noticed that spacer thing on my intake was not lined up with the hole on my new head, could that an issue?
I don't have a compression tester at the moment. Would a bigger head raise or lower compression and how is it resolved?
Thanks
