I have a Japense import 1978. XS650 SE with the Vin 447901xxx. I bought him from Old Gold in Londonderry, in Australia. It was running alright when I bought it but I drove it up the road and back so nothing definitive. I have striped it down to frame to repaint and turn it into a brat/cafe, every bolt off and back on . Now it's all assembled and she is looking good and all is going fairly well ,I am at the final tuning stage. So, I did the cam chain so it was flush. Adjusted the tappet to 004 on intake and 006 on exhaust and did static timing on the points, they were pretty close. However, when I attached a light on the bottom point it didn't shine bright as the top set of points. I moved the copper tang on the carbs when I first got them to something crazy like 32mm and the thing ran mega rich! I now dropped it down to 24mm. So, I have her started and idling and it drive up my drive way but sometimes it backfires and pops the pod filters off and smokes from the carbs. If it drops too far in revs it will stall. I can't take it for a big ride because it's u nregistered, so it's just static testing for everything. (Except the ride today, where I broke down, I needed fuel, so I filled it up and it took like 30 sweaty kicks to get it started after that)
My issues:
1. When I put the choke on, it stalls right away.
2. When I give a quick throttle it stalls, but when it's warm it's fine.
3. When I am in first gear, I get upto about 20km and and it just kicks in and gives me a speed boost. Like a turbo kicks in a car. Kinda scary!
4. I have an oil leak that looks like it's coming from the starter motor. Can I take the starter motor off without taking the engine from the frame? IS that a common place or could it be something else?
5. Why does it backfire?
Are all these issues (besides the leak) timing issues, point issue or carb issues? It's so hard to tell because they are all related. There are also so many years and types of theses bikes that getting the right specs for my bike it hard. I did not mark down where the tappets where at but I adjusted them smaller.
I just went for rego and he didn't pass it because of the leak, then I got pulled over by the cops on the way home. Lucky the guy was feeling pretty generous so just told me off, but I had to push it back to the service station and left it there for the night. What would be the first thing you guys would do?
