Some more parts showed up on friday.
Clutch lever and pertch installed. Cable is hooked up. Still need to adjust the clutch properly.
Master cylinder showed up. I hooked up the brake switches for the front and rear brake tonight. The only wires left to do now are the wires for Hugh's PMA.
I'll be having a stainless brake line made up this week.
New petcocks installed.
Saturday I dove into tuning this thing. I got the correct pilot jets for these carbs from 650 central, still size 30. I also got the air barbs that screw into the side of the carbuerator so I could sync the carbs. I raised the clip (lowered the needle) one slot. So right now the carbs are as follows:
Main: 140
Pilot: 130
Needle: Third slot from the bottom
Air screw: 2.5 turns out (the right carbeuator was turned almost all the way in)
Floats: 24mm
So this is how the timing was set On saturday. It's a little difficult to see in the video, but here it is.
Bill let me borrrow his old school manometer (still uses mercury)
So I thought everything would be dialed in. Starts right up first kick. But the idle was still hovering when I let of the throttle. I called it a day and went home and started reading some more.
Fast forward to tonight. I read that the idle could be hovering because of the mixure screw being off. Checked the left carb, it was good. Checked the right carb, it was turned in almost all the way. so I set both at 2.5 turns out. Fired it up.
The idle seems to be slower than it was on saturday. When I rev it up now, the idle isnt hovering. It sounds pretty good, BUT, I noticed the right exhaust pipe is backfiring (shooting a small flame) out now. I did not notice that on saturday while tuning.
Pulled out the timing light again, and it's off. It's not set how it was in the above video. It's firing closer towards the TDC mark. Maybe I bumped it while tightening down the hold down screws for the PAMCO?
Here's the left spark plug to date
Right side spark plug to date
I'm speculating the ride side plug looks the way it does because of the mixture screw being turned in all the way? Any one else have any ideas?
My plan of attack now is:
1. Pull carbs (gaskets are leaking anyways) Clean all passageways thoroughly again. check float heights again. Clean all jets.
2. Re-adjust timing. I'm thinking this is also a part of the problem along with the mixture screw.
3. Carb sync again, because I'll be re-adjusting the timing.
4. Check exhaust gaskets, make sure pipes are in tight.
5. Check to make sure carb holders are not leaking air. I don't really see how they could, since they are brand new and hose clamped
When it comes to the timing; does the bike need to be idling at a specific RPM?
I'll get going on the above plan. If anyone has any other info let me know please!
Soaking up some rays. I can't wait to get the pipes from Gordon on there.
