Thanks Motogrady, just wanted to update the thread - so I've been having fun riding the bike every now and then and I'm really very thankful to all of you guys who have helped me get this thing running. There are just a couple more weird things I have noticed that I need to iron out:

1. When the bike initially starts I hear some sort of metal hitting something somewhere on the engine like "tak tak tak tak" while the RPMS are still low and the engine is not yet warm (I usually have to use the choke) - only after about 5 minutes or more (and when I'm no longer using the choke) and the RPMS seem to have stabilized and the engine is warm do these sounds go away and the engine runs smoother - what could be causing this "tak tak tak tak" sound? Is this normal?

2. I noticed my left exhaust / muffler spits out noticeably darker smoke compared to the right exhaust / muffler - like a 3 is to 1 ratio - what could be causing this? Could it be the plugs? Could it be related to item number 1?

Thanks in advance
