UPDATE:
1. The bike has about 500 kms on it now and has been totally oil tight !!
2. The rings seem to be seating on the barrel and the compression ( gauging from the kick effort) seems to be increasing.
3. The VM28 has been added to the bike and the jetting needs to be sorted out now.
4. The best part - The de-compressor delete ( never used it anyway) !! And the spark plug from the AVL engine ( long reach) was put in its place. Added an extra ignition coil ( series) and tested both the plugs for spark - and they both give a strong spark at each plug!
Now I have a lovely zippy Cast Iron Twin sparky (maybe more pollution friendly also now) .
For the sake of experimenting, I did no modifications to the head, spark plug( long reach) etc as discussed in another post and it fired right up with no compression losses.
Interestingly staring the bike with only one plug connected and then connecting the second plug results in the engine rpms rising by a couple hundred. I am guessing the additional plug is probably improving the combustion efficiency
Now to ride it like it is and evaluate if this additional plug and play will hold out.
Cheers !
