got the '75 tank in saturday (MAN that was fast shipping!!). other than one small dent it's in good shape inside and out! dual petcocks should make fuel line routing a bit easier and allow for twin filters.
also decided to pull the motor and do a good inspection. this will allow for better piece of mind and a good chance to clean up the frame and hopefully re-do the wiring harness. will install a PMA and Pamco when i'm at it. checked compression, 150 on the left cylinder, 120 on the right. don't know why the difference, but i'd rather be safe than sorry. hopefully i don't open up a can of worms! bike has 16600 on the odometer, but no clue how long it's been sitting, judging from the carbs.
any other advice on what to do since the motor will be out? again, going for reliability and a little bit of power, but still on a budget. planning on cleaning up the cylinder head runners and combustion chambers; mainly just casting defects and that, no major porting. hopefully pistons and cylinders are in good shape so a good hone and ring job will be all that's necessary. will most likely address oil cooling while i'm at it as well. don't know if i'll go with an external or Mikes adapter for the right side case.
finally, anyone have any good lists of "must-replace" items and where a good supplier is for them for an engine overhaul like this??
