Best oil for break in?

I cringe when people come to my shop with a 'sitter' carb job, or low compression and fog it with ether to get it going! Waiting for it to pop a crank seal everytime! haha

I tried that once when I was about 14 when I was working on my first cz and the old guy that was teaching me about the cz's bout broke my hands. Needless to say after a detailed explanation from him I learned a lesson without any cost involved.

use a low pressure fuel pressure gauge.  i'll post a link  nice BIG gauge and easy to read.  i'm not sure if there is a post in the "build" thread  but i use a T fitting and link both sections together  not just rely on the crank labrynth seal to leak.  

 

something like this works great.

 most auto parts stores have them in stock for around 20-25 bucks.  i have a few fittings setups for twins and singles ( pvc)  then just transfer my gauge.  after i built mine a few years ago its been a great asset.  any good 2 stroke guy this should be number one on ANY issue related to runability.  i have been amazed at the leaky intakes i have found and center cases with blown sections on the bottom from bad build quality.  i even used it when i built the intake for my teryx to bench test it before i ran it.
