:confuse friend and have ran into a stumper. The bike is a 85-88 model, it has 120 psi of compression and holds it pretty long so i know the seals appear good in the bottom end. It has 2 gallons of new premium gas in tank and good on oil and a brand new plug i got at the dealer. my problem is that it will only run on ether and not the gas  and it seems to crank along d:  I am working on a trailboss 250 r/es for atime to start and run at all. Any info?  

carb could be clogged.
the compression is low, the trailboss 250cc should be getting around 130 psi.

but if it is starting with ether, then chances are you have a clogged carb, and it isn't getting fuel through the carb.

try removing the carb and cleaning out any fuel gum and use either a wire bread tie with the plastic coating removed or using a .10 guitar string to run through the jets to make sure they are clean and clear.
if no luck there check the fuel tank shut off valve for trash or debris.
