what is the ratio of a 92 blaster 250. also how can i tell if its a 250 or 125. its old but i can still see the vin?#

 

I thought all blasters were 200's, actually like a 198cc.

I could be wrong. Also they are usually injected unless someone has used a block off plate in that case it depends on the oil you run. I run yamalube at 32:1 in my banshees.

All blasters are 200(198cc) unless a big bore has been installed

 

 

The injector pump injects the oil around 20 to 1 or 25 to 1. If the pump has been blocked off mix according to oil manufacturer. I mix Amsoil 50 to 1 in my 250r and Blaster
