Sorry for all the questions but I havent had a 250R in 10 years; still refreshing my memory.
So I pulled the carb off to make sure it was clean and re-jet it. It is the stock PJ 34MM; to my surprise I pulled off the bowl and it has a 178 main and 60 pilot jet; Now the quad has a 19CC Dome on C-12, FMF pipe and silencer, and porting, but still that seems like some serious jetting. It was in Las Vegas at 2,000Ft and I am at sea level. So, I need to jet it even fatter? Like a 182 or 185 main and like a 62 or 65 pilot? That seems excessive. Lastly the quad had a B8EG for a plug in it. I always ran a B9ES in my 1986; I think I am going to try the colder plug and see how it runs with the jetting it has now. Any insight is greatly appreciated.
