Re: 45mm bore
Yes I have changed the plug. Checked for spark and checked compression all three I believe to be fine, I don't have a compression tester but I put my finger in the spark plug hole and it blew it out with plenty of force.

Re: 45mm bore
Also will the stock head fit well for compression or is a 51mm head better I don't have a 45mm is that a must or will it run with one of the two above?

Re: 45mm bore
Put a 48/120 in no 118 do have a 115 tho. It's about 50 degrees here running a brh8s plug. And I am only about 170feet above sea level. I know these conditions will Change the jetting. Couldent see to get her started with the 48/120 think I might try the 48/115 combo. Thanks
