If its an abs bike make sure its working.
I put almost 100000 miles on mine. I still had the same cct and valve guides that came from the factory. The bike ran just as strong as the day I got it.
Our 1993 Kenmore (made by GE)side by side with ice maker has not had one problem since it was installed. I also have a Kenmore freezer in the Garage that was new in 1988 with no issues. Now I probably jinxed everything.
Had a friend that just used the bigger jets in his.
Just didn't turn it up all the way.
Don't see why you can't plug and re drill though.
You might try a shop that sells and installs high end BBQ's
