Spark plug fix

Recommended Posts

Hey guys does anyone see a problem with using a helicoil on a 01 xr 250 head? The hole looks to be really close to the valves. New to the board, I just bought the wife (myself) the Xr and I ride a Cr 250. thanks For any help

I think it's the preffered option when you have a hole that has been buggered up too bad to save. Definately want to make sure you do it's installation right the first time tho. If you're not comfortable with it, get a pro to do it.

I think you should get a timesert fitted by a good engineering shop for the sparkplug threads, it is a more permanent repair for that tricky area.

Also you will need the honda plug tool to get a plug in and out (because there isn't much room)

I just put two helicoils in the head yesterday. They were for the valve cover bolts over the exhaust ports. I have a full service machine shop in the building where I work and that's what the experts recommended.
