## Questions & Answers

**Q: how can i tell if this old do a standard motorcycle spark plug hole 250 cc yamaha motor**
A: You need to find the thread diameter size of your spark plug. Look up what NGK plug will work for your bike and then check this site: https://www.math.uwaterloo.ca/~rblander/NGK.txt
Field one of the NGK code is thread diameter size. Then get the appropriate helicoil kit. Remove the head before drilling out and repairing the threads or you will get metal shavings in your cylinder and ruin your engine.

**Q: is  Inserts stainless steel or steel ?**
A: They are made from Chrome Vanadium Steel. I’ve used my set several times now and it’s a decent quality kit.

**Q: Can you supply me with a kit for my stihl chainsaw  ms 251 spark plug ??  plug # ngk  cmr6h !!**
A: No, I purchased this product, this is not how you contact the seller.

**Q: Are the Helicoil made out of Stainless steel?**
A: chrome vanadium, like many hand tools, such as wrenches.
