They are about 50$ and I may have a similar size bit. It's to ream out the valve guide to the correct size , the Manuel says to ream it out , why it's not made at correct size I don't know.

rmaynard 14,926 #3 Posted July 1, 2015 ...why it's not made at correct size I don't know. It starts out the correct size, but as the guide is pressed into place, the hole gets smaller and needs to be reamed back to the correct size. Share this post Link to post Share on other sites
rick 217 #4 Posted July 3, 2015 A reamer and drill bit are two different tools... Share this post Link to post Share on other sites
timm6528 0 #5 Posted July 3, 2015 Thanks for the input guys, and I agree in the deferent tools, but really, what is the deference in a 5/16 drill or 5/16 reamer after one or the other was put thru the valve guide. ? Share this post Link to post Share on other sites
Howie 884 #6 Posted July 4, 2015 Depending on how the drill bit is sharpened, it can cut oversize. Unless the reamer is oversize it will not cut oversize.David Share this post Link to post Share on other sites
