Swartz95 1 Posted June 7 Needing some help figuring out if there are any thread inserts I can throw in to avoid getting a new head. I'm kinda ignorant and don't have tools to determine what inserts I need if feasible. Inserts I need would be for 13, 12, and 10. Here is a website if you need any more information on parts and such. https://www.partzilla.com/catalog/honda/atv/2007/trx400fa-a-fourtrax-rancher-at/cylinder-head Share this post Link to post Share on other sites

All three of those appear to be 6mm. If you do have to drill them out helicoils will work Share this post Link to post Share on other sites

Swartz95 1 Posted June 8 (edited) Shadetree is correct. Bolts are not broken, just damaged threads. I think all these are the same pitch. So something like this? M6x1.0 https://a.co/d/a4YiUn5 Edited June 8 by Swartz95 1 Share this post Link to post Share on other sites
