Anthony Scott 2 Posted November 21, 2023 Share Posted November 21, 2023 I have acquired a Moki 180 2 stroke, recently, it came without the silencer fixing bolts. I am unable to achieve satisfactory security with M4 bolts & M5s are too big. Can anyone confirm the correct size, please? Tony Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted November 21, 2023 Share Posted November 21, 2023 I thought they were M4x 0.7 ? Quote Link to comment Share on other sites More sharing options...
Richard Wills 2 Posted November 22, 2023 Share Posted November 22, 2023 Mine is M4x0.7 Quote Link to comment Share on other sites More sharing options...
Anthony Scott 2 Posted November 22, 2023 Author Share Posted November 22, 2023 Thanks Both. Looks like I will have to drill & tap M5. Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted November 22, 2023 Share Posted November 22, 2023 M5 is a big jump in size for the bolt head. Why not fit a helicoil thread to keep original bolts ? Kits available on Ebay for not a lot of money Quote Link to comment Share on other sites More sharing options...
