G14 engine build

brent44j · 05-17-2012, 04:36 PM

Im needing the torque specs on the connecting rod nuts, cylinder head bolts and valve lash on my Yamaha G14. Also are there any line up dots to line up the camshaft to the crankshaft to put in time. Thanks for any input!

Rod nuts-29 ft lbs. cylinder head bolts-20 ft lbs. Bothe intake and exhaust-.004, when engine is cold. The cam is easy with the hole and mark on the crank, the crank will need to be turned slightly to install the balancer to get the marks, cam hole mark to look like a "V", like the picture.

Glad I could help alittle. Do you know the orentation of the rings? Might also call Tom @ Cartpartsplus and order an advanced timing key, hear it really helps with throttle responce. Be carefull, Tom is so knowledgable, after talking to him, you may have a larger part order.

Good luck with your project.

Yes they have, I still question why Yamaha would have put it in for no reason. I think a member G1-G9 had an experiance with that, might do a search and read up on it.

Got all the parts for the overhaul. Does the cylinder need to honed or does it have a special coating that dont need honing? Also what is the orientation of the rings. I built many car engines but this my first cart.

Yes hone it! The rings need a good surface to seal correctly. Hope you can see the picture.

Got it, I thought I should hone it just making sure. Thanks for ring pic!
