Originally posted on intro page but I feel comfy enough with the crowd so I'm jumping into the big pool. Spending lots of time working on my sons atv. Question, had to get head and cylinder surfaced due to warp. He bought with 87mm bore kit without questions. Can anyone help me with the piston/valve clearance. Honda service said .015 to .050 mm. .015 seems awfully close with heat expansion and high revving. Wondering, because I can't find in service manual, can't get answer from kit companies and honda service dept answer just seems to close. Already had one bent intake and don't want another
Thanks for any help

Read your other post. The manual does not give the spec you are looking for. Clay is the way grasshopper...lol good luck

I know how to check it with clay or light spring measuring, I just don't know, with conviction, what the spec'd range should be (I know that cars run .080 and .100 sae and my sons other bike .040 -.065 mm.
