    I have a 3/16" tap I will run in each of the bolts and I should be able to use something to measure bolt depth, these are new OEM headbolts, I still have my old ones as well to measure against.
    Thanks, sometimes life just gets you down and usually wrenching is enjoyable, get some satisfaction of doing the job yourself and other times it just gets frustrating and yesterday it just got to me...

    So I talked to Alex at hammer performance this morning about the problem and theories of what the issue is. Through our discussion I mentioned I had replaced my headbolts with colony, not OEM. So try that first and had success using both long original headbolts. The rear worked just fine so never considered that? Just happy as hell I hit spec and can proceed with confidence. Rockerboxes on
    Apologies for my previous adolescent outburst lol

    Aftermarket parts strike again.

    Slightly different tolerances or what I don't understand it..
    I would have bought OEM originally but didn't know about ronnies. Someone referenced them on here for a part, it might have been you VI, thank you or thanks to whoever it was...

    Brilliant! You should have mentioned the aftermarket parts though; it's an obvious place to look first.

    Glad you got it all sorted... now go and ride, erm, madly!!

    Cheers... Paul

    Sounds like the front piston doesn't have compression or rings got screwy? All seemed to go together okay .. I don't know

    I think I gotta find somebody local to take a glance at it. Guess I shouldn't be surprised the way I had to muck about with the front cylinder and I don't know how much you can play with it and still have compression? Maybe try and get a new close out 1250 from hammer and start over? Lol

    It’s not terribly hard to break a ring. But that sounds more lifter/rocker in the short video.

    I wish ya luck.

    Thanks I'll need it ha.
    Brand new s&s premium lifters in there, pretty sure I installed them right. Maybe a rocker issue too I don't know but front cylinder wasn't firing or lost compression, something..

    did the lifters pump up with oil? Did ya soak em? I dunno what the protocol is on a sportster but on a small block I soak em overnite.

    I soaked them overnight although it was 1040 not 2050, didn't think that would matter. Didn't really get check them, just dropped them in but seemed pumped up installing everything

    Slide the top rocker box off and check to see how much play is in the pushrod. There shouldn’t be any play, but should have so much pressure that you cannot spin the push rod. This should be done with both valves closed. Could be that the lifter didn’t pump up but this should tell ya. I had that one time on a sporty. Doesn’t take much to clog one and stop the oil flow.its hard to tell in that closed space where sound bounces around but it doesn’t sound like piston issue.

    Typically parts store will have tool loan program where you can get a compression testor and run a test on front and rear cylinder. That will tell you if you have a ring problem.

    I'd still do a compression test. Always a good idea after a top end(or cam chest) is put back together. Takes no time at all, and very telling, if something ain't right.
