Dunatic619 Posted May 8, 2016 Report Share Posted May 8, 2016 Ok queers it's time for a build thread. Had the bike for years, broke my back and didn't ride for about 10 years. Then all of a sudden I figured I'd dust of my cooter and get back on the horse. Had HJR build it for me. He did a 4ml, real fuggen HR crank, stock cylinder, aggressive mx port, matching case port, shift star mod, pancake bearing, and some other odds and ends. Was going to do a pro-mod, but didn't have time to wait, and I never had a problem shifting anyway. It'll get done next time I split the cases. Here's what it looked like in pismo August 2015. Decided since I neglected this turd for so many years, it was time to do a full rebuild from the ground up. Frame, front/rear hubs, brake hub, sprocket hub, and brake stay will be PC'd candy blue. Color matches pretty well with my fullbore pearl blues. Upper and lower A-arms are chromed along with my Tyson +2 swinger. Dat chrome doe! Various bolts will be chromed too. Started grinding them down. Got a box going for polish too. All hardware from frame separated into bags so shit doesn't get lost. Since engine was out I went ahead a did a leak down. It held 6lbs for 6 min. Next I'm pulling the head and swapping domes. Static compression is at 150 with +2 timing. Bumped the timing up to +4 and with new domes should be around 170-175 static compression. Going to run 100LL fuel, so I might tard the timing a bit. Then I'll run the piss out of it til it needs a new top end and prolly go driveline cylinders. I'm sure I'll have Qs along the way. I've never done a full frame shee before. Done plenty of cars, so although it's different, the build principals are the same. Let me know if I missed/miss anything. 2 Quote Link to comment Share on other sites More sharing options...

Pardon my ignorance on the subject of chroming, but why grinding the bolts?? Quote Link to comment Share on other sites More sharing options...

Dunatic619 Posted May 8, 2016 Author Report Share Posted May 8, 2016 (edited) You got a great pile of quality parts. Looks like its going to turn out sweet, i like that colour you decided on. GUSTO! Thanks man. Hope all is well with you. Love the fact that you are taking care of all the details like grinding bolts before chrome/polish. Thanks for that. Comes from chroming car suspensions. Need to make sure even the nuts and bolts look tits. Pardon my ignorance on the subject of chroming, but why grinding the bolts?? Most of the stock bolts have a little lip around the perimeter of the head. Kinda makes them like a bowl turned sideways. Easy to hold onto shit that gets stuck in there, mud, sand, whatever else you hit while riding. Makes cleaning them out a real kick in the twat. When ground smooth and flat, claeaning is simple. Plus, water on chrome will cause it to haze and look like crap if not cleaned off properly. Which leads to rust. Clean looking. Thanks zilla! Cleans off all the ribbing or markings for a way cleaner look.^^ this all day. When I used to build cars, I would hate when people would drop 5-7K on a paint job, then hit their suspensions with 99 cent spray paint. Dumb shits.

Dunatic619 Posted May 9, 2016 Author Report Share Posted May 9, 2016 So I was able to escape to the garage for 30 min today and remove the head for the new domes. Here's what I found. First, HJR likes his 3bond! But it passed a leak down, so I can't be mad at him. Looks like one of the gaskets was melted/smashed? Normal? Also, how do the pistons look to you guys? Engine has maybe 10 hours on it. Are the pistons supposed to come this high above the cylinder? Also, what everyone thing about the hemi head? It's old a shit, but hasn't let me down. Think I bought it in 2003. Quote Link to comment Share on other sites More sharing options...
ClaudeMachining Posted May 9, 2016 Report Share Posted May 9, 2016 hummmm....That piston wash look lean to me...But i'm not sure....Look little bit weird.... Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted May 9, 2016 Report Share Posted May 9, 2016 The piston will come out like that on a 4mm crank without a spacer plate. You measured how far they come out before ordering domes, right? Either way do a simple squish test after installing domes. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted May 9, 2016 Report Share Posted May 9, 2016 hummmm....That piston wash look lean to me...But i'm not sure....Look little bit weird....Meh, I'd be more concerned about how it is clean in the actual combustion chamber, but building up carbon around the squish profile.

Looks weird to me. it wash the center but carbonise the outside and intake have more carbon than exhaust??? Educate me. Quote Link to comment Share on other sites More sharing options...

Dunatic619 Posted May 9, 2016 Author Report Share Posted May 9, 2016 @ 50: I'll do some research on piston wash. @ tricked: domes I ordered were custom cut from HJR. Old domes were 23cc. New are 20cc. I'm thinking this might be too big of a jump. Planning on using 100LL for fuel. HJR said 165 comp and 4 degrees of timing would be about the max I could run on that. So I think I might switch domes to 21cc. He said with 20cc id be around 175ish. For carbs: 28pwk, 48 pilot, jjh needle @ 4th clip, 152 main.

sheerider11 Posted May 9, 2016 Report Share Posted May 9, 2016 I'm willing to bet that weird wash is from a bad dome design. I'd go elsewhere for domes. Even your new ones. I have a picture of a good wash on a low hour bike. I'll see if I can find it. You can see the ports and the way the exhaust flowed. Yours being all around the band is odd. 1 Quote Link to comment Share on other sites More sharing options...
