Grew another wild hair'n pulled the mid apart. Very interesting tuner: Think I might use it after all. Probly wind up plugging or somehow covering the additional holes that were drilled. Cuz I bet the sob is loud enough without em?

Good news! My boy "Dago" says he can put the holes back where they belong. Just how he intends to do that is anybody's guess. But he says he can do it.

I'm glad I pulled this motor apart before running it. With the exception of the case halves & rod bolts. Stuff felt loose to me. And they didn't use any locktite or thread sealant?

Ah well. Hey Jerry, I faithfully numbered the rod caps. Then haphazardly pulled the pistons ... Not to worry. Got em all sorted out now. Each assembly weighs 1220 gm btw. Perfect.

Discovered yet another use for my beloved 'Pearl Disc':

No need to monkey around with dangerous razor blades scraping that last lil piece of old gasket material off ...

Well Mike picked up the block today. Says it's no problem to put the holes back where they belong.

So ... I started putting the '77 mid together. Sadly gaskets are 'unavailable' for this particular tuner assembly. Hence the RTV.

Gotta wait a hour before torquing the bolts the resta the way, but I hope to have it back together tonight.

I've got to find where to get Pistons like those. I'm going to need at least one new one for my 'up block. Also what's up with the inspection cover and manifold differences? My '79 is standard type and my spare '88 block has hoses and tiny nipples in places all over the intake and inspection covers.

Also can you shoot a ton more pics of anything that was modified or unique to the bubble back modified block.

I love that disk idea for cleaning gasket material.

V153 · « **Reply #45 on:** October 15, 2014, 04:53:55 PM »

The idea is the teflon coating eliminates the need for extended break in period(s). Though I don't think I'm gonna rush out'n test that theory ...

The earlier manifold doesn't have lugs/bosses for the later shift & carb linkage. Nor does it have vents.

Inspection covers don't have the multiple bosses for mounting rectumfrier, solenoid, etc. And they are unvented as well. The vents are said to improve oil distribution. Also claim to make it idle smoother.

Re Bubble-butt. There's not much to modify other than chopping out the exhaust rail at the bottom of the block. Note you don't absolutely have to do that, but it's posed to be good for at least 5 hp.

Ya the beauty of a "super-fine" pearl disc is it's hard to eff up and take off too much material. I'm not sure it's even possible with that grit. All it does is polish. You can still see the factory tool marks after yer done.

Yo Fuzz. Being '79 & later your stuff should interchange without too many headaches

Fuzzbutt · « **Reply #46 on:** October 15, 2014, 06:06:35 PM »

I'd like to figure out what you mean by the area I need to chop out of the exhaust area of the block.

I love pictures

I have teflon coated pistons in my Yamaha sled and it didn't require much of any break in. Was revving 8300 after about half an hour of driving. I eventually put enough clutch in it to settle the shift out RPM down at the power peak of 7800. Even at 9000 + miles my twin is strong. The bump in compression and lower rotating friction makes a difference. Especially in a motor with some wear the skirts slap the bores a bit and rob power.

Found Carson reeds for the "sport" modem for the V4 on eBay for $80.

I'm wondering if I can do the newer intake and newer side covers but still run the older style carbs and fuel pump. I'm worried about not knowing where all the extra plumbing should be going. Looking at a rats nest of the "88 88 I have no clue what's what. If I go the new route I need a lot of things to get the priming system complete and I need a replacement float bowl and likely a set of bigger jets to feed my increased appetite. I have the newer single CDI but the timer base I have is shot (bubbles in the windings so bad I can't fit it on the crank snout). Not sure if I would want to go the new electronics route since my power packs are fine. I don't think I have all the newer shift/carb linkage.

Well we got the drilled Franken mid assembled. Trim actually works!? Alls I need now is a powerhead ... Hopin to get my block back from Dago in a couple days.

Monkeyin around pre-plumbing the dual pee hole set up. Gonna be killer. Might even have 'em cross midstream ...

75starflight · « **Reply #48 on:** October 18, 2014, 04:13:09 PM »

Glad you found a work around for this little monster. Can't wait to see what it can do once you get it all together!

V153 · « **Reply #49 on:** October 18, 2014, 04:14:37 PM »

Yo Fuzz the block exhaust cut-out looks like so: That particular one is factory cut but you can accomplish the same thing with proper tool(s).

V153 · « **Reply #50 on:** October 18, 2014, 04:41:27 PM »

Hey Brandon I got a deal in the works. Guy wants to swap one of my lowers, and some parts to assemble a mid. That plus a lil cash and I'm into a purty good looking alum trailer. 'Posed to go down mid week. Keep yer fingers crossed.

V153 · « **Reply #51 on:** October 25, 2014, 12:07:43 PM »

Well I'm still waiting for my block. But on the brighter side I should have the aluminum trailer by midweek.

Got a present from Chris Carson yesterday. And Don hooked me up with a OMC dual cable bracket. Decided that was the way to go since hydraulic's a lil outa my price range at the moment. But the dual cable really oughta help combat chine walk.

More good news is it's finally gettin bearable outside so I can get back on the C500 project. Though it is 87 right now ... Won't really cool off til Halloween.

75starflight · « **Reply #52 on:** October 25, 2014, 01:37:47 PM »

Nice score Doug!

V153 · « **Reply #53 on:** October 25, 2014, 03:09:34 PM »

Ya and the best part is the bracket & reeds were free. WooHoo!

I never had a steel one break in one of these motors but I guess there's always a first time. Think I'd much rather chew on a composite one. Though I doubt that'll happen. Chris says these are good for 9K(!?), plus a couple more if'n you cut/square the reed cages. Like 9000 rpm's not enough ...

Fear not friends I have no intention of turning those kinda revs. (Mebbe 8K ...)

Jerry · « **Reply #54 on:** October 25, 2014, 04:16:10 PM »

Chris is the best!
Did he tell you to prop it for 9 Grand?
I'm still trying to get to 6500.

V153 · « **Reply #55 on:** October 25, 2014, 06:34:29 PM »

What I'm told is Don had chit Chris wanted. And a couple sets of these reeds were part of the settlement. Posed to be sumpthin new Chris cooked up for the re-emerging V4 drag class. I figger if'n they're good enough for drag boats that oughta be fine for mine ...

I'm shootin for 6500 or so wot. Might wind up a lil higher.

Jerry · « **Reply #56 on:** October 25, 2014, 08:18:15 PM »

His last words to me was "DON'T LUG IT!" Prop it for 6500 if you run slower that's fine, just don't lug it down. If you prop for 8500, and run at 6500 that's fine Just don't lug it.

BTW
we dumped yer pee today.

V153 · « **Reply #57 on:** October 26, 2014, 07:07:31 PM »

I hope I wasn't the only one to "go" in there. Although in my case it is kinda like anti-freeze ...

Got the new reeds safely locked in their cages today. Lil nerve wracking but it went okay.

The hot rod guys chop material outa the cages & square the rounded openings. (See pic.) In order to force more fuel through the motor. We won't be doing that ... Burns enough gas as it is.

V153 · « **Reply #58 on:** October 31, 2014, 07:30:12 PM »

Finally something positive. Got the aluminum trailer home. Needs a lil tlc but not too shabby. The boat'll easily fit between the fenders so's I hope to set it as low as possible. Should look purty cool.

Plus I talked to "Dago" and he says the 140 block should be ready soon. He was waitin on some fancy schmancy thread inserts.

Now if I can just get my truck running ...

V153 · « **Reply #59 on:** October 31, 2014, 07:58:17 PM »

Forgot to mention. Digging through Ernies junk pile & found these lil gems: 5 deg transom wedgies. Add an inch of setback too. WooHoo!
