some internal engine part questions / engine rebuilding general

[junior varsity]

The other big thing I liked about having the gears lightened by FFR was that there was a fast turn-around time using the gears I sent in - I didn't want to do a core-exchange for the timing gear, as its part of a matched pair of gears, with the other timing gear on the crankshaft itself - and i was taught that they should "stay-together" - be it the matched primaries or others.   Perhaps its not 'required', but whatev - I got mine back and fast too.

If that HP is the same one in Oklahoma, then they are top notch.  I used them for SFL coatings on VW engines.  Take a 1600 VW motor, bore and stroke it out to 2.3L, balance the crank statically and dynamically with the Carillo rods and pistons..  then SFL the whole interior, cam, lifters, everything.

practically doesn't need oil.

I had thought about doing the cams and rockers on the ducs heads as well, then i also had thought about DLC. 

That said, currently all paddles are out of the water for a week or two as things are getting busy 'outside the garage' (heaven forbid).

[ducatiz]

I would do the rockers, but not the cams.  The polished surface of the cam should be fine.

I used POR's aluminum engine enamel on my CB750 after hearing that the rattle can (VHT) paints do not hold up well on exposed motorcycle engines. I have used it on auto engines and it seems to hold up fine on them.

I was hesitant on spraying the POR enamel, because after I mixed it the metal flakes didn't seem to distribute in the thinned paint. After I sprayed it, it looked like shit, the bright silver paint was littered with black streaks and spots. However, by the next morning the metallic flakes had evenly dispersed and it was a wonderful raw aluminum color. They advertise that you can brush it and I bet you could. It seems to self level and even out as it dries.

I have noticed that it has slightly darkened deep in the fins, but its tough as nails and I would use it again. The picture below is after it had dried.

G'day j v.
How's the build going?

How are you going to retard the ignition 2-3 degrees on max advance with hi comp pistons? You gonna use different ignition boxes, move the pick ups or go the Igniteck?

I've got JE's in there and are running the Igniteck at 34 max advance from 6000 rpm with 98 RON (95 MON?) I had previously moved the pick ups and that worked ok, although the lower rpm operation is much smoother with the Igniteck.

[junior varsity]

Haven't gotten much further on progress right now - figuring I'll have to figure that out when I get there. I have a set of the DP 1.1 ignition boxes to try, as well as the originals, and looking at either ignitech, or seeing what alternatives there might be (such as Silent Hektik or AS Uotani)

You back in the garage yet?

[junior varsity]

Negative.   Working on getting some tools in (ordered a primary gear puller at long last) and still waiting on something, anything, even a status update on my now-2-month-old Pro Italia OEM parts order. (sigh).

[junior varsity]

Still no substantial motor updates.  Those parts that were on order from ProItalia: Still on order, can't get a status on them.  Kind of a lost summer, as I sit and study for the bar 8 days / week and don't even ride the bike that is all put together...


But, I have accumulated a few parts.  The fixer-upper M900 will have lots of "916" parts. Front wheel, forks, ...rear wheel...

Here's the front end, mock-assembled:








IMA billet triples, IMA damper clamp (with insert so I can use a SBK damper clamp, and thus add a splash o' blue to match the blue handlebar), 916 forks, billet fairing brackets, carbon headlight brackets, 916 front wheel, BCM/Antron Brembo full-floating iron rotors, Brembo billet GP calipers - reanodized black with blue paint to fill in letters, RoadRacing carbon caliper coolers (bracket to be re-anodized)...

Rear wheel to match - DUCATI RACING model 17x5.5" rear wheel. SSS on the way (fingers crossed)

Can`t believe I missed this serious carbed build, nice project.



Heavily arguing should mean some hard facts against them.
What were they?

Not so much to add,
shimming rockers you should go for as centered as possible, freeplay max 0.05-0.10mm (both sides together).
What I was recommended.

this is ridiculous; parts were ordered on April 1st, and normally i'm pretty lenient with stuff, wasn't really in a rush, but the clown handling this at PI hasn't even ordered some of the parts yet!  so the motor continues to sit with the case covers off, waiting on some of the most mundane parts: bearings, snap rings, nuts, and the safety washers you bend around the nuts on the gears.   You're thinking "why not order them from somewhere else?" ...because they've still got my $200+ hard earned moto-funds.   I've given up on them and have convinced my wife that her much kinder and mild-mannered demeanor might make things go faster - so far, to no avail: She's calling or emailing every other day with promises of "I'll get it ordered today and send you and update" or "i'll email you an update by the end of the day" over and over again!

so the motor sits, waiting for the august holiday to come to an end (not that the italian's awesome holiday is slowing anything down, apparently some folks in internet sales across our own country take a 4-month holiday of their own), and in the meantime i've gotten the Febur SSS kit with linkage rod and rocker, gotten the offset front sprockets on order, 'figured out' (tentatively) the whole SSS rear sprocket & cush drives setup, mocked the whole thing up with a spare set of crankcases, made measurements and mental guesses at how the LH high-mount exhaust's intermediate pipe could be altered to clear the bulge of the swingarm, and looked at a lot of dirty pictures on the internet.

In addition, I've packed up damn near most of my life (minus the garage) for a move to Nashville, bikes and the bed are about all that's left in Dallas.   ho hum.

meanwhiles, here's the rundown of lightweight spinny parts on the motor:

Veetwo lightweight adj. cam pulleys, DP lightweight layshaft pulleys, VeeTwo Lightweight Oil Pump Gear, VeeTwo Lightweight Primary Gear, VeeTwo Lightweight Driven gear; FFR ultralight layshaft gear, FFR lightened Sprag Gear, FFR lightened flywheel

The offset front sprocket(s) are on their way from a Febur dealer for the Febur SSS, but its currently packed in a box and not on the bike since it will require some modification to the LH side intermediate pipe for the highmount exhaust.

Front end is pretty clean: 916 forks and wheel, BCM/Brembo full floating irons, Brembo billet GP 2-piece calipers anodized black, a 916 front fender currently, the IMA triples with risers, Ohlins damper, carbon gauge cluster with analog tach, carbon old-school 98-99 Monster front fairing with zero-gravity double bubble smoke windscreen, aluminum fairing brackets (score!), rizoma reservoirs & SBK master cylinders with folding levers, bright BLUE rizoma handlebar, euro LH switch, and replaced RH switch.

Got the carbon long bellypan, underseat side panels, tank buckleguard/kneeguard, seat cowl, ignition cover, rear-hugger for the DSS swingarm I put back on and cf gas cap too.   I'm seriously considering re-welding on the back end so I can mount up the Ducati Monster Cup carbon cafe-cowl (i know its ridiculous huge, but i figure it will be fun and different and i've got the matching street and track versions of the front fairing to boot!)

[koko64]

Some very cool parts there.
That thing will spin up something fierce!
I envy your aluminum fairing brackets as my DP mild steel ones for the DP carbon fairing kills me.
How much lighter are the two piece GP calipers?
As a fellow bike anorexic, I appreciate the sum of the weight loss both internally and externally to the bike.

Ok, had my lunch break, back to work.
