Dude is it running already?

Michael

Well

[Diederick/DVK]

not yet. looks like i've got an issue to sort out.
will post when it is running 

[Peter]

Hey Diederick,
are you sure about the 0.3 mm endplay?
what i read is that 0.004 - 0.005 " is ideal, thats 0.1 - 0.12 mm 

[Type1/DVK]

around 0.12 is best, i've got a bunch of shims if you need them.

[Type1/DVK]

Almost ready....  (first few sec's the ida's bowls are not equal filled)

Mageto and finetuning and its almost done.

''hangs'' nice on the gas
(ps: that's me in the vid)

[Nico86]

Good news!

[CHR!S/DVK]

i would name it a break-through!

cheers for the running 1915!

[Type1/DVK]

Now with Joe Hunt Magneto!

Bit of 2nd gear action, remember to keep a bit of low cylinder pressure to set the piston rings. More to do, more to come!

edit: something went wrong, no idea why i quoted my own post...

[Nico86]

Cool Died!

[Diederick/DVK]

merci bien! 

[Diederick/DVK]

not too happy with the engine yet...

- i'm having near to 4 bars of oil pressure with a cold engine. 20w50 Brad Penn oil and 30mm oil pump.
- the engine is sweating a bit on the lower half, i'm thinking the breathing isn't sufficient. currently i have 2 hoses (magneto stand and oil filler) running to a breather box above the gearbox with a K&N filter on the third fitting... but the piston rings haven't "set" yet either...
- and a bit of a leak coming from the oil pump cover and oil line running from pump to filter. gonna try and fasten it a bit more tomorrow.

lastly, this engine gets hot quick. i still haven't really driven it but after about 15 seconds of idle you can feel the heat rising, i may be exaggerating but it's my first build and is this normal??

any thoughts are appreciated. i just hope i'll make it.

[Nico86]

What oil cooler are you using Died?

[Jesse/DVK]

Stock at the moment.

The heat is normal with that type of exhaust and larger engine. Just run it you will be fine.

The 4 bar should be checked with a good gauge as you didn't trust the Porsche gauges..

Here is my 4 cents:

1) High oil pressure is good. No worries. Well proven oil but why no try a thinner oil?

2 and 3) High pressure will force the oil out. Fix you`re breathing and then check for leaks. Rings that are not set will also increase the pressure. How big is the in and out on you`re "breather" box? It is hard to improve the breathing capacity of a standard engine and if possible I would remove the box above the gearbox.

4) The heat will rise as soon as the engine starts. The question is: how hot is hot? Oil temp is one thing, head temp is something else. A poorly tuned engine can also run hot.

thanks for the advice, fellas!!

i checked the pressure last night with a 52mm VDO gauge: identical results. i just poured in 40 euros worth of Brad Penn oil. can't afford to see what another brand's 15w40 would do. anyway, i suppose it's better than too little pressure

cooling is a stock brand new oil cooler, although I've got the external 72 plate cagero cooler mounted already. been thinking of plumbing in my cagero cooler and bugpack thermostat. but seeing that jesse had no high oil temps at all with his very similar 1915, i figured that could wait and i could focus on more important issues.

the engine is properly tuned luckily, accurate jetting, timing and valve lash. though i painted the header with VHT flameproof so it could be that that stuff still has to "bake" a bit, hence a little smoke coming off the header.

the breathing is insufficient I suppose, but i got something else coming up to replace it, so this will have to do for a few weeks only.
it's that tiny whiny bugpack box with 2 hoses (magneto stand and oil filler) and a K&N filter. i could install another similar box with 4 outlets (my brother's) and hook up the 1-2 valve cover, but what do with the 3 unused outlets?

i suppose i am still a bit of a noob when it comes to these issues, and a bit careful after spending this much over the last 4 years. nevertheless, i do intend to make the drive down to chimay and see where that ends, either back home in the garage or on the hard shoulder, haha  

thanks again, please keep the posts coming

That box can hardly be called a "breather". So to get it straight, you have the original, little oil filler box with the hose routed to the BP box? Or is it just going to mother earth? And on top of this you have a hose going from the fuel pump cover to the same BP box? Please do a search here on The Lounge before you decide to breath from you`re valve covers.

I would get rid og BP and throw it as far as you can so that you`re sure you will never find it again. Then use a hose from the fuel pump to the underside of the original oil filler box and increase the outlet on the box to 20+mm and put a filter on it.

I think the cooler is good too. But maybe a 30mm pump is too much is you don't have an external cooler I'm gonna use a Berg 26mm on my 1904cc (stock cooler too). Or you can maybe use the oil pump cover with oil pressure relief spring.

[Nico86]

And about the VHT paint yes, when I baked the parts in the oven there was some smoke and "burnt/hot smell" in the begining. Then it dissapeared in the end of the baking.

[Diederick/DVK]

The 30mm pump should be fine, I got it from Jim Ratto who has been running them for years and years on his own engines. Thanks for thinking with me, but you're right a 26mm would've done well too I suppose and a pressure relief is a nice add-on!

Good to hear, I only put on a thin layer as my brother nearly finished the can on his header  

[Diederick/DVK]

Kalle, I sent you a PM.

Yet, I wonder why do so many people get away with that small box I'm supposed to throw away. Even with 2+ liter engines. Why can't I? haha!

[Diederick/DVK]

can anyone help me on this one. i took the IDAs off after the first few 800km and i noticed they were dirty.



there seems to be fuel leaking from the float bowl. at least i could clearly smell fuel, even though the float bowls didn't contain enough fuel to start the engine. perhaps the thread cover (part # 23) needs a new copper o-ring? but what about the thing in the middle of the pic above the pump lever?



oil residue on the bottom of the carbs...

mind you the carbs were cleaned ultrasonically, i think. so all the grease etc came about during the first 800 or so kilometers.

[Type1/DVK]

fluel/greasy is normal, maybe change that alu-ring and your done.. Wait and see after 2000km's THEN they're dirty

[Jesse/DVK]

Took Diederick's engine apart today because of a bolt that came loose of the Jaycee magneto stand and dropped into the case!



Found the bolt but unfortunately it has damaged the cam gear. Is it still fixable?

[Diederick/DVK]

Just to clarify. The bolt that came loose is one of the 2 bolts that bolt the vertical piece to the fuel pump block off on the Jaycee magneto stand. I've explained this to many people since this summer. Of course the Jaycee magneto stand was properly assembled but that one bolt just rattled loose somewhere during the 800km I did during summer. I suppose I should have used loctite...

I'm glad the bolt has finally been found.
Unfortunately, my magnum cam gear has been damaged.

Can anyone help out?

[Harry/FDK]

I'm diggin'.
