1600 mild street engine buildup

[Tony Z]

that might work Sarel. Problem in SA is also that pretty much NO-ONE knows wtf mo-di (MoS2) is. And spending time with a sales person just ends up with you trying to explain it as copper slip or graphite paste but made from moly. And then they say "well if you want graphite, then get graphite" (quote from Bearing man sales rep).
Maybe I'll try to track some down and see what its all about.

Someone needs to convert the local importer of TORCO fuels to also get the Torco assembly lube stuff. Had a look at the MSDS for this stuff, will try to import some. Will do one small tube and hope it gets shipped Then if successful I may bring in some more for sale.

Its been a while since I posted an update, managed to get a bit done today set the crank endplay and fitted the flywheel I still need to torque it up to specs I think I will take it to Dave R for that as I dont have a torque wrench that goes to 400+ Nm.I also dismantled and cleaned the solex 32-34 pdsit carbs I will be using and started making the carb linkage rods.
Hopefully I can fit the oil pump tomorrow and get a few other things on it

[ZeroAxe]

Doesnt the "How to keep your Aircooled alive" book explain how to calculate your 400Nm torque and use a barge-pole to tighten the flywheel nut(that is what you want to tighten, right?) ? I am in too much of a 'friendly' note to check it myselfmaybe I should just go sleep it off!?)

[Edmond]

Got the flywheel nut torqued up today by Dave R and Shaun at Flat Four Racing, that torquemeister tool makes it look so easy, gotta get me one
Oil pump was also fitted today next on the list to do are the cylinder studs,barrels and pistons then the heads hopefully I can do a bit more on the engine tomorrow

Here are the pics of the full flow mod on the case as well as the carbs on their shiny new ICT manifolds[

hi ithink you should speak to dave and try fitting a set 36 downdraught delortos on your motor which in my case i fitted it on standard 1600 and you can realy feel the difference for tuning these carbs and jetting is like a walk in the park. tell me where are you going to to get parts for your carbs should you need it which you definitely will like mains venturies airjets did you ever gave it a thought .you will need to this seeing that you up the motor

[Edmond]

Already got new air correction and main jets for the carbs, SP carbs in JHB keeps all the spares for these carbs in stock and I make the gaskets myself
The carbs are set up according to good advice from a member on this forum who has lots of experience with these carbs
I would have got 36 Dells but unfortunately the finances are just not there but I can always add the dells at a later stage so no big deal

[Edmond]

Got a little bit more done on the engine checked the deck height its 1.3mm so the CR works out to about 8.2:1 with the 1mm flycut on the heads which should be ok with the "Engle W100" grind cam.
Also spraypainted the cylinder studs silver even though you won't see half of them but its a nice touch.

Stripped the heads down to bare ones to get them ready for a mild port job noticed a few of the guide bosses got cracked when the new guides were installed hopefully this isn't a big deal
Also gonna get a set of Chromoly retainers and hardened keepers from Dave R just to be on the safe side as the single hd springs I am running seem quite stiff and I dont want any valvetrain failures from using the stock keepers and retainers

[Edmond]

Got some CB Performance Chromoly retainers from Dave Rowley, also got him to drill and tap my intake manifolds so I can run a balance tube on them for some reason they came with the balance tube port bosses but they were not drilled and tapped.

Gonna hire a die grinder for this coming long weekend so I can finally give the heads a mild port job then its downhill from there

[Dutch_Diver]

Nice work!

Where in Cape Town are you. Let me know re the die grinder - may have one to lend you for the weekend! May just save you some bucks (if you interested that is)

[Edmond]

Managed to port one head today but still need to finish smoothing out the ports, hopefully I can get the other one done tomorrow or monday, will try post some pics of my progress

Big thanks to Andy aka Bugandy for organising me a die grinder for this weekend its people like Andy that make this forum the great place it is

[Edmond]

Heads are finished now just need to assemble them, need to modify my valve spring compressor as the CB chromo retainers sit a little shallower than the std retainers so I cant compress the spring enough to fit the cotters the spring compressor hits the tappet cover gasket rail.

Still deciding if i should get a 3 angle cut on the valve seats are just leave them with the std 45 degree cut, what do you guys think?

Also match ported the intake manifolds to the intake ports

[Tony Z]

3 angle cut is def worth the effort

[calooker]

You should have ported the heads when the guides were out , makes life so much easier

3 angle cut is def worth the effort

Yes, well worth it as well as a 30 deg. cut on the back of the valves
