Any more details on the carbs? How difficult were they to set up/tune?
Also, pics embedded.

Here's my sunny as featured in... http://datsun1200.com/modules/newbb/vie ... post327570 About time I put up some info of my Sunny. Its pretty much your run of the mill 1979 Datsun Sunny currently in Granny spec apart from... Extractors 2" Exhaust Electric Distributor Quad Motor Bike Carbs Custom air box Interior is in great nick and every thing works on the car (beside fan switch - only works full speed) and the clock. Will fix them once I have the dash out. No rust on body, original paint and wheels. The carbs are Mikuni BS34's using manifolds/air box I made. Having a 34mm bore they have the same cross sectional area as the stock carb but more flow because they don't have all sorts of crap in the bore - plus there's four of them. Being CV of a function they perform great, have good response and are very street able. My plans for the car now is to drive it till I blow it up some how. I did a vacuum test today and I got a steady needle but a little low on vacuum saying late ignition timing (however, ignition timing actually correct) meaning I'm low on compression I guess - rings are a bit tired. So once I'm ready I'll pull the motor and reco the gearbox Plus do a worked NA build. Hi Comp Pistons Camshaft Lighten Pulley (smaller dia. too), flywheel, rods, crank, push rods, Ali. retainers, Ali. rockers Knife edge crank + chamfer/tear drop oil holes Polish valves, rods, crank, combustion chamber, exhaust ports (and grit blast inlet port + tracts) 3 angle valve grind Springs Larger sump Oil cooler Bigger radiator Adjustable timing sprocket Port head New rings, seals and bearings New oil/fuel pump/water pump And more stuff once I remember it... Here's some pics and a Video (would be nice to embed it but I don't know how). Video: http://www.viddler.com/explore/DIYMark/videos/1/ I just love the ITB intake sound - despite somewhat muffled from the air filter and whizzing fan. The exhaust note is pretty good for a $50 muffler and the decel after the rev sounds cool.

As a matter of fact the 1979 Sunny came factory with quad motorbike carbs...what you don't believe me?! You know...grandma had to get to church with some throttle response and intake sound  The carbs are Mikuni BS34's that I got from the wreckers for $60 - obviously a clean up and few coats of paint later they look like this. Setup involved making my own manifolds/air box/modded extractors at work. Tuning is a pain because I had nothing to start with basically and no reference as to what a Datsun with bike carbies should be jetted with. Also these carbs use needle jets and jet needles that no longer exist - they were sort of only made for this carb and the limited motorbikes it was fitted to. However the main jets, air jets and pilot jets are all available these days except the needle/emulsion tube which I had to modify (I drilled the emulsion tubes and sanded needles with a micrometer - hard to get 4 needles within 0.02mm of each other!). But seeing as I was probably going to spend more on jets than what the carbs cost me I just drilled jets in my lathe with a small drill set. Only jets I had to solder and re drill were the pilots - so when I get time I'll order the proper sized ones - I have no issues with drilling the bigger, but soldering them and drilling them smaller to me is a bit dodgy. I also got another bank of carbs for just the jets/needles in it - at $60 a bank, you wont but jets that cheap. Oh and I used BS34's because when I looked at the wreckers these were the biggest bore carbs I could find in a complete set - there were some nice ones of an R1 but they were missing all sorts of pieces. |

CRAB MASTER this thread is about 2 years old and jack of all trades has not been online in over a year. But good luck |
