I was told a couple of years back of a method which may apply here....

The timaru based group of car race guys who over many years have had much success at national level, wanted to race a datsun 1600SSS in production class races. They looked at it and said, ride height is way too high...rules say we can't change or modify the springs.
So while the engine and box were out being blueprinted, the car sat on old rims, stuffed full of sandbags - I'm told about a ton weight all up...
By the time the engine was done it sat about 1 1/2in lower - and there were no marks of heating on the original finish of the springs.
Puzzled a lot of scrutineers that did.

Setting the static Sag has a new twist.
right I posted it elsewhere as well, but here is what I learnt 20 years ago.
400 degrees F and a couple of minutes under compression. Bobs your mothers brother.

Looks like a Mitsubishi Gallant, my mum had one new, that color too. Caused quite a stir when she turned up at Church with it, those anal Baptists couldn't get their head around a woman owning and driving a fast looking car, and a car that color to boot to. It was a time when women still wore hats and gloves to church. A Jap car, a lot of the men in the congregation had, had first hand experience with the Japanese in the Pacific.



Mum could drive when she was 15 dad only learnt to drive when he was in his 30's, different times. I inherited it and my kids all learnt to drive in it. Thanks for the memories.

Clearly its a Ratsun like Greg said. My cousin wrote one off, but yes they do all look alike. I had a car once. But only once.

It was a Vauxhall Victor and it looked like, well it looked like a piece of shit. Which was quite an accurate depiction.

not much difients in them 2 cars , mid chrome yellow

Should have bloody known you boys were Datsun folk! I was into Datsuns for years before getting addicted to racing bikes. That car Scott had was a Datsun 160J.

Google image search beeoneoneoh and all of that will have a relation to the fairly successful Datsun/drifting blog I ran for years. The mustard coloured Datsun 1200 truck with the Nissan Silvia SR20DE engine swapped into it was my monster. Suuuuuuch fun. But this has no relation to 50cc race bikes...

lol you have to add the sss to that (-;

Agreed - but buckets is all about lateral thinking and the example i posted is a very cunning example...

The same group of Timaru guys had a Laser Sport which won the Championship run for them which ran for several years and even had David Lange driving one.
In fact they won two years running before officialdom caught on...and changed the rules.
They'd looked at the porting and said - shit those inlet valve guides are bad, how can we improve flow without removing material ?
At full lift there was at least 6mm gap between the spring retainers and the stem seals...so they pressed the inlet valve guides 5.5mm back into the head...
Worked a treat and i can verify from observation that it was worth about 60 meters down the back straight at Wigram.

Most car production class regs now say - original parts - in original position.

Thanks to Roger for having the VHM copied, Kel for designing the insert, Seymour for the CNC magic, my mate Dave for cutting the thread I now have a decent combustion chamber shape, all I need to do is sweet talk team ESE into letting me pop over to make sure there will be no piston clipping the head nonsense and I'll be almost ready for the GP. (just need to sort out the shock , lose 20 odd kilo's and wind back the years to when I was 20)

Nice one. I am starting my 50 assembly today. Its in a lot of bits. Now to remember how that gearbox goes in. And where did the ball bearing go. I think I will make it. Just won't be the bike I wanted to turn up on. We still be fun though.



Will post some pics later today.

you'll make up for it by riding the wheels off it

Hope so. Productive day yesterday. Got the bottom end all sorted. New main bearings at least. Then looked at getting the cylinder timed right. What a mission. It was sitting at exhaust 90 and transfers 110 with no base gasket. Thanks again glen for helping out yesterday. We took 1mm of the cylinder to get to 115 transfusers and at midnight last night I finished porting the exhaust to open @ 83 atdc.

Now to make a pipe close to the FOS dims as possible with what I have.

Did you work out where you were at with the ign?
