Nice - how many pieces ? Done over formers ?

Where do you get your alloy filler cap necks ?

I use oil caps of car rocker covers , some better than others , the back was the worst 4 bits the rest 4 bits

That tank is such great work... 10 hours .... good job...

I should make a wooden former one day

I should make a wooden former one day

Looking at a couple of Aermacchi tanks which came from Bartels in Northern Ireland, they're welded up from 4 or 5 pressed pieces.
For low volume presswork in alloy, wooden press formers are adequate.
A mate here who has made several tanks for me always does a skeleton former - like a boat's ribs - that he can clamp the pieces to when welding.
He'll be retiring from the port company where he drives straddles very soon and he's probably going to work from home doing tanks.
He welds his using oxy/acetylene....old school stuff.

After many years, we can officially say that Buckets are back in Palmy. Really nice turn out, especially from the Wellington contingent, so I videoed the last race of the day.

The weather was a bit average, my camera is a dog, but anything is better then nothing! Patience was a virtue as riders waited for a 2 hour Kart race to take its course, but I hope everyone felt it was worth it.

nice video

Great turn out from the locals and the wellentonins, thanks for the effort of turning up and making this the start of many hopefully. Also a big thanks to kartsport Wellington for paving the way. I think we all agree it's an awesome track.

That's a decent weight, tweak the little things and it should be a rocket ship.

Thanks for letting me know that my old Coventry Eagle is Kiwibiker photo of the week.

I haven't owned it for about two years, only took that long to get enough votes to win...lol!

Well done on the POW.

Anyway, looking at the new Yamaha R150; apparently it has a variable valve lift VVL on the inlet.
More poke down low...
Simple little system worthy of consideration.

More poke down low? Am I reading to much into this?

Come on Mr Colt Cams. Tell us about cam timing, duration, lift and linkage to variable timing - please....

I want more low down poke. 14Hp at 6000rpm would be great.
