They Race them.... because there are More than One of them, of course!..

The Spanish village of Betxi hold a cultivator race around the village as part of their annual festival.

Machines are limited to the 'original' fitted engines and the Bultaco's are quite tuneable and popular

I dunno Dave, I think it looks like a bit of fun.

Thats pretty bloody good. Buggered if I would want to be on that thing at 100 Kph, race anything.
So long as its got a twostroke on it.

I'd like to try and make some Peek piston pin caps.

Suggestions for securing caps to piston?

No circlips, the caps snap into pistons circlip grooves. Does this sound like a good idea? Piston pin should stay secured this way, won't push caps out?

Removing caps when performing a piston change. Drill hole in cap, punch other side out?

Sounds strangely familiar Jonny .
Kidding aside, in case you really missed what I posted about the subject, you can find some pictures (and a lot of other stuff) here:https://jmp.sh/uXqkAr9
No need to drill one of the caps in order to remove them. Just punch a tiny hole in one of 'm and apply air pressure; then the other cap will pop out, after which you can poke a screwdriver through the piston pin and push the first one out from the inside. Both caps are re-usable; the tiny hole won't matter.

There's something on my mind that's constantly got me scratching my head. Spark plugs. I see over and over on various online communities (2T & 4T) with experts stating their 'opinions' on how to read a spark plug. Everyone seems to have their own variation. It usually comes down to... read the color here, measure the smoke ring there, count how many threads, etc, etc. Of course, this is usually in reference to the plugs telling you if the engine wants more or less timing, fuel, etc. This seems bass akwards to me. Shouldn't the dyno tell you what fuel and timing the engine wants? Once that is established, maybe check the plugs and make sure they aren't overheating, melting, fouling etc.? Stated another way... if we are looking at the burn mark position on the bend in the ground strap, couldn't we change the position by choosing a different heat range plug and not even touch the tune?

For example....Let's say someone brought an engine in for tuning, with completely unknown history and no spark plugs. What is the thought process to tune the engine and specify a spark plug? What specific parts of the plug are we looking at and what are we looking for?

Thanks in advance!

Hi Frits
do you know where you can buy piston pin plugs similar to the ones as per your photos
regards Richard

[Frits Overmars]

Nope. A friend used to make them for a while, but he is too busy expanding his empire. That is why I posted the pictures and drawings here, in the open, so everybody could give it a try themselves. They're not that difficult to make.

[Flettner]

Haha, Frits, it's a bugger being a know it all, all these questions day after day. But we thank you for your time to answer them, I'm glad some one knows the right answers.
And when you consider the whole twostroke world, we are glad you come over to our little corner. Thank You, we appreciate you.

Thanks Neil, you made my day (night really, because it's 01:28 am over here).
What do you mean by 'our little corner'? KiwiBiker? I'll have you know that Kiwibiker and Pit-Lane are the two open forums that I appreciate the most. I really enjoy coming here.
There's a trick in knowing the right answers: start at an early age, make all the mistakes you can think of, and grow old. And I have to thank my father who let me find my own way, and Jan Thiel who shared his thoughts with me, and a lot of friends with whom I brainstorm over tea (that's emot) and stronger beverages.
I'm a happy camper .

Funny husa, I was looking for the very same stuff two days ago :-)
But an other question, since it is possible to ceramic-coat exhaust pipes, wouldnt it be possible to do the same to the inside of a crankhousing?
My Vespa engines are getting hot as hell...
