Hallo! Wij zijn van Kopenhagen. Wij begrijpen niet Nederlands. We gebruiken googletranslate. Vanwege dat onze syntaxis raar is.

We hebben problemen met onze motoren. Ze krijgen te warm. We rijden lange afstanden. Deze zomer reden we naar Warzaw, Krakau en Berlijn. Hier is onze video.

Maar we konden meestal driveat nacht. Vanwege de hitte.

Heeft u ideeën, zodat we de hitte probleem kan oplossen? Misschien grotere carburateur? Misschien grotere inname?
Waar wil je onderdelen kopen? Hoe de jongens in solexrace stemmen hun motoren?

Alle hulp wordt gewaardeerd.

We hebben ook Engels draad. Het is goed hier:

Many thanks!

Thanks for the answers This is really a great forum and, it seems, the best out there. A shame that our Dutch isn't too good (though there are notable similarities between Dutch and Danish besides the 'D').

Last year, as you might have seen in our video, one of our engines surely ran too hot. And we were thinking: mixing the petrol with diesel, is that actually gonna cool down the engines or won't it just make sure that vapor lock doesn't occur (we're guessing that diesel has a higher boiling point than petrol and therefore a petrol-diesel mix will keep the engine running, though the petrol is getting hot). Correct statement

Isn't it more a way to solve some of the symptoms rather than curing the actual disease, that being the engine running too hot? the actual disease is the poor design of the engine

We have thought about making some sort of cooling device - maybe replacing the clear fuel return pipe with a longer pipe that will 'force' the petrol to be cooled before reentering the tank? If the outlet back pressure is too high you will flood the "carburettor"

Also, as a lot of you have cleverly suggested - making sure that the exhaust pipe doesn't "backfire" hot exhaust gases onto the petrol pipe. For this we're considering constructing some exhausts where the pipes are sealed in a better manner. a rubber hose around the petrol pipe will insultae

When we drove this Summer, my velo really had a hard time, especially when we were driving home from Berlin. It overheated even during the nighttime! First we thought it to be some sort of friction in the cylinder (maybe one of the piston-rings were worn etc.), but had we only known that it might have been the petrol that became too hot while circulating, we would probably have tried some other solutions. We didn't even check if the petrol pipes were too close to the engine, exhaust or other hot areas. make sure to use sufficient oil additive to the petrol for harsh conditions 1:25

Anyways, we're considering getting our cylinders drilled, so that we can use the FS1 pistons. Furthermore we have seen that some of you have drilled an extra channel in your cylinder. What effect will such modifications have on our engines concerning heat issues, durability etc.? only use those for racing purposes using them on a standard one can be detrimental, you have to raise the cylindre by using a foot plate this will affect the crank case compression ratio

Moreover, one of you have designed a nicasil cylinder - is that only a prototype, or will such a thing actually be for sale? If so, when and for how much? This one will be for sale, it is done by a well known racer who started a solex shop to become a professional

And one more - and our last! - question: Do you know where we can get "off-pullers" the devices for pulling off the ignition part and the bearings? We have one for pulling off the rotor. Is it possible to manufacture these 'off-pullers' yourself? yes you can, for pulling the rotor the standard vintage device of the round three holed plate will do, but make sure you use the dedicated flanged nut that will lift the plate ( together with the rotor when you undo the nut
the stator plate can be pulled with a tripod puller when you have the legs at the most ridgid place of the stator plate also explore the website of Ad van Heerbeek

We're sorry to bug you with these many questions, but our minds are pretty set on driving to Moscow - maybe Kazakhstan - and we want to be as prepared as we can get. (And as it seems, more questions will follow!). contact Jan Vennix for his special air filters this will save you the ingestion of debris and excessive wear of pistons, excessive wear will make the engine run hot as well.

Thanks a lot,
