i have pannonia TLT 250, i want my bike flying like this

@Q.L.Engineering 2 күн бұрын

It‘s a bit of effort but it certainly possible to get more power out of this twin port engine. Very good looking bike!

Nice work👍 I have similar plans with my jawa 356.

Hello!

@rosifert 19 күн бұрын

Moc pěkná práce. Tento problém řeším stále. Mám Velorex 250. A je moc těžký na obyčejnou převodovku. Rád Vás sleduji.

@Q.L.Engineering 19 күн бұрын

Ahoj. Možná můžu dát tipy. Moderní převodovky typu 634 je nejlepší nepoužívat. Mají méně kolíků (4 místo 6) na menší roztečné kružnici, což je nepříznivé. Pak je užitečné udělat primární překlad co nejdelší. S duplexním převodovým poměrem 579 je alespoň o pár procent delší. Převodovka se tak trochu namáhá. Pro kompenzaci nainstalujte menší sekundární pastorek. Obecně byste měli zkontrolovat, zda jsou všechny kolíky podepřené rovnoměrně. To je zřídka případ. Možná bude možné vybrat převody, které jsou lépe vyrobené. Používám k tomu „tubing pastu“ nebo speciální barvu.

2 questions, first how much do you waight and second what is the compresion ?

@Q.L.Engineering 23 күн бұрын

Compression ratio and weight is less relevant than low exhaust port timing.

@coffeepisi5173 23 күн бұрын

@Q.L.Engineering i ask bc i have the same problem with a 60cc moped and to start it you need to pedal the trasmision and on cold days my cluch slips or i cant turn it over. I was thinking to do the same thing. Btw the double spark plug make a difrence?

@Q.L.Engineering 18 күн бұрын

Yes, I was surprise to note that the engine delivers a bit more torque with dual ignition on. That might be because of the large bore.

@flyingfish7073 2 ай бұрын

Do the twin pipes work well? I'd have to imagine that you need to make different pipes for the same stroke and displacement engine if it used only one exhaust instead of two, no?

@Q.L.Engineering 2 ай бұрын

The twin port is not ideal, but belongs to the bike. Exhausts should be smaller in diameter but with similar length compared to single port.

@flyingfish7073 2 ай бұрын

@@Q.L.Engineering Interesting, I'm now reading a book on 2t porting and so on, in it there wasn't any mention of how to fabricate an exhaust for a twin exhaust port bike, thanks for the reply.

I did that 2 years ago. Around 35 HP and 47 Nm of torque with modified exhausts.
