I agree with Mr. Chuck, fantastic job!

When I was a teen I used the spare time teens have wisely. I used to buy crate bikes that nobody knew about or had long forgotten. Jawa, CZ, Penton, Bultaco, Montesa, Ossa - and make them absolute museum pieces. New or better than new. Then make a fitted cover and my mom would embroider the logo and sew, my dad would waterproof them. Buyers came from far away and NEVER haggled on price. These machines are works of art and should be treated like precious treasures and rode into the ground like ya stole it. When you ride one and it gets the wind in your face and you and the bike become one and you find your pace, that happy place where the two of you just tick: replace THAT! When you look deep into it's paint work so rich and deep and flawless...see the sun blinding you off the chrome...You jump back on it to ride it LOTS more! It's a love affair, man. I could NEVER be happy with factory new being "good enough".

I've watched every video of your jawa tuning, this work is absolutely brilliant and well done , in each detail. I'm a two stroke lover since childhood and i completely agree with what you have done. Decreasing crank weight, converting the piston port to reed valve... everything made respecting the original look of the Jawa. Very pleasant to watch till the end, i hope you make more videos for a good listening to this singer! It runs like later ari-cooled cross with many rpm and a lot of torque at low. As i expected you had issues with gearbox and clutch system, but you solved brilliantly. I've recently got a spare cylinder for my californian 250 and i was thinking to work on the cylinder, not something so radical but definetly they have good potential. Still thank you for sharing these brilliant work, have a nice road :)

Просто великолепная работа👍 Парень, ты просто гениальный мастер, прими искренние слова с уважением

As a fabricator and welder of 30+ years I can truly appreciate the skill and craftsmanship in making these. Excellent job, I bow down to you. Beautiful pipes. In a future project I suggest tack welding your entire pipe together then filling it with a constantly replenished supply of argon (back flushing). It will give a cleaner weld on the inside and a stronger weld for resistance to metal fatigue.

About 12 years ago, I designed & built the entire exhaust system for my 1988 Jawa 500-826 500R Mk.II. I ran the numbers and deliberately made one of the headers 8cm. longer than the other, which causes the Rotax 504 engine to ease into "coming on the cam" at 6,000 RPM, fully light up between 7,000 to 9,000 RPM and rev out at 10,000 RPM. The silencer is a cut shorter 638 silencer (for the megaphone effect) with the innards of a Micron race can with added adjustable backpressure tubes (because 4 stroke singles hate straight through pipes / need backpressure). Top speed was up from the strangled stock 95 MPH to just over an indicated 115 MPH.

@Quiet.Light.Engineering

For initial spots I used below 10 A. For weld I used settings between 25 & 35 A. I was told professionals use higher power but well much faster, which reduces heat affected zone and results in better weld. I’m hobby welder!

Absolut liebevolle Arbeit bis ins Detail, Hut ab! Mich würde kurz interessieren, für welchen Drehzahlbereich (ca.) der Auspuff für die 353-er gedacht ist? Bei den normalen (ungetunten) 352, 353, 354, 360, ... Motoren ist ja eine schwere Kurbelwelle drin, die keine hohen Drehzahlen (über 6000U/min) mag und verkraftet. Gruß

@Quiet.Light.Engineering

Жыл бұрын

Danke. Der Motor dreht mit kleiner Kurbelwelle (siehe anderes Video) munter bis 6500. Immerhin 1500 über Standard und völlig ausreichend. Die Größe und das Gewicht der Kurbelwelle sind nicht unbedingt ausschlaggebend für das erreichbare Drehzahlniveau. Der umgebaute Motor würde mit der originalen Treckerkurbelwelle genauso hoch drehen, aber länger brauchen dorthin. Die Haltbarkeit wäre ggf. auch reduziert.

This is not the case Sir. For example none of the programs I know works for a twin exhaust. You can only try to halfen the area (not diameter) the program suggests. I tested several things and the product in the clip is a mixture of everything. Plus the exhaust is shorter as it needs to be - for optical reasons.
