Tomos Street Tracker Build in collaboration with Tomoshop! This video series is sponsored by Tomoshop.nl! Shop for the biggest assortment of original, tuning and replica Tomos parts here: bit.ly/42FxoAm
Vintage meets modern in my journey to create a Street Tracker moped. Street tracker motorcycles have a rich history that emerged from the world of flat track racing and custom motorcycle culture. Flat track racers competed on lightweight, stripped-down bikes with simple frames and high handlebars for better control. The street tracker style began to take shape during the 1960s and 1970s when enthusiasts started adapting flat track race bikes for street use. These modified motorcycles retained the minimalist and functional design of their racing counterparts, while also being adapted for road riding. The style represents a blend of vintage aesthetics and modern functionality and performance, capturing the essence of the open road and the spirit of urban exploration.
Inspired by the street tracker's fusion of vintage charm and modern edge, I'm building a unique Tomos moped that contains these elements. A lightweight frame, wide street tires, raw two-stroke power, agile handling... Stay tuned as I bring this vision to life with the help of Tomoshop!

@danijuggernaut 9 ай бұрын

Cool, i did the same job in June. 74cc Airsal reworked on a Puch 4v. Allways check the cylinder piston kit like you did. Nothing is good by deeper checking. The Airsal did not open fully the transfers with the supplied base gasket. The exhaust timing was only 175° (just ridiculous). By grinding the exhaust port 1mm for longer opening time and cutting 2mm the piston back for longer admission time. I have now, 185° exhaust time, 175° intake time. This timing is for high rpm and works only excellent beyond 8500 revs up. Listen my dear friend, you did a too small piston ring gap. A too small gap is the reason of the most seized total failure of the piston. 0,15mm is far too small!!! The rule says that the gap should be 0,089mm for each 10mm piston diameter. Your gap for 70cc should be about 0,3 to 0,35. I have on mine 0,41mm. 70cc is not a joke, more power, more heat, the most common failure is that the piston rings touch by heat dilatation and the engine gets seized. Another question to you: Have you checked first the timing before you started machinig the cylinder? You should first check transfer opening and choose the right base gasket in thickness. From there on, protractor and check. Another thing to blame on Airsal, the supplied gasket where worthless (0,3mm base, 0,6mm head). Now it´s excellent, i have 0,5mm base gasket and a 0,4mm head gasket and so, a 0,8mm squish.

@Tomology 9 ай бұрын

Thanks! For the ring gap I used a general rule of bore diameter *0.004mm. I don't have a 0.18mm feeler gauge so I made sure the 0.15mm fit easily and the 0.20mm fit tight. I think 0.41mm ring gap for this 70cc is too much and will cause excessive blow by. Yes, I checked the timing before I started machining the cylinder. I also have the experience that generally the supplied base gaskets are incorrect. Good to check them too.

@danijuggernaut 9 ай бұрын

@@Tomology Yeah man, they lie to us. All tuning manufacturers. 0,4 is good for my 74cc. Your 70cc need at least 0,3mm. Believe me, don't destroy your engine. Drive aircooled cylinders have big tolerances and a little performance is sacrified due to this generous gaps and tolerances. In the other hand, they are indestructible tough. Mi Airsal pistonring came with 0,25mm. Not acceptable in my hot mediterránea weather. Believe me, 0,3 gap. I screwed my baby Up to 15000 rpm and no overhead issue. Just thing, you will have to open your engine frequently for inspection, quick you will detect any failure before total breakdown. Cool Cranckshaft bearings, they look solit. Puch L17 are not so good, serious worn out above 13000 revs. Cheers mate enjoy your Moped.

Please be careful! Petrol is indeed a wonderful cleaning and degreasing agent, but it is also very dangerous to use for this purpose. Here in the USA, if the Occupational Safety and Health Administration caught a shop using petrol as a cleaning/degreasing agent in an open container such as you were using, that shop would face a very, very large (tens of thousands of dollars for the first occurrence) fine, especially if it was being used indoors.

Please don't drill toward your hand. My old boss told me about the person who was drilling a car wheel-well, when the drill went right through...his hand. He went on to mention all the meat caught in the flutes. For decking the block, a piece of glass such as tempered glass from an old scanner makes a nice makeshift surface plate. If you wet the sandpaper, it will stick like magic. A drop of dish-soap makes it slide nice, well nicer, anyway. Also the water keeps the sandpaper clean.

@Tomology 8 ай бұрын

Hey man! By comparing pictures of a 74cc puch/tomos cylinder and the mc80 cylinder (both have a bore diameter of 47mm), you can see that the width between the cylinder studs is different. The studs from the mc80 seem a bit wider spaced, so I guess you can't put an a35 cilinder on it. I'm not 100% sure though. Maybe someone can confirm it for you!

@@WokeYtube no, I can't. but officials can. it has been done before in the Netherlands with different kinds of mopeds. the tyres are highway rated to a max speed of 150kmh. the brakes need to have a certain braking distance.
