hadi000mah Posted November 1, 2021 Share Posted November 1, 2021 why the progress got slow ? where is the challenge ? Quote Link to comment Share on other sites More sharing options...
arthurmoto1 Posted November 4, 2021 Author Share Posted November 4, 2021 My friend have got broken leg when he was landing on paratrike because of invisible concrete part in grass. That is why it was some delay. But everything is OK with small engine. He is just flying around. It was paramotor race once this year because of COVID and we have got 2 place but it is obvious that we need more power. So the next stage is to finish 250 ccm engine.

arthurmoto1 Posted November 4, 2021 Author Share Posted November 4, 2021 There was a lot of work with 250 ccm engine but it is almost finished now. But I can not attach new photo because of 171 kb size restriction. I'll try later to give you more information. I personally have final race of MotoRallyCupUkraine during next three days and then could pay more attention to this topic.ย Cheers! 2 1 Quote Link to comment Share on other sites More sharing options...

arthurmoto1 Posted December 19, 2021 Author Share Posted December 19, 2021 Hi all! Today we have spent halfday trying to start 250 engine and it is OK now you can see this on video. We have to do some adjustment carburetors work, servo units for carbs and power valve and so on. But we are glad to have good start for now. The frame is from stainless steel for reliability, weight is 29,7 kg with some liters of gas. And there is the previous engine from the beginning of topik with billet cases.ย Quote Link to comment Share on other sites More sharing options...

hadi000mah Posted January 9, 2022 Share Posted January 9, 2022 does it have 2 carburetor ? i haven't seen it before ! one is backup or two are in use together ? Quote Link to comment Share on other sites More sharing options...
arthurmoto1 Posted January 10, 2022 Author Share Posted January 10, 2022 Yes, it has two of them, one is Walbro 37 and the second is Walbro 39. Now we are trying to find the best relation between carbs and powervalve so they have independant throttle levers. But it is definite that one carb is not enough. The engine can not reach max RPM on one carb without help of another. There was one time when the mixture was too lean and the piston was damaged slightly.

arthurmoto1 Posted January 16, 2022 Author Share Posted January 16, 2022 It`s a pity but my friend has got COVID. He has to make tough decision - to stay with us and to finish the engine or to die. I hope he is able to goย right path. Quote Link to comment Share on other sites More sharing options...
arthurmoto1 Posted January 26, 2022 Author Share Posted January 26, 2022 (edited) Fantastic news! It was first fly with 250 engine yesterday! And this thing is SCARY! So much power that we didn`t expect. My friend needs some time to learn the habits of engine. I was going to make video but I have got COVID and feel myself like corpse. Wait for a week I`ll be fine to show you the fly. Edited January 26, 2022 by arthurmoto1 2 Quote Link to comment Share on other sites More sharing options...

arthurmoto1 Posted January 27, 2022 Author Share Posted January 27, 2022 It works like common engine when using one carburetor and with closed power valve. But if you will open the valve halfway it makes twice more power! Quote Link to comment Share on other sites More sharing options...

arthurmoto1 Posted February 10, 2022 Author Share Posted February 10, 2022 (edited) Hi! Thanks God I`m better than before COVID. 178 cc engine project is finished. Everything is nice and we are starting very limited production of this engine for our friends. The heart of the engine -ย https://www.sip-scootershop.com/en/product/racing-cylinder-parmakit-178-cc_PA576080 Three brand new cylinder kits have arrived some days ago. Now we are looking for less expensive manufacturer of crankcases.ย 250 cc engine is a beast and the plan is to use it and to win in championship this year. So we have some weeks ahead to eliminate all bugs from the construction. Edited February 10, 2022 by arthurmoto1 1 Quote Link to comment Share on other sites More sharing options...
