Newbie here, question please, after you change the squish according to the spec, doesn't the nicasyl plating goes off and affect the heat of the engine?
Hey mate, setting the squish doesn’t effect the chrome plating at all, however on a well used engine if using thinner base gaskets to tighten the squish clearance isn’t ideal being that the ring forms a ridge in the plating at the top of stroke. Hope that helps 👍
@@makeorbreak2798 Thank you for your reply mate, I really appreciate that. Let me tell you something, you did one of the neatest job on the community, no cap, I believe you can also make decent side hustle income with that skill. Keep up the good work!
This is a great video but this is far from the most powerful 30.5cc engine. You will have some blow back issues with out a reed valve. Piston reeds are usually on average better then case reeds however the 5th port is the key. Crankcase boost port should be milled out and bearing lube modifications and case stuffing should be done. I didnt notice if you port matched or not but if you didnt then that would have needed to be done aswell. Your dome is too small now it needs to be ball honed a bit as your compression will actually fight your RPM. Also your piston would have needed windowing and your bottom sleeve on the exhaust side needed shaving on the sides to reduce friction. HOWEVER this is a very good attempt at porting.
What makes you say piston reeds are better than case reeds? Im currently making some cylinder reeds, about twice as big as the cylinder reed kit you can buy.
@@WikWak That would be good however you have to consider crankcase volume. "Charged air" Which is the term for air fuel mixture that is sent to the cylinder is lessened by case reeds this is because of its path of travel which is why case reeds suffer from blowback issues more often then cylinder reeds do. There is much less of a path for some of the charged air to make it into the Cylinder getting rid of more of the "10% spent air" which is the term for whats left into the cylinder after its charged "usually its 10%"IF there is a large enough 5th port and boost port. you COULD do a 6th port but I personally like larger 5th ports because you get more torque. On average you will get more torque out of a piston ported reed then a crankcase reed. you can contact this guy he has more knowledge in piston ported reeds then I do th-cam.com/channels/_x31PaM77EtK6osT5b3Qqw.html
@@TrooperManaic it ran terrible lol. Tuning was just all over the place, the exhaust port does get uncovered at tdc, but it wasnt really a problem with piston port, so idk what the issue is. Id say crankcase volume is still good, its got a stuffed crank and i designed it to have minimal extra space
Hey mate thank you, this is a piston port not a reed valve intake i prefer pp’s over a reed engine in a losi 5ive t reason being is i have designed an air filter which only fits on the piston port engines due to carb sitting closer to the motor than a reed setup. And your spot on 👍 compression is too high but i want to test it first so we can see the gains (max rpm) after cutting the combustion chamber, cylinder is matched to the case this was important as the transfer as wide as they can be 👍
@@makeorbreak2798 totally understand... Can't knock a guy for asking. .. anyway I subbed ! Your work is some of the best I've ever seen . Wouldn't mind seeing a video explaining how you learned all this stuff .
@@donniep90 Thank you 🙏 I appreciate the kind words, i will look into that, 2 strokes have always been a hobby of mine so i have just learnt over the years. Thanks again and thanks for the sub
@@jotech1000 sorry mate theres like 6 or so including mounting, if you have got cnc or router it isn’t to hard to figure out just remember the piston pin is offset .5mm

Great video. Do you have a link for the lightened piston pin?
Is it can use for brush cutter?
Buenas , para que son los tapones del bulon piston gracias
HI, amazing job, did you have weighted the ignition flywheel, how much weight did you have win?
Hey mate I didn’t weigh it, so i am unsure sorry
Hello. tell me about your balancing stand and about the lightweight piston pin, please
Its a du-bro prop balancer, and the wrist pins are from heli-world 👍👍
world-of-heli.de ?
@@yp4525 sorry mate i think its shut down now 🤦♂️
Nice.
Where did you get the lightened piston pin from and I noticed it's a plug instead of clips to hold into to place
I got the wrist pins from heli world a long time ago which doesn’t exist anymore 👎 the caps i just made them teflon, 👍
@@makeorbreak2798 how can I get in touch with you other than TH-cam

Got a serious question if I sent you to watercooled heads could u port them n adjust the squish for 30cc
Hey sorry mate i just do my own cylinders at this stage 👍
@@makeorbreak2798 ok no problem I've got water cooled twin that I need new heads for but the 30cc r out stock have been for almost a yr

Thank you 👍
How much to build another one 😫😌😅
Hey mate I’m not sure i just port my own 😊 👍
I want you to build me a motor how do I get your information to do that if you still do it
What cnc are u using?
It was a china cnc6040 but i have upgraded the gantry, i think you can see it the latest clip
Nice Work. Meby 5 HP.
Thank you, hopefully about 6hp
