I don't know if that is the case. I just think everyone sees COVID pricing on everything so they figure their crap is now worth a stupid amount. The guys that have skis listed high around here haven't moved all summer, still on craigslist. Benn laughing on two local stock Kawasaki 440's with trailer for $4,500 that are "race skis" and he knows what he has so no low ballers, LOL!!!! GP1300R all stock for $8K. Two 1995 WetJets for $6,500.
Very true I have done really well selling used skis and ATVs for the past few years , in fact probably moving into mostly sales and way fewer repairs next year, if it goes as planned repairing customer skis will become a thing of the past here
If you could have kept this member ,out of your sweet, sweet ,mouth all these years and forums, I wouldn't even know you existed. Must suck. Those urges
There are probably many other forums more suited to your Ghey fantasies than this one, maybe check one of those out instead of dragging your fetishes into this thread about cylinders.
Yeah I am not nearly as cool as that guy 1
Same place you were asking about porting 1100 Yamaha cylinder and were turned away ? Those motors are completely different than any other. So maybe a rotary valve engine is what you should be copying ? Oh wait it already out there. They don’t have parallel wall transfer ports. Ask ebrig about the “risk vs reward” On a project like this. Not very profitable. Please educate us on the specifics of this cylinder so we can understand it’s performance capabilities. BMEP projected numbers,port area ratio or maybe some actual real world tests. Designs on the computer don’t always prove true in the real world. I do Applaud you for trying but please don’t just use the pv idea as being superior. The coated cylinders myth comes into mind.When they were dyno testing with the two stroke gp bikes they found a power increase on cast pistons over forged pistons. Forged pistons can handle deto better but the cast made more power on the dyno.
This was straight from Jan Theil and Frits overmars who were responsible for the 54hp 125 rsa Aprilia engine. Im probably going to listen to what he says as he has the runs on the board. There is numerous links to this but here is just one of them

Yup I was asking questions I ask a lot of questions trying to increase my knowledge, i have no respect for people who can not ask questions, anybody who thinks they know it all is a waste of space and just pure hot air. I also have no respect for people who come on a post trying throwing out fancy words trying to sound smart. If you want to know if some one is smart see if they can actually explain it in a way that people who don’t know understand. If you can explain it in a way that normal people can understand you then run the chance of not only teaching but also getting questions back. People who try and confuse you are doing that so you will not ask a question and thus find the limit of their knowledge. The software I am using by the way to develop the cylinder is the same one a lot of two stroke engines are developed on, https://vannik.co.za/EngMod2TDetails.htm
There is still a good group 9f guys here...
but so few of them ride!
