COMBINED CARS + MOTORCYCLES SUPER MEGA :awesome: THREAD

That's the most ass backwards stuff I've ever heard with engine design.

I was assuming two stroke since it looked like there was more oil deposits on the exhaust valve side.

If the rod was friction welded to the crank I doubt you will ever get that out from what skwi just said.


I've only seen friction welds a few times but if it's just ceased should be easier to take apart but still a complete bitch to uncease the rod. all the same parts need to be replaced. Using parts that have been in a critical engine failure like a ceased rod or time belt/chain breakage that was under load at the time of failure is a very bad idea.

 

cease your ceasing or I'll have you seized for failing to seize correctly!

 

Well, the motor is ceased, in a manner of speaking. It is an ex-motor, at this point.

人を馬鹿にするな。

 

The latest image was with the entire engine block and adjacent assemblies stripped off of the bike and they've spent 2 days rebuilding a lot of the bike from new parts, possibly new engine too.

So, what, 7 days on the go and still 300km something.

 

人々を,あなたをだまします
I love living in a world where translators can (badly) provide quick and easy understanding of things I've no real clue about XD

it's amazing how much a difference it makes when you move the comma around XD

 

They made it here! They're running with a handheld IR thermometer so they now know when to slow down. Which is immediately if they drive faster than 50kph. They had their best run thus far getting here because it was like 5c during the night so it didn't heat up as bad.

I suggested pouring water on the engine from a canister but due to aluminium etc. it seems like a very, very bad idea. Also there is no air intake or anything to cool the engine. Also, engine does not produce enough pressure to push oil through a cooling fan thing that would help cool the oil.

They're now running out of their vacation and might not even make it, even though they're going to travel half of the route by train. It's apparently really difficult to find tickets from Germany to France. They found some, but they're now facing difficulties with logistics of getting home in time. Too bad

 

Not sure if anyone was left wondering but my sis made it to Germany with the bike, taking a ferry from Helsinki to Germany but had to leave the bike there because they simply ran out of time. They'll make the final stretch another time.

 

I just drove home along motorway and we were going slower than that!

 

Why do they give me a 2015 S as a loaner? That Beamer engine they stuffed in the new Minis is nasty. Damn thing is gonna get me in trouble. Too bad the 3rd gen looks like ass or I might eventually get one.

 

While I was all "boo-hoo no computer gaems", I did a thing with my bike!



Front is my '07 Kawi Ninja 500r, fully streetfightered with a neutralized rust coating on the tank and front mudguard.

Parked next to a same-year stocker at breakfast the other morning, so thought it would be cool to see a before/after.

Next plans are fabbing up a trunk box to replace the passenger seat section, keeping with the MadMax/ratrod styling by building it out of angle iron and diamond plate, and getting my buddy to make a saddle bag set to match the front tool bag.

 

Now THIS is pretty freaking cool.

Rotary has good power to weight and power to displacement ratios, tends to be very rev-happy and does not build torque at low rpms. Less moving parts means higher RPM limits - usually around 8000-9000 rpm redlines. Respond very well to forced induction. Cooling tends to be an issue - any failure in the cooling system will cause the apex seals (rotary version of compression rings) to fail and sometimes the aluminum sections of the rotor housings can warp. Also not very emissions efficient.

All in all - really cool racing/performance engines, not so great daily driver engines.

 

Tuning rotary engines can be a bit of a black art - they don't use cams, valves, heads, that kind of thing. Mechanically building engine performance involves porting and grinding. Much like 2 stroke engines, the openings in the rotor housings work with the rotor shape and movement patterns to determine when the port (intake or exhaust) opens, how long it is open and when it closes. It can take a lot of trial-and-error to find just how much metal to grind away and what shape to use to get the best effect with intake and exhaust timing and flow.
