TZ could you reverse the cylinder?

Yes, very easily.



But unfortunately the fat part of the pipe would be in the most restricted part of the bike.



Katie's air cooled GP125 gives an idea of how crowded the Honda RS125 NF4 frame is.



Tim's NSR-GP110. The mono shock and "A" frame swing arm are the biggest obstructions to reversing the cylinder.

Mazda 6

That Mazda oil cooler looks the go. I will have a look at Pick a Part for one.

How hot can the transmission oil typically be in a two stroke high performance engine?

It looked like 90 - 100 deg C on my bike. It would be much better to be 30-40 and used for cooling the crankcase and inlet tract of my RV.

Monocycle. not only is Sandra backing the bike into the corner like a flat tracker, the front wheel is off the deck.

250 kart? cylinder on the gp 125? in nsr 50? frame. Either way I like it.

Honda NSR250, cylinder on a Suzuki GP100 engine, RS125 NF4 rolling chassis.

The plate down the center of the cases is so a six speed gearbox can be fitted to replace the old five speed unit. It has a Kawasaki KE175 rotary valve cover and runs a Yamaha RD400 con rod assembly and Suzuki RGV250 big end brg, it currently tops out at 13,500 rpm.

There are several of these engines.

One is fuel injected. The fuel injection system is still under development:- https://www.kiwibiker.co.nz/forums/s...2T-EFI-Project

There are several of these engines. Ok, I'm currently reading the story about Thomas, thought it was an alter ego at first, great reading

About 100°C or more

Two Stroke GP Restorations, worth having a look at. As well as pictures of their restorations there is a few clips of the "real" sound.

Anyone, variable crankcase volume. Piece of garden hose and different lengths (volumes)

Im going to ask a question and I want a general answer
What does a pipe with a bid mid section have or not have in relation to a pipe with a mid section. Ie spread of power

Ideally the crankcase volume is one big volume without any nooks & crannies.
Your setup could act as a pneumatic damper, unless you use a short length of big diameter hose.

I want a McLaren 720S. And a camper. What is a bid mid section?

Probably this position neither, too close to the petals would disrupt flow sideways at some rews.
Longer hose-decrease in idle revs is what I notice.
Bigger diameter hose and direct to crankcase connection would be indeed right approach.
