Why are you laughing at her.
We have degrees C and degrees F and they are both the same freehundredansixty degrees of heat - yea.
Your the dumb bastards, quit taking the piss.

Expert sketch

Most days I feel like 'Anderson' when I deal with some of the customers I have.

Some of them are paid 6 figure sums and still act just like the video, its never their problem

Draw 7 circles in red ink and warm them with 360 degrees of heat

After 3 years of slow development, the NSR300 finally is getting what it wants. Proper pipes. Many thanks Wobbly for the engmod help and pipe design. Also thanks Sketchy for the CAD help. Now its time to roll and weld. If I do a good job I will post the finished pipe pics. No pressure.

Intrigued with some of the non symmetrical profiles - take your time

will be interesting to see the end result

Firstly, my apologies for taking the best thread on the internet off-topic, I promise this will be my last "expert" post.

Anyhow, now that I've picked a thermodynamicist, I thought I could also use someone to conduct a post-race analysis of the logged data. You know what I mean; someone that has a firm grasp of vehicle dynamics and able to take one look at the data dump and know immediately what to do:

... ....... ........ .... that is so totally true, and the idiots will be getting well paid, better than the expert anyway.

And that guy that is mocking his wife, well I guess he will find out who the real dummy is...

i finally got the new plating back on this cylinder . that acid sure reveals any casting or weld porosities. anyways the platers around here put large chamfers on the windows so i instructed them not to touch the windows and i would put a small chamfer on them myself. the outer portion of the cylinder top that seals the water in, needed .5mm shaved off to make it flat again and in doing so i welded the outer portion of the head to compensate.

also the stroke is 2mm longer than standard so the piston sticks above the top deck. looking back i probly should of welded the cylinder top so i wouldn't have to fuss with the surfaces of the head but oh well. my question is i have to recut the squishband and chamber because the piston is about 1.5mm higher now which puts the spark plug 1.5mm closer to the piston. i was going to weld/machine the area where the sparkplug seats to the head so i get my plug/piston clearance back, basically raise the plug in simple terms. is there a common rule for the distance the plug strap should be from the piston top or should i just put the distance to what it was originally ?

all that remains now is shape the transfer passages with devcon and chamfer the windows and get this head sorted out and it should be able to run

Peewee, ground strap to piston =5mm.

Are those exhaust segments laser cut? You must know a guy. I would cut those out with an electric shear.

Does anyone have a comparison between the standard and A-kit Honda RS125 exhaust duct exit?
Wondering if the actual exit is the same meaning an A-kit spigot could be used on the standard cylinder. I know the exhaust spigot on the A-kit is tapered whilst the standard one is round (stepped with the duct).

When are you sending that box of stuff up?

I will start tomorrow, if you promise not to do any more videos with your knees showing

Health and safety, no knees casting then it is. Just let me have a go at that box of stuff.

I have recently purchased a used HE-JA barrel and head , just searching for info on what piston they used with it . It's a flat top piston with the ring peg in the centre .
