Thank's for the comment Itll take a few videos to cover it all but it should shed a bit of light on the topic and shows that it is not just a matter of taking to them with a die grinder and there is some means to deciding exactly what changes to make when modifying them with a bit of certainty rather then just trial and error methods.
Have you looked at the influence of increased blow down versus power with no change in exhaust timing or pipe? As the engine is bored out, the inclined boost and transfer ports are lowered WRT the exhaust. I am wondering if we should raise the cylinder> increase exhaust duration or leave it as it was prior to boring and what the effect will be.
I would love to hear more on the specific time areas and blowdownl areas. Now I know how to go about the calculations but the thing is I just dont know what STA-s to shoot for for a specific application. I know Frits Overmars suggests to shoot for aprillia rsa 125 STA targets but arent those targets ment for very high reving engines with the max powerband way up high in the rpm range. What would the STA-s be for a more mild tune ?
Two Stroke engines are not something that interest me so much anymore. But how you do this work is Very interesting. Looking forward to watching these video,s. Thanks for sharing your knowledge. Peter.
I have a 100 CC 2 stroke engine and I rebuilt that engine and it is performing fine but it is drinking a lot of fuel, probably I am getting fuel economy of 10 km per L and my engine makes only 8 HP, so what is the problem
Id say your carby is way too rich for some reason, maybe check the float level for starters, it is hard to say without seeing it. Excess fuel consumption can be several causes.
I need to watch and memorize every second of all videos AuM does - this is the kind of deep knowledge I always wanted RUclips to be - amazing.
Not so much honest videos out on yt BUT you very much stand out, please keep going.
Thanks for sharing your knowledge, some people just know how to teach and explain things, you're a natural at it .
Thank you for the comment.
Mate your videos are just the best definitely one of the best mechanical RUclipsrs I've watch you explain but down to a T
Thanks for the comment
Following with great interest. Keep up the good work, much appreciated.

Wow fantastic information. Look forward to continuing with these videos. Thank you very much !!

This is some serious high end porting
LOL

Cheers Peter
Next 2 videos will be up by the weekend
Love you vids mate can’t wait for the next
Next one will be tomorrow.
See it it’s old news now lol now for the next one thanks mate
Man, Sean Bean really knows his way around a two stroke.
Great channel: learning a lot. Liking your Yoshimura shirt.
Thank you for the comment
Nice video man I am building a minarelli v1 motor and planing to modify the cilinder
Hopefully this series will help.
Great explanation 👍
Cheers

@@AuMechanic thank you sir for helping me , it really helped me
Hello is this applicable for longrides
Longrides ?
Its applicable to all 2 strokes if that answers the question.
@@AuMechanic thank u
Where can i get the software to run the analysis?
See the description section under the video.
What software do you use?
There is a link in the description section below the video I just updated.
Is this what people also call blueprinting
No this is about port mapping.
