With all the pseudo hop-up analysis,"Mater of fact" statements going on in another thread,I felt the following link should be re-posted.Some of the lurkers among us, may be unsure with some of those claims presented as fact.These folks might like some alternate general high performance/tuning information to apply to there own engines.
Here is one book,while somewhat dated,is a pretty good "two stroke" treatise.The late author was mostly held in high regard as a tuner/author.
Take a look at the other pdf's on that page too.
You'll prolly need a basic Pdf reader to see it.This is the whole book...free of charge

Google books also has a nice "free" on-line selection of reading material on this subject,to gain futher prospective.Some are just snippits,some are whole sections.
An example would be:

Thanks Nitro, I have a PDF copy of this but it's missing a few pages. When I get some time I'll see if this copy is more complete. You seem to be pretty techy. Having read Mr. Jennings overview of the design and function of "tuned pipes" or, more properly, "expansion chambers", do you think these after market suppliers are really selling a well designed expansion chamber for model engines?
