Thanks Robert, excellent article

Yea thanks Bobby.

yup...

Tq bro nice porting

Such a pity little of it relates to pb's

Great article to demonstrate just one principle of porting. The article shows a motor not even remotely similar to a Cag but it shows you guys the importance of the angles on the transfers and how altering the transfers has to be done properly. Very well illustrated.

if you search on that website you can find out how to make a hoimemade muffler

great article to learn, bartw your pretty much right on, while very informative do not replicate, that is for boat motors that are hitting very high rpms, and have pretty much no load. That article helped me learn to port rc's (goped motors) and its a very helpful article, glad you posted it up for pbn to see.

How do you make boost-ports on a 50cc pocket bike engine

you need to get a machinist to do it for you.. unless you got a very steady hand and a dremel. a boost port is nothing more than another transfer port on the opposite end of the exhaust port..

It looks like the link has expired which is, may I say, annoying because I had to waste 1 minute of my life to find this out. I would have thought this link would have been exempt from the delay seeing as it was Robert that put it here. Time to de-sticky this one.

Here is the link.
