I am not aware of any "comprehensive" books or videos available individually, however the instructional pages within the program (as well as included paperwork) you get when you purchase the TSR Port 2000 program will answer any questions you should have. We also offer 10% discount to first time kit buyers. We repair all handpieces and motors and also offer carbide resharpening to our customers. We sell very few of these due to the costs and the size. The largest is the #3mc which is has a head length of 2inches and head diameter of 7/8". We sell this handpiece ten to one compared to the others. Our most popular is the #1mc which also uses left hand carbide which are for backwards rotation (left hand rotation). Our smallest is the #182mc that must be used with the long adapter that will attatch to the #93 inner shaft. Our price is $310.00 for the TXMC.We have three different right angle handpieces. Our's comes standard with the metal SXR1 foot control where as Foredom comes standard with the plastic foot control.

The TXMC is the same motor as Foredoms TX series and both will use the same shaft(#93) and sheath (#77). :cool: Our TXMC motor is from Foredom, so they are interchangable. i dont think the foredom and cc are interchangeable and like i said the foredom stopped making the micro right angle wand which is pretty much the whole reason to buy one. Yeah cc are the best but they are so much more than everything else ,thing better not burn up in 6 months either. If I could, that's all I would do is cut ports & play with 2-strokes. Be very wary of using the port duration charts in A.Graham Bell's book, they can get you into trouble fast.

If you're willing to accept that it takes trial & error to learn porting it is very rewarding to tweak your own engine and make it rip. Also, keep in mind that when you raise the exhaust port you loose compression and you will need to do something with the head to regain compression.
#PORTING KIT USNG MODS HOW TO#
Do your homework and know how to use a degree wheel, know what port timing is and what blow down is. You should also know what type of pipes you are planning to use first. No port height adjustments should be made without using a degree wheel to measure port timing first. A good rule of thumb is no wider than 70% of bore diameter. This will either wear out rings prematurely or break them. Too wide will cause the rings and or the pistons to go too far into the exhaust port. Too high will get you a high RPM narrow power band with no bottom end. When cutting the exhaust port you have to be careful not to go too high or too wide. Match porting the cases to the cylinders transfers and then narrowing the divider between the transfers updrafts will make a difference. Look at how much volume in the transfer updrafts was lost when they sandwhiched those two cylinders together. The biggest deficiency in the Banshee ports is the transfers. Reshaping around them to help the flow into them will help throttle response though. The only thing you will accomplish is slowing down your throttle response.

DO NOT open up the intake ports! I have had several buddies who have done this alone as the only port mod & and after full port jobs with a dyno test before & after and it makes no horsepower diff. It's a must for opening up & changing transfer ports.
That's where I got my right angle handpiece. There used to a section at their web site(where you could buy used or demo tools. I don't know if they still carry the stuff, but Rio Grande jewlers supply is where I got most of my porting tools. Now if I have got something wrong in anything here I am sure someone will jump right in and correct it. Also another thing to think about is you need to port to your pipe. So you can screw up a cylinder real fast. You will alway make more power moving the exhaust port up. You will make more and better power opening up, and getting the angle of the incoming gasses right, on the transfers. You will make power opening up the intake. Take it slow you will be learning a lot in a short time
John Robinson book Motorcycle Tuning Two-Stroke ISBN 075061806X (That is where the high torque motor come in) The grinding makes lots of heat and you can acually liqufy the metal and it make a hard spot that become harder to take off.Ī Graham Bell book Two-Stroke Performance Tuning ISBN 1859606199 A little penatrant or WD4o will keep the clogging down.Īlso when you are cutting aluminum dont bear down hard and use high speed. Double cut seam to take it out faster, clogs up more, single cut leaves the surface rougher(could be the shape I am using). Also a few 6inch long to get into the transfers. You prolly won't use it at that rpm much but when sanding it nice. You need a high torque motor that turns up to 20,000 rpm's. There is useally some good prices on there, and some decent knockoffs that will do a good job.
