01bansheefox Posted April 5, 2005 Report Share Posted April 5, 2005 (edited) This the right thread? Not 100% sure on what all the differnt port jobs are Woods? All Around? MX? Acceleration? Dune? Top End? Edited April 5, 2005 by 01bansheefox Quote Link to comment Share on other sites More sharing options...
Ducman Posted April 5, 2005 Report Share Posted April 5, 2005 I would sort of sum up the different port types as what RPM the motor gets "On the pipe" and what RPM does it drop off the pipe. Dune or drag ports are going to make power at higher rpms an give the best acceleration but you have the RPM's higher to get on the pipe. Also the highest HP output. Typically from 6 to 10K. Also usually raise the exhaust port which lowers static compression a lot, so you need a lot of timing advance and pretty small domes to get compression back up for more low end torque to compensate for less low end HP, not necessary, but helps rideability. Then you need race fuel. This is not always true but somewhat typical. MX has the widest RPM range, best in midrange power, and best top end you can achieve without sacrafising too much botom. probably 4500 to 9K Gives you the most useable and widest power range in each gear. Woods, or trail port is more or less a mild port or clean up port. It cleans up casting flaws and opens up the ports a little. It will have a similar power range as stock but will flow more efficiently and make more power from bottom to top than stock. probably 3500 to 8K Gives the best traction and ability to be a gear too low or lug a bit and not make it as necessary to shift down or feather the clutch to get into the band when just rolling on the throttle.

SControl 1 Posted April 5, 2005 Report Share Posted April 5, 2005 Would any of you atempt to port it on your own? Quote Link to comment Share on other sites More sharing options...
Rare Scottish Tree Badger Posted April 5, 2005 Report Share Posted April 5, 2005 Nicely written summary Ducman. Rare. Quote Link to comment Share on other sites More sharing options...
01bansheefox Posted April 5, 2005 Author Report Share Posted April 5, 2005 THen what would you do if you drag/mx? Quote Link to comment Share on other sites More sharing options...
broke Posted April 6, 2005 Report Share Posted April 6, 2005 Port one cylinder for drag and the other for MX. Just kidding, you really can't have the best of both worlds. I still drag race my MX cylinders, but I don't win them all. Quote Link to comment Share on other sites More sharing options...
