dusty_v141 Posted November 4, 2009 Report Share Posted November 4, 2009 Hey im porting my cylinders and was thinking about puting in some boost ports . I will be rideing trails and i own a motocross track so do yaw think it would make my power band too short. and what size would be good too go with; i have heard that if you make them too big not enough of the fuel mixture will go into the crankcase and will not get enough lubrication too the rod and crank bearings. is this true? thanks for all the replyes.

Screaming Yellow Zonker Posted November 5, 2009 Report Share Posted November 5, 2009 ok first question... what are your reasons for trying to port your cylinders?? Next in your sig it says -2 degrees timing... why not run advanced timing where it gives you power? If you are looking for more power advance your timing to 4* advanced and save your money for a cool head... Quote Link to comment Share on other sites More sharing options...
dusty_v141 Posted November 10, 2009 Author Report Share Posted November 10, 2009 well when you advance your timing it gives you more power down low and takes away from your topend so if you retard it you get more topend. i was running asphalt and was trying some stuff and it does work. i also put at +4 and ran up the road too holding a gps and checked my top speed then did it at -2 and it was faster but not alot it just lets it rev farther.

lmaloch Posted November 12, 2009 Report Share Posted November 12, 2009 Wow. Let us know how it turns out..... Quote Link to comment Share on other sites More sharing options...
potpye Posted November 14, 2009 Report Share Posted November 14, 2009 You should have someone that knows what they are doing, you cant just hog the jugs out. Also you have to be careful when drilling the boost ports as you can go through the side of the cylinder real easy. Quote Link to comment Share on other sites More sharing options...
