banshee9090 Posted October 29, 2010 Report Posted October 29, 2010 I got my 4mil porting done,during worm up the motor I noticed the temperature and comparison of the left cyilnder is higher than the temperature and comparison of the right cylinder, I have shift to stocck cool head put still the left cyil. Temp. comp. is higher than the right cyil. what could be wrong , one or more port in the right cyil. is biger than other in the left ? any suggest pleas Pleas note With Stock cool head compr. Is 150 psi for left cyil and 140psi for right cyil. with Pro design 22+2mm dooms, have 188psi right cyil. 180psi for leift . Quote
AKheathen Posted October 29, 2010 Report Posted October 29, 2010 did you map out your ports with everything bolted down good and make sure they are all symetrical? are they all chamfered good, so the ring doesn't snag? are you getting good spark and fuel to both cylinders? you said the compression was even to both cylinders before break-in, right?

AKheathen Posted November 2, 2010 Report Posted November 2, 2010 also, make sure you didn't put one ring in up-side down. some rings have a bevel on the inside, or other recess, like square. some are tapered. that is to let more pressure in behind the ring to help seal better, which needs to face upward, and tapered rings have the leading edge down. if you got one in up-side down, it would not have cut good, and will have low compression.

sleeper06 Posted November 3, 2010 Report Posted November 3, 2010 The intake will not effect compression,but exhaust/transfer heights/widths will.I have also had temps vary due to diffrent amounts of brak in lube in each cylinder,after first ride and cleared it out temps match Quote
