pecanfmr Posted June 12, 2009 Report Share Posted June 12, 2009 (edited) If youre going to do it, do right! If you get it ported to your style of riding by someone who knows their stuff you will never regret it. I could not possibly be happier with the results from my HJR port job. There are several builders out there that seem to do a great job, just personal preference, turn around time, price, etc, that goes into making your decision. If you can find someone close to you that has a good rep then you wont have to worry about shipping since price is an issue. One thing though, getting the head shaved and bumping the timing up will really complement the port job. -RM Edited June 12, 2009 by pecanfmr Quote Link to comment Share on other sites More sharing options...

Keyser Soze Posted June 13, 2009 Report Share Posted June 13, 2009 You will notice a difference .30 and +4 timing. Make sure you check your squish and compression. You may have to run a mix. Quote Link to comment Share on other sites More sharing options...
