bansheecaptain Posted August 12, 2009 Report Share Posted August 12, 2009 I just put a noss head on my bike with 20cc domes and it seems to have a bit more knocking sound and I check the squash and it seemed fine unless I did the check wrong. Just asking if its normal or is there something wrong Quote Link to comment Share on other sites More sharing options...
blowit Posted August 12, 2009 Report Share Posted August 12, 2009 I just put a noss head on my bike with 20cc domes and it seems to have a bit more knocking sound and I check the squash and it seemed fine unless I did the check wrong. Just asking if its normal or is there something wrong Higher CR motors will tend to have a bit more pop to them. Now an actual knock is a problem but if you are jetted right with 0 to +4 timing on pump fuel, you should be fine. B Quote Link to comment Share on other sites More sharing options...
bansheecaptain Posted August 12, 2009 Author Report Share Posted August 12, 2009 Ya my jetting was a tad rich before I put it on and I asked on here if I need to change jetting and they said no so I would assume my jetting is still good. And ya I'm running +3 timing Quote Link to comment Share on other sites More sharing options...

bansheecaptain Posted August 12, 2009 Author Report Share Posted August 12, 2009 Yep. What would be a good way to double check that. To check the plugs or pull the head apart or is there a short cut Quote Link to comment Share on other sites More sharing options...
