jscharphorn Posted June 13, 2015 Author Report Share Posted June 13, 2015 I know now that I need bigger carbs, Shawn was thinking maybe it looked like the 170 was lean because it was so rich it was washing the plugs 1 Quote Link to comment Share on other sites More sharing options...

jscharphorn Posted June 13, 2015 Author Report Share Posted June 13, 2015 I am ordering 39mm carbs so will not be doing any more testing until I get the lockout on and the bigger carbs, thank you for trying to help. 1 Quote Link to comment Share on other sites More sharing options...
dozer Posted June 14, 2015 Report Share Posted June 14, 2015 After you do all that add some Damn timing. It'll help a bunch. Just remember more timing needs more fuel. 1 Quote Link to comment Share on other sites More sharing options...
jscharphorn Posted June 14, 2015 Author Report Share Posted June 14, 2015 Thanks for the tip on more fuel with more timing, I did not know that. 1 Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted June 14, 2015 Report Share Posted June 14, 2015 You still need to check squish , I like them .050 -.055 that's why I was saying maybe that particular motor was set up for a .012 base and would bring squish up to a safe area 1 Quote Link to comment Share on other sites More sharing options...
jscharphorn Posted June 14, 2015 Author Report Share Posted June 14, 2015 I have not had time to check yet, wouldn't going with a smaller base gasket make the squish even tighter ? Fast recommended a .45-.50 2 Quote Link to comment Share on other sites More sharing options...
Surfrjag Posted June 14, 2015 Report Share Posted June 14, 2015 Right but if its .060" squish now then that might be your problem. Like if its set up for a .012 base and has a .020 instead. It wont have the torq to get out of the hole like your describing. You dont know till you check... Quote Link to comment Share on other sites More sharing options...

jscharphorn Posted June 16, 2015 Author Report Share Posted June 16, 2015 I only had soldier that was .50 thick and looks like squish is about .48, I need to run to town and get something thicker to make sure. Quote Link to comment Share on other sites More sharing options...
jscharphorn Posted June 16, 2015 Author Report Share Posted June 16, 2015 I ordered 39pwk carbs and am going to start with 175 mains and 52 pilots, I will not have the chance to test until Monday. If it does not work then I will bump the timing. Quote Link to comment Share on other sites More sharing options...
RadarRacing Posted June 16, 2015 Report Share Posted June 16, 2015 If it doesnt work then its not the timing being a couple degrees low. Loose squish usually doesnt improve anything by adding timing. Quote Link to comment Share on other sites More sharing options...
jscharphorn Posted June 16, 2015 Author Report Share Posted June 16, 2015 I checked the squish with thicker material and being my first time doing it I will need to have a second opinion on it, I did hold it even with the piston pin and had it in about 1.5" across the top of the piston and is what I read is from .45-.50 seems closer to the center of the piston is were it has a bigger gap.

troyzstang Posted June 16, 2015 Report Share Posted June 16, 2015 Just curious did you use two pieces( left & right of piston)? I just went thru the same issue. Simply dropped from .020 to a .012 base gasket. Squish dropped accordingly and bike runs as it should now. Fucking amazing Like a new bike. Good luck. I hope you figure it out .
