mx1986 Posted July 30, 2015 Report Posted July 30, 2015 Recently got a 10 mill cub that had some custom domes in it. They read 21 10 .018 on the stator side and 21 10 .022 on clutch side. I know what the numbers stand for I am just curious to why they are different then each other. Quote
Surfrjag Posted July 30, 2015 Report Posted July 30, 2015 Check squish. Someone may have mixed and matched? Quote
RadarRacing Posted July 31, 2015 Report Posted July 31, 2015 CC , angle, and "step" or lip at the outer edge of the squishband in thousandths. They may have damaged a dome at one time and used another good dome in a pinch. 2 thousandths isnt a huge deal really if squish isnt on the tight side. Check squish for sure and you may find that the squish is off by 2 thous or they may be the same. I have seen numerous sets of brand new domes out of the box that the step was 1 or 2 thousandths different. Quote
Bennett131 Posted July 31, 2015 Report Posted July 31, 2015 Wouldn't it be .004 thou difference? Still don't think it's a huge deal though. Quote
RadarRacing Posted July 31, 2015 Report Posted July 31, 2015 Yeah. 4 different My bad. Probably had an alky set with tighter squish and a gas set with looser squish and mixed and matched a spare after messin one up. I run the same compression but tighter squish and a bit different dome on alky. Quote
