junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 So I put 20 domes in it and got 65 squish and 110 compression Quote
junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 So what the hell go buy 18-19 you think I'm about to put theses 17 in it that came with the motor Quote
junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 I'm stumped changing dome size is not changing compression on new motor what's the deal Quote
junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 All new parts I think the base gasket is to thick I should have ran the 20thou like I all ways do but this was a kit so I just used what came with it I in the process of doing the heat cycles In the shop then ill do another compression check after the rings are a little more seated? Quote
junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 But don't understand why dome lowering is not changing compression psi maby the rings are not seated yet? You think? Quote

junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 Everything is new i got a buddy comming with a snap-on compression gauge we will se what it say against my gauge I hope my gauge is shot Quote
junkyarddog Posted March 26, 2014 Author Report Posted March 26, 2014 Yip gauge is shot I put a brand new snap-on gauge in side by side with mine and ya shot mine said 80lbs and snap on said 125 and that's with 22 domes so I'm thinking 20's will be on target and swap the base gaskets out with 20 thou's and hope that will drop my squish Quote
junkyarddog Posted March 26, 2014 Author Report Posted March 26, 2014 Ya I'm so glad it was the gauge it had me stumped So I put 20cc's to it and it put out 140psi I'm going tomorrow to a local shop in the morning to buy domes either 19cc or 20cc haven't decided I think 140 is pretty good but would 145-150 be better I know 175psi is the threshold for pump gas And pump gas here is only 91oct Quote
junkyarddog Posted March 26, 2014 Author Report Posted March 26, 2014 Ya I'm going to get 20's Tomorrow So is the 65ish squish gona effect anything iv never had that much squish most bikes we have build have 40-50 so 65-70 what's that going to effect sort term and long term Quote
junkyarddog Posted March 27, 2014 Author Report Posted March 27, 2014 Hey (ride.race.live) just wanted to say thanks bro It's only me here and some times I need some good ideal's to kick around thanks man Quote
junkyarddog Posted March 27, 2014 Author Report Posted March 27, 2014 I put 19cc domes in it they were out of 20's And got a .020 base gasket Got my squish to 55 Compression is 147 Runs great I haven't rode it threw the breaking riding I do just heat cycles so far but sounds healthy for a trinity cylinder lol Quote
junkyarddog Posted March 27, 2014 Author Report Posted March 27, 2014 Ya and I tested that junk gauge against two buddy's that had the same one and there all junk we all bought them from oreilys auto parts house Quote
