SlowMoe Posted February 6, 2017 Report Share Posted February 6, 2017 Putting together a 4 mill stock cylinder. Going to use a spacer. I know it's not ideal, I know, I know. I am wanting to run my 18cc small bore pump gas domes if possible. Question 1: are these domes set up for zero deck height? Question 2: If so, since the crank gives me 2mm (.080") extra stroke each way, I need a spacer/ gasket combination that will give me a total of .100" between the cylinder and cases, correct? I'm trying to figure out which spacer kit to buy off eBay. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted February 6, 2017 Report Share Posted February 6, 2017 Holy crap, all this work to figure out a spacer because your scared to grind on the roofs a bit? Are you using blaster pistons? Quote Link to comment Share on other sites More sharing options...
bigweav81 Posted February 6, 2017 Report Share Posted February 6, 2017 How much does a spacer plate/ kit cost? If you're not in a hurry I may have a new vitos spacer that came with my 4mil crank. Sent from my SM-S820L using Tapatalk Quote Link to comment Share on other sites More sharing options...

SlowMoe Posted February 6, 2017 Author Report Share Posted February 6, 2017 The right angle bits I have are a little too big to fit in A 65mm bore properly. And I don't really heve $300-$400 to spend on tools. my tools fit good enough to drop the transfer floors, open up the exhaust, intake and transfer runners. its $30 bucks for a spacer and bam I have my transfer duration where it needs to be not to mention I may be able to save money on domes since I already have small bore domes Quote Link to comment Share on other sites More sharing options...
SlowMoe Posted February 6, 2017 Author Report Share Posted February 6, 2017 Not trying to be a total cheap ass, if I NEED to spend money I will but like I said I have a YXZ1000R turbo build going on too. Gotta cut some corners Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted February 6, 2017 Report Share Posted February 6, 2017 What elevation are you at? 18cc domes are small for pump gas. You will have to figure out your compression ratio to see if you can us those 18cc domes on pump gas.

hercalmighty Posted February 6, 2017 Report Share Posted February 6, 2017 Have to do the math to figure out your compression ratio. As far as gasket/spacer sizes, measure the lip on your domes and decide what squish you want to run Sent from my VS990 using Tapatalk Quote Link to comment Share on other sites More sharing options...

registered user Posted February 6, 2017 Report Share Posted February 6, 2017 get couple sets of cheap feeler gauges and stack under cylinder to find what spacer /gaskets u want. we cant hold your hand all the time so better think outside da box on your own alittle lol Quote Link to comment Share on other sites More sharing options...
bigweav81 Posted February 6, 2017 Report Share Posted February 6, 2017 I used the gaskets awhile back. Might wanna order several sizes of gaskets. Mock it up, and measure until you're close to what you want. Maybe a few spacer plates as well. Domes aren't that expensive, and can make a big difference in performance.
