    Well as far as gas is concerned, it depends on where you live. I have 93 octane available where I'm from. As for domes and compression, you should read up some. When I had my 4mil I was running 24cc domes for pump gas. I had a cranking compression of about 155 with a dune port. Sent from my VS980 4G using Tapatalk

    You might want to check your domes and what your compression is. If you do have 4mil domes and they are like 19 or 21 cc domes, 91 octane is way too low of octane Sent from my VS980 4G using Tapatalk

    What fuel are you running? I would find out what jets are in your carbs so we can get a good idea of what's going on Sent from my VS980 4G using Tapatalk

    Hey sleeper. Is there a reason you say no to 50:1? I know some oils can be run at that ratio Sent from my VS980 4G using Tapatalk

    Does it have a spacer plate or are the domes cut for a 4mil Sent from my VS980 4G using Tapatalk

    What size bore do you need them for Sent from my VS980 4G using Tapatalk

    After researching cheetah motors and talking to some people who have build them, it seems the magic number is .050 to .055 Sent from my VS980 4G using Tapatalk

    Ok. So a quick update. I finally got around to screwing with the motor. I tore the top end off and flipped everything. I flipped over the base gasket, swapped the pistons from side to side, and swapped the domes side to side. Re torqued everything down and redid my squish test. I now have .039 on both sides. I don't know if it was something stupid like I didn't have the base gasket squished down enough or if just a slight difference in everything side to side made it off. But anyways, everything looks good now. Now I just need my domes recut to get my squish where I want it. Thanks to everyone who offered their insight Sent from my VS980 4G using Tapatalk

    It's the trinity cut domes that are a problem. There seems to be a lot of their domes that are cut wrong. Instead of the squish band opening up as it comes to the middle, it gets tighter. Sent from my VS980 4G using Tapatalk

    Hopefully someone can give me some insight. I will look into the deck height and stroke this week Sent from my VS980 4G using Tapatalk

    Yes, it is a mono-block. I'm sure I could get new domes made but I want to know if maybe there is something I should be looking. To me having domes cut to the different sides is a band aid fix to something else Sent from my VS980 4G using Tapatalk

    I got what you are saying about the crank. Thanks for that insight.As far as measuring the pistons at tdc, I don't have a dial indicator. I'll have to try to figure out something for that Sent from my VS980 4G using Tapatalk

    As far as I know the pistons are matched. Sent from my VS980 4G using Tapatalk

    Yes, it's Andy's crank that he builds Sent from my VS980 4G using Tapatalk

    Just a quick update. I had another head and set of domes. I'm getting the same results Sent from my VS980 4G using Tapatalk

    Hey guys. I'm having an issue with my motor. I just put my motor back together after getting a new crank ( 4mm to 7mm) I went to check my squish and I'm getting different readings between the cylinders. On my clutch side I'm getting .042, on my stator side I'm getting .048. I took the head off and swapped domes. I'm getting just about the same measurements on the same sides ( measurements stayed with cylinder, did not follow domes). So what could be the problem? The motor is a 499 7mm cheetah Crank from Andy at No Limit 0.032 base gasket Domes from Andy at No Limit Sent from my VS980 4G using Tapatalk

    There seems to be a few people who have trinity domes where the squish band gets tighter as it comes to the middle of the dome. The squish band should get looser as it gets to the middle

    Are you sure your powervalves are working? If they are, have you checked to see if they open all the way up? I had to cut my powervalves to match the exhaust port.

    I had the Janssen (fireball) arms on my old quad and now have fireball on my current quad. Great arms for sure

    Measure your squish then you will know how much you can mill your head. For a mild motor a good squish would be about .045 to .055 inches
  22. hercalmighty
    It's the measured distance between your piston at tdc and the head. It's pretty simple to do. Search for the procedure and do it before you take your head off.

    Do you know what your squish is? If not, measure it before you get the head plained
  24. hercalmighty
    I read another post of yours that said the plate has o rings in it, correct? Now my question is, are you checking tour squish with the plate and gaskets or just the plate with orings
  25. hercalmighty
    That is a very loose squish. What is your current setup. What is a shim kit? Are you talking about a spacer plate?
