hoppedupandcutdown Posted August 30, 2020 Report Share Posted August 30, 2020 You have WAY to much compression and are certainly running to low octane fuel. 1 Quote Link to comment Share on other sites More sharing options...
Eric_C1 Posted August 30, 2020 Report Share Posted August 30, 2020 Increase the compression, go for the world record highest compression banshee Quote Link to comment Share on other sites More sharing options...
n2otoofast4u Posted August 30, 2020 Report Share Posted August 30, 2020 WOW....... that’s quite the setup. It is detonating from the high comp, poor fuel, and overall unhealthy combination. I’m amazed it’s still running and not a pile of parts. Have you been breaking kicker gears? Quote Link to comment Share on other sites More sharing options...
SKEETER Posted August 30, 2020 Report Share Posted August 30, 2020 A trinity plug lock is what you need. Fixes that problem! Quote Link to comment Share on other sites More sharing options...
Justsayin6916 Posted August 30, 2020 Author Report Share Posted August 30, 2020 I run racing fuel and redline 2stroke oil is there any way to bring that down any withe like bigger dome or smaller domes I live in Las Vegas,nv and it seems like a plug lock would be stupid to do because it shouldn’t need a plug lock ever something is not right I just need to figure out what !

Justsayin6916 Posted August 30, 2020 Author Report Share Posted August 30, 2020 Should I try and run a higher octane Quote Link to comment Share on other sites More sharing options...
Justsayin6916 Posted August 30, 2020 Author Report Share Posted August 30, 2020 No it kick over with a little itty bitty kick doesn’t even need to be a full one bike fires every time cold or hot doesn’t matter Quote Link to comment Share on other sites More sharing options...
Tedder Posted August 30, 2020 Report Share Posted August 30, 2020 You need to get that detonation under control or you will destroy that motor. I don't know what type of riding your doing but imo - 210# is to much compression and what I'd address first but there are other possible things that could add to your problem. To low an octane fuel, to much timing, lean jetting etc 1 Quote Link to comment Share on other sites More sharing options...
Justsayin6916 Posted September 1, 2020 Author Report Share Posted September 1, 2020 Ok I don’t even know if it has an adjustable timing plate should it if it the stock one and what should my timing be at with an adjustable timing plate and if it’s to lean to I go up or down in my jetting to richin it and would it do that if it was to rich Quote Link to comment Share on other sites More sharing options...

kawa110 Posted September 1, 2020 Report Share Posted September 1, 2020 You need to verify the compression. If it is that high u need different domes. +10 is too much unless you got a lot of clues,correct fuel, correct squish, correct jetting/tune. What brand compression testerWhat’s ur elevation Remove stator cover and look at the plate the stator is bolted to. You’ll see if it is adjustable. The stock plate is cast metal. A aftermarket plate is generally billet aluminum and Wher the case halves meet will have a mark with numbers for adjustment.

Justsayin6916 Posted September 2, 2020 Author Report Share Posted September 2, 2020 I have two different compression tester and I done the test each side like 8 times each with each one and cane up with the same from both and both are different brands and I think my elevation is 2000 ft above sea level I live in Las Vegas I have 19 cc domes what size would I need do I go up or down in sizes Quote Link to comment Share on other sites More sharing options...
