I believe it was fuel with ethanol. Put it back together after the last seize and used a mix of 110 and 91 to get 94 octane. Using red line oil at 40:1. Runs good now. Haven't pulled the head to see what the piston tops look like yet but will soon. Still need to do some carb adjusting but it...

Have both cooling ports running. Seizure on intake side always means lubrication failure. The fuel I was running turned out to have ethanol= death of 2 stoke. Have confirmed ethanol free fuel now and red line oil. Will be testing again next week. Sent from my SM-G930V using Tapatalk

yeah positive. Never could hit WOT. Never held open longer than 4 seconds. Issue is fuel delivery and lubrication. Sent from my SM-G930V using Tapatalk

not even close, but thanks. Sent from my SM-G930V using Tapatalk

Just did the math on mixing fuels. 1 gallon of 110 to 4 gallons 91= 94.8 octane. That should be good! Brian at Riva told me that in order to run 91 octane pump gas I need 37cc domes with 83mm pistons. Currently I have 82mm pistons with 35cc domes. So with 37cc domes and 94 octane mixed with red...

I'm dropping compression. Was running 35cc domes 180psi. Dropping to 37cc 170psi. I know altitude and temp play a huge factor, I just don't know how much. Sent from my SM-G930V using Tapatalk

I miss spoke about my fuel mixture. I mix 4 ounces oil to 1 gallon of fuel. I was using yamalube, switched to red line. I plumbed another cooling line and replaced all fuel lines. 170 main jet, 130 pilot, 2.3 n/s 95 gram spring, 20 psi pop off (verified 5 times). Switching to 37cc domes with an...

Cool, Thank you for the offer. I may take you up on it. Currently I'm waiting on another set of pistons. They should be here by the end of next week. Thanks again Sent from my SM-G930V using Tapatalk

Thanks Mike, at this point I don't have any other option than to try stock compression or race fuel. Just seized another piston! [emoji34]. Just got off the phone with Riva and they say I'm good at 93 octane. My region only has 91. Most likely that's the the issue. Since intake side seizures is...

Here's a couple pics. Sent from my SM-G930V using Tapatalk

I don't think so. There would be white foam if it were. Ill check the next time out. They are the stock reeds. Everything inside the carb is good, it's new. Pop off is set at 20psi. Check 5 times the same each time. Engine is uber sealed! Held 10psi for over 3 hours. I had to release the...

I haven't checked that, but will the next time out. Everything inside the carb is good. Pop off reads 20psi. Checked 5 times. Same each time. Engine is uber sealed! Held 10 psi for over 3 hours. I had to release the pressure to continue. Thanks ill definitely keep that in mind. Btw the front...

Yes double and triple checked. Sent from my SM-G930V using Tapatalk

Compression is 170 in each cylinder. Riva told me that I should be good for pump gas. Sent from my SM-G930V using Tapatalk
