Stalling

[Jboss112]

I have a 2000 Yamaha 350 twin banshee it ran fine when I got it I got it about 3 weeks ago I event up and got 89 octain and mixed oil at 50 to 1 it ran fine but fouled a plug replaced plugs and drains fuel when to 93 and 32-1 on the oil and it started backfiring and stalling took off carbs and cleaned them all up put all back together took tank off cleans the filters inside and put that back together now it sputers a little but still stalls when riding and backfires ever now and again but it will idle its sometimes hard to start and sometimes starts on first kick and seemed to have low compression when it stalls it will sometimes start right back up and other I have to push it home     please help if anyone can

Yes it is only way I knew to explain the problem

Pressure test, compression test, if those check out move on to electrical testing. It could be something as simple as you put the carbs back together wrong and mixed up parts between the two or are missing something

Also pull your petcock out and make sure it's clean and fuel flows good from it. I have seen guys spend a lot of time chasing down an issue and the whole time there fuel wasn't getting to the carb fast enough

I took one carb apart at a time and put it back together before I took the other one apart.   So can't be mixed up.  Took picks of everything before I took it apart, just so I knew it was going back together properly but I will run the tests then get back
