e10 and 10.5 to 1 in a 200x

standard PUMP gas 91 octaine is fine. it is only a very TINY percentae of eth. the 10:1 will be fine on the 91 but your going to need to properly tune it. one thing you may consider to ensure it's tune correctly is getting a dial-a-jet kit from online and use that. you can use the stocker jet size and proeprly dial in the fueling needed w/o issues and it woudl probebly be one of your best bets.


BTW guys any pump gas now has a percentage of eth. ANYwhere in the states, so worrying about it is not going to fix the issue. We jsut have to make sure our upkeep on out trikes are done correctly and more often to get it to work right.

I run my 200x with a 12:1 piston in it on e85. Ive had vey few problms with moisture ever, and its been 2 years. Seasonal changes if i havnt rode it much have caused problems like twice. all the crap about it eating seals and gumming up carbs isnt true from my experience.(it will eat some seals, but on a 200x ive had no problems) i havnt had to crack my carb open at all in those 2 years since i switched. the rejet from gas was the bigest issue ive ever had with it. Starting in the winter is also an issue, but there are ways around that.
