Sent from my SM-N920V using Tapatalk EL O freaking El 18 bucks to build a tester at home and DIY if it truly isnt leaking, Id start at a 162 main, CEL needle in the middle, 48 pilot with 1 turn out on air screws. Id do a plug chop first to see how the main jet looks. that should be enough jets for that setup. Edited June 8, 2018 by Ayesully810 Quote Link to comment Share on other sites More sharing options...
christoph.tamz Posted June 9, 2018 Author Report Share Posted June 9, 2018 I'm at a 164 maybe moving to a 162. Plug chopped confirmed Sent from my SM-N920V using Tapatalk Quote Link to comment Share on other sites More sharing options...

Ayesully810 Posted June 9, 2018 Report Share Posted June 9, 2018 and how does it start and idle ? id get your pilot and air screw dialed in. A CEL needle on the 2nd, middle or 4th is where you might end up. You sure your arent rich? post pics of the plugs Quote Link to comment Share on other sites More sharing options...
strongweld Posted June 11, 2018 Report Share Posted June 11, 2018 My bike also stumbles a little on the Dyno between 4 to 6000rpm, builder says it is a common problem when running race gas with only 185 psi compression, he likes 220 psi for strait 110 Quote Link to comment Share on other sites More sharing options...

Not to mention harder then hell on bearings. I wouldnt even run my alky bikes at 220psi cause there isnt enough, if any, gains to out weigh the strain on the engine.

sheerider11 Posted June 30, 2018 Report Share Posted June 30, 2018 I would think that much would kill your top end. Can't see it revving out that well. Sent from my SAMSUNG-SM-G891A using Tapatalk Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted July 3, 2018 Report Share Posted July 3, 2018 The only time I've ever liked that much compression is when I ran 1/8th mile oval. But any time you're running all the way through the gears and revving it out,by hate just to much compression for a banshee motor. Some 250R stuff does ok with that, not these twins though.
