i have a ds650 with ported intake and race head ct pipe with a mikuni tm45 been running methanol on it with no jets worked ok but wanting to put it back on pump gas any ideas on what jets i need to start with. and where i can get them thanksTextText

 

Ron woods has you jets rotax.net get a few mains and pilots so you can dial it in.

need #96 needle , y6 jet tube , if the acc. pump is activated you need #50 nozzle set at short stroke/duration. now as for main I'm running 155 now and a 37.5 pilot. you being in warmer temp. might need something a little differnt.
good luck & post some pics so we can see that beast!
any other questions just ask!
