After Willow Springs Disappointment with the Rotax EVO I took it off and bought a IAME X30 it is still in the box. I checked for drive sprockets they only show up to 12 tooth. Did I make another mistake buying this engine for road racing? Anyone know of bigger drive sprocket or is 12 and a real small axle sprocket enough for tracks like button willow and Sonoma enough.
Hi Jack, Fastech has the 16t drive gears, I just picked one up a week ago. Tig the egt bung, and if your X30 came with a Tryton carb you have to do the exchange program to get the new tillotson carb and manifold. Contact the dealer you bought the x30 from or IAME West to do the exchange program. The Tryton carb is not legal to run in any of the karting organizations anymore! They want you to send the tryton carb the manifold and they will send you a new Tillotson carb and manifold with a carb kit for your trouble. The X30 is legal to run in NCK as per IKF rules and the Tag Heavy weight is 405lbs. Its not in the 2015 Rulebook yet but it is on the IKF website as an approved engine along with the X125. Hope to see you at the next race Jack as I knew you were not happy with that Rotax at Willowsprings!
Hi Ray, as far as I can see, the Rotax EVO is not on the approved Tag engine list for IKF. The X125 and the IAME X30 are on that list for Sprint and Roadracing, Tag Light and Tag Heavy classes. The X125 and the X30 are in the IKF 2015 rule book for Sprint racing and on the IKF website for Roadracing under section 300 at 375lbs for Tag Light and 405lbs for Tag Heavy. This is found under New Rules on the IKF Website The Rotax EVO has not been Homogilated. As far as I know any older Rotax engines that have any of the EVO updates are not approved either. Lets all play by the rules!
Put the X30 on and will break it in next weekend sprint racing. The Rotax is in a box up for sale. I will take it and have it checked and resealed with a new passport. Thanks for everyone’s help at Willow Springs tring to get it going
