We are in the process of cleaning out the shop/updating our inventory with new items.  We will be listing several used/spare parts in the coming weeks so be sure to watch our auctions.

This listing is for one ATVA National Champion Cobra Production 90cc RMC Engine.  This is a used 2013 Cobra CX65 bottom end purchased new in March 2013.  We had a stroker crank installed as well as the RM85 Power Valve Cylinder for $6500.  After the first few rounds of the ATVA National Series, we purchased a 2nd engine and took this one out of the quad to freshen up and make modifications to get more power.  We ended up changing the port timing, installing a PHAT Head with interchangeable domes (included & pictured), experimented with several different compression ratios, machined the cases, balanced the crankshaft, fine tuned the transmission, remapped the CDI, installed a billet water pump cover, and changed the Power Valve engagement point.  This is by far the fastest 90cc Production engine.  The rider that raced this quad was one of the biggest kids in the class (140 lbs geared up) and still won the national Championship.  There is only 3 race rounds on the engine since modifications have been completed (5 rounds total).  There is over $10,000 invested in this engine, not to mention the time invested in fine tuning & testing to find the extra power.  We will share more specific information about the engine as well as tuning tips and tricks with the final buyer only.  Auction includes the engine as pictured, plus extra inserts as well as the electronics that are not pictured.   This is a race engine and thus has no warranty.

**Online discounted pricing only good if purchased online.

If you have any questions, please send us an e-mail or call 812/673-4958.  We also have most Cobra and DRR models in stock including Cobra ECX-50 & 70 quads, Kings, CM, P3, CX65, and DRR DRX50 & 90 quads, etc...  Also have several used Cobra bikes/quads in stock.  *ALL USED QUADS/BIKES/PARTS SOLD "AS IS". 

Thanks for your interest.
