I have 2 engines with low hours 17hours & 16.7 hours, both have been serviced & rebuilt for performance by top engine builders. Both have been set up top & bottom by Dave Hark in NSW. 1 engine I have recently had top end rebuild done by Colin Moat and has 0 hours since rebuild (16.7 hours in total), I did this to compare engine builders performance & Colin is South Australia based & highly regarded & recommended. The other engine has approximately 4 hours since Dave Hark last rebuild. We have decided to get out of Karting and have moved into Hyundai Excel racing. Both engines are very strong & competitive, both come complete with exhaust, mounts & wiring looms, both engines have upgraded AKA approved rotors & carburettors. I also have original carburettors (these work better in the rain & cold weather) $100 additional cost per carburettor. Asking $2600 for each engine.
