MRRPM 1040 BIG BORE ENGINE

CORE INFO >> If you do not have a good rebuildable core (cases must be good) What we send you in your build is what needs to be sent back with your core minus a bad crank. IF YOU PURCHASE AN ENGINE BUILD YOU MUST ALSO SELECT A G1 OR G2 CORE FEE AND ADD IT TO THE CART UNLESS YOU WANT TO SEND YOUR ENGINE FIRST THEN YOU CAN JUST EMAIL OR CLICK MESSAGE US BELOW!<< All of my cases are bead or soda blasted. All of our engines include new, cranks, rods, pistons, cylinders, chains, oil pump, oil cooler-(except g1), main bearings, pto bearing, oil seals, heads-(ONLY R ENGINES), mechanical water pump seal, oil seals, gaskets. Depending on the build request some parts are oem some are not. Cranks will be oem used or new meeting spec or aftermarket. These also come with the flywheel, stator and cover.. Put your sensors, plugs, mounts etc on from your core, install, fill with oil and roll.

POWER GAINS > That is not a simple answer. It varies on supporting mods, clutching, compression, fuel and tuning. SOME engines we keep in stock but most are built to order. If we don't have what you need built we can build within a couple days we normally keep most all parts in Stock. All builds will come with stock for whatever base model cams of the engine you have selected but can add anyone's cams or heads for whatever their retail cost is just add them to the cart. Any build over stock will require tuning. Anything below a 800cc we do not build with we just turn them all into at least 800's due to cost plus it's more power for you.

PLEASE PUT YOUR YEAR MAKE AND MODEL MACHINE IN THE ADDITIONAL NOTES BOX AS WELL AS IF YOU ARE NATURALLY ASPIRATED OR RUNNING TURBO/NITROUS. WHAT FUEL YOU PLAN TO RUN.  ALSO IF YOU HAVE A COMPRESSION RATIO YOU ARE TRYING TO ACHIEVE PLEASE PUT THAT AS WELL. IF ATV WE NEED TO KNOW IF IT HAS POWER STEERING.

REMEMBER IF YOUR MACHINE DOES NOT HAVE MAVERICK HEADS OR A PARTICULAR CAM IN YOUR BASE BUILD (WHAT YOU HAVE NOW AND WILL BE SENDING BACK TO US) THEN YOU WILL NEED TO ADD THEM TO THE CART FOR THIS BUILD.
