ESP Modified 30.5cc Big-Bore Combo Kit 4 HP w/2mm Crank
ON SALE RRP £134.99 - Reduced to £115.00
ESP modifies this cylinder by machining at the head. The stock 36mm cylinder does not have room for the longer crankshaft in this kit, so ESP has machined out the proper spacing. This is a more efficient and reliable solution than stacking gaskets to achieve the needed space, as there is proper spark plug clearance and the piston ring remains in the well-plated area of the cylinder. The squish band is cut so there will be .020"-.025" of squish (using the stock .020" cylinder gasket) and the combustion chamber is machined to get the compression ratio down to 14:1 for running on premium pump 91 or higher octane gasoline.
For Scooters: Fits any scooter using one of the above engines. Fits Sport, Liquimatic, Bigfoot, X-ped, Super X-ped, Super Bigfoot, Go-Quad, Super Go-Quad, Go-Quad 30, GSR26R, GSR29R, and Homebuilders Kit.
For R/C: Fits a wide variety of 1:5 and 1:6 R/C cars, planes, boats, and helicopters. Same mounting dimensions as Zenoah G230RC / G260RC. For cars - fits FG: Marder, Leopard, Monster Beetle, Monster Truck, Stadium Truck, Pajero, HARM, Sportline, etc. Also fits Smartech Traveler, Duratrax Firehammer, XTM, Carson Attack, HPI Baja 5b, and most other large scale onroad and offroad RC cars.
Note: Installing the crankshaft involves splitting the cases. The crankcase gasket can be re-used if in good shape, but will often need replacing (available in our gasket section). Also, check your crankcase seals (also available here at Abbots RC), as they sometimes need replacing as well. The crankcase bearings are usually fine to be re-used but it is wise to check them before installation.
