Hi All, Just thought that I would share with you all the tuning of my Kisbee, and warn you potential Kisbee tuners what to expect when you open it up.The Kisbee has a new-ish variant of the popular 139QMB engine fitted. It is not exactly standard, and is nothing like the engine fitted to the V-clic. 139QMB-E points to note. If you want to fit a big bore kit to a Kisbee, then you will need a crankshaft too. The crank on the Kisbee has a 10mm piston gudgeon pin. Virtually every other 139qmb variant out there has a 13mm gudgeon pin in the piston. It does have, however, a standard 16 tooth sprocket oil pump drive, so no oil pump needed with the crank swap. You will need to change the cylinder head also, if you wish to install an aftermarket cam....The cylinder head is not standard. The camshaft rocker supports are cast into the head, they do not separate when you take the cylinder head nuts off. The camshaft is a two piece unit, separate sprocket type, which also makes refitting the cam chain difficult. The restriction for top speed is via the cdi. Fed via a sensor on the clutch bell. Easily bypassed with a soldering iron and short piece of wire. It comes with a DENI copy 18mm CVK type carb.....its not very good quality. I have binned it. This engine does not appear to like the Leo-Vince Titan exhaust in its current tune. I have removed it(saving it for the 90cc being built), and fitted it with the Naraku crossover (meant for the V-clic, but fits with a tiny bit of modification). It seems to prefer a bit of back-pressure. Current spec is 72cc naraku V2 big bore. Naraku CVK V2 Carb 38 pilot, 85 Main. Naraku Sport Variator with 6gm rollers. Naraku Torque Driver. Standard airbox, Naraku replacement panel filter, and additional 'uni' insert in airbox. Next bits to do are matt vinyl wrap, and an import big valve head from scrappydog scooters with an A9 cam. Cheers, MrC.
