Zenoah G260-26 cc Motor (FG7384)
Zenoah has been the supplier of RC 2-stroke engines for many years, manufactured in the large Kumatsu factories in Japan.
This solid G260 26cc engine has more than proven its worth, this 2024 version has been marginally overhauled to make optimal use of reliability and power. The compression ratio has been adjusted, which has clearly increased the power at the lower revs. The crankcase and crankshaft have also been slightly changed. The crankcase has been modified in such a way that the G230 and G260 cylinder sets can be used as usual. The pins of the crank shaft have been grounded to a slightly smaller diameter so that the connecting rod and piston can center optimally. The cylinder is attached with two bolts on this engine. The Zenoah G260 engine icomes without clutch, exhaust and engine flange.
For optimal use, we recommend the PSR-2 Race olie, and TPS™ Air filter system. All parts and tuning parts are available from stock!

Engine running in:
- 1) Use 1:25 fuel mixture, 40 cc good quality 2-stroke oil on one E5 fuel
- 2) Carb needles both 1 1/4 turn open
- 3) Start first time let it run at idle for 2 minutes until is had normal temperature
- 4) Run first tank of fuel normal but without reaching high speed, this will take approx 45 minutes
- 5) Let it completely cool down
- 6) Run second tank of fuel, now start reaching high speed shortly, this will take approx 40 minutes
- 7) Let it completely cool down
- 8) Visual check in exhaust port, check for leakage
- 9) Third tank drive it like you normal would do, but still reaching high speed shortly, but building, this will take approx 35 minutes
