I bought the stage III mounting kit & used a Honda GXH50 four stroke engine.I am very happy with the kit.Every piece was in very good condition.I installed it on a Schwinn Point Beach cruiser bicycle and I sent a picture to this web-site that you can view in the bike gallery link.The customer service with the people at bicycle-engines.com is excellent ! I used a billet aluminum throttle,dual L/H side brake lever,bypassed the clutch(Not needed with a centrifugal clutch),fabricated a custom aluminum throttle assembly to bypass the stock governor,shortened all the cables & bent the chain tensioner in a z shape to better fit the chain line.I also used a 1 piece crank from bicycle-engines.com & mounted the fuel tank on the rear bike rack.I sealed the gear box with a thin line of black RTV & used transmission fluid-no leaks :-) I have a Schwinn speedometer also.The bike is alot of fun to ride & starts on the first pull every time! I have many more moods planned for the bike.

The mounting kit i ordered for $160 + $30 shipping was a steal. great quality mounting kit. the kit does come with the twist throttle with the double brake cable lever pull brake along with a killswitch. muffler was in fair condition but i would reccomend aftermarket high perf. gas tank paint job was in fair condition, many runs but not that i care. pretty much every other part was in excellent condition, the sprocket and mounting kit were beautiful. the grubee gearbox was in great condition, much better that that chinese 2 gear junk. I mounted the gearbox on a honda GXH50UQXA and the shaft was about 2mm long so i had to file the shaft lock screw. other than that everything worked out well. great quality from Bicycle-Engines.com. would definately recommend to a friend. thanks Bicycle-engine.com for you great products. Jon
