2025年3月2日 · Hello all. I just purchased a 1950 Whizzer Pacemaker. It appears as if it is a complete bike, however, after going through all of the components on the Whizzer, I added new oil and fuel and cannot get the engine to fire up.

2019年5月21日 · I am going start building a new MB and am going to get a GRUBEE SkyHawk GT5B 69cc Angle Fire Slant Head Bike Motor Kit, These motors are new and built after 2020. I had a GT5a that blew the piston rings and I'm going to fix it with a new head and piston and save it as a spare, the 5a's were built according to the stamp on the motor in 2017.

Update 12/5/19 - used larger electrode and stand to position for largest sparks. Flames are much bigger and the exhaust gases light every time.

2023年12月11日 · I've got fuel, and I installed the kit on a bike. The ignition might be weak, but it's usual, and there's sometimes misfires, rarely. One day I even ignitited few drops of fuel inside the little 2-stroke engine with another fire in front of the exhaust, and it burned as hell, so that's the only thing that has worked so far.

2009年6月12日 · I thought i'de trial this as a heavy duty 2" tyre liner,either in it's standard form or cut in halves to make 2 liners. Really it's meant as a VERY high pressure water hose so it has to be tough as nails.Speaking of nails i tried piercing a nail through it & i must say most unsuccessfually;good. :D

2008年1月26日 · Good News about your bike Hi, I'm glad that you were able to fix your bike. These are great little machines, but there are a few little things that need to be known, and are not easily seen, like that silly taillite wiring crossover. Good luck with it, and if you need help, please feel free to ask. Mike
