I have the gs190 mounted in my aftermarket frame. I have made it to hooking up the carb. Anyone figured out an easy way to hook up a twist throttle to this engine? Would you use the governor or go straight to carb?

I need a longer axle in the front of a worksman wheel. The forks need to be wider to give room for the brake to be fastened. I beat on the axle with a dead blow hammer, but it did not budge. How does that sucker come out?

Looks like a simplex from a distance. Frame looks professional. Some welding, mostly brazing on brackets, ect.
Tank, center fill, 17 inches long. Longer then any simplex tank we measured.
Frame in rear loops around instead of two tubes terminating at the wheel.
Front forks are 1/2 inch, one piece all the way thru springs, larger then two piece simplex.
Crash bars extend under bike until they meet, and smaller diameter.
Drive train goes from belt to jack shaft, to chain final drive.
The engine moves on rails by pedal to tighten belt. A one way gear holds motor/belt tight until cable to handlebar lifts gear, releasing engine to slide back and loosen drive belt.
Brakes are on outside of drum and contract using pedal on right side. They look totally inadequate.
Rear sprocket is monarch super with bracing in three places to rim.
Handlebar controls are prewar schwinn.
Fenders are prewar schwinn.
Seat leather  is simplex.
Footboards are different, bigger and wider then my other simplexes or bikes.
No serial numbers to be found.
I added the Deco-Grand engine.
Bought at portland 2020 and payed too much,,,but i liked it so I don’t care.

Edited for spelling.

My speedo whined very loudly on my first ride today. Bike had not been started for 12-15 years. It went up to 35 mph, then back to 10, while really the bike speed did not change. I unhooked the cable to try and let it survive while i asked questions. Is there lube needed?
