I'd check the airfilter, pull it out and take it for a ride... um... drive? to see if top end speed increases. I'd replace the fuel filter, and check the fuel tank vent system, as well.

Found this: GY6 engine - Wikipedia, the free encyclopedia

Do the RPMs seem abnormally high for cruising above 40+? Wiki mentions its driven commonly with CV type carbs, this could be the reason why. CV carbs if not tuned properly could have demenishing performance results in the higher rpm range. luckily main jets are a snap to change out for better tunning

Air filter is an aftermarket foam thing im not excited about, Ill pull it off and see what happens. Changed the fuel filter already. Ill have to mess with the tank vent system.

It does seem to be rather high RPMs for the upper speed. I figured it was just the way the thing was geared. I opened up the carb once. its real simple and very basic.

Thanks for all the input!

There is no miracle : a 160cc engine must be geared pretty low to tow this much weight.

The CVT is setted either towards acceleration or top end speed (which would be stupid with a hauling vehicle)

Your contribution brings back thoughts of a quad based low streamliner (and then I recall that the main advantage of my bike is lane splitting induced reliability of my commute time ...)

quick update. Just small stuff for the moment. Need more choroplast and no way to haul it on the new rig

Enclosed the "Splashgaurds" and started to box in the lower cargo carrier.

looking good!

To get more chloroplast, try taking a sheet and strapping it to the side of the trike?

Finished boxing the rear cargo area.



Strengthened the "hatch" horizontally with Aluminum flatbar.

Secured it with Magnetic Cabinet latches.





The little metal pieces on the hatch (one on either side) don't fit flat against the magnetic catch so don't hold terribly well. Ill address this in future models.

She seems to have an easier time achieving/holding 45mph. Not sure if this is the result of boxing the tail, or more likely, from cleaning the carb. Haven't tried another Freeway/top speed run yet.

Want to address a wind buffeting issue first. Seems like wind is rushing around the narrow fairing and pushing me side to side. Not in a rush to close up the sides till I get the ride height down. This thing is tall and narrow. Unfortunately the wide cargo bay means lowering the ride height could cause lean angle issues. Beefing up the suspension will come first anyways.

Preloading the springs and thicker oil should help stiffen up the front end. Not sure what to do about the rear yet.
