I wll save you a little research time.......
The "Hoot" isn't known for long term service.
There are several "Hoot" versions......
Original gear drive [called figure 8] and it is a toss up rather the clutch or gears give up first.
The single chain primary version was also known for cutch issues and chains breaking or jumping the sprockets.
The double chain versaion is also famous for clutch issues and both chains causing problems [hitting the inside of the case, etc.].
Some have made an internal chain tensioner for the double chain version, but haven't heard of many success stories yet.
Bad news is the design of the system doesn't allow for the better drives to be attached to solve the problem. The motor has a very short tappered crankshaft and limits the ability to upgrade to a good clutch.
I guess the most important question is ........will a "weed-eater" style clutch survive usuage on a motorbike for long periods of time?
"Weed-eater" style clutches normally connect quickly [like an on-off switch] and don't allow the motor to glide into clutch lock [like an automatic transmission automobile], and requires the motor to be geared into the "Twilight Zone" [25 X 1] in order to make it work correctly [10,000 RPMs @ 30 MPH].
I am sure there are "weed-eater" style clutches that are slightly better, but a better clutch will most likely "stress" the balance of the "Hoot" drive components.
Best to put it together, ride as much as possible [don't stray too far from home], and keep comming back to this site for help in patching it together to extend the life cycle.
If the motor had a normal output shaft [5/8"] there are several companies that could help, however with the tapered shaft and in-board clutch, you will be limited on upgrade options.
Have fun,
