Greetings:

Great job and good pics, TVR. Not only the painstaking work to adapt this beast into the Spree, but overall effect is clean, nearly stock-looking. I particularly appreciate the Power Bulge in the side plastic for the carb. Well done.

Thanks, It was a lot of work to pull off cleanly. I guess I could have taken the easy route and just cut out the plastics.

With some tuning you can get decent performance out of a CH80. My daily commuter CH80 responded really well to rollers, intake and jetting. Had the same problem finding an aftermarket exhaust so still have the stock pipe and header. I know its frowned upon in these circles but a simple blue CDI really unleashed my CH80(and BBK AF16).

Excellent work and great looking Spree.

Care to share the specs of your setup?

How much of the ch80 was "unleashed" after the cdi? Did you test before and after?? Ch80's are tough to get reliable performance out of, so small findings like this, if in fact it does improve performance, are crucial for our ch80 crowd. I feel like I should start a thread soon for ch80 modifications and results

Excellent work and great looking Spree.

I completely agree. Looks super clean.

I actually bought and installed a "new racing cdi" and performance coil recently. I didn't notice anything different, except it smoothed out a tiny misfire at idle. But maybe any brand new cdi or coil to replace the original 30 year old electronics could have cured that. Someday if I really mod out the ch80 it might become useful, they say it has no rev limit.

That very last picture is the burned down taylor electric building in se portland right? I work right there i almost took my ruckus in there for pics.

I have no idea what building that is, it's a few blocks down from burnside skate park. I wanted to get inside the fence but decided it wasn't worth getting hassled for trespassing.

Small world. I work for oregon electric right next to that spot. I wanted to get my scoot in there real bad. do you live in se?

I live farther east, deep into Gresham.

I made foot rest pegs, holding my legs together on a small spree floorboard gets uncomfortable on long rides.

Since the swap I've put over 1000 miles on it!

The riding season here is kinda short, gotta take advantage of the dry days.

I took the variator off my spare ch80 engine and decided to try a mod. I shaved out the roller weight ramp so they can move further out. People have done things similar on other model scooters, they refer to it as notching the variator. Unfortunately it didn't work out and gave me a flat spot in my acceleration, tried some different weight combos with no good results. I wouldn't advise anyone to try it, I put my unmolested variator back on.

Wow I was thinking of doing that with my aero 80 last week but decided not to with out having gotten another variator to try it with looks like you did the same thing so smart The moped guys do that to the Honda hobbit pa50 variator but what they do is actually cut the wall out completely at the end of each ramp. http://outofcontrolmopeds.blogspot.ca/2 ... ching.html I wonder if you could save that variator doing that, because you could polish each ramp smooth so the rollers won't catch and cause your flat spot in the acceleration.

I thought about cutting out the end of the ramp, but figured it might be too much. It was experimental, now I'm thinking about modding a variator from a dio or gy6 to fit my ch80. But it's a gamble, could be a waste of my time and money.
