Honda PA50 Pipe Experiments / Results
Proma Country Pipe (designed for a Puch)
OK, I was tired of waiting for a “designed for the Hobbit/Camino” pipe to show up (either for sale or used), so I decided to try grafting a cheap pipe onto my Hobbit.
I bought a Proma Country pipe (for a Puch) from mopedshop.com for $60 plus shipping.
The results are good. My town is full of hills. On the last ride (with the stock exhaust), my Hobbit would only pull 20 MPH up a certain hill. On my trial ride (no “dialing in the jet yet”), my Hobbit pulled 27 MPH!
Top speed? Don’t know for sure yet. I could only go about 28MPH (I weight about 250 lbs) on flat and level. So far, on a short straigt, it went 33 or 34 MPH indicated. It may have more in it on a longer straight.
From a stop, I think it lost a tiny bit, but once it is about 5 to 7 MPH, it certainly starts pulling harder than it used to. I’m thinking that I may lighten my variator weights some, since it seems like this would also help acceleration (the new powerband peak seems slightly higher than before).
Downside: The center stand does hit the pipe, preventing it from folding to the fully-up position. Not a big deal for me.
I view this experiment as worth while. If it’ll get a little faster when I match the jet to the pipe, even better. My goal was midrange torque/pulling power, and this goal was met.
One last problem remains: this mod means that I can easily outpull my sons Hobbit in town. He won’t be happy. I’m thinking about grafting a Technigas on his . . . .
LeoVince (designed for a Hobbit)
Just to start I would like to point out that my bike was performing properly before the Leovince, I could hit 30mph on a flat. I also used a gps to measure these speed.
I slapped the pipe on right when I got home from work. Does hurt the low end, but I usually peddle like crazy until I hit 10mph so it doesn’t bug me. Very good acceleration after 10mph. I hit 38mph on the longest flat I could find, if it was longer I think I would have gone faster.
I hit about 43mph going down hill but then I lost all power and the rear wheel locked up (soft seized I think) and I nearly killed my self (luck no one was behind me). I pull over and it fired a couple times then died. Started right back up about a minute later. I need to upjet, I advise everyone with this pipe to upjet or at least do a plug chop.
Here is the best part, I can cruise at 30mph with only using about 1/4 throttle.
A definite increase in performance over stock. I was hitting about 26, not sure if my 220lbs or a lack of cleanliness in the carb was limiting me. With the LeoVince, I’ve hit about 33. A +7mph gain from where I was.
I’m hoping a carb cleaning, and possibly new rings (125psi comp) might increase my performance even more.
Bottom line: The LeoVince Camino pipe is well worth it!
I never used the pipe on the stock setup (PA50 I, 20mph). Over the winter, I put a 70cc Athena kit, variator plate and wieghts, 21mm phbg kit, performance reeds and ported the block. Tuned and dialed in (96 jet) , it does 49-50 (chase car). It will cruise 40 all day at about 1/3 throttle. Stock gears. Gets about 45 mpg give or take. Initial take off is a little weak. i kind of have to push off with my feet but it picks up after about 5 mph and really starts pulling at 20-45. I weigh 205 so if you don’t exceed the bikes rated limits by 55 lbs, the take off probably wouldn’t be an issue.
Overall, I am very pleased with the pipe. Its built solidly, it looks decent, and performs awesome for my driving needs. Get one.
