Great kit July 23, 2012
taco eater: Michael Sallie from Canon City, CO United States  
Instslled on 1980 lb50, stock exhaust, stock reed valve, lb80 carb from a 76, high compression o ring head.  Stock setup chappy was very slow at 22mph.  Kit is extremely easy to install in under 15 minutes.  Bike now performes like its big brother lb80.  Still under break in, top speeds have reached 36 so far and getting stronger with every mile.  Altitude here is 5500ft so I'm sure you low landers will see even greater gains.  I can tell this kit has more to offer with a pipe and still bigger yet carb. Not enough oooooos in taco to rate this properly. Get it! If you can start your bike you can install this.

polini kit June 21, 2010
taco eater: ivan lopresti from landing, NJ United States  
i just installed the 70 cc kit, my chappy has the gianelli exhaust on it, and i had the stock head shaved a few years back. now before the polini kit the chappy got up to 32 mph max. now with 70 cc it got to only 32mph but got there quicker, from 25 and up it was picking up speed fast, now at 32 mph my rear wheel locked up, i skidded a long distance. i thought engine was shot, but after it started up??? is there a break in period for this? please let me know thanx

I bugged benji for about a year to get this for me cause I didn't want to order from 50cc. Ports are massive, and it bolts up easy. Get the phbg manifold, and a 19 or 21 clamp on, malossi e12 and one of the 4-petal reedblocks. You have to file the intake a bit to fit, but it gives you more power. My chappy was a turd, doing 23 or so, but with the kit (carb, gianelli pipe, etc) it got up to 50 (i regeared too). Sounds great and runs strong, tons of low end. I have a 90-something jet and a big idle. Blasting chappys!
