This is one of the newer 47mm Metrakits for flat reed, with the Airsal piston and lack of Metra markings. I've had it on the shelf for a little while, and just decided to put together a different setup.
Never been installed/mocked up/anything. New and complete. Goes for $150 shipped on 77 and Treats. https://www.treatland.tv/derbi-variant-metrakit-70cc-kit-p/derbi-metrakit-70cc-kit.htm
I'm asking $130 shipped, and I'm also offering the following bonus items to entice you into buying it:
-Two long brass M6/10mm exhaust nuts
-Universal exhaust bracket
-Dellorto main jets 91 and 93
Free with da kit. I need monies for some other parts and a new pair of moccasins. PayPal address is the e-mail in my MA profile. Include your address with the payment. I ship quickly and I'm not a butthead. Thanks
