Went out in the sunny high wind weather the other day - got to 40mph on the flat wind assisted, but 15mph coming back! That is just too slow to be safe, so the wasp is booked in for a spot of tuning work - DR 102 cylinder kit, clutch overhaul, 16mm carb, Polini exhaust, gearing tweaks etc. Will give plenty more torque and a 15mph speed increase - enough for me what with the primitive brakes and suspension.
Was originally going to go for a 133/135, but that would mean the engine would need opening up and the crank replaced, plus clutch and electronic ignition fitted - was quoted an eye-watering amount for that from another workshop. The work I am having done, plus the cost of shipping the thing there and back, is a third of the 135 quote without the shipping.
