Hi Jaguar,
I have bought one of your CDI's and I'm very happy with it but not sure which jumpers to use, I have left it as it came, but I'm thinking maybe I should be using the B2 jumper but not sure, your instructions say: use what runs best, but if we look at my setup, its a standard $129AU engine kit, not a grubee or DLL etc. it has an 16.16 Delorto SHA carb with a .793mm jet, a SBP expansion Chamber with a SBP muffler kit on the end, a rocksolid reed kit, a K&N type air filter, I ported the exhaust manifold to increase the flow into the expansion chamber, I fabricated and fitted a matched copper gasket, but the copper and silicon tube set up from SBP really needs to be replaced with one tube the right size and shape to keep the flow moving, which ill do this weekend, I have also fitted a jackshaft kit with a seven speed derailer, I shaved the head and completely removed the ring around the chamber, then fitted Stainless steel head studs and fabricated a copper head gasket, it has a B6HS spark plug, Ive ordered an iridium one from SBP, I have not done any port modifications, due to tightening the head too tight, the barrel wont come out without stripping the whole engine down, it runs sweet as it is and does 50kph in 4th gear, so far i cant seem to keep the revs up enough through the last 3 gear changes to get past 56kph top speed, in your opinion does this setup warrant the B2 jumper, and do you move the jumpers or add the jumpers? and thanks for providing us motoredbikes people with such a great CDI
regards,
Chookawatts
PS: my original Delorto (not copy) was and still is missing the float bowl gasket, and I have had to order one for it, not a very good Quality control team at Delorto!
