103 exhaust screw fitted

Yesterday I got the new exhaust adaptor fitted. It was pretty straight forward and the screw fitting made it really easy to attach. Unfortunately the exhaust is still too loud so I will either go back to my old exhaust or buy something a bit more quiet.

Its been a while since my last post but I finally got hold of a screw in exhaust adapter. Hopefully this will solve my noisy and leaking exhaust problem.

Out and about on the 103!

Today was the first time ive got out for a proper ride on the 103 since doing all the modifications. Its was awesome! I did about ten miles and the peugeot didnt miss a beat. I got up to 39mph before it would get a bit boggy so I may need to lean the main jet slightly. Low end power is ridiculous due in part to the circuit pipe. I may be able to gear it for a higher top speed while still keeping the hill climbing ability. The Simonini exhaust is so loud it gave me a headache. I will look into repacking the silencer.

I spotted this carb on ebay and I thought id get it as the next upgrade for the peugeot 103 which currently has a PHBG 17. When I have a minute I'll pull it apart and see what atomiser/bushing and jets it has.

More 103 tuning

Today I fitted the Domino throttle on the Peugeot which made a load of difference as the old one had a stiff mechanism. I also replaced the damaged cluch bell. My crankshaft seems to eat through these pretty quick. Finally I had a bit of a ride to try and get the carb tuned. After multiple stops and various adjustment I think im almost there. One more session should do it and then I'll book it in for MOT.
