onesea Posted October 6, 2023 Share Posted October 6, 2023 Ok I have a 2007 CBR 125 as my fault commuter. Start with spark plug, mine went from running fine to rough starting & cutting out in 30 miles. After 2 weeks standing. Changing the spark plug fixed it. If the bike has full fairings they could be worth more than the bike. Try spark plug first see if it works, then look to service the rest. Atleast parts are cheap, and they are simple so good for honing mechanical skills. it's carb so even as dead bike has value. If you get it going they are quite fun to ride.

husoi Posted October 6, 2023 Author Share Posted October 6, 2023 Unfortunately @onesea the bike is one of those bad deals. The fairings are tied with cable ties of electrician isolating tape. Not even worth considering repairing and spraying when you can get a set + tank for £400 including fixing bolts. The park plug seems okay but mix is probably wrong and the carb needs out and clean.

Street fighter is the way most go. 1 Quote Link to comment Share on other sites More sharing options...
husoi Posted October 16, 2023 Author Share Posted October 16, 2023 Update on works So the bike started Saturday in the morning after being rolled back from the garage. Then died again and decided that wasn't starting again. Disassembling works started. Carb seems in a decent condition. The problem with the start is because of the choke being broken at the connection to the carb. Other damaged items, the fairings seem coming from a war zone. Half the fairing bolts are hex 8mm head instead the normal allen. Forgot to take pics of the bike, will try to get some later today. Yes, I know we all love pics 2 1 Quote Link to comment Share on other sites More sharing options...

Mine can be a funny bugger when it’s cold, it needs choke for a minute or so but don’t leave it on to long it won’t like starting at all.

husoi Posted October 17, 2023 Author Share Posted October 17, 2023 Carb and the choke connector. Fairings will need quite a lot of work repairing them. Most fixings are completely gone. There will be a lot of plastic welding to get them in order. Read some bad reviews on resin repairs. Hence welding as option. Quote Link to comment Share on other sites More sharing options...
RideWithStyles Posted October 17, 2023 Share Posted October 17, 2023 Was the cast on the edge of the connector broken before? Quote Link to comment Share on other sites More sharing options...

That's exactly how it was removed from the bike. Not sure if the black cover is just a protection that can be replaced with some shrink tube. Will report once I get the chance to work on it.

I've had some success with Plastex - including the fixing tabs. The hard part is keeping the moulding putty warm enough in this weather when I have to work on the driveway. https://www.plastex.net/How_To_Videos.php 1 Quote Link to comment Share on other sites More sharing options...
