MrWolf Posted December 26, 2022 Share Posted December 26, 2022 5 hours ago, spikey said: I am once again puzzled by the things people do to bikes nowadays. What's with this business of wrapping fibreglass (?) ribbon round exhaust pipes? What's it supposed to do? Originally designed to deflect the heat back inside and out the end of exhaust pipes and to quieten them down, nowadays they are used on retro customs to hide rusty old pipes or seriously amateur welding long enough to flog the bike on eBay... 1 1 1 Link to comment Share on other sites More sharing options...
Kickstart Posted January 3, 2023 Share Posted January 3, 2023 Well, the FZR600 started and ran yesterday. Although the word "ran" might be a bit generous. Exhaust temperatures are all over the place, which suggests the left 2 cylinders are running, and the right 2 are only occasionally contributing. Carbs have been apart loads of time. Coils and leads measure up as pretty much in spec (one cap is slightly higher resistance than spec, but not much out) All the best Katy 3 Link to comment Share on other sites More sharing options...
Kickstart Posted January 5, 2023 Share Posted January 5, 2023 Bit more of a look. Cylinders 3 & 4 are certainly not contributing much. I checked the float height on one carb last night. On these downdraft carbs you check the float height by instead checking the fuel level in the float bowl, which you do by attaching a clear piece of pipe to the float bowl drain and then opening the drain screw. Did this and the level was way too low. I cannot find a figure for the actual float height. I took the needle valve assembly out again and looked at the needle. Realised that the replacement needles I used are ~0.5mm longer than the ones I had replaced. This is presumably messing up the float height. So looks like the carb rebuild kits were rubbish. I have ordered another rebuild kit from a reputable supplier. Fingers crossed. All the best Katy 3 Link to comment Share on other sites More sharing options...

Kickstart Posted January 9, 2023 Share Posted January 9, 2023 The FZR now runs! The carbs now need balancing, but I have managed to lose some of the adaptors for my vacuum gauges (my fault, knocked over the container - I have found 3 of each size but not the 4th!) It isn't charging the battery, but to be honest I am not surprised as I have a feeling I swapped the regulator / rectifier from it onto my TZR250 when that one failed (they are common to loads of Yamahas). Getting the airbox back on is proving to be a nightmare. The rubbers from the carbs to the airbox have shrunk and hardened, and I can either get them to stay on the carbs or in the airbox - but not both. I have left the attached to the carbs for now, and will leave them there for a few days to hopefully regain their shape a bit - then glue them to the airbox. No pictures - I have a video but can't upload that here. All the best Katy 5 1 Link to comment Share on other sites More sharing options...

IWCR Posted February 6, 2023 Share Posted February 6, 2023 Battery? Cant see a magneto, the cylindrical thing below the handlebars may be a coil, a spark plug lead is behind this and a lead coils down the front downtube and disappears to somewhwere on the engine, likely a contact breaker.

rockershovel Posted February 6, 2023 Share Posted February 6, 2023 I assume its a velodrome pacing machine. They seemed to be pretty scary.. I suppose because a racing bicycle was probably faster than a conventional motorcycle of the day. 1 Link to comment Share on other sites More sharing options...

Kickstart Posted February 13, 2023 Share Posted February 13, 2023 Hiya Still slow progress on the FZR600. Mostly done. Rear caliper is currently soaking in acetone to degrease it prior to cerakoting it. Then it can be reassembled and put on the bike. However the engine is being a big of a pig. I have had to take the plugs out, get them clean and hot with a blow torch and put them back in to get it running, and even then once running I would strugle to keep it running. I think I have found the major issue. When I rebuilt the carbs I replaced the pilot jets with those from the rebuild kit (the originals are a pain to get out, and easily damaged when doing so). I took the float bowls off on Saturday to check the jets, and took out the new pilot jets. On inspection they appear to be significantly larger than the original ones. Which probably explains why it was running horendously rich at idle. Swapped them out for some from a spark bank of carbs and had it idling OK, and balanced the carbs. I briefly started it on Sunday morning without a problem. But think I have flooded it again (as I couldn't get it to start later yesterday). Either way, it is getting there All the best Katy 3 1 Link to comment Share on other sites More sharing options...

There is a whole jungle of chinese-made bikes in the 125 to 250 range based on old Suzuki designs. They often have left-side exhausts, hence the crudely welded stainless leg-burner here. The drum front brake and clip-ons halfway down the forks are "kewl". Same applies to the inverted levers. Sometimes they appear under half-forgotten names (I saw one badged as a Francis-Barnett a while ago) but they are all much the same. 1 Link to comment Share on other sites More sharing options...
