  1. Changed the seat pan to something I made that fits the frame. The picture of the old seat shows the mismatch from where I cut the frame to cove the seat. This looks much better and once I upholster it it'll be comfy Sent from my iPad using Tapatalk
  2. I filled the ports with mineral spirits from the parts washer where I worked. Held for 6 hours. I haven't tried to start the engine yet because there's so much more to do Sent from my iPad using Tapatalk
  3. Best part of being unemployed is that I can work on this whenever I want! Sent from my iPad using Tapatalk
  4. anyone know what kind of brake would fit this? I was going to weld some tabs on but now I'm even send guessing that decision Sent from my iPad using Tapatalk
  5. I extended a fork as far as I could, cut the tube then tapped the piece that was still in the lower down. There was a lot of the old seal still in there. Once I cleaned it all out I found the bushing is stuck to the lower. It's a total loss. I've tried for two days to get the bushing out and it's stuck. I'm looking into a stock brake caliper for this front end but now I have another problem. None of the calipers for a 74 CB look like they will fit on this. These are very weird forks. They have no tabs just some drilled and tapped holes. The guy I got the forks from didn't know what they came off of but a triple tree from a 74 CB fit and he said it was a CB so that's what I ran with. Sent from my iPad using Tapatalk
  6. I got a set of cbr front forks that I'm trying to take apart. I want the lowers to put on my cb750 project because they already have bosses for the calipers. Also I got then for free and am trying to do this on budget. Problem I'm having is getting the upper tubes separated from the lower tubes. The bolt on the bottom was rusted so I had to drill it out of one, the other came out fine but neither forks will come apart. I carved out the seal as much as I can and soaked them in pub blaster thinking the washer rusted into place. I even filled the inner tube with ice to try and get the upper to shrink up a little. My conclusion is the uppers must be bent. Is there any way to get them out? I have no use for the upper section so if someone suggested doing something that would sacrifice them I'm okay with that Sent from my iPad using Tapatalk
  7. Alright it's been a minute since I worked on this. I got a job and then I quit it and we moved so I wasn't able to do anything to this project except move it from the old house to the new. I got the head taken care of and have it slapped back together. I spent today trying to put new bearings and races into the neck. Has anyone replaced the bearing races in a 71 CB frame? The top race fits in super sloppy and the bottom doesn't fit at all. I put the races in the freezer and heated the neck with a torch but it still doesn't fit. The front end didn't come from the same place as the frame. The front end is a 74 and the frame is a 71 but everything I can find says it'll work but it's not. Sent from my iPad using Tapatalk
  8. A different power plant has crossed my mind, if I do I'll want a v motor to keep the profile tight
  9. I'm more concerned about the pitting on the combustion chamber of #3. I still need to clean out the runners because there is buildup and god knows what else, sitting in there. I'll get some solvent as part of the cleaning and check it then
  10. That's funny because in school when they were teaching machine shop they specifically had us use water. I used water before and it failed so I know I've made an improvement.
  11. pulled out the valves, used some scotch bride and tranny fluid to clean the valve seats since they leaked on previous inspection. Then cleaned up the valve face and lip and the combustion chambers. #3 is the worst and has some pitting in it. I cleaned up what I could without removing material from the chamber. Then I checked the valve lap, shoved a valve in and filled it up with water. No leaks so I think the lack of compression was the amount of crud on the valve seats and valves. I'm going to check the rings and cylinders while its apart but if I to do anymore to this engine I might just slide it to the side and get a 750. This is a lot of work for a $40 engine.
  12. Shit
  13. I ended up jb welding a piece of metal to fill the spot. Worked fine but now the engine has some issues so I gotta work on that
  14. Compression is shit. Either bad valves, rings or timing. I don't have a leak down tester so I'll have to do it the old fashioned way.
  15. Anyone got any ideas how to fix this? No I don't have the broken off piece. I jb welded a small piece of metal on to the gap and am letting it setup but I'm not very hopeful. The cable falls right out when I roll the throttle
