I'm pretty sure I got the crud out, figured I would throw out how I did it for everyone else. I actually took my shop vac and duck taped a plastic tube that would squeeze through the top end and into the case. I used a quarter-sized hose that was able to create good suction in a larger area, but...

I I'm back with an update! After needing two attempts to get the crank case to seal properly, I had to bust the case apart again because I went to loosen the chain tensioner while getting the cylinders on and thought the washer had dropped off and into the case. Never found the washer in the...

So in talking to a manufacturer of aftermarket rods and other performance parts, he had this to say: "You can never go wrong replacing the bolts when they are available, however the stock bolts can be re-torqued a few times without danger of them failing. Unless you have mega miles on your...

Absolutely no luck on finding the bolts any where. My options as I see them now are just hope the bolts will hold or buy new rods that will include the hardware. Digger, do you or anyone else know if the con rod bolts from an older SOHC would work? That would mean I could possibly buy the CycleX...

Ultimately only two of the 10 main bearing for the crank have green, the rest I cannot tell. They are showing copper-colored wear, so I am going to replace them. I am now curious as to if I should be concerned about replacing the cap end bolts and nuts for the rods, is this a concern, especially...

Thanks dirtdigger, exactly what I needed to know. I went to reassemble the engine this weekend and discovered that, quite unfortunately, my main bearing for the crank that go into the lower case were knocked around on my work bench. I cannot be 100% positive that they are in the original...

Also, sorry to blast so much info and questions, I'm just very nervous about this engine going together properly, hate to do all this work and it blows up in my face. Any advice as far as if I need assembly grease? Should i prime the oil pump with it or Vasoline, changing the oil after running...

With new carburetors out of my price range for now, I am still wondering if anyone has advice on jetting and such for the big bore I did. The primary jets are still the 68's, I'm guessing this might need to change? I bought off brand secondary jets, I know they may not flow the same as genuine...

I finally got my heads back from the shop and am getting ready to reassemble this weekend if I find time off of the restaurant. AussieCBNut, I would say if there is anything I regret it is not taking enough photos of hows things were put together. I would usually take a few photos, take...

What I've done/am doing: I decided to replace all gaskets in the engine and all oil seals, as well as fully rebuilding the carbs. I purchased a small ultrasonic cleaner for the carbs and broke them down and am about to reassemble them. For the engine, I decided since I did all the work of...

First off, hello to all you CB750 gurus and wrenchers, glad to join the conversation over here on these beautiful bikes. I also appreciate in advance any and all help and advice, and hope I can help others moving forward, too. I bought a 1980 Cb750F as my first motorcycle, quite honestly with...
