How much for an engine rebuild

So I am starting to think that my PO was talking shit when he said that he had the CB360 engine rebuilt. After a 15 minute ride, my breather tube puffs out white smoke like a 2-stroke, and my compression seems to be down from the last time I checked it out (used to be left: 155, right 160 and now: left 140, right 150).

This might be a case of me freaking out again, but how much $$$ would I expect to pay to get an engine rebuilt professionally? Who would you guys recommend for the job? I would probably be looking at putting in new piston rings as the minimum, and I have a NOS cam tensioner (upgrade from the recalled one...I didn't see the two stamps in the VIN saying that the swap was made). Once again, I am going to keep testing to be sure its the rings and not the valves, but I would like to know how much for reference.

Yeah I heard that 120 psi is the BARE minimum needed to run an engine decently. I just checked the oil level and I definitely had way too much in there (the dipstick was covered about a half inch above the top "fill line".

Krukster, Get yourself on the ChiVinMoto email list. There are a bunch of vintage Honda people that would be a great help to you. Networking parts and services, plus the social aspect. Also, Strats ( yeah, the place where CLSB used to have their bike nights on North avenue) is starting a vintage bike night every awednesday starting this week.
Also...This Wednesday is the second Wed. of the month and that means Chicago Norton Owners Club meeting at John' Pizza in on Lake street in Addison, less than a block east of Addison road on Lake. You should stop by the CNOC meeting. If you come about 7 the lot (on the east end of the building) should be full of all manner of vintage bikes and your Honda will be welcome. ChiVinMoto people will be in attendence as well, and you could meet and acquaint yourself with them.

"Dirt is for racing on...Asphalt is for getting there" OR "Flat trackers go in deeper and come out harder... OR (With apologies to General MaCarthur) "Old motorcycle racers never die, they just slip off the groove and fade into the dust!

If you want to anger a conservative, tell him a lie. To anger a liberal all one must do is tell the truth!

I have a bike in the shop now that has no more than 60psi in any of its four cyl.
Yet it runs (hard starting) which is the first sign of low compression.

Most often as I've posted before burnt valves are the cause.

120psi is a good # to look for. But by no means a bare minimum for running. Some low compression machines such as old BMW's and Harley's weren't any more than that for sure.

Its cool guys, these old bikes are a love/hate thing for me. I love it when it is running well or the work I am doing on it shows through, but when it takes a dump on me I have to walk away from it for a day or two before going back into it. At one point I was considering selling it, and look it is still in the garage LOL.

I think I was just overreacting and at this point if I had to rebuild, I am pretty sure I will do it myself.
