Aye Tom - sounds logical - as remember everyone thought I smacked a piston when my cam chain slipped - and maybe they did - but upon inspection with micrometer they were all within specs - albeit a lot of carbon build up on the valve heads - so after taking them out and cleaning and grinding the valves n' heads - the ol' girl purrs with just a very slight tap - but surely they tapped a little even when new ...... now, the one thing you mentioned is that it slowly lost power - which is puzzling - as mostly these things quit suddenly - with a bang ....... so digging back into my experience column - well I've only had a couple complete seizures - "Honda 750" and ol' "Jawa 450" ..... both of which were piston related ......
Anyway, keep me informed and I'll try my best to help where I can ... leastwise, with incouragement to carry on - as you got one really nice ride !!!!!!
Cheers, n' Happy Trails Ahead,
Bryan
My oil pump chain was very loose - and hate to say, but just maybe you forgot to tighten a bolt when replacing the oil pump - (it happens) - so re-trace your steps as surely think it's more likely something you've just worked on - speaking of which - I also forgot to tighten the oil drain bolt on my rebuild - but after seeing a small puddle of oil on the floor, at first thought a bad gasket seal, but followed it back and saw I had only hand tightened it ........ also had a leak in the o'ring line near the water pump - so took it apart again and saw it hadn't seated properly - so again, it happens mate - and just take your time and double check your work - which on the bright side, at least now you know the motor will turn ..... though always leave a little space on your tappets ........ otherwise, after my triple bypass rebuild - I'm gonna play the bike as new - and only ride real easy for at least 500 miles ..... along with changing the oil a couple times in between ........ so wish me luck - as I surely wanna get in a couple rides this summer ......
Cheers,

Thanks Tom - I'm planning on taking my bike out tomorrow - as shortly I'm off to the casino with two women, so imagine I'll continue drinking and partying till the wee hours again (so best to walk) .... and personally I'm still thinking it's something you've recently worked on - oil pump or water pump issue ...... both of which are easily accessible ...... yet if it's the camshaft - well you know it's a bigger job yet doable ..... otherwise, I don't believe it's your pistons as then it would continue to seize the motor tight - albeit maybe your valves also need a checking ....... ah what fun it is eh !!!!! Just remember we're all rooting for you to succeed .....
Aye Tom, five seconds on a cold engine should not overheat (regardless of water or no liquids) - so must be something else - and believe you probably should think about tearing it down ........ speaking of which, I don't know if there's such a thing as overcleaning the engine - but my sparks seem to have found oil - hence: maybe thinking I could have cleaned the piston heads too much, or as most everything inside is new, it may take a few miles to start carboning up again ...... anyway, it's sounding sweet, n' seems to respond to my (albeit stationary) reving for 15 minutes at a time ....... as I want to slowly break in the new parts without any extreme loads ....... so overall, it's getting close to being "On the Road Again" ...... and truly want to encourage you to keep plugging away - and keep us informed on your progress ........ damn - it was such a nice day here - would've been great to check out the new styles of bikini's at the beach <grin> ...... oh, well, summer's just starting !!!!!
How's the flywheel bearing look ???? Just a suggestion - but why not clean it in "Seafoam" while you have it apart .... also the oil pump chain looks a little loose ??? - not much adjustment on them ..... aye, I'm a perfectionist - but think it works better after a good cleaning ..... speaking of which, had mine out tonight for a little 10 mile run and worked pretty good, albeit still have a little fine tweeking to do on carbs -
Cheers, n' keep us informed .....
So sorry to hear about your wife's illness ..... n' totally understand priorities - so I'm hoping that it's just a small cheap part that broke and binding the system ...... hence: a bearing or pushrod (I have spares that may fit?) ...... otherwise, there's always a hard section to turn due to compression - so after you take off your lower heads - it should turn easier - as well as reveal the problem ....... otherwise, aye two bearings on the cam ......
Take care,
I did not remove the heads. I only did a visual inspection of the cam that was installed. I will investigate further tonight.
Tom
Thanks for all the good wishes. I feel confident I will find something. Yea you called it Bear, I guess Bob is NOT my uncle.(grin)
Hey Tom, What year and model is your motor ? Also what all do you need to bring it back to life ????
Cheers, with Happy Trails Ahead,

I believe in giving a hand to those in need, but I also believe people appreciate what they have more when they have earned it. Again, a thousand times thank-you, but I'll take care of it. I am going saturday to a salvage yard to see what they have. Now stop it before you make me tear up (again). Thank-you, Tom
I'm still a bit in the dark Tom ....... what do you figure you need to fix your engine ..... pistons, rods, & crank (anything else) OR do you really think you need another motor ???
As for gas - well I never dreamed filling my little tank would ever cost $15. - but it happened .... ($1.45 / litre) ...
Bryan,
The motor is totally shot. It would have to be totally rebuilt. New crank, rods, pistons, bearings, timing chain, oil pump,oil pump chain..................... and all the associated gaskets, along with the necessary machine work (heads, valves, bored etc). I think a low mileage motor, needing freshened up is the way to go. By the way, I never noticed it before, but there is no washer or spring in my oil filter housing. Don't remember there ever being one there. Did not know until recently read on this forum that there was supposed to be one.hmmmm, interesting.
