Should have just taken a video.... ugh!
battery is too low and im not in the mood to push the bike to my car a 3rd time....

Bike just cranks.
No sputter, nothing. just crank crank crank

but my only worry is.
while its cranking, I can clearly hear a Thump Thump Thump everytime it cranks.

as if the piston is smacking the head.

not a ticking, grinding or anything, but a perfect Thump thump thump. (guess my bikes humping itself!) HAHAHAHHA  :cookoo:

Plan to check the timing and valve clearances again tomorrow.
but hope theres nothing wrong below that!

just put a Good 95 or 96 head on an 89 engine (89 lower end and cylinders + pistons)

anything to worry about?
or just the timing is off? (which I dunno how that would happen ><)

(edit)
I can only Hear it btw.
with my hand on the top of the engine, I dont feel anything hitting eachother.

Check and recheck the timing chain if you just had the head off.  Be sure the crank is at TDC and your timing marks on the cams are right when you mount the chain.  I wouldn't crank it anymore in case the timing is off before checking.

-My 2 cents.

Did you spin it by hand?  Anything feel unusual?

Does it sound like air passing thru a hole?  I would guess a loose exhaust - where the headers bolt up.

nope, it honestly went together, cranked, and all felt Great!

I'll recheck everything when I wake up tomorrow.

(edit)
yeah I'll check the headers.
I did those in a bit of a hurry.
because it was POURING!
and I got quite drenched.

+1.....If you pull the plugs out you should be able to turn it over by hand with relative ease and "feel" any abnormalities.

Fwiw, headers being bolted up or not will have absolutely nothing to do with the mechanics of the engine. It will run without them, albeit not well, and you risk burning valves but none the less it will run. Tomb, I'd double check timing. Does it sound erratic? You can def tell a difference when its out of time or in time when cranking.

it sounds absolutely fine other then a thumping noise.

normal cranking noise and just wont start.

I'll take the cam shafts out again tomorrow and just reset everything after rechecking valve clearance Again! (tho I KNOW they were good!!)

if worse comes to worse...
I'll just replace the valve that isnt seating properly in the head I replaced and put that Back on and then get more problems... hahahahaha

(edit)
im tempted to go out and mess with it now.
but I just cant shake this mood now.
so I'll try to by killin some Zombies <3  :2guns:

dude, you have the worst luck ever.

Every time i read one of your new posts i feel like starting my bike up, pointing it in your direction, put a throttle lock on, and watch it fly into the sunset, or rise, or no sun, depending on what point of the compass you are from me. With any luck, it'll get there and still be running.



or maybe it will get there, run, and then cease running the next day...   :icon_mrgreen:

didnt take them off.
was no need to.

heck, there wasnt any need to even clean the tops.
sides were clean and tops didnt have much buildup on them at all.


and yea Funderb, I've been saying that all along.
I got some bad luck! hahaha

but I wont be pushed around by even that!
Im not going to stop until this suckers fixed!

kk, up a lil earlier then usual.
work 3rd, was off and wanted more daylight to work so I went to bed early.

gonna sit here and catch my bearings, then go out and tackle this prick yet again!

^^^ haha tnx

well!
good news for the thumping.
+1 to Big Rich  :bowdown:  :thumb:

It was a loose header.
the right side wasnt fully pushed in.
So that thumping noise was the exhaust passing out the headers instead of through to the muffler.
which it is now doing.

sounds like a freakin heartbeat when the bikes cranking hahahaha... CLEAR!!!
We're losing her! hahah

still just cranks tho.

gonna go out in a min and check the valve clearance and timing again.

(edit)
fairly confident now, as my only worry was that thumping.

... see what happens when your in a hurry to do work?
started Pouring so I hurried and put the exhaust on......
<<<< Dumb@$$!!!!  :cookoo:

I honestly Pray it runs now when im done.
as my biggest worry was an oil leak.
and with all that cranking, I think if there was one worth worrying about, it would have shown itself by now.  :thumb:

got it started... sounded GREAT!
was so happy..... for a few Seconds!

YAY!
now im back to a previous problem!!!

F'er bogs and dies when I give it too much throttle again!
if I give it slowly, RPMs will raise.
but as soon as it nears above 5K, it bogs.
then I hear a gurgle or some kinda noise from the top end.
I forget now.

Im about to go take a video of it and upload it.
then take a compression test when the bike warms up nicely.

i'm curious of the condition of the stator. when my bike had a bad ground it would sit and idle all day. any input of the throttle would cause it to run like shaZam! instantly. rechecked grounds and re terminated a few and voila, back to 100%. when it would go haywire the headlight was flashing with the voltage spikes. has to be electrical at this point buddy, you've eliminated everything else. maybe the cdi is taking a crap on ya

dunno....
but the video turned out good.
can hear it quite clearly.

uploading it to FB now, so it will be a lil bit.

meantime im going to try and relax before going out for a compression test.
