.... to the mechanics in the group

.... If you were to buy a bike, and you were told, that the motor had some work done to it.
is there anyway you could check the size of the bore or cc's without removing the head.

dont have to be a mechanic to answer that,,,,no

lol.... yes there is. paperwork....

if they have zero paperwork, suspect! it's on THEM to show proof if they claim something. if they can't, disregard the claim and assess as such.

Agreed. If I spent money on boring a motor or new heads or whatever. I'd sure keep the receipts for proof of the work done. Just in case I ever sold the bike.

If they tell you it has engine work and they can't produce receipts, RUN AWAY from it.

[ideajones]

If you could blow up a balloon thru the spark plug hole maybe?

[brook]

.... No paper work,............................[this is just a thought]
how about this, remove all plugs, using a thin stick as a gauge to measure the #1 piston at it's lowest point...... Then using a measuring bottle with trans. fluid, and measure the amount of fluid that you put in the cylinder. So now you know how much fluid that the cylinder holds [x4]. Now, just need to know, how many ounce's equal a cc.... is that possible??
need to know if it is with in 30cc's, of what was said.

hmm, that could work. get the #1 piston bottom dead center on the compression stroke. Put in one of them fake spark plugs used for pressure testing / leak down testing. Get a 5gal bucket of water and a 1 liter bottle. fill bucket and bottle completly, have someone hold the bottle filled above the waterline of the bucket but so that the neck of the bottle is still submerged so that the bottle is still 100% filled with water. then place tube from fake spark plug into neck of bottle. SLOWLY TURN the motor till you get to top dead center. the air will displace the water out of the bottle where you can mark the bottle where the waterline now is.

THEN you can fill the bottle till that line, and FINALLY pour into a graduated cylinder of somekind... this will get you one pistons worth of cc's... x4 walla... should be pretty close.

That said, what is the deal... what bike, what work is said to be done, how much. Like others have stated if the person cant produce paperwork then id be weary.

wow nd4spdbh.... sounds like way too much work. i would just simply say "no paperwork? no deal." that simple. anyone can claim anything, including dumping tons of money into it but claims are like assholes, everyone's got em.

99% of the time i would say the same thing... but we need to hear the OP's story on the bike... the price etc etc.

[secondchance]

what kind of bike we talking about

[brook]

.... nd4spdbh, that is pretty clever!!
about the bike, it is an FJ, same year as mine. It runs, but it is damage from a wreck. I am looking to buy it for parts [cheap]. it is only good to me, if I know the size of the bore.

thanks for the comments

[bocomomark]

My two cents: If you need to know the bore, you'll have to pull the head. Anything else is just a guess.

[Dev]

I'm not a mechanic, but my hair dresser told me to check compression if you are looking to buy a bike. Again, my account told me, then everyone looked at our table, he said, and I quote; 'If there is a 10% difference between cylinders, you don't need to see paper work, you need to walk away from that piece of pie with my cough fee.' And with that, he left me the lunch bill.

[jaryl21]

Well I guess this thread lets us know who are NOT mechanics...lol

[Spade115]

Even with paperwork it can be said its done to this bike and actually done to another your best bet is to pull the heads and check them properly if it was dumped/wrecked it could be the work done to it is what caused the problem. dropped piston or something. You might as well check it right the first time. See if what you would be salvaging is worth what you are looking to get befor buying also depending on the wreck will give you an estimate of how much damage it actually got.
