Cheers for all comments.

to sum up might be best to use my original barrel which isnt too bad scored really (ill have a closer look) as i know for sure that was running its original piston which should allow decent honing of barrel if required.

oil seemed identical color to that of the 2 stroke reservoir.

another way a guy on do the ton forum mentioned to check the seals is to prop engine up so that the crank opening is level, fill with parrafin (kero) leave overnight and check if dropped. small amount ok from evap but if half way gone then there is a def problem.

Ill do the checks re bottom end then take it from there in regard to doing top end.

not being too particular but would rather put a new top end in for the cash whilst its all apart etc.

Thanks again for info

Appears to be carbon from what I can tell.

Info from do the ton forum and Suzuki TS forum recommend, replace rings and keep piston though keep it below redline due to already scored skirt of piston so I think ill scrap it and buy a fresh seeing as though this one isn't a forged wiseco or anything worth trying to use.

now that i have sucked out the excess oil from the crank area is there an easy way to test whether the oil was from deliberate addition for preserving / oil line siphon in or damage ?

if i just fill the engine with oil via normal filling point and see if is seeps in ?

once i find out whether i need to fully rebuild bottom end (how oil got in / if damaged) i will move onto new top end.

Sorry for newb questions but what is process for working out size of next piston, vernier caliper on top / bottom of barrel, get average of many measurements then buy piston next available size up and get barrel honed ?

will use barrel and head off this new bike as my orig one would be in worse nick i think .

Cheers

Forgot to add this pic, piston does have one marking. 060 and the arrow pointing to exhaust.

guessing 060 is a marking in measurement of some description ?

Ok, here are some pics of the piston that came out of second bike.

i cant see any actual markings that its a Wiseco, im guessing due to the sticker on the tank that maybe they upgraded.

Its def not a stock suzuki piston as has no suzuki markings on inside (like my other orig on) but it does have TS185R on the inside of piston.

Piston appears in goodish nick, some blow by, not too much scoring, though it does have one mark where it appears to have maybe hit / scraped base of barrel at some point. The skirt has no cracks, although it does have a little flat spot on the four corners of the skirt, seems pretty uniform, not sure if from  manufacturing or from being in bike ?

im a noob to pistons, but compared to my other orig one this one appears to have a slightly smaller diameter but the rings seem designed to "flare" out heaps more than the stock rings on other piston.

so some questions

what do ppl think this piston is? any specific wiseco markings ?

does it seem in ok condition

is it true the rings flare out further / better than orig piston / ring setup, whats the benefit if so ?

cheers

Used a brake bleeder to suck heaps oil out, had a real good feel of crank, can wriggle left and right slightly, but no up and down movement at all, appears the main bearing might be in good condition.

Cheers, that another reason I wanted another parts bike as the little lever type part of the clutch mechanism at the engine on my orig motor seemed a bit so hopefully part on new bike is fine.

Thanks once again, will update with pics / more info in coming weeks

Hi matt, it seemed to be identical oil in consistency and smell.

In saying that to me it didn't seem like the two stoke oil I'm used to, could be due to sitting for ages or type of oil, it seemed more like engine oil.  I like your idea re. Which engine to use, donor bike does flick through gears ok.  I will take picks over next week or two as I take engine out and tip upside down / remove piston and really check out main bearing tolerance.

I will use my orig. engines side cases though as the donors bikes aren't in as good condition, the left side very outer flat cover must have been smashed at some point and is now made from a pop riveted piece of metal and sealant!, can sort of tell from pics above. Though from looking I can /will change the whole left side cover, not just the flat very outer cover also the main cover as donor bikes has/ will have pot rivet holes in it if I only replace the very outer cover.

I'm assuming from seeing them sold online etc that the outer covers ( clutch / fly wheel) are ok to interchange between bikes ? It's only the main cases that need to be a matching pair to ensure they seal perfect?

Thanks for all info and advice so far.

Hi All,

Need some advice from the experts.

The bike i bought above scored me a nice exhaust & kick start that i needed and then all the various spares so worth the small outlay.

Pulled the barrel off, barrel is nice and neat, one cracked fin.  The main crank bearing feels tight with no movement at all, though it is swimming in engine oil so there is a a gasket or seals gone somewhere.

I have decided i will take my time and rebuild an engine, questions is which one do i pick.

My orig one i know worked, all gears etc, its bottom end is gone (crank bearing) though no oil leak here, clean, just piston skirt debris inside.

Other engine the crank bearing feels very tight, though swimming in oil, does this straight away void the crank bearing making it useless ?

i know i have to use the same cases in regard to splitting them and putting back together, is the oil soaked crank / bearing / rod useable to transplant into my orig motor if one removed and cleaned of oil has zero movement ?

Any info / feedback would be appreciated as usual.

I also figured i would need a list of special type tools, i plan on playing with motorbikes and other motors all my life so dont mind outlaying for specific tools.

Already have a fly wheel puller i bought a while back

yesterday i have bought (ebay)

Kincrome Impact screwdrive
Kincrome sliding T handle 1/2" so can use my sockets easier
Flywheel / Clutch locking Pulley holder.

i then hopped on Rocky Mountain ATV, a US site and compiled the below list of items that im thinking of getting, postage all up is $50 , same as ordering one of these items via ebay (total incl items $204).  Main expensive items i figured i would need are the crankcase splitter and the bearing puller, grabbed other items as always handy to have on hand.

Does this sound like overkill "shop" tools wise or do most of you guys who do rebuilds own / have made these tools as it makes the whole job a hell of a lot easier and less chance of damaging things ?

quick update, havent been on for a while.

My daily "TS185" ebay search paid off, have been looking for a parts bike so as i have spares and the possibility of finding one with an OK bottom end.

Found this one today and quickly rang guy, scored for a low price.

even if motor shagged i score what looks to be a old bassani pipe ? and the kick starter and of course everything else as spares.

Quite happy at the moment

Bit of an update on Kawasaki.

Now lives out side under cover while play with Suzuki.

Today I reset the point gap to check all good, set at .34mm.

Also at the time I checked the fly wheel for any movement, there is no in out movement, no left right move,ent but there is a slight ...I mean very slight amount of up down movement.  I wedged my finger in behind the fly wheel to the back plate while doing the jiggle and that appears not to move, it appears to be though not sure if possible that just the fly wheel is moving slightly ?.  I checked the Suzuki as motor on bench, that has zero movement - nil, although that engine the big end bearing is gone.

I got myself a torque wrench today as sick of borrowing father in laws and also a fly wheel pulled for re,oving the Suzuki flywheel etc.  then went to buntings and grabbed a bit of flat steel so that I can make a bracket to check the torque on the Kawasaki fly wheel nut.  The nut feels tight but it may not be the correct torque and thus could move slightly?.

Checking on google etc, loose flywheel it says bottom end gone etc bike will be hard to start and left crank seal will be gone and will blow smoke severely....bike doesn't do that at all.

Also I was home I'm Mildura recently so dad gave me a nice old c clamp and a huge 5" ish bench vice "Dawn" brand, heavy sucker weighs 25kg.  Will clean it up and most prob just keep to install in my next garage in years to come.

sorry if a stupid question but when you say buy the second hand bottom end, you mean buy another motor just missing barrel and piston etc, or still crack my cases use my motor but buy second hand when i get the bottom end etc ?

cheers

Yeah 185 frame are fairly tiny.

Still deciding what to do so far advice is.

Fix it, shouldnt cost you too much
Stripping the motor you have already got will cost you nothing, only 'specialist' tool you will need is a flywheel puller $25 and even then there are ways around it or im sure someone here can knock it off for you.
You can see what needs replacing and unless its something major like a complete crankshaft then it is going to be cheap.
Rod kit is less than $50 with top/bottom bearings
Gasket set ~$50
Piston kit ~$80
Shop to press your crank $65
Rebore $65

Next option ppl say is buy another motor and just do top end rebuild as generally the TS185 sierra model motors bottom end is bullet proof.

Other ppl then say buying a second hand motor is just a side step unless seen it running in prior.

What are ppls thoughts............im guessing my engine is at the end where it needs a fair bit done as opposed to getting a second hand one cheap and just doing piston rings etc.


remembering i have never split cases on a motor before, have just the standard garage tools and want to limit outsource costs to a minimum.

weekend rider, on rec reg is all i want, so may be best to source another motor, ill keep my eyes and ears out for another motor whilst doing all the simple body work and treat this one as a spares.  As you mentioned i would rather not have to outlay much if any cash to someone else to do the work.  If i get another motor only real outlay is barrel bore etc.

Cheers

Cheers doc, I'm in no real rush (only 28 ).

The bike doesn't have as much sentimental value as Kawasaki but still want it rebuilt, I want a good decent old bike setup for vinduros, I think this could be it and if all engine work done it would be like new, I could buy another second hand ts for the $400 price but odds are it would need something done too.

If I rebuild this engine do all the stuff I want to still a cheap vinduros bike and I should feel confident to thrash it around.....sound realistic ?


Also managed to get the pin out which I was happy about.

Top end bearing its called yeah, seemed ok, though you replace it anyway.
  Definite movement up n down in rod see vid below.

Ok bit of an update.


I think I exaggerated re up down movement, though there is def some movement maybe 1-2 mm which I'm guessing would mean the needle bearing which I think you call the main bearing is prob worn out or broken.


Measured the piston 63.8 mm


Measured Barrel 63.9 mm


That's with my vernier calipers, digital not most expensive ones but atleast let's me know nothing has ever been done before.  Piston just has the front arrow on it same as Kawasaki did, 100% sure orig piston.


Barrel looks ok like I said earlier, does appear to,have some slight scratches that you can just feel at base of barrel.  No real nicks or lips at all around ports that I can see.


I also smoothed out the head a little, just concerned about 2 deeper holes, should they be filled with weld or something ? Or be ok , or buy new head


Let me know what you think, cheers
