Checks for refitting a engine

Apart from the actual putting the engine back togther is there any maintance that should be done. The "new" engine has been stored for an unspecifed amount of time but all the oil looks good pretty clean as is the coolent, however the engine will have been bounced, covered in with oil because it wasnt properly drained before carridge.

I was going to flush the coolent system to get any unwanted oil, i have already checked the valve clearances and obviouly will refill it with coolent and oil. A little bit of water got in the front cylinder about a tea spoon i reckon, there nothing i can do about it but will it have caused any damage? It only happend yesterday.

Is it a matter of bunging everything back togther and going for a spin or do the throttle valve need syncing etc - (bear in mind the engine and throttle body are from two separte engines). There seems to be a host of acronyms that can be checked, with loads of funny numbered gauges that i bet are riddiclouly expensive. Basically i am feed up of looking at the bike and want to get riding again but not at the expensive be back to looking at it agian.

Many thanks

Have you tried turning the engine from the crank bolt? That'd be a good start, make sure it's all free and moving before you fit it...

Indeed, check it rotates, do a compression test (if you have the kit) or just remove the plugs and "feel" for compression, manually check it engages each gear, check all bolts are tight,visably check for impact damage,when the starter is fitted make sure it spins the engine,Check the timing is correct,after fitting the carbs/throttle bodies you will need to balance them, once completly installed run the engine up for a few minutes, then turn it off and let it settle for 10 minutes, if you're not going to change all the oil at least drain 500ml or so and check it's condition (contaminats/debris) and top up if all is OK.

Cheers Mark.

Have checked that the enigine turns everything fine, realised the water was probaly in the cylinder longer than a day because it was a rusty colour however the cyclinders not making any horrible noises. just going to run it to see what happens.

will fill and change the oil as well

cheers for the relpies

Cast iron bores on an SV... If the water's carrying rust then there's a pretty decent chance that the bore's ****ed tbh. Not definate though. If it was me I'd get the head off and have a gander, if the bore's significantly rusted then you'd not really want to run it.

(should have said why), because as the rings pass over the rusted surface, not only will they get abraded but they could end up scraping debris off on the downstrole, into the crankcases. Not good news that, obviously.

Cheers for the relpies norty and rictus, I think i am going to send the engine back as it was sold as a "good" engine and i paid decent money for it. If i wanted to buy half an enigne i would have, sorry rant over.

The breaker in question will have been used by many on this forum before and depending on there response they will get named and shamed, the engine leaked oil in transit, was basically a rubbish job, there carrier is mighty unamused as well becasue it destroyed a whole load of other packages.

There wasn't any rust floating in the cylinder but it was a rusty brown. Listing to the engine more carefully i can hear a scraching coming from the front cyclinder, Grrrrrrrrrrrrrrrrrrrr.

Hmm... Yep, I'd be tempted to do the same, though I'd probably have the head off first and have a peek. Assuming it is knackered- because it might not be- you could put it right for not a lot of money, if you have a piston and barrel off your old motor, but you're spot on, you shouldn't have to with an engine sold as good.

They have agreed to swap the motor for another on there shelf, things are looking good at the moment.

I have got the spare parts to make it work as well, just dont really want to take another motor to pieces

Right diffrent engine has arrived which looks in better condtion (front cylinder head cover was split but everthing turns, goes into gear etc so i have put it in the bike.

Really hope whoever was riding the bike it ok, i guess to split the front cylinder head cover the bike must have had a massive accident.

Really stupid question but i take it balancing the throllte bodies are what the suzuki manual refer to as throttle valve synchronization and it is done with one of those ball in a tube gauges?

Has anyone ever had to adjust the STV,STP, or TP sensor when refitting.

My garage is relativly dusty when running without the airbox is the small possibley of fine dust getting inside very bad, obvoiuly no dirt of proper dust must get in?


Thankyou, really looking forward to get hearing a v-twin running again.
