Flushing gsxr engine?
Right people, the self destruction of my gsxr engine balance shaft has left my internals covered in tiny metal particles. I have removed the old
balance shaft and replaced with a dummy one and cleaned as much of the particles out as I can but what's the best way to flush the rest? Do I
fill it run it and change it several times and if so is there a cheap oil I can use? Cheers sam

What about a magnetic sump plug or putting a strong magnet on/in the sump to try and collect the swawf. When i used to work on trucks their sump
plugs were usually magnetic. It's amazing tthe amout of bits they used to collect even on a good engine.

not sure which engine you have but wemoto.com or
ebay sell them for not much money. I
wouldn't be surprised if the same plug fit most models.

Perfect planning prevents pi$$ poor performance!

Not wishing to sound pessimistic but....
If you have been running with metal particles in your engine I don't hold much faith in the engine lasting very long.
Bike engines are made to fine tolerances and it does not take much for them to run the bearings and throw a rod.
There is bound to be oil pump and bearing damage.
At the very least you should inspect the oil pump and main bearings and possibly a full strip.
A hillclimber had a clutch basket explode a couple of weeks ago.
He cleaned out visible metal but next time out he ran a bearing and put a rod out of the block.

Cheers guys magnetic sump bolt it is with several drains and flush. Minitici I have stripped the whole bottom end of the engine to get to the balance
shaft which sits in front of the crankshaft. The big end bearings, gearbox and oil pump all seem fine so fingers crossed may have cought it in time.
Only time will tell I guess.
Cheers sam

Everyone will tell you that it will need a complete strip down and if this were a helicopter or ambulance (failure is not an option) then that is what
you would do.
In my practical experience, the cost of a complete strip-down and rebuild is quite a lot (in gaskets and such), and unless you are good at this sort
of thing there is a fair chance that you will break something or put it back the wrong way around or not use the right thread-lock, or whatever.
So, I am a fan of flush and hope.
Regarding the oil system it goes:
Sump-->strainer--> oil pump -->cooler --> filter -->engine
So if it makes pressure, then the oil pump is fine (although its easy to check if you have the engine open), and then you are hoping that the filter
has done its job.
Cheap oil is probably the best because you are going to dump it and not going to rev hard, but worth buying a couple of oil filters. If the engine
makes new strange noises or isn't 100% happy then you can always do a strip-down before you knacker the crank/rods/cases.
Good luck!

Flush
Not sure if any help, but i raced 250cc long circuit karts for 10+ years
Tuned two strokes being what they are we encountered similar partical issues, mainly when the clutch basket tended to let rip. We soon learnt that
billet baskets were the way to go !
Anyway, if a full strip was not practical (midnight oil in the pit garage etc) we always flushed with petrol then ATF (automatic transmission fluid),
never had any ill effects.
Yes of course its different to a 4 stroke but just offering my two penneth.
