Replacing piston and ring

mc46 · Apr 25, 2013

Now that I know I got a oil burning issue, does anyone here knows how much will cost me? Do I just replace the piston and ring or i need to robots it and replace with a larger or next to standard size of piston and ring? Though my bike still run well, I need to prepare ahead of time, I should say I need to top up my oil 1/4 for a 1k kms. No smoke on idling, but when you rev it there is visible smoke, but not much. Did a 8k kms with the new plugs but still alive. Need your opinion. The worst is no good mechanic here to do it.

I would ride it utill i starts burning bad. Like 1 liter on 500 miles.
Then i will start preparing for rebuild the engine.

How many miles/kilometers you put on your bike in one year?

I have 30k kms.

Have a respected engine builder familiar with the issue like Lee's cycle do a Supersport rebuild. You will spend far less than you think and have a bit more power to boot!

+1 My '08 has a supersport build w/JE pistons and some headwork. It runs far better than before! :thumbsup:

A leak down test is more accurate. :thumbsup:

It may not be the rings that are bad. It could be the valves. I would do a compression test and see what she is like. Should have 155-160 psi all across the board. A difference of 10% between 2 cylinders could mean engine rebuild time. Keep in mind a lot of the 08 1krr had oil burning issues.

If anything other than the normal bad rings it would be the valve seals not the valve unless a valve stem is bent. In which case the motor wouldn't run (or run like shit) OP is only burning oil, runs fine.

To OP: Valves probably need adj.

Thanks. So you mean the steam or valves?

I can also hear a noise in valve when idle.

Check the valve clearance.

Get it to a dealer, the oil burning issue is known and covered by Honda for 5 yrs. from original purchase.
