Will it still run???

Deltascoutsniper · 02-17-2008, 04:39 PM

I just bought a 1999 Honda XR200R and you couldnt roll it off to start and the kick start wouldnt budge i tore down the motor to find the intake valve had broken of and punched a good size hole it the piston ive gotten all the dabre out of the motor and need to know if i put in a brand new piston and intake valve it itll still run once i put it all back together or if it would be just a waste of time and money

Deltascoutsniper · 02-17-2008, 06:51 PM

everything in the motor looks fine just a little wear in the cylinder nothing that honing wouldnt fix the only damage was the broken valve and piston

your pretty lucky then

change the fluids while your at it in case there are any tiny shards in the oil/ antifreeze

Deltascoutsniper · 02-17-2008, 07:40 PM

yeah i def already changed that the oil looked close to liquid metal not to metion the peice of piston about as big around and about half the length of a cigarette butt just one more question though being the first time ive done anything with the top end of a motor what percausions should i take getting the timeing chain and the camshaft back in when i get it all back together

Ok, some things to make sure you do. Make sure that you change the oil at least 3 times on the first ride. This may sound expensive but to get things running solid again it is necessary. Make sure to change the oil filter each time as well. Next, make sure that the valve guide is ok. Check this by inserting a new valve in the guide and seeing if you can rock it back and forth. Also, you will want to check the valve seat to see if you need to get it recut or not. Make sure to hone as everyone has said as well. Why did this valve brake off? Most likely due to wear. So which one is next? You should really replace all the valves and the timing chain as well. Good luck.
