Engine work for sumo

This is what happens when you have unwanted water sitting in ur engine for 4 months.





Already replaced the aftermarket piston and rings along with teh cam chain and teh water fubared the cam chain. Problem started when i realized i had a bad head gasket. Well after the gaskets, piston, rings, cam chain, carb clean,removed valves and cleaned, shimmed, new plug the bike would not start. I just got an email from my engine guy this morning that said this

" Bad news, unable to start YZ. Re-checked valve clearance, spark among other things. I only get a rare pop when trying to start. Tried to do a compression check but this motor has an automatic decompression system. With auto on I get 20 psi with it off I get 90psi. Generally you need 100 psi to run and this would be low performance. Unfortunately this is not that great of a test since the rings are not broke in and valves may seal better after running. Also did a leak down test which shows moderate leakage. I attached a pic showing that the valves where rusted in head and needed to be driven out due to water ingestion in combustion chamber. Also adding salt to the wound is that just from kicking coolant is leaking from the base gasket area and water pump mechanical seal. This might seal up once the engine runs.

At this point unfortunately I would recommend taking engine apart again, install new valves, new guide seals, getting a valve job on head, replacing 2 seals and gasket for water pump leak. Seals and gaskets around $70, Valves will have to check but if Titanium around $100 a piece x5 plus head work around $300. I have not checked prices in awhile so these may be off. This is not the best situation due to the fact that this head has suffered damage from water scoring cam bearing surfaces and possibly warpage to head surface."


I hate when shit like this happens. Ugh. At least its before the season starts and I have time to get it fixed and pay for it.



So the question I have is after bringing in my bike for this work to be done what is the going rate for work like this do be done. Granted these are not stock parts since it needs aftermarket piston rings and gaskets. With all this work done is this considered a full rebuild? LOL

See what his total estimate comes to and see if it's fair. I would rather go with a new rebuild than a used head though.

No I did not talk to Tom yet. I have a tech who is a mechanic and racer working on my stuff right now. With parts and labor I am into it for $600. But I am guessing with the new valves and stuff it is going to push me over the $1000 mark.

your looking at around $350 for oem valves. Look for a used or like new head on flea bay.

With all the rust on the top end I would be concerned with the bearings in the bottom end. Ask Gus about Jack's 250F. I think every bearing in that motor was junk.

So are you suggesting I replace all the bearings in the bottom end. What about the crank?

I would if I didn't have $3000 in engine work done to it. If worst comes to worst I will toss my stock 08 engine in. I am waiting to hear back from my mechanic to see what he says.

You should check all the bearings , IIRC , they had oiling issues . How can it cost 3k for a motor ? That has to be with some very trick parts.
