hey guys,
it seems as soon as i fix one problem another one pops up. Now that my carbs are spot on, i have another problem. Well apparently i was leaking oil the whole 42 mile trail ride and as soon as i get into town the engine shuts off (without knowing while im going 40-50 mph). while holding the clutch in i shift into 2nd let go of the clutch and i hear grinding. i know its not the clutch cuz i just put a new one in there and it was fine the whole ride. I checked the oil and there was not 1 drop in the tank. no the engine is not seazed, it will crank over. so my question is, does the 03 raptor have a low oil shutoff?
thanks guys

The only low oil shut off it has is when it locks up.

Running low or out of oil will cause heat. Parts grow / expand. Damage done. Engine cools down and the parts contract alowing the engine to turn over.

No. Only thing that stops the engine due to lack of oil is damage.

Atleast pull the rocker box off the top of the head to check the cam out. As willykiller said the cam and head will suffer damage first. So if it is damaged anywhere it will be there.

Remove the cam and check the cam journals at the head surface, they have the most load on them, also look at the rocker arm pads and cam lobes, these need critical lubrication since they are all friction surfaces, the rest of the engine is bearings and can survive for a short time without proper lubrication except the piston, it needs splash lubrication at all times................

If you're an expert, a few minutes... if you're a rookie, a few hours. You decide.

im not a rookie, but no mechanic. you think i can wait, put the new gasket on, and see if it runs first, or will it damage more, and cost me more time and money.??

Yea the top cover is just Yamabond 4. Use that and not the the RTV or Ultra sealers from the parts store.

Would be best to know exactly how bad it got, and what all has been damaged. The cost of repair could be as low as a few hundred dollars if you don't have much wrong, can do all the work yourself, and find good deals on used parts. Or you could be at the point where you're better off taking the engine to a scrap yard than rebuilding it.

There is absolutely NO way we can tell you how much work is involved nor how much it will cost.

Next time, if you watch your oil more carefully, it will cost a whole lot less to keep running.

Sorry, not trying to be flip with your current problems, but you are asking questions that do not have answers except to avoid the problems in the first place.

I have dismantled and reassembled raptor engines several times in the past, including my own. Going from my own experience, I would get someone with a lot of experience on raptors to do the job for you if you do not feel qualified.
I can completely take an engine apart and put it back together in a few hours, but if there are repairs to be made, this all adds to the cost, such as changing bearings, boring and hone finishing, valve job, etc..........
