Craptor was making a rattling noise...

[loganskinner]

to start the story, my buddy, 660_rider03 put his 660 raptor engine in the shop about 2 months ago, to have it serviced, a new timing chain put in and some valve work done.

 

well he finally got the engine back two days ago, and put it in yesterday. he called me to help him, but i was busy so he started by himself. i got done with my work and headed over to help him out. i was late and he already had the motor in place and mounted. we hooked up the battery, and the pipe and he started it up. it idled nicely for about 2 minutes, then started making a wierd clanking/rattling noise, and then shut off. he tried to start it again and the starter wouldnt turn over the engine, it sounded like it was catching on something. well a few more pops of the starter, and it fired right back up. it idled for another minute or so and then came the rattling again. i said "man did you put enough oil in it?" "yea man, its fine. i checked it when it shut off and its all good." the rattling got worse and all of a sudden BOOM!POP!CLANK. the whole side of the valve cover blew off and 2 small screws shot out at light speed, and hit me on either side of the boys. i fell to the ground screaming bloody murder, and saying something about suing the Yamaha Corporation for the loss of my penis.

 

but thats not the point, the screws came form inside the engine, they shot out from the inside of the top of the valve cover. ill try to get a pic, but do any of you 4 stroke guys have any idea what the bolts came from? they are esactly the same size as the ones that hold the rear plastics on the frame of the shee.

If it were me...I'd put that motor in the back of my truck, take it back to the place that did the work on it, toss it threw the front window, and ask then nicely to get it right.....

you forgot the part where you kick the mechanic in the crotch

Man did you ever get screwed...

 

Seriously, I second Otto's motion. I would expect the mechanic or engine (re)builder to acuse you of wrong doing that caused the engine to detonate. It's the American way.

 

What does a Raptor engine or the necessary repairs cost these days?

All my friends that have raptors, always have have some problem with it, and they were the ones giving me shit for getting a banshee, because of how unreliable they are. pffft, I'm the only one who can go riding at any given time, because my quad RUNS. No problems yet...knock on wood

 

Loganskinner, it sounds to me, like something was too tight, and as the engine warmed, got even tighter, or something was floating around loose in there and got caught up in the timing chain or something.

[loganskinner]

yea i catch hell from all my buddies. they all love thier 4 strokes, but ALL 4 of them are having problems right now. marc's Z400 needs the valves adjusted, Aarons Craptor blew up, Brians Craptor wont start, and Louie's 450R is just slow.

 

im glad ive got my shee. shit i always end up riding alone.

you hit it on the head. on the raptors (most likely all 4 strokes) not everything is susposed to be tightened up in the engine, they have like certain tightening specifications for everything. Thats why I dont like 4 strokes, they require more engine maintenance. on a banshee, probly just check the compression, change the spark plugs, change the oil, and grease stuff up. on 4 strokes, you gotta do valve adjustments and all this other crap.

I had a friend who told me "you only need to adjust your valves like once every 5 years man" Like a week later he threw a valve into his piston and screwed himself out of a ride. lol

 

Banshees are reliable if you take care of them.
