ok ,heres the deal ,,,i have a 99 sh ,it was just sitting at idle warming up and then made a little noise ,then made a bigger NOISE ,then just quit ,,,pretty sure it's the cct's ,,it's got 27k on it ,should i be worried about bent valves ,is it a tolerance motor or what ,i have not tried to restart it cause i know somethin' is wrong in there , it make a nasty ,loud clapping slapping sound just trying to bump it a little...........................
Thanks in advance

 

yes it is an interference motor.
guess you should have replaced the CCT's

 

if you think its the CCTs, then yes you most likely will have bent valves. Not a better way to check then to take the valve covers off - the timing marks on the cams will no longer be aligned front to rear cam, and the clearance on the bent valves will be much much wider. If so, once you take the head off you can assess the piston. If its just a couple of valves you can have them replaced or used heads are not uncommon but hard to know what you are getting that way. Its likely just one cylinder.

sounds bad, sorry. if you are handy mechanically you can do most of the work and just pay for the technical things (valve replacement) if you aren't familiar with that part.

 

If it sounded like a can of spray paint rattling, yea, you bent the exhaust valves.
As stated above, pull the valve covers and check the cam timing marks. If out of proper alignment, yes you will need to pull the head off. Don't worry it's not as bad as you think. You should replace all four valves and have new seats cut. If you do most of the labor yourself it won't be that much. But if you pay the shop @ 75per hour, ouch!

Find a reputable mechanic that can re-cut(clean up) your valve seats and install the valves on the head. @ $100-125

Read the manual and follow the directions. Yes, you should remove the rear valve cover too. So you can check proper valve timing.

 

thank alot guys thats really not as bad as i thought ,but i'm still bummed ,i've only had the bike 6 mos. but what fun it's been ,i'll let you know how it goes ,thanks for the price list thats saves time....

congrats.

 

Where did you buy your parts? did you do the work yourself?

 

Glad you got 'er back on the road.

 

Whats the o-ring for that motojoe suggests in his rebuild parts list above?

 

^^^I would be suprised if no one has an answer to this. Anyone...

 

I don't know since I haven't removed a head, but my guess is somewhere between the head and the cylinder sleeve. lol

 

likely an o-ring for the spark plug well. I haven't pulled a head off of a hawk yet but it's not uncommon to have an o-ring around the plug well either where the top halve of the head (cam carrier) bolts to the bottom or where the valve cover bolt to the head, depending on the head configuration.

 

I don't remember exactly, but I'm pretty sure the O-ring thats suggested is the one on the dowl-pin when you remove the valve cover. It's been a while since I did the job....

 

I think it's the PAIR tube that has an O ring.

 

and we have a winner.......
