The old saying "Anything is fixable if you throw enough money at it". You really need to take the head and cylinders off. Usually a broken timing belt causes the valves and pistons to meet (Not good) and results in bent valves and damaged cams, the piston usually suffers as well, but it can also bend the conrod. If the conrod is damaged you are getting to the point of no return. If it's just the piston and valve gear and you can do the mechanical work then it's very savable!! You won't know until you remove the barrel and heads and see the conrod!! What sort of RPM was the engine doing when the bang occurred? The lower the revs the less the damage..

If you can do the mechanics, then you are looking at $200 for a gasket set (you might get it down to $100 if you can just buy the head and base gaskets for the damaged side, rather than a complete gasket set), $80 for piston and rings (assuming no rebore required, ie. damaged piston did not score barrels), $100 for new valves and machine work to fix damaged seat/guide, then $50 for oil and coolant. You still need to buy 2 new timing belts and I would change the oil filter, so I would estimate a minimum of $500 assuming the con rod was not damaged and a couple of full days of your time to dismantle and rebuild the engine.

Your best and cheapest solution (if you want to keep the bike) is to get another engine. They can be had for as little as $200 or $300. But if you want to go the easiest route then sell it and get another bike. Been there done that. I elected to repair but I only had valve damage.

I would like to keep the bike but don't have a ton of money to throw at it if I could get a new engine for around 200 I'd look into that otherwise how much is my bike worth the way it sits ?

Depends on the overall condition but a few hundred at best if the engine is toast,

I'm gonna try to bring this engine back to life I have a gasket set came with the bike when I got it found a set of 4 piston with rings n rods for the$50 and the valves are relatively cheap is there any other parts that may be broken aswell or should that pretty much cover it ?

I am not 100% familiar with the 1200 engine, but the only other thing I can think of is the rocker arms. Usually the valves are not driven directly from the camshaft, there is a rocker arm between the valve and the camshaft, this arm might have got twisted or damaged, so you need to check it very carefully (Just compare it with the other rockers arms to see if its bent). I really can't think of anything else that would have been damaged.

How are the cams and the connecting rods?

Have you even looked at those yet?

What kind of gasket set is it.

If the head gaskets are not OEM, you are wasting your time.

The cams look ok and the pistons I'm looking at come with the rods as for the gasket set I'm not sure it came with the bike how can I tell if it's the correct oem replacement ?

The guy I got it from said it was a full gasket set for the bike but then again he also told me he just changed the timing belts which he obviously didn't or did but incorrectly

There should be some kind of numbers on the packaging or is it all loose?

Seriously tho, if it's not a Honda set, you can probably count on redoing the head gasket with a 1000 miles or so.

There are just somethings you don't cheap out on.

No offense but you tend to have a habit of not answering or giving us the info we ask of you.

We are trying to help you but it's like pulling teeth.

I thought I did answer the questions except the number on the gasket set which I don't have access to at the moment as I am at work I'll check it out as soon as I can
