OEM gaskets ain't particularly cheap. Patten ones are.!

Are they OK or more trouble than they are worth and the higher cost of the OEM ones is soon out weighed by less hassle.?


Cheers, Nick.

Only ever used pattern gaskets, never been a problem.

Pretty stupid idea tbh unless you know what you're doing.

For somebody asking about an air filter that can't rejet a carb, you're hardly in a position to recommend changing compression ratio

Used pattern on a full RS125 rebuild. You'd need to check with G as to whether they are lasting but they were fairly decent. I'm using a nowhere.elysium pattern gasket made from a Budweiser box which hasn't leaked yet Laughing its a year old too

Cheers for the posts so far folk.

Its not a high pressure point (in this case) Its just the clutch cover housing.

So it seems that Pattern gaskets are fine, hunky-dory & spiffingly-dandy for this. Wink


Cheers, Nick

What do you have against me? You dont even know how much i know about engines, ect. Just because i dont know how to rejet a carb, that has nothing to do with changing head gaskets. It wasnt my idea, it was a trick i was taught by a moto-maniac. Carbs and air filters are much more difficult and delicate to deal with, if you get it off balance by a little bit, it'll change how the engine runs and can possibly ruin it.

Anyway, surely by making the head gasket thinner by like .1/.2 of a mm, it isn't going to make a heck of a lot of difference to how the engine runs.

Yeah i was taught that also, but in my motor class so many people are getting it wrong and it can ruin the engine if you hit it too hard. My method (or so i was taught) is a bit more safe. Wink

I think the point that Paddy was making was :-

If you don't understand why changing compression ratio will affect how the engine runs then you shouldn't be doing it.

By making the volume smaller the expanded gasses need more room to escape. This will make it more powerful but not by much... I do understand, but its not going to make a great difference.

unless of course someone has already skimmed the head / used a thinner gasket. then you end up with the piston making sweet sweet love to your valves.........

i can see where you're coming from, i'm just not sure where you're going to end up if you keep coming out with very short sighted ideas like you have been so far. trying something different is all well and good, but giving out advice to others who may think you know what you're talking about could have catastrophic effects on someone elses pride and joy.

if you're not 100% certain about the advice you're about to give, don't give any

If you up the compression too much then the mixture in the combustion chamber will spontaneously combust rather than burning, and this violent explosion can easily cause very large amounts of damage. Hole burnt in the piston being the most likely damage, but knocking out the big end bearing is also a distinct possibility.

All the best
