Hi, as above, can you replace the rubbers on the bolts for the rocker cover with instant gasket?
If it makes any difference its a v-twin 125cc.
thanks, Grant

No. If any of it gets into the oil, it'll block an oilway and kill the bike.

If money is a real object, you could probably put an appropriate size dowty washer (sometimes called a bonded seal washer) under the bolt heads.

Check the price of proper rubbers though, you sometimes get a surprise.

If it was, say, a varadero 125, the cylinder head cover retaining bolt rubber seal (part number: 90542MB0000) sell at £1.80 each.

Any possibility you could get one out and measure it? Would cost pennies for someone to turn a couple out for you.

Put a piccy up of what they look like. There is every possability they are a standard part or could be replaced by one.
