2 head gaskets in two weeks
-
@Calum yes I know striped the threads don't know if they were doggy to start with so re tapped to next size up and now I know they good just thought I would mention incase it meant something
-
@britshgigolo Yeah well there is going to be massive pressure there bud, you will be massively down on power as well!
This would have nothing to do with the head gasket though mate. This has to do with the fact two strokes are designed to create a pressure wave to lost fuel and air back into the combustion chamber.

Mick did my cylinder and head the other week and didn't skim any of the faces he ported it and did the squish but am guessing he didn't feel the need to skim them I cleaned them up torqued it down with genuine gaskets and tbf the bike hasn't missed a beat but then there was nothing wrong with it before I stripped it for Mick and the bikes done less than 5000 miles
-
yer when he did mine he skimmed the head heavly to get it right and told me to use two spark plug washers/gaskets to be on the safe side to stop the piston hitting the head wish i had sent the cylinder to him now but the idea was to get it done quick as was a spare top end so i could send my original off to him for him to play with and work some magic on but as have had problems im still waiting to get it running right before i send it off have ordered a new gasket and will skim both head and cylinder again and see what the out come is as no rush as have put the original back in for now as use for work eveyday
-
@britshgigolo I had mine back within a week bud definitely worth having down it responds better on the throttle at whatever rpm where as it really felt lazy before
-
thanks for the info and yer will be getting it done as soon as the other runs fine there no point with the spare as its on max limit now so will be getting it resleaved then will send that off to as always good to keep spare on the shelf as never know
-
Well think I found the problem the piston was catching the head gasket it has been bored to its limit so should of checked really but hope now it will be all ok give the bore and head a light skim to make sure it had not warped but all seems ok so fingers crossed this time will go ok when I get time to put it back in
-
i had already done the power valve before and that had no signs of problems when i took it apart just the head gasket and its where you can see it has blown across from the cylinder to the water jacket so hopfully this time it will all be ok
-
@britshgigolo You may find a copper head gasket will be your ticket, if modifying the gasket proves too difficult.
I believe you still need sealant on copper gaskets, although don't quote me on that.
Just be wary of the powervalve is all.
-
was told to use this with copper gasket Permatex Copper Spray-A-Gasket Hi-Temp Sealant they said give the gasket two coats before fitting my self i dont know anybody that has used one personly so can only try
-
yes i know that was talking about the copper head gasket
-
@britshgigolo ah okay, thought I'de been doing it wrong this whole time for a second there!
