I reckon i have sorted the problem out now, Don't think it woz a piston ring(Still cud be, haven't hadf a test yet). But someone told me that i cud have too much oil in it so i checked the dipstick and it was way over the max. So i changed the oil and put the right amount in. And now all is well, i went on the motorway, and i have fixed my 5th gear now aswell so all wwent well on the motorway. I'm gonna go to Doncaster this weekend so that will test it out anyway. I will take my toolbox with me just in caselmao I will still take it for a tune up. It smells as if its running a bit rich with the petrol, so i will get a garage to check that to.
wot do u reckon about a filter for my engine, shud i get a K&N filter to go on the carb, or just get a replacement filter for the standard filter box on the engine. Or shud i get some other make of filter. Not really that bothered about the noise of the filter as u wudn't be able to hear it anyway coz of the exhaust
