quick up date folks, after the clean out i still heard a noise so i had the engine stripped down and it was found the main bearings were the cause of the noise. Had it re-built with new mains, little end and a gasket set and its all good now. thanks for the help through out my problem.
just a quick update, i could'nt help my self i took the carb off and found 2 flakes of aluminium in the bowel " how the hell did that get there" also removed the tap from the tank and sure enough there is dirt around the bottom of the pipe, iv ordered a new plug although this one look good just to be safe. Its strange that this could cause the knocking noise, i guess i have a lot more to learn about 2 strokes. I look forward to getting it back together to see if the noise has gone.
Should i turn it up side down and clear the crank case out as well??
sounds like good advice, i had a problem with dirt in the carb last week so i cleaned it out along with an oil change and new plug and air filter, i guess i should have cleaned the tank as well, ill report back my findings during the week when i have a chance to take a look.
cheers
just a thought over night, i have a new in-line filter fitted, surely this would of stopped any dirt from the tank???
Try a new plug, then see if the noise is still there.
thanks for the reply, can you say why a plug would make a difference so i understand why i am doing some thing, it was a new plug at the start of the day?
Hi, Don't panic yet. you have probably taken some dirt into the carb as fuel was running out. give carb a clean and flush out fuel tank and it will be fine........
Check the fuel flow from tap too to make sure top is not blocked in the reserve outlet.
lean mixture will make it KNOCK !

hi Folks, i think my engine is broke, i ran out of fuel so went to reserve and after re-starting it never sounded quite right, when accelerating and backing off there is a knocking noise which sounds like its coming from the bottom of the engine but could be any where. It feels like i'm down on power and the power is also not as smooth. any suggestion what i should look for, i always think the worse so hopefully one of you guys can point me in the right direction.
Just spoke to my dad. Clice do the bigger sizes but only available in black and grey. My pops is a 38 waist and bought the xxxxl (42) but says the xxxl (40) would have probably been better for him. Hope that helps.
Hi everyone, thanks for your comments, some of them i have already looked at. I spoke to a supplier in the UK and they have told me many of the importers don't bring sizes over 38" into the UK. Clice go up to 44" but UK importers don't stock them (factory order only) Jitsie go up to 40" Wolfsport up to 38" in trials pant but 46" in enduro trousers but they have said they can get some trials pant made in 42".
This go me thinking is there enough riders out there that would like the correct branded gear????? if so i might open discussion with the factories/importers and bring gear in for the larger rider.
Hi Folks, i'm new to riding and just getting kitted up but i can't find trousers/pants in my size, most companies finish there sizing at 38" i have found one company going to 40" waist, i would like a 42". i am sure i am not the largest person to ride a trials bike, i know the wife says i should my be seen in Lycra but never the less i would like the right gear. Any advise of where to shop in the UK or online for world wide shopping?
PS. I think some one needs to tell Hebo XXL is not 38" waist
