stevem099 Posted March 19, 2014 Report Share Posted March 19, 2014 Hi all. Well I've finally finished rebuilding engine started after a few kicks much to my delight However it was leaking coolant from the base of the barrel.. Removed barrel and I believe I've found the issue just wanted to make sure. On head gasket should the silicon pattern and writeing face upwards? I believe I've fitted mine upside down lol Many thanks Steve Quote Link to comment Share on other sites More sharing options...
feetupfun Posted March 19, 2014 Report Share Posted March 19, 2014 pretty confusing post there Steve. Head gasket goes at the top of the barrel not the base of the barrel. Or maybe you are talking about problems with both the head and base gaskets? Quote Link to comment Share on other sites More sharing options...
stevem099 Posted March 19, 2014 Author Report Share Posted March 19, 2014 My apologies. I meant the base gasket. The head gaskets (o-rings) seem fine. Still learning all the terminology on these 2strokes haha Many thanks Steve Quote Link to comment Share on other sites More sharing options...
milkybarkidtech Posted March 20, 2014 Report Share Posted March 20, 2014 Hi Steve. The techno base gasket is obselete to buy as a part. what colour is your base gasket as the green base gasket with blue piping on is for rev 3 onwards. There are two options you can go down to get a techno base gasket. 1 is to buy a full engine gasket kit from beta-uk and 2 is to buy some gasket paper and make a new one. If the base gasket hasnt been replaced it could have a slight tear. Quote Link to comment Share on other sites More sharing options...
stevem099 Posted March 20, 2014 Author Report Share Posted March 20, 2014 Ah this maybe why it leaked. I recently rebuilt engine with all new gaskets but the one I fitted was green with blue seals. I've ordered a new one online where it stated it would fit techno rev and evo 125-290cc I shall see how this measures up if not I'll try making my own. Thanks for your help. When normally fitting the ones with blue pipeing would you have that facing up towards the barrel? Cheers Steve Quote Link to comment Share on other sites More sharing options...

stevem099 Posted March 20, 2014 Author Report Share Posted March 20, 2014 How do you know Quote Link to comment Share on other sites More sharing options...
stevem099 Posted March 20, 2014 Author Report Share Posted March 20, 2014 I've just compared them you are 100% correct they are indeed different! What a pain in the backside lol. I'm not buying another gasket set :-/ think if get away with a cut and shut of the two with a small bit of gasket sealant? Quote Link to comment Share on other sites More sharing options...
petert Posted March 21, 2014 Report Share Posted March 21, 2014 post a pic of the one you need, as I have a brand new unused base gasket that is of no use to me! Quote Link to comment Share on other sites More sharing options...
stevem099 Posted March 21, 2014 Author Report Share Posted March 21, 2014 Ok brilliant I'll post one tonight when I finish work. this is my first trial bike, brought it as a wreck thinking it would be a cheap way to try the sport lol. In hindsight I wish I'd brought something newer as so many parts seem obsolete on the techno I've spent ages sourcing parts lol Many thanks steve Quote Link to comment Share on other sites More sharing options...
