well this was a worry! note where the circle is there's a bit of aluminium that's broken away from one of the two "fins" on the air intake side of the carb, I cant see it being a huge issue with the metal not being there but the obvious worry is where's it gone! im sure the bike would of gone BANG if it had worked its way into the cylinder, thing is it could of been like this for years and not been a problem or come off when off the bike at some point. tomorrow I think I will pull the reads out and check into the motor from that side obviously I know its not in the cylinder at the moment as ive just done the top end but I think if its not in the reeds etc I will probably pull the head off just to check!
after that Ive taken the carb to pieces and cleaned thoroughly, it would be ready to go back on other than having to search for the mystery bit of aluminium!
anyway here it is all cleaned up, The old drain hoses looked a mess so ive ordered some red ones that hopefully wont look to glaring!
I also noticed that the needle was not being held in properly by the bolt that had been overtightened and allowed the needle to move up and down about 5 - 10mm so hopefully with the new bolt in there holding the needle as it should there should also be an improvement there
So some good and not so good news today!
firstly, I no metal in reeds, im pretty sure its old damage now as i recall the marks in the carb last time so I reckon I just didnt notice it when the carb came off last time
Did a few fiddly jobs theb popped the exhaust on, filled with coolant and then started her up, yay started easy and then checked the power valve, that seemed to open right up so I was well happy, then noticed coolant dripping, looks like from the front of the head, hopefully its just a case of the oring not sat right and come out of its groove when i put the head on, ran out of time so ill do this 2morrow, then take exhauat back off to put pv cover on and then fingers crossed the bikes then a workint bike again!

Before you pull the head right off again have a check around the water inlet T piece. Depending on your hose clamps sometimes it can be beneficial to clamp on a slightly different part of the line. Also the paper gaskets between the inlet and head can break if over torqued, or leak if not snugged up enough.

Yip what jakobi said.i ruined mine and had to cut another(fiddly)gasket.next time il leave 't' on head and disconnect hoses if theres room to remove head with it on.my leak was at the front of 't' making it hard to see clearly
This gasket is not included in a top end set either

Thanks guys! Looks like it was the T Piece. I dried everything and put some water in and watched closely with my torch! I was lucky enough to have a gasket for it in my top end kit. Just wasnt quite tight enough so nipped it up and so far looks like nothing coming out, ive dried the area again and just going to leave it a few hours to make sure nothing is seeping out then put coolant back in.
nice new shinny tyre arrived today as well. Smells lovely and new!

Remember to check it again once it comes up to full temp/pressure.
Its only good news this time! Had it running for a while today and no more leaking. I only had a bit of time and the little girl was sleeping so I couldnt go for a ride but I love how easy to start it is now! Just a little poke needed. Ivr adjusted the idle and set the air screw at 1.t turns, cant wait to take it for a spin. The suspension feels much plusher to push on.
Still got to bolt plastics back on and then think about graphics.
ive sorted the rear brake pad issue out. All looking good!

Well I juat had enough money left to cover the new graphics left out of what I had put aside to sort the bike, when I spot an fmf gnarly pipe about 10miles away from me, quick bit of haggling and its mine for a very reasonable price! Quite excited about this, should polish up noce as well!

Nice thread!
My OCD was kicking in when you pulled that thing apart before cleaning the bike! Glad it all worked out.

Unbelievably it had been cleaned but it was after the.muddiest event ive ever done.
looking back I would of liked it cleaner before starting and thats only my fault and a lack of planning. Mostly as i hadnt planned on the top end build. So was only looking at the suspension and graphics and once i decided to do top end the suspension was off so couldnt wheel it out to wash it again. I made very sure that all above the engine was spotless. Also my camera seems to make everything look ten times than it is!
I fitted the rear wheel and the red hoses to carb, I need to check my sag
all graphics removed ready for the new ones. Doesnt look to bad with none imho
the carb hoses were probably the cheapest thing I got during the refresh, but I think make a big difference compared to the yucky looking ones that were on before.
I was also pleased to not be able to start the bike without choke, put choke one and it starts with the slightest of dabs on the kicker, this is great news for me as before it was quite hard to start!
quite happy with the graphics, quite expensive for what they are but I still like them.
Had first ride today. The suspension was great really pleased witn it, the best way I can describe it as is that I didnt once think about it! It just dod its job. Jetting however was off and quite frustrating, majority of riding tight woodland etc fine with smaller throttle openings but wack it open and it was horrible and struggled to get reved out. I wasnt riding to perfect this today so didnt play around much. Opening out the air screw improved it but still nowhere perfect. Since getting home I dropped a needle clip position and that alone sounds better at rest but not ridden yet,
the other problem was that I managed to loose all braking from the rear. I wonder if just a bit of sand or something got in the seals. Anyway ivr ordered a rebuild kit and will hopefully get sorted. Front was also rubbish but not been bled for a while so I will give that a bleed as well
