Excellent. cheers

Some great replies chaps, thanks very much. So if I change my barrel back to the correct age related, I will need to change piston too? Or would this be good practice anyway?

What bore should the barrel be, on a Sherpa 250 198a? The barrel and head on mine are from a much older bike and I’m looking at getting a replacement. Need to make sure I get the right thing. Thanks for any advice

Excellent comments once again chaps. Cheers

Hi all. Thinking about getting the frame powder coated. A couple of questions before I do. Firstly colour? Stick with the blue or go white? There is a frame lock stop missing, so do I chop the other one off or weld on the missing one? Footrests, do I weld on new brackets, for modern footrests, or will modern types fit on existing brackets? Any thoughts on this very welcome, cheers.

Good tip, many thanks

Update on spark problem. Bike was bought as a non-runner. Points cleaned, carb cleaned, fresh premix, couple of kicks and she fired up. Thanks all

Thanks all, points checked and cleaned, 0.4 gap, opening fine. Big fat spark. Sometimes it's the simple solution.

Cheers, I'll give all these a good check over. Difficult to see anything through those little windows on the flywheel lol. Thanks for the advice

Hi all, it's probably been asked a million times, but I've got no spark. Is this just a simple fix, like points reset, or am I looking at reseting timing? Also is it easier to set points with the flywheel off, or am I creating more problems? Don't want to start ordering too many parts/tools I don't need. Big thanks for any help

Sorry for such a late reply, I have been away. That is brilliant information. I think you have covered everything. I will get back to you if I need any more info. You are a gent sir. Thank you for your time

Hi thats great. Good pictures, but havent got the spacer or the oil deflector. Nightmare! I know I am pushing it, but you couldnt give me some dimensions so I can machine some myself. Pretty please?

That is exactly the info I needed thanks. If the photos are not too much trouble that would be great, just to get a look at that spacer so I can get one made perhaps. Sorry is it longer spring after the damper rod?

Any help gratefully received. I have recently taken apart my forks on My KT250 to replace the seals and found no springs inside. sourced some new springs, but didnt realise they were so small and they are in two parts. Looked at an exploded diagram of the forks and it seems there are a lot of gubbins inside that I havent got either, spacers and the likes. Can anyone help with this because I am not sure how they line up inside or what else is needed. I have a workshop manual, but it doesnt help much really

Thanks for all replies. Took the carb apart again after having the petrol tap on and the float bowl was dry this time. Fiddled about with it again and put it back together. Kicked it over and thought there is something not right about this kick start. Drained the oil took clutch cover off. Noticed that the return mechanism stop was wrong side of the holding pin that screws in from the underside. Corrected this (very fiddly) and refilled oil. Kicked it over and sprang into life first kick. Running very nice indeed. ( for the time being)

Thanks for that, but why do you think it is flooding?

Yes the slide has full movement, but the plug has been wet when inspected.

No it was a basket case. Has a very strong spark though.

I am going insane! I just took apart my carb for the 5000 th time, because I am having real problems starting the bike after a rebuild. Would you believe it, noticed on the side it is Dellorto PHBL 26 and not 25 as stated in the manual. Took the digital calipers to it, in case it was my eyesight and it is 26mm intake. My question is, will this make a massive amount of difference and is this the source of all my woes. Please help, someone please. The men in the white coats are coming.

Thanks to all for your replies. Can't believe I have been so thick, but coming from a time when I was taught half imperial and half metric in school. I decided to weigh one litre of water and low and behold it weighs one kg, who knew? Something I was never taught, but talking to a physics teacher I work with, basic physics!! However oil is thicker so the top answer of about 1.5 litres is right. Thanks again. We can now breath life into another dead Fantic.

Very very slowly putting my 200 back together. Any ideas on how much gearbox oil goes in. Drained the old oil from sump. In the manual it says to pour gear oil in until it overflows from oil level plug on side casing. I have already put a litre in and no sign of overflow yet. Oil taken out only measures half a litre. HELP

Ok thanks for the responses lads. Problem now sorted.

Ok cheers. Any idea of the dimensions and material? Don't suppose a nylon one would hurt would it? Anything similar on the front or is it a straight through spindle?

Any help on this appreciated. Some time back I bought a TX 250 with a 200 engine in bits. While putting the rear wheel into the swinging arm, there seemed something missing. In the bits bin I found a nylon sleeve that fits inside the hub. Am I being a numbskull, does this belong in here or am I missing something?
