Thanks for all your great advice Copemech! Today was the bikes happiest day and the worse for my knee! I oiled the air filter and then replaced exhaust O rings. I pulled the fuel mix out 3 turns as you described and the bike ran great with no backfiring. No excess of smoke either for once, almost invisible. This could have been the ideal setting but i'm scared of seizing the bugger so I went another half turn to the rich side which made things a little worse and visible smoke. However I have obviously put the carb back on at the wrong angle and couldn't lift the choke. It started anyway no problem first kick, and it is warm, but this may suggest it is too rich as it doesn't require choke!? The second time in as many days that the kickstart has kicked back. Hitting an already brusied knee at the exact same point on the handlebars hurt! I now have a purple knee New technique needed lol

Thanks, I tested the fan with a car battery and it worked! I then put it back together and the fan worked on the bike too! Must have been a dodgy connection. I haven't oiled the air filter yet and the exhaust is leaking where two of the parts meet. I'll try and sort these before adjusting the fuel screw. Would a blowing exhaust cause the backfiring?

Seen as the bike isn't worth a great deal I may have to find alternative solutions to the fan and regulator problem! If both are indeed buggered as I fear they are! Is there other options for a voltage regulator? A fan motor will be easy enough to find and aftermarket attach lol.

I'm guessing the voltage regulator is knack'd causing the motor to burn out. I'm sure I was reading 50v DC! That can't be that high can it? Bike not back firing as much as I thought really. After listening to a lot of bikes on youtube, they are often quite pop sounding anyway. It is a bit more severe on mine though!

Hey guys, I'm back on my week off again after 4 weeks straight! I have had time to play with my bike again this week! I took the entire engine apart and inspected and rebuilt. I replaced all the bearings as they were cheap, other than the mains which appeared to have been replaced as the seller advertised! No gaskets had been replaced by the last owner just blodged with silicon! Some washers were missing between gears in the transmission. My noise was the ratchet on the kick start not fully disengaging! A bit of spring bending and it now does. It seems the previous owner had removed the flywheel by hammer and chisel I used a cheap

I'm sure there is but I find the best way to learn how to do something is by doing it yourself! And learning from any mistakes/problems you encounter. I've never had to pay someone to do anything on any of my cars but it took time and energy to learn and as Cope says there is much more of a resource on the internet for cars. I will likely see what is wrong immedately but things like play in the bearings/piston is something you'll only know after having a few bikes, armed with a little starting knowledge helps me eliminate potential problems. As I am interested in learning about any bike I ride, this cheap one is my best bet. I'll get round all its little niggles eventually.

Yeah all new including drive gear. All check it all out. My noise could well be just the fact its all together wrong!

Thanks guys I will delve further this weekend. I bloody hope it isn't the water pump. I have just rebuilt that with all new parts and they ain't cheap!!

Oh and can anyone comment on the noise I hear every fly rotation. A very soft clunk or click at the same point of rotation each time. This is with the cylinder and piston off so nothing to do with them. Is this just the kickstart?

Thanks, No I didn't detect up and down movement just rotational, which is the bearing within the con rod rocking slightly. It is surprisingly still on piston A. The engine seems to have very good compression as it is hard to kick but starts first kick. I was assuming this meant the rings and piston were ok, hmm. I think I will proceed to open the job lot to be honest as the previous owner seems like a right cowboy and I'd like to know what else has been bodged. When I lifted the cylinder off the last owner hadn't bothered replacing the gasket, even worse hadn't bothered to scrape off what remained when he opened it! So it had about a 1/3 of a gasket on! I fear the same will have been done throughout! Darn though, I was hoping this would be just bearings! Pistons are getting a little expensive for an old bike!

Me again, Guys, I have removed the engine today and I am going to begin replacing parts of it within reason. Is there anything unusual I should expect? I guess my first question is how much play would you expect to find in certain parts. I removed the cylinder for today and grabbed the piston. On both the little end and big end of the conrod there is no noticeable upwards/downward play, I assume this is where it really matters. However if you grab the piston in your hand and rotate clockwise/anticlockwise there is a little play that way at both sides of the conrod. Also with the engine removed if I rotate the fly then you get a small clunk every turn. Is this normal? Something to do with the kick start mechanism? I'll be opening it fully next weekend but an idea of what should and shouldn't be would be good lol. The engine had a high pitched, every stroke, rattle before hand. It sounded a bit like a bee or something like that!!

Thanks again, I am sure the backfiring has come from the fact I have a new plug in. The old plugs gap was 0.8mm and I have changed it to 0.5mm. I will need to adjust the timing and tinker with the mixture screw. I have since decided I may as well go the whole hog! I am going to strip the rest down too, whip the engine out and replace all bearings and such. I am interested to see how it all works/goes together and I don't have all the helmet/transport yet to ride it anyhow! I'm back to work Monday though for 4 (hour intense) weeks before my week off again! I'll keep you posted and again thanks for always responding so fast and helping the newbie I'll return the favour to others before long!!

I budgeted for

Should be a budget for a decent bike that mate. Best posting a seperate thread asking those questions. A which model would you get one! You will of course get biased views from everyone! Just take note of the bike they ride when they suggest one My Sherco isn't good lol. But I knew that when I got it, it needs more work than I first guessed but I am happy to do it! It looks fairly new and will feel new when I get the time to finish rebuilding it! You could have good and bad luck with any bike I guess. Best to go ride a few ideally mate and see which feels/looks good to you. A decent trade place should let you have a bash. Just learn to ride one before you buy. Any places you can hire and ride near you? There is a place called Bumpy near me, I used to live on the same road. I now live only 15 mins away. They let you have a go for

Hi mate, See here for a guide. Waynes Corner I believe you should put less oil in when you are just changing as you never get the full amount out, where as rebuilding them they will be dry.
