Also, another question I have is, which pipe would be better? I could always remove the muffler but it's better to have it rather than not and regret it later.

I cant get either as the moment as it's a rare find to get them in the UK and it's 30 dollars including the bracket from the US but with 37 dollars postage So that is a dead end for me until I find a source in the UK

Also is it best to get an angled filter?

Ok, I might go ahead and order the UNI. does it matter is the header doesn't have a muffler, or the shape of the header?

So the first things you recommend are to remove governor, header and high flow intake? If so, would you recommend the K&n style or UNI filter?

What filter would you guys use if it were you, from the image above? I have hooked up the tach, it idles at around 1600, and even lowering the stop screw, the governor keeps it at 1650. At full rpm I have limited it to 3000 (roughly) according to the tach anyway. Here's a picture of the...

Please don't abandon me :p Got my tach/hour meter 5 minutes ago!

Okay. I have looked at importing the parts from the US since it seems to be a bit cheaper. Which filter would you guys prefer personally? I can't decide if the truth be told.

That's what I have at the moment, size 72 jet is quite common on eBay so I guess it's a good size?

Ok, thanks for that. Should the conrod be genuine or can it be clone? Also I'm in the UK so the filters and adapters are a pain in the butt to get hold of, do you know anywhere with low international postage costs? Finally, would you/are you allowed to post links to these parts? EDIT: I...

Ok thats understandable, so what would I need to get before jetting and getting a 140 etube, along with a straight pipe and governor removal?

Thanks, that's a great list! How does removing the head gasket work? How much extra power would it gain? Also what sized jet could I use for a bit more power with the stock intake? I don't have enough money to buy the high flow filter and adapter and import it to the UK. I don't think my...

Oh OK, I guess with a bit of saving I could squeeze some more juice out of the clone. Would you mind telling me some 'micro mods' please?

It's a brand new plug so il run it for half hour and send a picture. What are some cheap mods to do? I'm 16 so not much money available but I'm willing to spend 5 or 10 pounds here and there. Do you know anywhere to get these high flow filters in the UK? I'm sure I could make a straight pipe...

I understand how they act differently when cold, but I am also asking how to adjust the mixture on these machines as I know for a fact the mixture is off.

Thanks for that. If I removed the governor (Never done it before), and made these mods, what sort of differences would I get compared to a stock GX200 (Clone)? I was also thinking about a racing air filter, with the correct adapter and a homemade straight pipe without a silencer/muffler...

I understand your point but Im not sure of the ins and outs of jetting. Hence why posting here :thumbsup:

Hey guys, long time no see? Anyway, got a new engine, picked it up from a second hand shop for £40. It's a GX200 clone and it runs. I havn't done much to it apart from change the plug (To a BPR6ES), change the oil to RockOil 4 Stroke Oil (I think its SAE 30, got it for £3 so it will do for...

It looks like I'm going to sell mine and get a clone. for a normal clutch does the engine need to have a Q or an S type shaft? What's the difference?

If I can get around 220 for my 340 I would get a Launtop 390 clone w/ electric start, as then I wouldn't need a Jackshaft, to remove the governor, get a fuel tank etc etc The electric start would be so handy for my kart as I already have the wiring for it and a battery holder on my kart from...
