doesnt your bike have an oil level dipstick?

yeah and while it's off again, look out for any muck or filter material bunging up anything at the inlet side of the carb

it sounds like a possible right side crank seal failure, lots of smelly white smoke and an engine choking on the stuff Check your gearbox oil level...is it decreasing? Does it smell of fuel?

if your chain is very slack you run the risk of it touching top of the swingarm when the engine is on the overrun

try adjusting the mixture screw, note where it is first so you can return to that point. I would guess it's clockwise to lean and anti clock to richen on this bike

Hmm did you spray through the little passageways in the carb as well as cleaning the jet?...really you should have done while it was off,

Try this Alan Put the bike in 1st gear and push it backwards to tension the top run of chain, hold the tensioner down off the chain, and adjust for 50mm slack in chain, both wheels on the ground mind. Actually the books says 40-50mm of slack

check theres a strong flow of fuel to the carb grouch

I never use the notifications myself. Dont you get email notification? I expected thats how it would work

yeah I know it was but if I had a penny for every time you have related 'crank seal' to 'hard to start'... I'd have at least 10p by now mines on order BTW

ohhh hard to start mag side seal

If it's got a #240 jet in there just stick a #250 in and away you go thats what I did and I had a bigger snorkel and boyessens, the bike ran well

Bugger its been so reliable too! wonder what brought that on?

If its running perfect as it is I'm baffled as to why you want to throw money away on a dyno...Its got a filter aleady and buying another will be wasting more money IMO If you want to play safe just put the next size jet in and enjoy it for what it is they are great little bikes. The black oily stuff is normal on these it's just unburned two stroke oil, mine used to do it too

Greetings Lee and , bet that mini is worth a few bob now then eh?

yep it'll cost you that will quill exhausts have a dyno if you want to contact them with prices...keep us informed though

Thats another downside to mine too...the mic is too sensitive

The difficulty may well be removing the float bowl screws, sometimes they will need a sharp rap with a lightweight hammer, and always use the correct philips driver.

I've got a drift X170 and the auto exposure is rubbish, try record something in bright sunny conditions and you have nothing but blackness! is it me? whats this like in bright sunshine then...i'm sure mines ok on dull days?

ebay of course

Yeah show us another one of your pullovers haha.... please

Wel it does sound like it could be the choke then armfaw...I'm not familiar with it though so sorry I cant help further...best get the carb checked out

The 125 has crancase induction, It's a more modern way

Perhaps but not necessarily How exactly do you 'Tip petrol into the carb' ?
