This is my second bike, a 2004 Gilera Dna ,it has run like a dream since i got it 2 years ago , the other day i was driving home in the heavy rain and it just dyed on me , and refused to start , i managed to get it home to have a look , i noticed the spark wasnt to good , i replaced the plug , started up just fine , then it died , it will start but it will no idle for more than 10 seconds or so
Its getting petrol to the Cylinder , so im taking it it could be the HT leads , or the CDi , any thoughts?
it was raining very very heavy that day
Interesting... That's a dirt bike correct?
Its a Moped that looks like a Motorbike . Has a Wider rear tyre the the Suzuki Gs500 .. 140 compaired to 130 . and a wider front tyre than a Suzuki Hayabusa well mine does , i have a 140 on the front to0 * stock is 120 , but i pushed the boat out , its automatic , its a stock 50cc , with bigger carb and Head kit to make 70cc . can go 60 miles a hour *indicated* on a flat bit of road , Stock 100mpg ish , as limited to 30 mph
i fill mine up with 6 litres every 5 weeks or so, 2 miles to work and back 6 days a week , and general riding around . so maybe 70-80 mpg
2 stroke single cylinder

Im not the ghey kid, but thats what it looks like
dude, i'd ride that! :icon_mrgreen:
Its nippy and squeeks like a porn star , i bought it back in 2007 , it was 2004 with 2000 miles , and i paid 700 quid for it
must be a european thing eh? something i'd have a hard time getting on this side of the pond.
Well its a 2 stroke . but isnt running at the moment , hence the help :P haha
wish i could help. i've not any experience there. :icon_mrgreen:
id check teh ignition trigger/ in whatever shape or form it may be
Lol I know whats going on.
I used to have a TVS Champ 60cc bike in India that did that in the heavy rain.
Question is it a 2stroke???? (never mind its a two stroke - I am 100% sure now that its water in your carbs/intake)
First check the carbs.. water gets in there and f%$ks it up (especially if the intake is behind the front wheel somewhere). You need to dry out the carbs. Clean out the plugs. Dry out the cylinders. If its a 4stroke, check the oil with water.
What happens is that in heavy rain it sucks in water.. and you basically kill the engine, it doesnt hydrolock but it wont start.
You should have carbon crud all over your intake.. give it a good clean and dry it out.

Ill be damned, forgot completely about that one
Thanks dude , i shall be doing that on my day off :)
Does it have an auto cut-out if the 2st oil gets low??.
AFAIK small displacement 2-stroke bikes like these don't come with a cutoff system if oil is low, you just get a red light on your dashboard that means, "hey mate put some oil in here ASAP", but no auto-cutoff, I had quite a few 50 cc's (the principle is the same) and it's always been like that.
Best of luck Jay, and BTW this isn't best season of the year for riding in the UK, is it :icon_mrgreen:
And what's more, you should very well know that nothing good or reliable can come from my place. Ever. :D
No it doesnt have the auto cut off , that would be sweet , when i bought it off the kid , i had almost no oil in it , i started it for like 2 seconds, and cut it off , so it started with no problem ,
its a awesome little thing , not had a problem with it , i no that they say there really really unreliable , but i havent had any problem , thanks for the good luck!
Thanks guys , i stripped the carb , and cleaned it all out , then bought some new Oil , fresh Petrol . started first time , rus as strong as ever .
Thanks :)
Update: Rode it half a mile or so , and it did the exact same thing and wouldnt start again , im starting to think its electrical

Did you check after replacing the plug that the spark was strong?
Yep, lovely and blue ., i hadnt replaced the plug since i got it , so i thought it needed it anyways , a lovely tan colour, it has been rejetted spot on
Sounds electrical to me, something breaking down or going O/C as it warms up. It might be a known issue, try the TwistnGo ir Gilera owners forum for advice.

Well , i was thinking today and thought well ill check the air filter , it was coverred in oil and crap , so i ran it in my garden reving it to 10k and stopping , 10k and stopping , then took the filter into the kitchen washed it with washing up liquid and warm water , dryed it , ran perfect again , took it round the block , seems fine to me , but it might chicken up again , im ordering a new air filter , it did seem the engine was being choked , however i should be buying a little 4 stroke 125cc endro copy . and end up selling the dna . its got 3000 genuine miles on it ,. and i think it would be a kids dream ,
Thanks guys!

Hope the new air filter solves your troubles, Jay_wolf.
Don't mean to be a thread whore, but does anyone else besides me think that is just the sweetest looking little 70cc?
This is the kind of bike 90% of the people in the US who bought those craptastic Chinese 50cc scooters last summer really need. Much more stable riding postion and must handle 100% better over broken pavement that those tiny scooter wheels.
Well they make the 2 stroke 49cc Dna . but with a Mallossi head and carb , is a 70cc , which mine has had done to it, mine is also the water cooled model , with auto choke, and oil pump . so u dont have to mix
or they make the 4 stroke 125cc Dna , but with a new head and carb , is upgraded to 180cc .
I prefer 2 stroke as it is , and it weighs nothing , wide rubber , disc brakes front and rear , yea its a nice little thing
if i could get this in the us i would buy 2 of them for me and the wife to sport around town on. I think they look awesome.
I use my for round the town , no gears , and the fastest road around here is a 50 mph , and the dna can do 60, takes ages to get from 50-60 being there is no torque . but from 0-40 rapid , i do love it , its a Paggio *spelling Engine . so it is relabile and parts are easy to get hold off
i would bet that if this was sold in the us they would sell a shaZam! load of them.
Got up this morning , from my girlfriends house , went to start it ... that same damn thing its being doing , so i left it there and walked home .. grrrrrrrrrrrrrr!
just kick it. :icon_mrgreen:
