runs fine on qtr throtle but when i pull it right back cuts out and dies.also eating spark plugs.at the moment its in having crank seals done if its not that i have ran out of ideas your help would be great as its a sexy looking bike clean engine and fat grephics.cheers
cud the oil pump be puting tomuch oil in and how can i tel
Im no grease monkey mate so i am not 100% sure....but it does sound like it could be a possibilty because the oil pump is electronicllay controlled it could become faulty i guess causing to little or to much oil!
As i said im not sure, but someone on here will point out if i am wrong or not!
But i dont think it could cause it to cut out (unless it siezed) have you checked your HT lead...check every little things! Also have you checked the air fileter, if that is nakered then that could cause the problem!

just put a new enginine in it 03.new filter new plug new carb.i think its air or fuel related just got to end of teather with it.started wishing i never brought it well need help.im not a spaz when it comes to engines but this has thrown me.any help or ideas wud be great
wat about the little gause filters in the fuel tank and in the carb, take fuel feed pipe off carb n there should be a gause bag thing in the brass pipe wer the fuel pipe goes on, i checked mine recently and there was loads of **** in there could be part of ur problem m8 as for the ones in the tank jus unbolt the tap from the tank n urll find two of em on the brass pipes attached to the tap
And if still no luck, you could alway's check that you'r float needle is all nice and clean! You should aslo check you'r YPVS (Power Valve) to see if it is all clean as that can cause a 2 stroke to run badly!

If the oil pump is putting too much oil through there will be lots of blue smoke from the exhaust. It wont be causing it to cut out at high revs though. It does sound like a blocked main jet or possible fuel starvation. Try running it without the fuel filler cap on (as long as theres not too muchg fuel in it!) and see if that cures it. Good luck, hope this helps you.
thanks for all your replies it was the air box.to much air getting in.and put snorkol back on now it hits 95mph no prob it really iss fast.thanks to all.this site is amazin
Rofl was gonna say thats slight bullshizzle, One of the new-ish sumo'd ktm's with mods can do 100mph so i HIGHLY doubt a dt with snorkie can do 95 ha...
What, my completely standard DTR with no mods does 150mph, honest! Oh sorry, I'm talking out of my arse again, silly me!
By the way, if you had upjetted to 260, removed snorkel, and blocked off the bottle attached to the carb intake pipe, fitted an aftermarket exhaust, trimmed the excess rubber off the inlet manifold, it would have been fiiiiiiine, that's how I roll :)
