Not opened my bike up properly for a while as there isn't anywhere that i can on the way to work, but today when i went to get fuel i felt like giving it some so on the way back i went the long way home even though it was freezing (mums car read 0C just before i went). So i opened it up flew past a few cars and then i realised i've lost 5mph off my top end. I reckon that means it needs new rings in, anybody got any other ideas on what it could be? Cos i use the bike everyday to get to work so it will really **** me up if i have to strip the engine and if i do have to strip it and for what ever reason it takes more that a day it means i will have to push bike to work and i can't be ****ed with that lol.
Ahhh **** take it that means a strip down is needed :( don't have breakdown cover lol not going over 3 miles on it at the moment so i will just have too grit my teeth a push or borrow the quad from work and stick in in the trailer :D (only problem is it aint road legal lol). pfft it ain't cold you tart get tough lol :P
You know when you spray an aerosol spray, even i summer .. like letting off with a full can of silicone spray all over the bikes metal bits after you've washed it ..
... and the end of the spray tip ices up ? Freezes your pinkies .. yea ?
That's how Air Con / chiller units work .. the atomisation of the liquid as it sprays steals all the heat from the air / tip around it ...
Air gets sucked through your carb, then as your petrol comes out of your jets it atomises .. This can steal all the heat from the tip of the jet .. which can then start to form frosty lumps on the end, which then f*cks up the flow & spray pattern .. Makes bike run like a dog ! Can happen in summer, but winter cold air makes it worse !
Old skool Kawasaki's used to be bad for it .. a fuel additive was the only way to stop it happening in winter ..
So covering / storing the bike in the warm, wont solve it ..
Just chucking some ideas at you ... Unlikely to be this on your DT to be honest, as later 04 on have a warm water circuit flowing through the carb to stop this happening ..
I don't know if earlier ones did ?? I suspect they have ??

yeh defo try a comp tester like sy says, yeh all years have 2 rubber tubes that come from the cylinder head and circulate through the carb stopping carb iceing, also might be worth checking your powervalve is set up properly on the pullys as the cable stretch after time, if you have been ragging the bike it may well be the piston and rings but might not
little question, have you changed your chain and sprockets since you last got 80 out your bike? larger rear sprocket or shorter front will cause this too
Nope not had to fiddle with any of that it had just had new chain and sprocket when i bought it so it would pass its MOT, and i've not ragged it to be fair just open it up when i can to have a bit off fun.
sims its an X reg, i suppose there is a slight chance that could of happened as i was fiddling around changing the dash bulbs the other day so its a possibility. as for sprocket size i wouldn't have a fookin clue as it was on when i got the bike. crazy i will have a go at that on wednesday if i get time
