@Mightyman yeah that's bad haha

@Calum I'll upload some pics of it soon see what you think

@britshgigolo It could just be well worn it's service limit. I'd take it to an engineering firm to have it examined, make sure it's within tolerance.

I've got a spare complete yz engine but in parts in a box. Do you have a picture of the gear you require? I can take a look on Saturday

I like 34:1 or 32:1 if your romping it, it's a shame the gear ratios are so short on a YZ. If you keep it fuelled on the over run, just a blip or 2, you can expect no issues, provided the engine has the correct fuelling mixture! These engines are awesome, and can withstand abuse, just got to keep it setup correctly.

Yeah there's 2 on eBay for £20 ATM

link text I've been reading today a lot about the reeds , interesting technology , pretty simple but great. Loads of videos on youtube also , man did tutorial how to get max of them.

@scotty not all dts use the same carbs is what I was saying mines a tm 28 if yours is a vm 26 then i don't see why it wouldn't fit

@Calum Aye Calum, cheers, I did bled system and issue is sorted. Water pump was airlocked, that's all. The thermostat should fully open about 78 degrees.

I'm not sure and i can't see it in the service manual

@micheal-cox I have not found that the powervalve works properly in neutral. Best thing is to take the exhaust off and manually set it and disconnect it from the servo.

I've got a dt re 04 it starts mainly on choke it like new every thing is like new but it's just stoped tickin over what should I do

@Darty cheers mate I just want 1 that's going to last haha and best performance

@Ricky Yeah water is not going to get the oil out bud. You need something that will drag the oil out. But not petrol. Use some sort coolant flush.

Alot of our tuners up north will work with you internationally, postage might be £25 or so. Interesting as a modification, but Jasil state no changes in mass, I'm still tempted with one but unless this 'Racing' style crank is lighter, you are better off having the Yamaha crank built with a forged rod, you would have to try really really very hard to blow the bottom end apart on a DTR. These Yamaha cranks are solid from factory, any crank will be balanced. Will be interesting to see a comparison.

Should see a blue haze from a two stroke, that's engine oil. Black will be transmission oil, or excessive fuel.

ok ty calum for all the helpfull infomation its a great help

That is a lot of stuff for 55 quid. Loads of spares. I would buy it for a spares.
