Does anyone know the main jet and pilot jet sizes for TDR/TZR250 ? I have some carbs coming soon so need to know where to start with settings .

Get the manual of the right bike :  TZR250 1KT / 2MA / 2XW... and read the carburation specification...

Can anyone tell me the standard size main jets and pilots for TDR/TZR250 please

TDR250 TZR250 R1Z250 has different carburettors & setting.

Put the TDR250 carbs on the R1Z yesterday and they are a vast improvement over standard, miles more grunt but it could be that the originals were jetted miles out, now just need to sort the leaking petrol tap and change the 14 front sprocket to a 15 to give it a litttle more top end.

I'd leave it alone, I ride an R1z at the moment and its awesome. 45hp right where you want it at 9000rpm always in the power, perfect in the road. The speedo is broken so no idea what speed its doing but its great.

I'm pretty sure it has 26mm carbs, probably restricted cdi and pipes, not worth the hassel for what 5-6hp?  Compared to my race 2ma it doesn't feel much slower and you don't need to rev it to death.

[howARD]

It might leave as it is for now as I have just bought another that i can butcher instead 

[jools]

Make sure the carb slides can open right up - some carb tops had a restrictor in that prevented this - although I don't know if that applied to these bikes.......??

[howARD]

I've sold the good R1z today to a mate who is top class restorer , that leaves me with the shi**er to restore, competition is good plus he might be able to help me with my bike.

You may just want to check waht CDI you have fitted. If you have a 3XC-30, this was the later 'restricted' model, limited to 40bhp. Previous CDI's (3XC-00 and possibly 3XC-10) were the full 45bhp versions.

If, by the remotest possibility, you have a proper 3XC-70, name your price...

[howARD]

What difference will a 3XC-70 make ( no i don't have one ) do you know what power they make and what money they sell for ?
