what engine model number do you have its located on the side of the top end


Mine is a 4fu00 which is supposed to be the daddy of all topends as it use a flat top piston not a dome one 


on the replacement its a 3mb00

Not a TDR but...

My commuter DT has a bog standard "low power" 3MB top end. The project DT has a stage 3 tuned 3MB top end, with a bored out carb.

So ive been told 4fu are the bollox with 30 ish hp

Does your new TZR have a dellorto carb fitted?

Mine's the 4FU also... Totally standard French example. Does anyone know if there's any easy deristrictions I can do? I think the powervalve is deristricted as standard and the only other thing I can see is the removal of the honeycomb crap from the expansion chamber...except I don't want to cut a hole in my exhaust when I have no way of welding it back up!!

the best one is the honeycomb in the exhaust...try looking inside the exhaust and see it there is a plate welded in there....
