DT125LC Mk3 No power valve where there should be one!

[JBelly]

Hi all,

I am finally sorting out the old DT125LC (1986) we've had in the shed for years. All stripped down, repainting lots of bits and in evenings doing the engine. Will be replacing seals and bearings etc. But the cylinder is worrying me since there is the space for the power valve with both end caps fitted but on opening it up it revealed there is no power valve in there. When we bought the bike years ago it was running and tootled around the farmers yard I bought it from but was in such a state that it was not fully testable. So I'm wondering if once rebuilt whether the engine will run well without a power valve fitted or will I just have loads of issues getting it to run properly  like that? Lots of carbon build up on the inside of the end cap I took off so looks like it may have been run like that for a while. Was this possibly something owners did back in the day?

Anyway, hoping someone on here has some thoughts.

Tried looking for a second hand power valve to put in there but they seem quite rare.

Can upload pics if needed.

Thanks in advance.

Hello and welcome! I will fit the power valve, is it difficult to buy try at a motorcycle disassembly, local websites for motorcycle parts or eBay where you have the best chance of finding the parts. Good luck
