dab33 Posted January 28, 2022 Report Share Posted January 28, 2022 Never done this on the Tz before, done a bit of googling and it's recommended, personally never had an issue with leaks before. I have bought a kit for Accu products, just wondering what sort of pressure I should be putting in? Tia Dave Quote Link to comment Share on other sites More sharing options...
bogman Posted January 28, 2022 Report Share Posted January 28, 2022 5 or 6 psi max it it holds for 20 mins it’s all good Tzs leak from the carb manifolds (bad) and the pv seals ( not so bad) 2 1 Quote Link to comment Share on other sites More sharing options...
dab33 Posted January 28, 2022 Author Report Share Posted January 28, 2022 Cheers, Did the PV seals last year, carb manifolds could be a challenge, as I still run airboxes. Hopefully the kit won't take to long to arrive from the states. 1 Quote Link to comment Share on other sites More sharing options...
bogman Posted January 28, 2022 Report Share Posted January 28, 2022 Top one is worse because it straddles the crankcase joint Quote Link to comment Share on other sites More sharing options...

Ringding Posted February 5, 2022 Report Share Posted February 5, 2022 Your question has been answered anyway but I wanted to join in! I'd not ever bothered before the last rebuild on the LC. It turned up a leak on one inlet, which probably would have had me scratching my head over running issues. For the time and cost (very little as I got some 3D printed stuffers) it was well worth doing. I also used 5psi and looked for it holding over 20mins. Let us know how you get on with your kit. 3 Quote Link to comment Share on other sites More sharing options...
bogman Posted February 5, 2022 Report Share Posted February 5, 2022 Yeah it only needs 20 mins there is a guide online from a chap who raced competitively in ama on the tz. it’s basically a guide on running and maintaining a tz with contributions from lots of racers. I’ll see if I can find a link 2 Quote Link to comment Share on other sites More sharing options...

DougW Posted March 8, 2023 Report Share Posted March 8, 2023 Centre YPVS Power valve seals leak at 5 psi , making a squeak , which changes note when you rotate them . All new seals and bushes , power valves have been matched to the barrel porting . Should I be worried about this ? feeding it from a 5psi regulated air supply that seams to be the only leak.

Personally I wouldn't be worried about that leak. The whole area around the YPVS expands when the engine is running that maintaining a gas tight seal is unlikely 1 1 Quote Link to comment Share on other sites More sharing options...
