A side note after cleaning it with brake cleaner non-chlorinated real well dust the whole IP head area and where you think it's leaking with baby powder. The leak should be easier to find.

The TM calls it the fuel control unit assembly. It controls all levels of fuel from wide open throttle, idle and shut down. There is an o-ring for sealing the assembly. When that o-ring leaks it dumps fuel into the lower part of the IP and then back into the oil pan. If the gasket on the timing...

Yes you need to do a good cleaning with brake clean non-chlorinated and pinpoint the exact place of leakage. 99% of the problems I believe that our fuel related mixing fuel with oil come from the head. Yes the booster pump add fuel to the oil but we're not talking about that now. Unless there is...

Thread remind me of a problem I had. My 915 was getting weird stuff growing on the cap and steel chain. Removed the chain took care of my problem. I do catch myself double checking that I put the cap back on tight after getting fuel so the cap is not sitting lonely on the street somewhere.

While you are correct about the red tooth being on the pointer for when we are only removing the head it's one of the three timing marks on our engine. If the injection pump has never been disassembled and the head removed and install correctly then there should be no problem. Just because we...

One of the pages of the TM you showed is when we replace the whole IP and how to set it up. When first installing the IP to the engine the timing is not going to be correct. The other is showing corrected timing with harmonic balancer on its Mark the advance window on its Mark and the head...

Just reminder when we bypass the FDC it's a good idea to put a pyro on there cuz you're going to have to adjust that fuel. Most cases we have to reduce the fuel to keep the egt's down. Also if and when you bypass you have to see still keep an eye on that oil cuz the booster pump can also put...

Just looking.

what would be real interesting would be your dyno a stock fuel system with the FDC hooked up and the LDS checked for egt's versus an ldt.

Talking about RPM the first LDS that had a governed speed of 2800 RPM then the other models they dropped into 2600 rpm @ rated horsepower. No matter what, you want more horsepower build a hotter fire but have to deal with the heat The design of the multi-fuel engine we're working with is poor...

Sounds like a good plan. Sounds like you got the pyro covered the only thing I would add was get a new oil feed line to replace the old one when you exchange IP's

Well a lot of people are happy with an FDC bypass and a good tune a pyro on an ldt they're happy with the way they run. You can turn the fuel up on an LDT and it will outrun a stock LDS pump but the problem will be the heat. Also it seems like a lot of people don't even want to spin it up to...

I think that 200 horsepower is a little unrealistic from just a rocker arm change. One of the reasons the LDS had to be spun at 2900 RPM to produce the higher HP.
