again, the thread title references 2019 114 engines. Lots of comments but how many of them actually have 114 M8 engines?

 

I think your plan is the best that can be done. I’m empathetic to the entire situation having been down the same path myself... several times. Under the circumstances you and everyone else still dealing with the issue of sumping are doing the best that can be done. Best wishes and good luck with managing the bike to its best possible performance.

 

A cheap idea that might be worth considering. Find a used Powervision on eBay. Don’t worry about mating it to the bike. Mount it to the handlebar and plug it into the ECU port under the seat. You won’t need a license from Dynojet for tuning. You can just use the PV display as a multipurpose, multifunctional set of engine monitoring gauges. On a single screen you can observe ETs, Head Temps, Coolant temps (for liquid cooled bikes), spark knock and dozens of other parameters on the engine’s performance.

And so long as its not mated to the bike, you’ll have no impact on the bike’s factory warranty or ESP. You can also make the PV easily removable with various mounting options. If you’re interested in really monitoring your engine’s performance without impacting your warranty, installing a used Powervision without a tuning license is the easiest and least expensive way to montioring every aspect of your engines performance. Just remember for the M8 engine to get the canbus wire connection and you’re good to go.

 

Thank you sir, frustrating....you bet but things could always be worse!

 

Good idea, I have an FP3 from my 2017 SGS, I will watch the temps on my phone. What would be an engine and oil temp to be concerned with? I assume in a sumping occurence these temps would be up over normal just not sure what number should cause concern.

 

I can’t speak to oil temps as I never monitored them at the dipstick. I did monitor ETs as measured by the sensors that send signals to the M8s ECU. For liquid-cooled M8s, ETs above 300 should be closely montiored. If they eventually drop below 300, no big deal. If they get up around 320... and stay there.... IMO, those are early signals of sumping or some other engine issue. If ETs rise above 340, then IMO a liquid-cooled M8 engine is struggling and is likely having some type of engine problem. IMO, a strong candidate for the rootcause is sumping once the ETs get this high in a liquid-cooled M8.

if the temps are 340 or higher, its very easy to confirm if sumping is the cause. Just pull the dipstick (be careful because it will be extraordinarily HOT). If the dipstick now reads “ADD OIL”, you just confirmed that sumping was the reason for the high ETs.

 

I installed my A1 vent dip stick and ride above 5000 rpm in shot day and no signs of sumping. ET hi temps were 360
and oily temp were 245. Had it on. The dyno for a pull and got 102/82 with fuel Moto header and hi rollers and power vison

 

Can someone please post a link to the venting dipstick, scrolled through dozens of posts and didn’t see a link.

Thanks - and yall really feel like this prevents, or helps prevent sumping?
