After I'm at operating temp (at least 220F), I can give it any kind of throttle and let it go back to idle, which it'll then idle high for 15-20 seconds, then go down to it's normal idle. It's somewhat common from the searches I've done, but I can't lean the LSN any further. I can find the perfect point for my LSN before it starts lean bogging on bottom end... Should I be leaning out the top end and then going from there?
This engine holds a tune so dang well, it starts within a second every. single. time. Stays running, too, even with a bad tune. 41001/9886 combo, #6 plug, 8mm carb insert. Fresh air filter. 25/9 VP fuel. |

Still having this problem... any suggestions? End points are correct. Carb fully closed and fully open. Tune does not change on brake.

My internet guess would be your hsn is a bit lean. When you close your throttle it revs high as if it’s lean, but then settles down once it’s been running on the LSN. |

I agree. Sounds like lean HSN for sure, likely also with an overly rich LSN to compensate.

airleak? sometimes you just need to start at a base setting 5 turns from full closed on LSN 4 turns from closed on HSN be sure to pull linkage open before running LSN in |
Have any of you guy,s ran the mephisto yet just curious to hear any feedback.

OH YEAH !!!!!!!!!

According to the Novarossi website the Mephisto is a Mantra with a different crank and carb, so unless they did some changes to the crank besides DLC it should run the same.

Is Mephisto better in terms of fuel consumption versus Mantra? |

So you mean that the Mephisto is a little evolution of the Mantra?

they made the crank a tick bigger per novas site. different glow plugs. different carb. 3 needle like the rolling. and better cooling head and they say different exhaust to use.. I can give more on this when it shows up Friday and I can put the 2 motors side by side.. jeremy

I was looking at the mantra for awhile but got mephisto when they came out, Drake has it now doing the break-in. The BTT square stroke was my favorite buggy motor ever, so I'm hoping this is similar

The only thing that make any real difference is if they have changed the crank in timing or bore etc, all the rest is the same between them. The carb could have slight difference in how it feels and tunes, but not in power. But measure the timing and get back to us. |
I have an elite 5 paired with a 41021, and a 2096 pipe. I have about a gallon and a half on it. It is a great motor but I am looking to get a little more power. Would changing pipes help in yhis, or should I attempt to remove a shim? |
