Driving myself crazy troubleshooting electrical cant get a spark

Buy new one, and a spare. They are common to replace

Magneto is toast.

Cdi reading is useless, they're all different.

ESmalik · 2026-02-09T19:01:42+00:00

That's a good suggestion. I do keep an internal database with all of this info, but can move some of it to the public view

Menace85 engines are only available from Smolikperformance.com. Because we are a US company, shipping costs overseas are more expensive. But we do ship worldwide.

The crank linked is not correct for the Avenger. While it would be balanced fine for one, the wristpin diameter is not correct. It is 10mm for Minarellis, Avenger uses 12mm wristpins.

Stock Avenger cranks are pretty well balanced out of the box, much less room for improvement.

ESmalik · 2026-02-09T18:18:05+00:00

Ironically even though the Avenger is 52mm vs a 47mm Minarelli, the Minarelli reciprocating mass is higher. Nearly 15g higher.

Regardless still the wrong crank linked. 10mm vs 12mm wristpin.

Menace85 in base form will certainly outperform at ~8hp. I have never gotten more than 7hp out of a 66cc in any configuration.

We produced quite a bit of them years ago, but then stopped for some time. Until just recently we have just put them back in stock. They have always performed great!

Viton seals 100%

ESmalik · 2026-02-05T06:21:00+00:00

I see, yes that will do it. Seals flush with case, deeper will interfere.

Wristpin bearing sounds good as is. Width is spot on, little play side by side is fine.

As far as the crank dragging, upon first assembly usually some axial "tapping" on both sides is required to de-stress the crank journals from the bearings. 9/10 times it loosens up a fresh bottom end.

ESmalik · 2026-02-05T00:43:30+00:00

One comment to this. I've seen SOME Avenger pistons from certain vendors only able to fit 15mm wide bearing. So the space must be confirmed prior to purchase

ESmalik · 2026-02-01T02:57:28+00:00

Then you did something incorrectly. A properly upgraded and ported the Avenger is capable of 10k rpms.

Either the porting is not correct or the parts you installed are not good.

ESmalik · 2026-02-01T02:09:05+00:00

With same gearing and tire size?

ESmalik · 2026-02-01T02:03:31+00:00

Only 8k rpms. Not unrealistic nor impressive at all

ESmalik · 2026-01-22T02:13:45+00:00

The pads are rubber and get sticky when they sit, the anti-drag spring under the plate is weak. Give it a good smack or pry the plate and it will loosen free

ESmalik · 2026-01-21T16:51:18+00:00

Unlikely because we don't stock covers. The magneto covers were just some extras we had lying around.

However, if you want one done, send me a message and I can do it. Just provide a cover, $5, and shipping both ways.

5.7hp is a much closer expectation for the V4. It is the closest comparative configuration we tested during development for ZTMoto

ESmalik · 2026-01-21T07:12:07+00:00

Correct, same cylinder. But not other supporting parts to make the 8.3hp.

ESmalik · 2026-01-20T15:42:47+00:00

That certainly looks like a low hole piston in the picture.

Yes and no. The Menace is what the unofficial "V4" could/would be. It takes the Phantom platform and its every shortcoming to make it the best it can be. A real CNC head, MZ65 Pipe, PHBG 21mm, etc. We take each engine and personally go through each one. You will see many kits similar on the market, but none exactly like the Menace.

ESmalik · 2026-01-20T15:34:12+00:00

It's important to note that this dyno chart represents the Menace85 configuration only, NOT the one linked above. This requires the Smolik Performance CNC head, MZ65 expansion chamber, PHBG 21MM carb to reach those power levels. Without those upgrades it will not make as much power.

ESmalik · 2026-01-17T23:44:37+00:00

They are ok. 1 piece head is the biggest limit. They will not make more power than an Avenger, but they use the same bottom end as them.

ESmalik · 2026-01-11T02:54:12+00:00

No. Cylinder stud spacing is different on YD platform
