yop ...I am really tempted to buy one of these....would be nice to see the difference to the YX units

I have realised there was one thing I didn't think of when ordering this engine. I sometimes ride at night. Anyone know of a solution? Maybe a stator I can buy and swap out when needed (I don't ride at night much - about 3 times a year or so, but want the option to do it if possible).

Or maybe some other lighting solution, even if I chew through batteries etc.

Elstars have this:

Hella Night Laser Lamp : hl-960

But I'm not convinced that a couple of these would be bright enough. The lights I have on it are not as bright as real ATV lights (Just a couple of driving lights I screwed on there) But they do the job on the tight tracks we ride on.

Dirtmax YX 150 Dyno Sheet

As promised guys, the sheet is located at the following link:
Urban X Motos ...............Quad Bikes, Dirt Bikes & Mountain Bikes - Dirtmax 150 Dyno sheet

As Stated the Air / Fuel is way off and thats why it only reached 14.49 at the back wheel. Stay tuned for the next results as soon as we achive the correct jetting.

As promised guys, the sheet is located at the following link:
Urban X Motos ...............Quad Bikes, Dirt Bikes & Mountain Bikes - Dirtmax 150 Dyno sheet
.

That is peaking at 5000RPM. Is this because it is measured at the wheel? The add says it peaks at 9500RPM:

DIRTMAX AVENGER 150CC 16HP ENGINE PITBIKE - eBay Other Makes, Bike Parts, Motorcycle Parts, Accessories, Cars, Bikes, Boats. (end time 11-Feb-08 12:49:44 AEDST)

And I notice it has now been changed here:

Urban X Motos ...............Quad Bikes, Dirt Bikes & Mountain Bikes - 150cc 16HP Engine

What is with that difference?

first off...the Air/fuel chart looks ok for me...second how does the engine does torque only between 3000 to 6000 rpms???...and third the peak power is at 5000 rpms ???

Whether the whole setup was wrong or you have to split all your results in half...which would make out of your 14.5 .....???

If you post charts , see that you get it right, Pal!!

How much do people charge for a quick and dirty dyno test?

I sent Max Power an Email. The dyno sheet certainly looks like the ones on the Max Power website (look further down, the first few have a different heading font):

MaxPower Performance Cycles: DYNO GRAPHS

I don't really care either way, I'm not that into it. My brief research browsing motorbike forums is in stark contrast to the usual tech forums I visit. People on the motorbike forums seem to think shouting out BS is enough of an argument. Us nerds like yo say that is BS and here is indisputable proof. . That said I don't have the knowledge to just know it is BS I suppose.

I received a response from Steve at Maxpower, here it is:
____________________________________

Hello Sean,

Yes we did the dyno, The dyno shows it only put out 14.49HP but that is because it was running rich, as the dyno shows.
Once we get the New jet It would put out 16HP Easy.

Cheers Mate

hahaha you know so little about these engines or dynoing that you can't see whats wrong with your little piece of maxpower paper.

maxpower is a timely name for these guys....

 

[Funkstick]

I now find myself hoping that this engine isn't too powerful. I bought an absolute bargain today. A 2006 Yamaha Banshee that is practically new for $4500. That means the FYM typhoon ATV this engine is going in will be ridden by my son, so I would rather it be slower.

I gotta say though for an inexperienced rider like me the Banshee is pretty scary.

 

[ducar.r.spec]

im loving the look of the lifan 150
especially that the side seems to be a replica of a take clutch cover
do they have replacement oil filters yet?

 

[SEDUCE]

guys my 140 pulled 17.19hp on the dyno at work @14,750rpm after the kitaco irk was installed with the big race cam and ported and polished big valve head on it here is a dyno slip of it, it is a old dyno so it doesnt have torque reading

 

[mxb_125]

how fast would your bike go seduce on a straight on dirt and road rufferly

Sweet!
What Carb??Jetting??What racecam??

 

[Funkstick]

Today I was thinking that maybe I didn't need this engine. My son will be using the bike now and he doesn't need the extra power and the electric start on the current engine will be easier for him.

Well I took him on a ride to show him how to use the clutch and gears etc. When we finished I went on a quick ride. I went about 50 meters and heard a noise from the engine. I stopped and looked down and oil was pissing out. I thought I may have hit a rock, but the hole looks like something from inside has shot out. Oh well, I need the new engine now. Especially after we rode it around with no oil for a while

I am running a 7.1 mm race cam and a rejetted 28mm keihein
alot of fine tunning has been done on this bike and pulls f en hard
