In a weird way, it makes me sad because a Barracuda would have been in budget, but a 1190 isn’t. | ||

That was cool. | ||

So hoping they make a crate motor someday.... R | ||

That was so fun to watch. Now I know exactly how my lump is assembled. Go Go Erik Buell Racing. | ||

That was wild!!! I wish when I watch stuff like that I wasn't a mechanic because I automatically go into the why didn't he mode? I found myself asking why didn't he double torque the headbolts? Why didn't he cross torque the cam bolts then I thought Dave you stupid ass they probably did this was just an edited version to condense for time. Anyway IT WAS AWESOME thanks for sharing!!!!!

Zac4mac - buy a lotto ticket :-) | ||

Thanks for posting that video! Now I know how to build one...seriously, getting a peek at assembly of this bad-ass machine and to my favorite tune from the CD is a great way to start the day. Time to go for a long ride to think of ways to make money. | ||

Hm... I wonder which method of engine breakin *they* subscribe to...  That looked exactly like the ever-contraversial "Motoman" breakin. | ||
| Puzzled |
So hoping they make a crate motor someday.... I can only imagine the cost of one of those. They do offer various versions of hopped up 1125's as well as 1190's. I have an email reply with a few versions of the 1190 depending on what your wallet can handle. } | ||

Syonyk - I was thinking about motoman breakin too. :-) Oh well, I guess the motors only have to last a few hours. | ||

Yeah a lot of steps were obviously left out - this was a marketing video, not a how-to. They HAVE the raw footage and I'm guessing (hoping) that someday the unedited realtime bolt by bolt build might be available to us hardcore types for whom this wouldn't be the equivalent of the proverbial "paint-drying" viewer's experience. Maybe we're seeing the future of service manuals - virtual shop foreman/instructor/head mechanic demonstrates as opposed to "read items 1-93 to assemble. Reverse order for dissassembly". :-) Also, I wonder who the tech was? :-) | ||
| Dannybuell |
Nattyx1 - That is a GOOD idea, video service manuals. That would be an benefit for dealers too. | ||
| Syonyk |
Dannybuell: That type of breakin is used on aviation motors all the time that suffer much harder service than even race motors. Think "WOT most of their life." Most of them make it for 2000+ hours of hard operation. | ||

The video is awesome, but shows only a FRACTION of what is involved in building a high output engine. Granted, it is twin cylinder and is sensibly designed, making the number of parts smaller...great idea...simple means less things to break. The transmission looks to be robust. But the time spent prepping the parts is large, and every single part needs some degree of prep work and dimensional checking...I didn't get a look at the cam drive sprockets, but can't believe they are not adjustable...degreeing the cams takes a while and is critical. On the subject of the assembly tech...he is very good with a set of T-Handles, which implies a level of "considerable " experience.....and the holding fixture was cool too. | ||

> Also, I wonder who the tech was? I think I know. I recognize the hands from the pictures of my bike build... | ||
| Syonyk |
I assumed this was a "public video build" as well - I didn't see any assembly lube being used in putting things together. | ||

Notice the 'stinger' isn't installed while on the dyno? | ||
| Barker |
It looks like thats the bike Geoff will be riding. White fender, Geoff's tank grabbers, race can, GP shift.  | ||

I thought they said it was just a used race frame they bolted the motor into just to test it? | ||

That type of breakin is used on aviation motors all the time that suffer much harder service than even race motors. Think "WOT most of their life." I've broken in a few aero engines in my time and the manufacturer does specify a method very similar to the Motoman method, involving things like lashing the wheel of a tail dragger to a tree for the WOT sessions inbetween cooling times. However, these motor (Continental and Lycoming) are very low tech with unmatched components when you compare them with the Helicon. After climbing out from an airfield, my plane spends very little time at WOT. | ||

This may be something to take to another thread, but after the engine is broken in and the rings are seated, how you run it doesn't matter - the "damage has been done," one way or the other. Either the rings have seated properly to the walls and the engine has good sealing, good compression, and good oil consumption for the rest of it's life, or it hasn't been broken in properly, the rings aren't seated right, and you get a lot of oil blowby the rest of it's life. Now, an engine may be perfectly fine with rings less-than-perfectly sealed, but it's going to make less power than one that's well sealed. I don't think the difference between the Helicon and a Lycoming matters too much - they're IC engines, they've got standard bearings, they're oil lubricated, etc. If you have metal to metal contact in *either* motor, it's bad. And should never happen, even under high loads. I'm sure someone has done the comparisons, but this really is an easy problem to test for. Get a few engines (ideally 10 or so, to reduce the risk of a single random failure skewing results). Break half of them in gently, half of them in with the motoman method. Run them on instrumented dynos through a wide range of load conditions for a long while. Measure fuel consumption, combustion pressures, coolant temps, peak cylinder head temperatures, oil consumption, peak horsepower, BSFC, etc. After a long while, say 200k miles equivalent, tear them down. Inspect the parts, get out the micrometers, and do a full measurement/analysis. Draw conclusions. | ||

Motorcycle engine that lasts 200,000 continuous miles - no rebuilds - I want one of those! EZ |
