Okay, I know a lot of you guys were interested in my CNC heads, but they were cost prohibitive when you factor in overseas shipping. I had a concern with using +1 valves in a 100mm bore, due to the possibility of shrouding. So we finished a new head design that utilizes the stock valves to help knock the cost down, and reduce the possibility of shrouding.

We ended up nailing it! The head actually flowed 353 CFM@28" and .500" valve lift. This is better than my original +1 design. For those that don't know about flow numbers, this is not only good, it is borderline obscene! I am super proud of this piece.

Some dyno testing will be done this week, and then we will finalize the pricing. We will not have numbers that are a direct comparison for a while, but we will know if the technique is solid.

Tease!

Keep 'em coming Kenny.

I still need a XT cam so I can build a dual bolt pattern cam flange..... That will reduce the cost of you guys running my billet cams by enabling you to use the gear and de-comp mechanism you already have. My cam is the most expensive one out, but if you can go without buying a new de-comp mechanism, it might become a bargain.

Have you still got what Kenny needs Fran?

Can he do it with the cam alone or does he need the block?

If it's just the cam let me know how much to buy from you and send to him for experimentation.

I have one whole engine and only the bottom half of another engine but the top end lives in Marjani's bike, so I don't have cam/cylinder/piston etc....

I asked Kenny if he wants to buy my whole spare engine but.... I haven't heard back from him.

Its there sitting in my shed waiting.

Money is still WAY tight over here ! I would love to have both the bottom end and the complete motor. I can't remember......Wasn't there knocks or gear problems with both? For some reason I remember being afraid that I wouldn't be able to get the OE parts to fix it......

Kenny I'll be fair to you and will keep this discussion in the open public for all to see.

The bottom end of the first engine it's dismantled in like a 100 pieces all gathered in a few boxes. It has a snapped drive axle (see attached pic)

You can have the whole bottom end for free, it is of no use to me as it is.

The other whole engine has a slight knocking noise but no loss of performance at all, coming from around the cylinder head.

While it was still fitted to the bike, I took it to a reputable private mechanic not a Yamaha franchisee, who diagnosed that issue as a possible worn bearing in the crank shaft, or a possible valve issue, in either case he told me the damage would be minimal and easily rectified, however at a cost which was pretty steep, because he quoted me so much money just to open and shut the engine for inspection, that I found a new engine from an accidented bike to be the much cheaper option. Unfortunately less than a month after the new engine was on my bike was stolen and with that all my patience for motorcycles expired ever after.

Now... I am offering that engine, as is, for �200 english pounds (about $292 all in) to you as a gesture of good will and for the good things to come for our forum members once you get your hands on one of these motors. This you can appreciate is a considerably lesser offer than what I had originally asked you in the past.

I am now getting to the point where this is just a dead weight to me, my bike was stolen I am not riding anymore, I am selling my home to return to Italy and if I don't sell it here I will be forced to sell it to a local bike breaker.

Problem is.... you'd have to organize and pay for a courier with a large crate to pack it and ship it.

If I were you, in the line of business you are in, I would see this as an important investment, without one of these engines on your workbench you are slightly limited in the way of R&D for new trick parts to sell here and in other similar forums such as Aprilia, Derbi, MZ, MT03, all bikes that use the same engine, and worry not, we have 100's of lurkers here from those places reading about mods for their bikes.


Over to you.

I'll take it...... I need some help from someone over there that can pack and ship it..... I don't know what the couriers charge, as I use the US Postal service almost exclusively. I have no idea what the costs are. Do you guys have a national courier service that might be more reasonable than UPS or FedEx?

I honestly think getting the right top-end combo and a stroker crank will turn this into a giant killer!

One of the popular ways we ship engines is to get one of the large Igloo coolers, that has 2 wheels and a tote handle. We will then seal the engine securely with garbage bags, put it in the cooler, and fill the cooler with a few cans of Great Stuff expanding foam. The entire assembly will be locked into place until it is chiseled out. Is that something that could be reasonably done?

I will look for some of these Igloo cooler see if I can find one large enough and I know where to get the expanding foam. I'll let you know.
