Just the facts. I work at a Yamaha-Polaris dealership in southern WV. We convinced a good customer of ours to get the 295 kit in his 2005 YZ 250.
I got to ride it for about half an hour to check it out. He had it ported for an "over-all" power increase. Here is what I noticed.
Power- Simply amazing. I have been riding 450's since 2004, and this thing RIPS! It pulls hard from bottom to top, with a nice, healthy "hit" in the midrange. I didn't notice the usual amount of wheelspin I usually get when I jump on a 2-stroke (cause i'm so used to 4-strokes), the power gets to the ground nicely.
This thing can eat up hills with ease. The most fun I had on the ride was shooting up this STEEP hill behind the shop. The YZ had NO problems, and power WAS NOT an issue. It also acted like it felt right at home being lugged around on the slower, more technical parts of the trail.
Sooooo, this morning, I threw down $1995 for a 2006 YZ 250, and plan on getting the EXACT same set-up on my machine. Can't wait!!!!!

I hear Eric has that kit dialed in. Did you notice any extra or excessive vibration in the bike with this kit?

Not that noticeable. Maybe I went into it expecting it to vibrate very badly, but it wasn't as noticeable as you might think.

I agree with the vibration level. Same as stock, maybe a little less. From what Eric said, the piston weight is very close to what an oem yamaha piston weighs.

Now we just need to get Harris to release his improved durability transmission to go with this kit. Since he plans on significantly improving reliability, maybe he could even be convinced to offer a 6 speed version during his re-design that requires only minor case machining to work???? Imagine the possibilities.... A durable 6 speed to go with a big bore kit?? I call it YZ Nirvana....

Wait, I have my eye on an eg 295 kit, but I need a bike that continues to start easily. How much harder is the bike to start now?

It fires up easy, just takes a little more force to kick. Not like the stock bike, which you can almost start by hand.

yeah it still fires right up. my problem is I'm short, and it's definitely harder to kick for me.

Short legs are not the hot set-up with the kit, for sure. Maybe Harris needs to offer this with his six-speed...http://www.shortsupp.../procedure.html

Mine is not so easy to kick, but with good jetting and an iridium plug, its a two kicker at most. I do think that expensive plug lets it start easier....It could also be due to the lightweight wallet after buying the plug.

hey man- this is jordan- i think you sold me a rear wheel bearing on saturday and saved my weekend? we had 2 yz300's @ burning rock. mines an 08 and my buddies is an 05. keep us posted when you get yours up and running. we'll have to have a yz300 convention in beckely!!

oh and these bikes are not that hard to start. you just have to kick it like you mean it. i'm not running $30 plugs either. you can't short stroke it. you have to kick it all the way through. mine starts first kick every time.

You guys bitching about starting a 295 need to try kicking a 500. You'll never complain about your YZs ever again. :thumbsup:

The 295 is harder to kick than a cr or kx 500. Especially for those of us who have bumped compression up over stock. I dont think Yamaha gave it their all when designing the lever in the first place.

Even my old 490 was easier, to a point. That kickstart lever was slick and th e bike enjoyed kicking back. This always sent your shin right into the narrow, sharp footpeg.

Not all 500s are created equal. My '86 is MUCH harder to kick than my '90 and '97. So much so that I had a decompression release machined in the head of the '86. It now kicks over much more like a 295. :thumbsup:
