Here's a video we took earlier this year of us jumping. 1st up is a 07 Joyner 250 modded, 2nd is a Carter Talon 150(Highly modded) , then and stock single speed HH250 last.
Holy dirty diaper! I KNOW that hurt when he landed! I am amazed at the height of that buggy! Looks like it was shot out of a cannon! He had to have a heck of a running start to get that high or, he ended up on his roof!
He was about one (1) foot off the ground. That picture is a bit deceiving. He started in the dirt area and then launched off the grassy area, which is higher, which is when I snapped the pic.
One thing I will add - eggy said he didn't know he had gotten off the ground until I showed him the pic. That shows you how smooth that suspension is.

That eggy, he's a character....
As far as the 150cc versus 250cc issue... It all depends on the buggy...
ACBlind's Yerf-Dog 150cc is a flying little machine. His machine is modified with just about every option and can spank a stock 250cc Joyner. A few major things to keep in mind:
500 lbs / 150cc versus 1000 lbs / 250cc... The 150cc wins every time.
I've driven modifed 250cc buggies and modified 150cc buggies. The 150cc buggies are usually quicker off the line with the 250cc catching up about 1/4-mile into it...
After that the 250cc beats the 150cc...
Climbing and a dual range H/L tranny are hard to compare 150cc v. 250cc. I've never seen a 150cc with a two speed tranny.
Me, I love the thought of a TRUE 300cc buggy. Not a 250cc bored to a 280cc.. Put that in a strong and lightweight frame and we're all set.

Pete maybe I need to tune my buggie like yours, I'm not close to 55mph, I've never tested longer that 2/10 of a mile, and 42mph was what I reached. That was stock, and my mods are for accel, and climbing. I think the Joyner is a little underpowered, but the other buggies are UNDER BUILT. Tom says it's the toughest buggie he's seen. So if your really off roading, wouldn't you want the toughest buggy, 'cause I'll tell you what...in the toughest conditions I bet I got the fastest 250 buggy.
1. I think you are too light on your sliders and limiting your top end. You will still have enough torque in low range. 2. Unless you are running a larger carburetor or modified exhaust, your jetting seems too rich. 3. You would be surprised how much drag you reduce by going with tall tires up front. 4. I am considering the Buggy Junkie 12t transmission sprocket mated to 25" rear tires, but there's no way I would run such a tall tire even with my stock 2008 gearing.
Where I ride the lighter rollers are great because after you climb the hill you have open space where you can get on it. I would spend the day shift with heavier rollers. I've tried the 18's and like the top end, but the climbing wasn't aggressive enough for my taste. Now the taller tires they'll benifit me either way, and I plan to put 22's on my Dune mod, so buying bigger tires at that time will work out great. As far carburetors the next buggy I buy I want EFI, I'll leave the jetting to the pros.

Did someone say "Air"?
I always liked the look of that buggy. I almost bought a used one for $750. There's a guy I see occasionally , when out riding, that has a 500cc polaris and Fox air shocks on all 4 corners.

It's my understanding that Joyner is rolling out a "lightened up" 250 model for '09. They did that with the 800 and 1100 already, with aluminum panels and a locking trunk on the wing. Managed to drop over 250 lbs. Now THAT would make the 250 rock!
I guess aluminum is a lot cheaper than an extra 150cc's, which would be a nice option for me. I like the heavy ride, but not how it effect the motor's output.

A couple of observations when watching the video of the machines jumping.
Because of the suspension utilized by the Joyner machines, the shock of the jump is absorbed for the most part.
The other machines will naturely show more altitude because of their design....stiffer suspensions and shorter shocks. So....I would say that "catching air" is not a true test of performance as the Joyner machines are designed to absorb the rough terrain.
There was a sprocket change in the design of the Joyner 250 from the 37 tooth on 07 to the 43 tooth in the 08s. Bob(eggy) tried to change that spocket before he sold that machine. He was not successful. Others have made the conversion to the larger sprocket and it made a marked difference in the performance level of the Joyner 250. What could only be achieved in low range in the 07s could now be done in high range with the larger sprocket.
