Before dropping it in, I need to make sure that everything is for sure.

power increase
 

just assuming 13.5 cc's per hp for the GZ. You could expect 7 or 8 more hp. Sounds good. If you do not mind. What did your mechanic charge?

The message you responded to:

....was left 5 months ago.

The author seems to have disappeared.
He talked a good story but seldom produced any results.
I can't help but wonder if he ever really had a bike at all.
:roll:

Easy, you got confoozed again. Jordan joined 5 months ago. He posted his most recent thing, the one about making sure that everything is for sure, on july 5th. The date under someone's name (on the left) is their join date. The date at the very top of the post is the day/time it was posted. So in actuality, it was less than a month ago last time he posted.

But jordan, easy has a point, we want results! Some of us would really love a mod like this if it worked!

I can certainly appreciate Jordan's enthusiasm for wanting to make the bike faster. However, if you've read the rest of this topic, it's no secret that I don't think it's possible.

Honestly, for his sake, I hope he hasn't already spent the money on a kit (which he says he already has but no one has seen pictures of it) that can't be used.

He was once a pretty active member who seemed to fall off the horse around the same time that this mod should have been completed.

:oops: Ya got me! :cry:

Neither the first time nor the last! :roll:

I think he dissapeared. maybe his conversion didn't work out.

Of course it didn't. We tried telling the guy.

I think it would be easier to shoehorn a bigger motor on the GZ250 frame than try to make a big bore kit from scratch, but then unless you got the bike for free or have way too much free time to kill, it would make more sense to just buy a bigger bike. Maybe Jordan figured this out.

As was mentioned before, $500-$1000 for 3-8 HP isn't really worth it.
