Somebody is gonna have to get some action shots on here at some point. The last time we went riding I guess we were having too much fun cause we didn't take any.

I think the oil made for it works best. It is real sticky and a quart will last forever. However, in a pinch just about any oil will do, on 2-strokes I ran the same oil as in my pre-mix, and sometimes even motor oil.

Did you notice the extra large rear fenders on the blade? Those would come in real handy.

It is possible to send your carb out and get it machined, or you can pick up a 28mm motorcycle carb (I think stock blasters are also this size) for cheap and probably squeeze it in the rubber intake. If you don't really want to mess with the stock cables etc., milling it out is an option.

 

Yeah, true. It was just nice to know that I had a carb that was working so nicely on a nearly identical GY-6 powerplant. Others would be trial and error... and it is possible to get too much carburetion too... bleh. I'll just keep asking around and see if 24mm is still the norm. Who knows, maybe one of the carts out there has a larger carb bore.

We'll see what an updated ignition gets us soon, hopefully.

I was thinking of taking some on-board video in the near future... maybe get some shots too.

Allright, I don't know what I was thinking, I forgot these type carbs have a butterfly in the front so machining them out would probably not be an option unless they make a corrosponding larger butterfly.

All this talk about carbs did get me interested enough to pull mine off and put a spacer to raise the needle. I couldn't tell much difference but I only raised it a little. I (now) remember on a harley I had it had the same type of carb. The carb kit I purchased for it had a new lighter spring to go on top of the slide so that it would raise faster. I don't know if that would be a benefit or not but it is something to think about.

ALSO, the rubber boot on these seem to have a sharp angle as it goes into the head. The all metal one on the xtv may be a smoother transition, and also since it points the carb higher, that would seem to indicate less of angle which may help to increase airflow.

 

Well, the carburetor on my KPX does have the Keihin symbol on it. So it appears to be a keihin as well. There has to be a larger version of this carb out there somewhere.

Finally got around to shimming the main needle today and I definately have improved mid and high range. The increased power is very noticeable when climbing a hill.

Also added lights down low on the XTV to give better night driving ability. Just picked up some $20 driving lights from WalMart and used conduit hangers for mounts on the tube frame. Worked out really well. Definately a good deal brighter now.

 

Just got an idea. Did you try the XTV carb/intake with or without the plastic spacer in place? The intake/carb might fit if you remove the 1/4" spacer off the head.

 

All it would do is drop it 1/4 inch which would not be nearly enough. It was dead center pointing at the cross bar. We need a different angle to either drop it way low (sharper angle), or raise higher (less angle).

There has to be an manifold tube out there that would fit...

 

Some of the kids quads I have seen have the intake either 90 degrees from normal or completely turned around backwards. These are usually on smaller displacement but I bet the bolt pattern would fit. They look roughly the same size in diameter.

 

Do you recall which models they were? A good distributor might be able to help us with dimensions. Or heck, I'd go to the nearest dealer and see if I thought it would work.

check that auction out. Now if we could just find one that comes w/ 12.5 hp output like some of them, swap them out... sell the 10hp model that came with the cart. All set. [img]i/expressions/face-icon-small-smile.gif[/img] Instant 25% power upgrade... and no engine teardown.

 

Stu from Blade e-mailed me back confirming his new carbs are 24mm as well. I'm sure that's the norm. He also stated that he asked the techs to look into 28mm to see if it improved anything for them. He said that could take a while, but at least it puts the idea in their heads. Pretty cool to have a responsive guy that has contact with the techs developing these things.


I sent him another question asking if he knows what the standard jet size is now.
