Redcat GY200

The poor 'new' front tire.

Better view of the 'mixture' screw.

From my Jeep 'get home bag'.

Coated intake, till I get a new one.

Pulled the carb out and dismantled it. Looked like the Amazon in there. I reused most of the parts, replaced the ones I had new parts for. It now runs great and will idle. Still needs an intake, it backfires sometimes. Good power. Seal All is only temporary, on backfires it blows bubbles at the cracks.

Shifting can be 'catchy'. They told me they changed the oil, but I'll change it again and use Welds recommendation.

Jeez I hate that thing. Mine is impossible to get at when the bike is running because I have to squeeze my hand over a hot exhaust.

Is that a wasp nest in the cylinder fins?

I ground a large 20d nail into a custom stubby screwdriver and slipped ribbed fuel line onto. You are right though hard as heck to get to. I have found that 1 1/4 turns out from full in has worked great on the last three carbs I rebuilt.

I think there was 7 generations of wasp nests in the cylinder, I think thats a good indicator of how many years it sat.

Thanks again for the diagram.

FYI; this thing is TALL! 34-1/2" The seat is much higher than the 200GY-2. 31-1/2"

Yep. (And I thought the Chinese were supposed to be short).

I cut 2" out of the front springs and am considering a shorter rear shock. (About $45 on local ebay).

The spring cut is easy if its the cheap type of front springs like I have. Just unscrew the top caps, pull out the spring and cut off what you want. (The spring is quite long, about 24" from memory). Allow about 1/3 for compression, so if you want a 2" drop cut off about 3". Theres no real risk in cutting the spring. You can always put a spacer or the old piece of spring back in to restore original height. (A spacer will give you a slightly stiffer front end which is often not a bad thing anyway.)

Thanks for the info! The seat is also wide, making the inseam even taller.
I have no clue why they built a bike for 6'3" and taller, it's almost easier to mount a horse lol.

Congratulations on your new acquisition! Only 48.2 miles on the odometer.

Thanks Spud.
I cleaned it up, coated the intake again. Runs great, like new. Had to straighten the front rim. Adjust the over tightened chain. Pleased as punch on such a good deal. Lots of vibration. I will retighten all bolts and loctite as required. I will also install new cylinder fin anti vibration spacers. In comparison to the 200GY-2, it vibrates quite a bit. The 200GY-2 is smoother, more refined. The Redcat seems to have more power, then again it's new. It is certainly geared low. I can take off in 3rd with no problem. Sprocket time.

[SpudRider]

The Zong is geared entirely too high from the factory. If you are riding off road with the Zong, you need to drop 2 teeth on the counter shaft sprocket. In contrast, the Redcat is geared very low from the factory. The lower gearing gives the Redcat more torque, and makes you think it has more power.

[oviking99]

Thanks again Spud. I agree, lower gearing higher torque. The stock 200GY2 being geared more to a mid-range 'cruiser' and the Redcat to more of a tractor.

I've found that aluminum bars cut down on vibration a bit, as do decent grips. If it's still too much, try a pair of Mechanix M-Pact gloves; I recently saw them at Walmart.
