In advance, I apologize if this has already been discussed, I could not find an answer when I searched. I finally got my XTs fuel line straightened out. Radio in, new 7.2v battery, needles reset and new carb/manifold gasket. Started it with 1 pull, HS needle is set pretty good, revs up good...

I've got one for you guys. I was running my m/t yesterday and the motor just shut down. at first I thought the plug had given up because there were no odd sounds or anything. it just quick. anyway after checking it out I've got spark and the compression seems normal. it turns over smoothly and I...

Hey Guys, it's been awhile since I have used my XB. Just installed a new motor and new super bee kill switch. My issue is whenever I turn the buggy, it dies. It will idle forever. Now I have the killer bee plugged into ay splitter that then goes into the receiver. Is this not the correct...

I was driving today and was open almost full throttle. Then the engine died. Tried to start and the pull start will not spin. Feels like it is stuck. I didn't want to pull hard in case I might break something else. Does this mean the engine may be seized or is it just an issue with the pull...

Hey guys and gals. OK, so I purchased a MT Pro V3 recently, along with upgrades. One of the upgrades is a Flowsystem 36cc ported engine 38mm bore x 32mm stroke. My question is, what Carb to use, and why? I have seen ported race carbs, carbs with accelerator pumps etc.. Also, a bit confused by...

Is there any easy way to tell what engine brand and model came with my MT? Not sure if it is CY or Zenoah. Can't find my engine manual either. Such a hot mess...

Hi all. Was running my MT yesterday after putting a new spark plug, Hitec t/b servo, Hitec single steering servo, and Outerwear pre-filter. Ran it for about 10 mins. Shut it down and changed the t/b servo arm. Ran it for about five mins and then it would only move under super high engine RPMs...

Hello, Does anyone know if the XT engine has a magneto or coil? If so does this usually go bad at some point and where can I get a new one? thanks, City

Need some help from you guys. I've got a Rampage XT with about 6 tanks through it. The problem I'm having is that once I get it running i have to keep throttle applied in order to keep it running. It will run for about a minute or two and eventually die. Once it dies it will not fire back up...

I have been waiting on some parts to run my Mt but I start the truck easily each day just to keep it from sitting. Today I cleaned the truck and went to pull it but the pull cord will not pull to crank the engine. It's almost as if the engine has locked up. Any ideas?

HY or CY whats the difference ??

Serious about replacing engines in 3 redcat's I own. Has anyone done the swap? Has anyone been around this engine (DDM's part number BB28X)? I would buy the black with carb, no clutch (chrome :) ; I assume the drive line is strong enough to take this engine? I really don't know how much HP and...

wonder if this engine would fit in a rampage mt? video is crazy, guess you could get it to fit on a rampage since the rampage chassis is bigger then the baja right?

Ok so I recently got a redcat rally used and I'm trying to figure out the engine size so maybe you guys can help. From the factory it come with a 2 bolt 23cc or 28cc hy engine. The motor that I got with this car has a serial number starting with HY30****. I'm assuming this is a 30cc motor? I've...

Has anyone fitted the new cy46cc engine to their mt , or is it to big , just thought it might be a good way to get big power without too much tuning Any thoughts from the forum
