So cool to see stuff done right in someones garage somewhere, so many people that just throw shit together, keep on buddy ! I just bought a 2020 rancher 420 on Wednesday and I’ve watched all your videos, about to do your PVC lift !

I know this was years ago.....but all I did to mine was put the 300ex jet and bowl on my 300 frtrx carb....works just fine. Gives it just a little more pep.

Question when the throttle cable screws into the carb is it ideal to seal where it screws in ?

Thanks for the video man really helps out, what brand aftermarket carb did you use? Don't wanna end up getting some garbage carb that'll never tune right

This is an OEM Honda carburetor I would never put an aftermarket carb about anything I own

@twintwo1429 2 жыл бұрын

@@MudPuppyOffroad there are plenty of OEM spec carburetors and rebuild kits that are aftermarket and much less expensive. Like anything else, it just takes homework.

Man I have a Honda 300 it’s snorkeled tight I have greese the spark plug I feel like I have done everything but sometimes when it’s under water it will bog down like it’s giving out of gas I’ll pull it out and it will crank right back up please get back with me and give me your thoughts

I'd try a new coil/plug wire. Or wrap it in electrical tape

Which TRX are you referring to The old school 350 or a rancher... I would not recommend a rancher it's not much of an upgrade

@MudPuppyOffroad 3 жыл бұрын

The old school 350 doesn't have an excavator pump so it's not great either

@chrislayton4025 3 жыл бұрын

I was talking about the rancher, okay so the 400 is the way to go. I’ve found some OEM 300 carbs but $300

300ex jet and bowl will fit on the 300 frtrx.....no need for all the extra work unless you want the 300ex carb on your four wheeler....but just the jet and bowl swap does give it a little more power.
