BUMPERS rhino.... evergoing build thread

I havent touched anything but the main and pilot jet and the a/f screw. Its close now I just need to get a few areas cleaned up alittle. From what I was told thats the only three things I needed to mess with. And im not to carb savy..

if pull the top of the carb off and move the c-clip up one notch on the needle it should lean it out just a tad.

I will get some once i get the tune better... right now it goes rich when i nail it (like enough to smoke alittle) then goes back in the 12ish range.. i need to lean it out a hair..

does the idle air screw richen it up the more turns out?

Bumpers, If your talking about a/f screw on the bottom of the carb it will richen it up as it's turned out. I 've just went through tuning my carb and it was a learn experience for me. Best advice I was told is dial in the main and work down to idle being the last adjustment. That's also what seem to work the best on my bike. I also was using James's a/f meter for the tuning.

I will look into this .. I havent had time yet but im goin to read over some threads and see what I can come up with

I read articles that said start with the idle and work up, read one that said first thing start with the needle jet. I finally went back and started all over with the main and worked down and thing fell into place. I spent a good day where I felt I wasn't making any headway, that's when I said chit and started all over with the main. Good luck, it was a great learn experience for me and I now feel comfortable with it. One thing about a carb, you can't really mess it up, you can always go back to step one and start over.

Yea I know what you mean on the main jet. Having that dialed in is key.. thats where you dont want to be lean or have issues. Ive got it pretty close I may step down to the next size and it should be spot on then I will fiddle with the idle and part throttle stuff and see if I can get it more stable. Right now at some points it dumps enough fuel where you can see a good puff of smoke but as soon as you get in the gas it leans up some and runs good. When I see the puffs of smoke the wideband is reading low 11s into the 10s. Its hard to see really but I know its goin way rich and I know at part throttle its gunna jump all over the place . But the little blips of the throttle is where it seems to richen up a lot

Think I found my tuning issue .. I had some trash in my gas tank and there was some stuck in the pickup tube. Got it out and hopfully I got all the rest out of the tank I couldnt see anymore with the limited amount of veiw. I will see tomorrow if thats the problem.

The afr was different just about every time I made a pass due to not picking up enough fuel I suppose.. you can only make so many wot passes by a church on a wendsday night so I will continue more tomorrow

all buttoned back up and ready to ride alittle still needs alittle tuning i think but i will get it down eventually... it just goes rich at part throttle blips.. like in the 10s and smoke rich but wot is 12.6-13 so we are good there and most of the driving stays in the 13s.. right now im running a 152.5 mikuni main and 50 pilot with 1.5 turns out on the a/f screw.






new special edition shifter and guage pod i made and sticker bombed


flimmys got me another light bar coming for the bumper then we should be set. its suppost to be here tomorrow

Thanks guys. Shes goin ou for her maiden voyage this weekend. Im ready to see how it does I havent got to ride it in foever

really looks sweet lets us know how she does

New engine is great.. once I get the jetting dialed in it will be sweet. I cant wait to see how it runs once the fuel is dialed in.. it has way more power than it ever did before even running wayyy rich.. oh and I broke the driverside inner rear cv within 20 minutes of unloading lol

she aint scared to get dirty... see if you can guess wich side the cv was snapped on:afro:

Drivers side lol Looks good!
