Updated as of yesterday. Put on two led pods and painted my bumper that got smacked up. Also got new-to-me front tires on rims with more offset, and threw on my nice tires for now as well as bleached and scrubbed the plastics to clean them up a bit

considering a plug chop the next nice day i have here in NY

I'm thinking it's the jetting being too rich but i want to make sure before i kind of disregard it for now. whenever i start up the quad from cold, let it idle and warm up, and go to take it down the block, WOT it will almost fell like it makes no power and is choking up until about 3rd gear and...

alright cool i have been emailing you and dabbling with the decision and i think I'm going to send the head over either today or tomorrow. thanks for helping the decision lol

well i already have a fmf header and pipe, vforce4 reeds KN intake and ram air mod to the airbox, and jetting but that according to this post doesn't really add power, but i just picked up a head to be rechambered into the hemi head style but before i ship it out and go through with it I'm...

poking the old thread back to life, anyone get anywhere with this? I'm also interested in real or close to real potential numbers before i start spending money on machining and this and that and time pulling the quad apart in the cold garage.

After some snow :D

alright so now i know to not let it run the carb out a little lol i figured it was just running off compression and high heat but i wasn't sure

Alright so the other day I was riding in the snow we had. Finished riding and put the quad away and I shut the fuel off but let the motor keep running so there wasn't a lot of fuel sitting in the carb. Pulled the choke out to half so it wouldn't run lean and let it run. After about 30 seconds...

How do I go about rechambering the head? I saw the video on the porting and I'll send away for that when I can but I keep seeing rechambering the head to a hemi head with no direction how to do so

Also a side note, which is a better higher flow filter? A K&N or a uni flo foam filter?

Well i already have the vforce 4 reeds full FMF gold exhaust K&N filter, as well as a ram air mod to the airbox (just removed the upward scoop on the box) and bumped up the jets so everything aside from motor mods are pretty much top of the game. Just wanted to determine if the big bore was...

Okay so I'm planning for my next rebuild and I'm considering the Vito's racing 240cc kit. I found this for $200 more which includes the 240cc kit and a 3mm stroker. I'm curious to know which would yield more of a gain in power since I don't have a case splitter aside from a flat head screwdriver...

What brand compression tester? I used a harbor freight compression tester and got 70 so I rebuilt the top end with all new piston and rings gaskets tightened everything nice broke it in and only got 85. So I know the tester was inaccurate

So I'd do a top and bottom end break it in right and then not worry about it. No matter what now that something blew up in it your better off doing the motor over than doing one part at a time. Sorry you bought a beaten blaster idk what to tell you ┐(‘～` )┌
