Just rebuilt my topend with a driveline 392 kit and wanted opinions on how it sounds initially. Sounds a bit rich at the air screw but other than that, crispy to my ears and it seems to rev out well in neutral. Haven’t ridden it yet so load may change that. Driveline suggested a 320-340 main for my elevation and yearly temp range. They were very specific with the needle clip position so i doubt that needs to be changed. The excessive smoke when revving is just from the assembly oil. Engine mod list: Driveline 392 Assassin topend (as cast), FMF Fatty pipes w/ T5 silencers, +4 timing, VF4 reeds, Chariot billet intake, Stock carbs (320 main, 30 pilot, Stock needle at 4th clip), Uni pod filters (one stage), a Noss trixx coolhead w/ 20cc big bore domes, and Sunoco 110 race gas with klotz benol @ 32:1 videos:
hey guys so I recently purchased an 02 banshee 392 cheetah cub 4 mil stroker. the guy I bought it from was kind of a knob and couldn't answer any of my questions. he had paperwork from vitos that the original owner gave him showing the 392 kit was bought along with some other stuff. it has a pro design coolhead with 22cc domes, some sort of aftermarket carbon fiber reeds, Toomey t6 pipes and silencers, k&n direct mount air filters with outerwears, vitos performance carb kit (whatever that includes) 340 main, 25 pilot, and some red needles that must be part of the carb kit. but on the paperwork I noticed it said the 392 kit was for a stock crankshaft. he said he had it rebuilt 8 months ago and the place that did it told him it was a 4 mil stroker. is there any easy way of finding out for sure if this is a stroker or just a big bore besides having to pull the cylinders off and measure a rod? I thought maybe I could pull the coolhead and see if it has stroker domes in it. if so what is the difference between regular domes and stroker domes? also I went trail riding with it last weekend it ran great but it was very dusty and towards the end of the day it started hesitating a little bit. I didn't think too much of it but it had me a little worried. well the next day it wouldn't start. I pulled off the air cleaners and the slides were loaded with dirt and gunk. I know the air filters were clamped on tight and I noticed the tors units on top of the carbs were loose and wobbling around. could this be where all my dirt came from? I pulled off the carbs and cleaned everything out, installed new float needles because one overflow was leaking since I got it, and made sure to tighten down the top caps so the tors were not loose anymore. well ever since I tightened them down it runs like crap wont idle and falls flat on its face if I try to ride it. I messed around with the adjustment on the tors and just ended up disconnecting all the electrical connections at the brain box and the thumb throttle and now it runs great??!!! I don't get it. so I ordered the tors eliminator kit that should be here this week so hopefully solves that problem. I also ordered a new chariot billet intake and billet reed cages and im wondering if I will need to change my jetting? seems like a pretty big main jet and kind of a small pilot??? any help is greatly appreciated as I used to own a built quadzilla and a big bore trx330r but im new to the twin screamers!!! thanks guys
