The rear is a Firestone ANS, the front is a Dunlop K70.   I suppose they're both like a on/off road tire.   This will only see pavement....I went solely for the looks.  :D


So where did you get those tires?  Liking them since you've been riding them for a while?

Front is from motorcyclesuperstore, rear is from DCC.  From my limited experience, they ride really nice.  Fairly grippy, and plenty smooth too. Not something you want to be throwing into the curves at WOT, but fine for daily cruising.

Hey, on your GN, there should be 2 plugs coming from your magneto and a couple wires...and then there's a random red or pink wire with a female connector on it, where does it plug in on your bike?

Not sure.   I'd love to help you, but my harness is all loomed and taped up.

So I've been trying and trying to get a VM36 working on my GN400 and I'm all the way down to a 15 pilot and it's still too rich. I gave up haha.

With your stock carburetor, and a pod filter/open exhaust, what jetting are you using? My stock carburetor jetting is causing my bike to shoot flames out the exhaust and all kind of cool shit. I want to get my jetting right lol

Stock pilot jet, but I went up from the 132.5 stock main to a 142.  It runs fantastic, but it does pop quite a bit on deceleration, with the occasional nice blue flame too.  Plug looks good...so its mostly the tiny muffler.  If I put the stock can back on its really quiet with no popping/flames.

With your stock 132.5 did your bike pop and backfire like crazy when revving it? That's what mine is doing right now with a pod filter and open exhaust. I'm thinking I need a bigger main jet, or to put a washer or two under the needle.

EDIT: I just tried a 142 main and it is still backfiring and throwing fireballs out the exhaust lol

Yes, it still does it.  :D  I'm going to start upping the pilot a little to see if I can reduce it some, but I'm not too concerned with it.  As of right now my plug looks good and the bike pulls hard through all the gears.
