Hi Guys
Did the muffler mod, put in a K&N filter. plug is black now and bike is not running good, some times feels like theres no power, and after going at top speed let off the gas will back fire numerous times. Like I said only happens once and a while
The carb has a 150, picked up a 145. put the 145 in last night, turned the air fuel screw out 1/2 turn. the proper setting is two turns out? was this proper seems to run good but lacking top end?
AM I GOING IN THE RIGHT DIRECTION?

Yes but not allways, allso at times seems to not have power at any speed, I spoke to my dealer who is a good guy and he said it is to rich.
P.S how is the weather in BC I lived in Calgary for a while and played in the rockeys love the hills

When I rejetted I didnt touch the air screw, I had to jet up, should I do anything to the screw? I think I have to go down still though, it was backfiring yesterday after going fast then letting off the throttle. Anton by lacking top end what do you mean? Not very fast or no power?

I can get about 53 mph, does it backfire when you let off the throttle after going fast?

The weather isnt bad, last weekend was hot 18-21 or so, this week we are down to about 7-10 during the day, but mostly sunny. I am no carb expert but I would say you are still rich, I had to change mine 3 or 4 times to get it, but like I said I think I need to go down 1 more, I am backfiring quite a bit, but will look at my plug to see what it looks like. If you want a bit more power try the tranny trick also. I did it and it has more bottom end now, not a huge difference but it does make one.

I think your going in the right direction, but I don't know for sure. Maybe try asking in the performance and mods forum

Take the stock Snorkel off and run it, if it runs fine you can try to find a radiator hose to fit (I did) I'm running 142 jets with only a snorkel mod, runs great! Sounds like you may still be a little rich?
