Glad to hear you're getting the 105 sorted out...  Nothing like setting up a bike to suit your riding style.   :)

So although I hardly rode this year (extended vacation, lot's to do around a house) I still got a good feel for how this bike is going to work for me. A few times at the club property I rode with guys I didn't know, good woods riders, and I smoked them all on the 105  ;D They were embarrassed, you could tell. So I took my wife to the track, ran laps on the Husky, then the 105, and in the woods I'm significantly faster on the 105. So I just have to decide at this point if I want to keep this one (It's a high hour bike I got cheap) or look for a newer, cleaner one. Would be nice to have one of the new Husky TC's, but they're a little out of my price comfort level right now.

At least I have a project for the winter, that's the main thing

I'm sure that both are good, but the carb is not your problem.

I was thinking about this yesterday. I watched with great interest as the smart carb discussion accidentally kick started a Lectron discussion and people started buying them (and not smart carbs) in droves. The Lectron became the darling carb on Cafe Husky (and elsewhere), people singing their praises and boasting that the days of constantly jetting were over. Then came the custom metering rods, and the threads on which rod to use, how to set it up,  how to make the bike stop doing this and that - and lightly used Lectrons for sale. I found the whole thing really interesting on several fronts.

Anyway, if you're fouling plugs with the new oil at 60-1, you have either a jetting problem or low compression. The Husky bike that I ride is notorious for difficult jetting and many mistakenly swap the TMX out for a PWK or Lectron. The real problem is that they have very low compression, especially with the 144 factory big bore. So I increased my compression and fixed the squish. Now (still with the TMX) I have no spooge and crisp power from top to bottom.

thanks beaner...  The old girl's got plenty of compression...  The running joke in my riding circle for those asking to take a ride on the 380 is, If you can kick start it, you can ride it.  It takes a strong kick to turn over the motor...

So something to keep in mind: Less oil (leaner) = more fuel going through the jets (richer.)  Going from 43:1 to 64:1 is going to make your jetting richer across the board and potentially lead to fouled plugs if it was borderline rich to start with.

You are correct sir...  I think I need to go one notch leaner on the needle...  I'm also going to pick up some new jets one size up and one size lower so I can get her back to where I'm happy with the jetting....

This past weekend I fouled a plug...  1st time in many, many years...  Now most of the day I was riding behind my son's 5 year old as we escorted him to and from a safe riding area.  But when I fouled the plug, I was hauling arse through the woods... I've been running Amsoil Dominator for quite a long time...  but recently my supplier retired, and I've not found it locally.  After some extensive research, I've decided to switch to Bel-Ray MC-1. 

Since the switch I've not been happy with the bikes jetting...  I now have a rich bog at 1/2 to throttle, more smoke than I'm happy with.  I've always been running 3 ounce's to a gallon (43:1)  The BellRay seems to be much thicker, and doesn't want to mix like the Amsoil.  After trying the 43:1 mixture I went to 2 ounces to a gallon (64:1).  The bike seemed to respond better, but fouled a plug...  So I am officially on the hunt to two things...  A new Amsoil dealer, and I'll be seriously looking at the Lectron & Smart Carb as a future upgrade.

as you are aware , or maybe you aren't, i have never track ridden a fourstroke. I tried one 250f  ten years or so ago in a pasture and immediately decided they weren't for me. Now, i have gone back to the era of bikes i started racing in and couldn't be happier, the response i get when i bring the bikes to the tracks is interesting, i have never had so many track workers and riders wave me around a course before. lots of thumps up as riders pass, lots of curios on lookers, not even on my modern 2's have people been excited to see these particular era of bikes. oh and when the 500 hundreds come out, forget about it.
