I have the FMF Fatty for the new 150 and it definitely doesn't kill the top. I pulled it off the TC150 to install on the new TE150. Typical Fatty response with nice bottom, good mid, and ripping, never ending top end.
Your TMXX sounds like it will be as close to perfect as it can get. If I didn't need something to transition 5-6K' in elevation almost every ride, I would stick with the stock carb and sort it out. I also like the mileage bump of the Lectron. I just don't have the time or inclination to spend time jetting when it will just be off a half hour into the ride.
The new FC250 is very fast. If it is a push in acceleration with that then it is really humping for a 144....That is my experience too. Very much a rocket ship of a small bore that still runs amazingly well on the bottom/mid.
Love your work and keep sorting and posting. I look forward to where you end up on your suspension settings. I don't have your speed so might not need the bottoming resistance you want.
Thanx for imput Walt. From you and Norms Recommendations, I will go fatty then.
My honest opinion is: I don't think the fork or shock going to need revalved.
I have to wait lil longer till the boinkers break in. If anything, I will go up front and back one spring size.
I was gripping front wise pretty darn good yesterday and not richoting off all the roots rocks and etc....
I tried every thing possible to push it. I did bottom couple times hard both front and rear but went two clicks up. Now I'm not bottoming and staying about an inch up.
In the manual, I set preload dial at 3 on both forks. One issue, in order to go beyond 3, the fork bleeders will have to be removed. Some not thought that one out?
I also set everything on sport both ends -12 clicks. Front/back is then + 2 clicks compression only.
I like the rebound the way it is.
The back tire is no good! Wearing fast and knobs are spaced too far. It effects my braking and excellaration in corners.
I cannot believe that knobs are rounded off already.
Norm, what Golden Tyre are you running for your terrain? Mine is similar.
Definately will go fatty 216aa.
I will post video shortly of how fast I got this bike running. You can tell it's hauling arse way above stock!
I wanted to come out of that corner faster but it was muddy and I'd end up on me arse!
Camera man was lil shaky cause the skeeters were biting him all over! That tire kinda scary went it breaks grip.
I knew it as soon as the carb went on

!
Also, keep in mind that with all meeeee gear on, I'm probably 205 to 210 lbs and 6 foot tall.
Just imagine a guy on my bike at 175-180?
