125-200cc One year anniversary for the 165!

That is really good especially when you factor in the use of used cylinders. Mine has been great . I had some pinging that would not jet out, but a little race gas mixed in fixed it right up.

Congratulations Walt and all the 165 owners out there. I have NEVER seen a grassroots effort like this to improve a bike. And it is so successfull!! I've heard nothing but praise for the kit and it's performance. Also and more importantly IMO I've heard nothing but praise for Walt, his dedication, and his integrity. Cheers walt!

There is definately a kit in my near future. And if the HGS is better than the PC on top-end and peak HP, that will be my ticket!! Please, do tell, Blake!!

The only issue with the hgs pipe is the P-3 guard that I had for another pipe doesn't fit as well as I hoped. It won't bother me a lot but it looks bad.

I just got back in from running the ktm 200 cdi versus the husky CR cdi, everything else the same the CR ignition pulled 3mph more on top. You can't really feel any difference other than very top pull but the speedo doesn't lie. I will leave the ktm dual map ignition on it for all to try.

I was in the same boat. 100 LL Avgas did the trick. The thicker base gasket did not eliminate all the pinging. I'll experiment with mixing 100 LL with pump premium, but if that doesn't work, the straight avgas really isn't that expensive ($6/gal), and there's an airport just a few miles from my house. It also has some other advantages: no added ethanol, and it has added stabilizers for a long shelf life.

I'm really intrigued by the 165, I think it would be a hoot on Rocky Mountain singletrack...
What is the pipe/combo for max torque for us <ahem> more mature riders?

Definitely the FMF Fatty for the 200 SX converted to fit. That is my personal choice for riding exactly the same thing you are riding. The HGS pipe works great and really helps the upper mid to top but I just don't spend a lot of time there and the fatty still runs good there it just flattens out on top(SHIFT).

Walt,
The 165 is a marvel.... plain and simple!

Norm summed it up succinctly, a marvel!
Thanks Walt

I just got my next 2013 WR165 from Hall's Cycles. Now to finish prepping it for competition.

Hello everyone,

I'm thinking of buying a 125 in the near future..
The only thing i dont really like about a 125 that you have to rev it that high all the time.. actually i cant talk about it with certainty because i didn' t rode one yet, but i can say i do like a bit of torque.

But now i red a few topics about the 165 kit im getting extemely curious, so when i decide to buy a 125 how can i get my hands on a 165 kit considering the fact that i live in the Netherlands..

Congrats Vinduro .

Just send Kelly at Motosportz an e-mail. Several kits overseas at this time.

Is the kit done as a core-exchange deal, or do you send a cylinder and get the same one back in 165 guise?
