125-200cc I Rode The Prototype Wr200 And It Is Amazing...

It's great that your cylinder cleaned up so well.

MY WB165 kit landed safely todayand will beinstalling this week on a 09WR125 ,I will be modding 2 different pipes and will share my results with everyone.
Thanks Walter and Kelly
Dave

My WB165 arrived yesterday as well. Now I just need my carb back from RB designs who are closed for the week

Has anyone tried the FMF 125 pipe?

Ordering Thursday or Friday.....So excited!

YOU SHOULD BE

Dave, which pipes are you going to try?

Couldnt wait till thursday or friday....ordered today!

It is amazing. When the jetting is spot on, you have to be careful in the tight woods as the wheel will come up in 1st-3rd, sometimes when you're not expecting it... tagged a tree pretty good because of this, not complaining!

My ktm 200 has more power for sure and will run out better, but not down low, which was surprising.

I'm having a custom pipe made for the 165 from RPM in upstate NY. Should be interesting...

Your as bad as me! The day Walt told me about this kit I placed my order and had my cylinder on it way to his shop! You wont be disappointed! Let us know what you think when you ride it. And I dare you to wipe the grin off your face every time your ripping it up!

erigre let me know how the pipe works out please and congrats on your WB165.

Will do. Heading out on the road for three weeks friday. Pipe should be here when I get home.

No word on Dynoport making a specific 165 pipe?

All these 165's somebody should step up and who knows it may be better for all the guys that have 144/150's too.

Doma's work real good

Just a little update on my quest for the perfect race bike (I feel I am close). For some reason I never rode my WB165 with the FMF WR 125 Fatty that it came with. I was so power hungry when I received the WB165 top end that I immediately modified the Gnarly and threw it on. Well I swapped out the pipes this evening after reading posts and questions from other members. I am still running the small silver with the OEM power valve springs. My knee is still killing me and I am still out of work so I probably shouldnt be riding at all. I threw on a helmet anyway and went for a quick easy ride around the back yard for the sake of you Cafe Husky members! You can thank me later! Poor me had to ride! I was surprised how ridable the 125 pipe was. It didnt have near the low end and mid of the Gnarly but then again it didnt have the massive hit either! I would ride or race with this pipe if it was my only option. I am currently on Walts KTM 200SX Fatty waiting list so if it is like the delivery of this pipe but only more bottom and mid I am guaranteed to be happy! I noticed that the 125 pipe did rev out more as well where the Gnarly signs off pretty early. I am interested as to what switching power valve spring combos will do? If the pipe didnt hang so low I would consider racing it at the next event. The Gnarly tucks in so nice that I will probably deal with the extra almost to aggressive hit for the next south Jersey sand race. If I dont have the KTM 200SX Fatty for the race in West Virginia (mid April) then I might just run the WR125 Fatty. Just remember that I race both south Jersey sand and north Jersey / Pennsylvania rock and roots. My back yard area / testing area is rock and roots as well. If I raced strictly sand and faster events with minimal rocks and roots then the Gnarly wouldnt be too bad at all besides the fact that it doesnt rev to high. I am not a revver and stick to low and mid as much as possible. I cant wait to try the modified KTM Fatty!

Thanks ! I have a FMF Fatty and PC 2 on my Husky and will run that until somebody comes up with a plated one for the 165. What can I say I'm old and slow so I gotta at least look good. My 165 will be here soon and I'll be testing on a MX track and woods loop .
