I also tried the ninja carb. The carbs fit in both the intakerubbers, and the right carb fit the rubberhose coming from the airbox okay. The left hose is too small as I recall. I fitted a larger hose over the existing ones.

The ninja carbs is a bit shorter, but can fit.

I also experience more power, but the carb was old and worn, and I used a lot of time trying to dial it in. I basically changed a worn stock carb, for a worn nija carb....

In the end I bought a complete rebuildkit for my stock carb at ebay, and got the "lost" power back.

The stock carb works pretty okay, the problem seems to be old age any many kilometers on the secondhand ones still around.

I got a set of early ninja carbs 30mm ones. I also bought new carb to cylinder manifolds. I am starting with Jens jet sizes, 115 mains and 40 pilot. I will shim the needles with the two fiber spacers I have and bolt them on and see how they do compared to my jetted up stock carbs. If you have any advice Jens let me know. I am running air pods for filters. THUMPTHUMP

Jens, Getting ready to put the ninja carbs on. I live at the same altitude as you. I put in 115 mains , a 40 pilot . Do you remember what the air screws were set at? I am starting at 2 1/2. Did you raise the needles? The choke cable from my 86 xt will work fine. THUMPTHUMP.

I think I raised the needles 1mm, and leaned it a bit out from there. I think youre about right regarding the idle screws.

Somewhere in the progress I also had an intakeboot-leak, so cant recall the exact jtting after that was fixed...

Hi Jens, I am a newbie to posting...until now I have just been reading the infinite knowledge you guys post..

Are you still using the tail riser on the shock, like the one that you measured up with great detail in 2013???

Ps, I am a massive xt fan, mine is identical to xtrocks bike just a tad bit lower which I am looking to rectify...

Yeb, it's still mounted...
