Do you add power jets to your carbs ( I run TM 32 with power jets) ?

I'm reading that thread, about 100 pages(1) Lots of info. Hadn't thought about the tubes, I'm on page 30 of the thread so I haven't read about its advantages or noticeable gains in power if any-
Also reading about base gaskets, cylinder raising and other new developments-seems like the guys in Europe have been experimenting quite a bit.

I've lived with my jetting for a while and it's been sort of rich, but the extreme heat and humidity the last few days really made a difference. Plus I had to do a complete teardown to clean everything. I do suspect my needles and needle jets are worn after years of use. I ordered 6DH3 and 6DH2s, also helping my friend with his H2 with TM34s

I'll see how these needles perform, then I'll get some 0-2s or something in the range and see how it goes.

Now I'm off to time my Z1. Same year, '74 :D

Thanks again

Nice setup with the VM38's Chris. Do the carbs clear the crankcase without issues? And how is the performance?

I got P-2 needle jets, 6DH3 and 6DH2 needles.
My P-6 10 year old needle jets were definitely gone-
P-2s fixed the problem but with the 6DH2s on groove 2 from the top is way lean
Now to decide if I go with H3 on middle groove or back to my original 6F 5 in the middle groove
But my original needles might be worn out too so I think I'll start with H3 in the middle-
Thnx

Took some time with Hurricane Irma and everything else to get back to my jetting. I didn't like the other needles and ended up using my 6F5 needles with the P2 jets. I settled on groove #4, raising the needle 1 notch from center. My original setup with P6 jets ran on groove #2 so now I'm at an excellent range. Maybe I should have got P4s but I'm OK with this-

I ran TM34's for years and spent considerable time and money getting them jetted properly. When I bought them I was told by the distributor that they flow a lot of fuel. He was correct. I ended up at O-0, 6DH2 in the 4th clip, 42.5 pilots 190 mains no air jet. I like the 6DH3 needle much better but it was too rich in the mid range. Ideally if the made N series needle jets I believe a N-6 and 6DH3 would be the perfect combo. I have since gone to VM38's. Results have been good so far. Here is a picture of the silicone tubes. I bought mine from silicone intakes. They were $16.99 each. 60 degree bends.


What are the carb mounts? Mikuni part#?

Thanks,

They are modified Harley Davidson compensator boots. Don't buy aftermarket as they are not as good as HD. Two fronts and one rear or 2 rears and one front.
