Plug chop test results...

[Shuriken]

02 model. UNI air filter. OEM exhaust. 5700ft elevation. 150 main jets.

I have this color at idle, mid, and full.

Are we going for the light tan or the light gray?

I think you may get an improvement in operation with 147.5 Mikuni mains.

Funny you mention that. I put 147.5s in my 85 many years ago....

I have some 147.5s on the way. It will be nice to have 152.5, 150, and 147.5 to experiment with.

To me, that's not a bad color. I think you may find the 150's will be golden to your altitude...especially with OE exhaust. Is it a single UNI filter in the stock air box? If you had a Kerker system, I would definitely say you need to get into the 147.5 range.
