    I don't have a large area to run in so the low gearing was a experiment. I like the snap its got and I have to try a spittle for wheelies but it will do them everywhere. Looks like I need to tear the diff out and see what I broke. Then decide what to upgrade. I don't think I want to mess with...

    Ok so a hotter plug fires earlier and a cold later? How would one use that when adding more nitro. Example add 10% nitro add a shim or increase a plug heat range? Or both. Or is it remove a shim and change plug? Or is it leave stock plug stock shims and observe behavior. What do these act like...

    I pulled my 25 down to 3 shim it seems to have much more compression now. So how do shims nitro content and plugs change or work together in the 21 and 25? I'm looking at it like decking a jug or a tuning tool.

    My 25 has 5 shims and my 21 only 2. I had been running a OS medium 8 plug for several gallons. Then only could get McCoy 59 so that's what I got now. The 21 is in the truck now with that mc59 plug and 2 shims runs real good I think.

    Does the extra percent nitro make that much difference. Do I need to add or delete shims to run it?

    I understand the math of the gearing. I'm wondering if I will have a better bashing gear ratio. In my mind I think id get a better holeshot with just a little less top speed.

    Do you think it will change the top end much? It feels plenty fast with a stock bell and a 49.I only had a spare 52 so I started pulling motor to put it in. Someone told me a 21 Trans won't use the same spur as a 25 Trans. It seems to fit normal. My slipper clutch was toasted too. Melted into...

    I will try that. Removing shims change the trapped volume? Will that work with 20% nitro? I wonder if my 21 has 4 shims or 3

    Ok so I had a spare .21 engine laying around. So I pulled the 25 out and put it in. This 21 motor rips way better then my 25..... How is that possible? It needed tuned but still way better. I am now thinking of either getting my 25 repinched or getting another motor. I don't want to spend more...

    Ok guys got it really running sweet. First day I had that was about 60 out side. I popped the pivot off the throttle servo. Turned on my receiver and remote. Turned my throttle trim up to half way and put my arm back on. Now it opens fully and really rips good.
