tuning

[tospreeornottospree]

so on the 3rd almost 4th tank its tuning time general zod has a i believe a 62 low jet and a 158 hi jet tried to do a plug chop today and the plug still was white switched to a 165 still the same..... i dunno if i did right searched for a procedures and seems like im on spot yet it seem like the jets are too big
set up as following 44.4mm mini stroker crank 50mm bore kit compression was around 138 last time i checked 28mm oko carb and a v8 pipe any better starting points would be nice! temps run pretty good buzzing around but wot with the 158 temps would slowly rise never let them get out of control but any feed back would be nice!

to do a plug chop you have to go WOT for a few minutes and then immediately shut the engine off and come to a COMPLETE stop, because the engine will still turn over creating compression, sucking fuel into the jug, thus making your plug chop useless

exactly what i did!

did you stop right away or did you roll for a while?

BTW there was an off throttle temp spike to 450 today after going 67mph

What is the highest temps a CHT should read before I should worry?

[tospreeornottospree]

basically rate after the the house nest the the shop and killed it hammered on the brakes till it slowed down enough where the clutch disengaged then finished rolling its kinda hard running at that speed to stop on a dime maybe 100ft or less of rolling

Sound right to me.

hahaha that CHT should read as high as 400 if you're getting higher, you gotta richin up a little

whoa! a bit fast wouldnt you say pry shouldnt do that too many times... cht is delayed and is transfered heat so might be more heat there then what registers

Are you killing the ignition with the "run/stop" switch or are you letting the engine run until you get the clutch to disengage? If you are not killing the ignition you are wiping the plug reading. FYI, if the plug does not color inside of 1 minute at WOT, it is never gonna color.

check for intake and exhaust leak.make sure you retighten the all the bolts for the cylinder ,exhaust and intake too.

why would a plug never colour up if it hasnt after a 1min wot run? if this is so how do you do plug chops if the plug aint going to colour up do you get a new plug

I think what bear is trying to say is that it does not take longer than that.
