Zoöid Third Times a Charm CB175

is this correct? We want to compare the aftermarket lift to the stock lift of the 175 which is .244 or .9173" that is in the manual. Most aftermarket race proven springs for the 160/170 are giving lift pressures at .354 - .40" lift. For example the KPMI is 123lbs@.354". So if we divide the 123 by .354 and multiply it by .244" we would end up with the equivalent lift pressure which is 84.77lbs @.244" lift for the KPMI valve springs.

The stock 175 is 98.54lbs at .244" lift. We confirmed that the 175 stock spring is 100#@.275" lift.

If that is correct the KPMI has less pressure than the stock 175 leaving us with other questions. Is valve float mainly caused by resonance? Is KPMI springs making an assumption that the max rpm for the 175 will remain the stock rpm? Why in the heck would we buy KPMI springs to replace the stock springs? (The resonance data for the KPMI springs is not available.)

my math formula was wrong once again I didn't account for preload for the Kpmi spring when I took 123/.354*.244. The correct formula is

123-47=76
76 / .354 * .244 =52.38

Add the pre load 47 plus 52.38= 99.38 for the Kpmi which is the roughly the same as what we got for the stock spring nose pressure at .275" lift.

My wife is getting real world examples to tell her math students...lol.

Beehive springs are generally lower rated as there is very little chance of spring surge.
Saying that, 70psi open seems way too low?
Run them at close to coil bind full open height (about 0.010" instead of 0.040"between coils)

Is that how you got your name Crazypj?

Nope, but it is motorcycle related

(from about 40+ yrs ago)

Hey guys, i knows its a while back, but on that case weld attempt, you didn't mention heating the part up to wick that oil out after the vapor blast. Not guaranteed, but it'll increase the success chances if ya torch it good, immediately degrease, and torch it again to pull the degreaser out. Its amazing how much oil will hang on inside a fissure. If the case is gonna be junk anyways if it wont seal, grind a trench in there too to expose some fresh meat, then zip it up.

Sorry guys I haven't been around I have had some health related issues I have been sorting out since this summer. My atria was stuck WOT turning 20k . Was always being drug back to the pits. They put in access ports next to my superchargers and reflashed my ECU, no porting or polishing needed. Atria and ventricles have the correct timing. No need for new electronic ignition. They scoped my tank and found massive polyps of rust. Checking to see if the tank can be salvaged with Metal rescue or if they need to do more extensive rust removal. My supercharges aren't providing enough boost because my computer is restricting boost. I just thought I was tired because we were raising Zeke. Luctor et emergo.

Glad you are on the mend Patrick, I am having some similar issues and your comments on PPI's, which I also take are giving me the right questions to ask my DR. when I go see him in a couple of weeks.

maritime I have 15-20 polyps in my stomach and it is rare to have them unless you have been on long term PPI's which apparently my former doctor didn't know. I thought I was having a heart attack when they yanked my chain. Two of them were removed about 40mm long. I would find the cause of the Reflux. Like the little bikes the answer may be counterintuitive like adding acid. The esophagus is suppose to button up when the stomach has the correct amount of acid. So adding apple cider vinegar may be the smart choice. I switched to Turmeric and cayenne and was able to go of PPI's for 4 months. As Teazer says "it is an optimization exercise" as with life and bikes. Good luck!

Thanks, I saw the scope pics on FB. I Take the PPI because of a Schackies ring, which is caused by excess acid hardening the last ring in the esophagus, I never had heartburn but one day stopped being able to swallow. They fix it by breaking the hardened ring with a stretcher and you get 3-5 years before it hardens up again, the last time I had it done 5-6 years ago the specialist put me on Tecta (PPI) and I just had another scope and the ring is still flexible. After reading the side effects of the PPI's though I think I will wean off and just get the throat stretch done a little more often. The hip fractures listed make me wonder if I wasn't taking the PPI's for 5 years would the deer have broken my hip off so easily and would the leg being crushed not have been so severe? I know the PPI's have not been on the market for very long and so these issues are just starting to come out. What amount of Turmeric do you take each day? I eat that in food but would take it as a suppliment as well.

Back to the build. We got to modifying and polishing up the the cerianis. Zeke lines out the shop work with his sharpie.

We had some issues with the carbs interfering with the shocks so we ordered some flatsides with a spigot end. Took some measurements and found some cb350/400 intakes that can be modified to fit the Cb200 or cb175 head.
