SkullDuggery, Compression Retest

[SpecOps13]

In the original check of my 89, months ago. The cylinders measured 220-230 (My 94 was 150-160). I've been looking for a second gauge set up to do a retest of comparison. I found one yesterday with the proper 12 mm adapter. Although the resulting numbers are somewhat lower than my original readings, they're still high, over what a stock motor would read.

I did the readings multiple times and with a variation for those who don't know about it. Throttle closed and throttle open during the readings will make a big difference. You want to do the readings with the throttle wide open.

Cylinders:------ Throttle Closed------ Throttle Open

RF:--------------------143----------------- 200
RR:--------------------142------------------195
LR:--------------------142------------------194
LF:--------------------140------------------192

The differences in reading from my original numbers is likely caused by differences in the 2 gauges. All readings are close, showing that my motors internals are in good shape.. I'm a Happy Camper with these numbers no matter what they actually would be if I had a perfect gauge.:clapping:

Still sounds like some head work has been done. I read about your Dyno run. Great numbers, I still wonder the extent of PO Mods in your motor.

what did it dyno

 

[SpecOps13]

126.02 rwhp / 83.63 tq

Nice numbers. 4% variation is good. I bet you're happy!

Those are good numbers for a Stage 7 & Kerker 4-1 , w/o any additional motor mods.

No stage 7, just a modified stock set up for now..

It'll eat my buddy Earl's FZ1 for Breakfast, Lunch and Supper, so I'm Very Happy...:clapping:BTW, Earl is a very good rider too...

Hey SpecOps13, Good run for my orange 06. Was fun that day

I'd like to know the history of that motor. Is the valve train a little noisier than your '94?

 

[SpecOps13]

spider13, Great Day we had... But now you've got me way out classed...
Sell the 06 yet????? I keep pushing guys on buying it....

355cid: Very much noisier than the 94.... It's still a mystery motor....
The power curve appears same as stock though so it may just be higher
compression.

not yet Kyle is helping me with it.

If anyone can sell it, It's Kyle... He has a Golden Touch...

When I put my 1260 together, I sent the cams out to WEB-CAMS and went with their #227 grind. When I got it running the top end is quite a bit noisier than stock. I went over my clearances twice so I guess thats just the nature of the beast. I've got about 450 mi. on the motor now and it hasn't gotten any noisier. I still might pull the valve covers and check clearances again at 500 mi. just to be sure, as that will be the end of my break in period and I can start running it harder. I wouldn't be surprised if your '89 has had similar work.

 

[SpecOps13]

That would be Awesome. With Kyle's new motor, I need all the extra ponies I can get.
Even then, considering how good he is at the strip, I'll likely be of little consequence to him...:sad2:

Good Luck with your motor, hope it's "Sick" with tons of power....

Gotta go work on the 94's carbs. Later Bros...
