Sold the Burgman finally. Got what I wanted. Real smooth Craigslist deal. Buyer from Chicago. Drove 2 hours to Lafayette and I drove 1 hour, met at an iHop. HE invited us in for breakfast. Offered the cash before I asked.  I misplaced my camera until he was loaded and ready to leave. His uncle had a real cool trailer. The tail folds up onto the front of the table. Then you can stand it up on casters and roll it around the garage, tongue up. Low deck height. Nice tow vehicle.



Deposit to the treasury and free up space for next project. Yay!

Installed a 16t front sprocket in preps for the drags. Hope to get to the Dyno first, but I'm thinking we've got her tuned pretty close.

We turned 13.66 at 104mph last year. Would like to knock that down some. The fastest I've seen a stocker at was 13.99 at 99. And that was in CA which are faster tracks.

I want to see how fast a street able, quiet bike can go.

Glad you sold the Burgman, they are nice...handy too. Different experience in many ways from a conventional motorcycle but in many ways they are alike. The luggage/storage is very handy.

Good stuff with the ECTA things...

Any ideas for what is next?
Are you going to put a free flowing exhaust and do some intake enhancements?  More radical cam?
On PHaedrus of course...

I'll miss the Burgie, but I never rode it much. IT was my wife's bike while I rode the FJR. But she never rode unless I was riding, and those days are behind me now. 

Titling is almost done on 305 Scrambler I've been babysitting. Got a buyer for that too, then we'll really have some space in the shop.

Full schedule by my standards anyway. Another Dyno run to see if last jet changes were effective. A couple or more drag race nights. Then another trip to Ohio Mile end of September. I want to see what's the best we can get out of the original set-up. Quiet pipe, tame cam, comfortable seating.

May go to Kentucky KickDown Show in Louisville, early Sept.

Then we may swap out a pipe, upgrade the cam, put some drop bars on it, and see what's up, next year.

+1000!! Why put a muzzle on a badass bike!

[MCRider]

I've got a bunch of pics, noticing the recent posts lack color. But Photobucket has not been cooperating. I'll get them when I can.

Scheduled for Dyno tomorrow AM. Just called them to confirm we're still on.

Since the last pull, I fattened up the main jets a tad, 122.5 to 125. And a bit more on the pilots, I forget the numbers.

Also spent some much needed time on the ignition timing. (running TEC point plate and HondaMan transistors) Suffering from a major brain fart, I couldn't get the point gap right. I was setting it on the "T". Finally resorted to the manual which told me to set it at the highest point of the advance cam. That did it. Set the points at 14thou. set the plate with a static light and it timed up perfect of the "F"s. All the adjustment slots were practically at their midpoints. Hooked up the old Penske strobe light ca 1974, touched the throttle and it went to the advance marks, smooth, solid, right on.

During this, I had pulled the Hitachi advancer and compared it to the other 3 spares I have. I have 1 that has "300" on it, a TEC. I used it instead of one of the Hitachi units. It had tighter springs, which is deemed good, and an obviously larger body with the flyweight stoppers in a different place. Don't know if those characteristics are of any value.

Don't know if its just me, but it really seems to start, idle, and rev better. Here's hoping for some good Dyno numbers.

Then its off to the drags for fun, and the Kentucky KickDown for show.      

[mrbreeze]

I'm sure you are keeping notes on all of your adjustments and parts Ron. It really sucks that you can't ride anymore but look at all the tuning experience you are getting. You could open shop for bike tuning if you were so inclined one day. A good tune up guy is invaluable. Good luck with your run and hope you see some good numbers.

[MCRider]

Dyno: Results v June 3: HP +1.5 to 2.5 depending on which chart you want to look at. Roughly the same rpm, about 8100. But it keeps pulling at that level to about 9200.

Torque +4.18 and the peak rpm dropped from 6900 to 6100.

I'm happy. It is much hotter and higher humidity today than before, but I think the dyno compensates for that?

AFR went where I wanted, a little richer. So I could lean it out a tad. But I think I'll leave it alone for cooling purposes.

Thanks! It really sounds good. Just a wall between the dyno and me. When he's WOT, it just screams, in a quiet sort of way. And not a whiff of smoke.

Yes, the dyno will compensate for temperature, humidity, and barometric pressure; this is the correction factor. 4.18 ft/lbs @ 6100 RPM = 4.8549 HP at that point! Did you get a print-out combining both the old and new runs? I'm inclined to think that the increases were more due to timing changes than the motor loosening up.

Is the correction factor done by the dyno or does the operator have to do something?  The Dyno does sit in a room inside a semi large warehouse, so it has a bit of a natural climate control.

Yes the printout had the June run with todays run overlaid.

Just read about the timing...my bad. i know my friends 929, which we dynoed through 3 stages of development, got stronger by 3 HP on a 4th pull a year later not changing a thing. That's a Honda engine for you.

[scottly]

Mike, I've seen spreads of an HP or three between three consecutive runs, with only 1 minute between each run.
Ron, the dyno stores the atmospheric data automatically when the run is made. The operator can view and print the graph, selecting from a list of correction factors: None, which will display the graph in terms of raw power, STD, which is what your operator used the last time, SAE, which is what I use, DIN, which is a European standard, and JIS, the Japanese standard. The SAE uses something like 60 degrees, 0 % humidity, and a barometer of 30(or is it 29?) as the baseline. In those conditions, the SAE CF will be 1.00, or the same as None. As the temperature increases, or the barometer decreases, the various correction factors will add a percentage to the raw power. In your previous dyno visit, the CF was 1.04. Because I live at 4500', and my dyno barometer typically reads around 25.5", my correction factors are more in the 1.15-1.17 range.

Me too. The oil gets thinner as the heat builds....that's what I figure when you get to 3 or more runs.

[MCRider]

I'm trying to use the "attachment" feature, lets see....

Well that works, you'll have to right click and rotate them.

The first one is a comparison with last June run. The squiggly red line is yesterday's run. He said he was having trouble with one of his connectors.

The second one is a comparison of 2 different speeds. Not sure what that proves. The tech probably explained it to me, and I didn't follow.

I like the top HP of 79.8. Slightly more HP and torque on the way up curve. I'm just glad I didn't back track after the timing and rejetting.

Pre dyno compression check. A little low by my standards   


Loaded for dyno. I can't help duplicate posts, I just love the look. On the way to VJMC Springmill a few weeks ago, on the interstate, a semi passed us on the right and blew his horn. I thought I'd done something wrong, but my wife was looking up through her window. The driver was giving us a big thumbsup. Almost as good as a trophy.

Thanks to HondaMan for helping me get the timing right.

It's on the high performance/racing board. Did you get a print of the torque with MPH?
