Well I would trust Eric on that one, so that comes back to the carb. Did the Dyno that you were using have a sniffer on it so that you could tell us what the A/F ration was?

 

and if you can post the dyno runs so we can help you a little with A/F if you have them

 

I will scan them tomorrow and post them

 

Ok guys, I just posted my dyno results in my pics. The first results are from June 2006 when I had the 730 kit in and no head work. The test was done at Rexburg Motorsports in St. Anthoneys. I believe the attitude is about 4500 feet. I used a bald set of knobbies for the dyno. I got the best results with a #100 power jet installed.

The 2nd set of results are from September 2007 after I had the porting done and bigger valves installed. Everything else was the same (tires and dyno). Had the best results with the #100 power jet installed again. As you can see the power was down though to a peak of 46 compared to 52 before the head work.

I just posted the pics - may take a minute to show up.

Thanks for all you help guys !!!

 

That minute is sure long. Or is it just me that can't get the pictures to show?

Not just you, I have not been able to view them as of yet either.

 

seat of pants did the ported head and bigger valves make a difference???

 

I just sent the mods another email. I re-posted them this morning and nothing has shown up yet.

Ds650powe: The seat of the pants differance was worse then before the head porting. I did change a rear sprocket before trying the bike with the head porting. I went from a 42 on the rear to a 41 for clearance issues. When I am ridding in St. A's I usually launch in 2nd gear, the bike would do it no problem before the head porting but fell on its face after.

 

Ok Guys

Could not figure out how to get the dyno charts in my profile so the mods ahad a suggestion from an old post. So these links below should take you to the Graphs.

Thanks for waiting guys.
