so what egt temps are you getting at wot?

[sanjuro]

750-760F, and then it spikes to 800 if I do it for 20 seconds.

[bakaracer]

Not bad! now just need to dail in the trans somemore and fine tune that carb for the summer ride.don't forget to write down your settings for the time of the season that way it makes it easy to change when the time comes.

[sanjuro]

I couldn't have gotten to this point without your immense amount of guidance.

I'm ready to start building the 2nd motor.

[bakaracer]

Your welcome.I just hate to see guys blow up there engines from not knowing what really caused it so I figure I share my experience from years of messing with these things.

Went for a ride today and the carb slipped out of the rubber boot between it and the intake.

This is my second bike where I've used a TM24 and Stage6 rubber boot, and in both instances the carb eventually worked it's way free. It's irritating and not really confidence inspiring. I'm wondering if the Dellorta carb setup by Malossi has a more secure connection.

After looking at the carb today I noticed a gas/oil mixture mess near the starter motor, and decided to take the exhaust off. The gasket doesn't fill the exhaust opening on the cylinder head too well, so I'll be making my own gasket out of some gasket paper from AutoZone tonight.

In the meantime, I decided to test fit the Burial exhaust. Think I'm done with the PG Typhoon after seeing this below:

Very Very nice!

oh man that thing looks crazy!is it going to hit the side skirt when you compress the rear suspension?

[sanjuro]

My shock is really beefy and fairly stiff, so it doesn't compress that much.

[bakaracer]

Did you ride it yet with the new pipe on?

[sanjuro]

I was planning on it, but a lot of things got in the way today. I have to go out and get a drill bit that will go through the metal so I can finish getting the EGT probe installed. Apparently, my drill bits were too weak to go through the header wall.

Also, I went to the O'Reilly's and picked up some paper gasket material. I'll use that in conjunction with a crush gasket to seal the exhaust from leaks at the exhaust opening on the cylinder.

[bakaracer]

get the mr.gasket exhaust gasket paper.its the thick white sheet.its around $11 and can make about 18 gaskets out of it.I use that and it works awesome.

[sanjuro]

That's exactly what I bought, and it was $9 for the entire 1 foot square sheet.

[bakaracer]

even better.i think with that pipe you might have to down jet because the header pipe is smaller than the v8.but maybe not
