I rolled my 97XX out of the basement into the 10 degree air and light snow this morning. This was my first attempt at start since my first round of mods and maitenance.

Pulled the carbs, 45 pilots, raised the stock needles 1mm, enlarged the vacume hole to 7/64s, set the pilot screws to 2.5 turns out.

Changed the plugs, installed a K&N filter and change the oil.

I hit the starter with no choke, 1 2 3 seconds, nothing. Full choke, 1 2 3....Fire! Runs well but starts to cough, so I backed off on the choke and it smooths right out.

I start to blip the gas after it warms up for a while and it seems to respond very well. As the temp gauge rises, I start to wack it open and closed as fast as I can. The RPM jumps to 7K and back to idle with just the slightest stumble on the way up.

The trottle response seems a little crisper than before. I know I must ride it to really tell if things are improved, but can you tell anything by nailing the throttle in the center stand?

The roads are a mess. It may be a while before I can road test.

I also added 6mm to my rear shock mount. I pulled the rear shock to increase the preload to the max. I am going to order the HyperPro front fork spring kit.

I received my new rear Diablo and will send in for the free front.

So far so good. I like working on the bike, hope it works even better on the street this spring, thanks to many here for the help, Steve

:twisted: You won't be able to tell how your jetting is in 10 deg. weather. If you really wan't to know how it is before spring take it to Mike's Cycle in Menasha. They have a dyno with an exhast sniffer. One pass and they can tell you were you have to richen or lean it out. I did this with my 97 Bird and the jetting is right on the money. :twisted:

Steve, I feel your pain, I was outside in 20 degree weather today syncing my carbs. After I was done and put the bike together I thought about trying to go up my snow covered driveway but got over it. :cry:

I hate winter :!: :evil:

As far as your rapping the throttle, yes it will tell you a lot. It's doing what it should, revs riseing smooth and hard.

At 10 degrees, keep in mind that it is running lean. So with the slight hesitation now it will be fine at 60 degrees. :cool:
