Installing a 90's Katana head on a GS1100

[LarryT]

i did the same thing to the ignition plate on my turbo dragbike

[LarryT]

on my turbo street bike i used a dyna 2000 . it has a retard built in . i wired it to retard when starting and then retards at 4lbs boost

Yeap, pull the seat and you can see it.

[RacingJake]

This is a much nicer setup IMO. I like how you moved the MSD to the side. I take it that the tank sits under the seat? Your track may not care, but its good safety to keep it in the frame rails anyway.

It was not that long ago and there was no retard. If you decide to go with retard, good luck. The cost was one thing, then try and find room for it.

Not so strange that the fixed advancers are normally marked at 28 and 34.

It's amazing what you can do with a few feet of fuel hose and some self tapping screws.

I've had all my msd stuff for so long I bet it cost twice as much now days to buy it.

Looks good. You have more room than I figured you would. Battery must be slung in the belly?

Are you just going to fill it off your car tank?

When you start using the nitrous, you want to make it very easy to change the tank out. I know how you like to hot lap that bike.

You may want to stick something between the tank and the engine to try and block some of the heat if it becomes a problem.

Did you make sure your NOS tank number was outside the recall? Why do we have to outsource to Mexico anyways???

Where you at Jake? What's going on? Ray.

I made it out to the track tonight and only had a few issues to take care of.

After the first easy launch, no slick or wheelie bars bike ran good up until the return road. Started missing like it was out of fuel after a few more bad runs I pulled the plugs and 3 out of the 4 had no gap. Seems like those dome pistons and small chamber head was adjusting my sparkplug gap on each run. I'm using a .020 base gasket and was hoping that would solve it but no. So I cut off some of the ground lead until the plug would fire to the side of the plug instead of just down. A OK now.

Also had one of the valve cover bolts come loose and boy did the oil started to flow on top of the cover.

Never did any full throttle runs or even used the air shifter, but the engine sounded mean, turn the throttle spin the tire, best tonight was 7.71 at 94 mph. The bike never wheelie, it just spin the tire so I'll be trying a soft shinko next.

Bike has alot more in it, I like the results so far.

Also this head can go up to 12.5K redline don't now it the GS bottom end would like that so I was trying to shift at 9.8K. Didn't even want to try the nitrous.

Congrats on the good first result. Can't wait to hear how it runs once you get the NOS in the equation too. :twisted:

[RacingJake]

I can't wait either for the nos

Pulled the valve cover off and did my one time inspection of the valves keepers, cam sprocket bolts and cam caps. Looked good and re-torque everything, even the head nuts too.

I'm going to check on some race plugs next.

Whats funny is now I'm foot shifting so that means I got to pull my feet up on the pegs now as before I just used the back ones.

Boy did the price of race fuel go up??

[80GS1000]

Are you using rearsets or the stock pegs? Were your toes touching the ground or something?

[RacingJake]

When I bolt my wheelie bars on I also have some pegs there too. So when I push the bike forward doing staging and when I launch they just seem to find the rear pegs with out much action from me and I hit the air shifter button.

But now with no wheelie bar, no rear pegs and no air shifter I got to bring them forward. It's just a mental thing I got to get use too again.

Box and bars make racing alot easier, all you got to do is train your left thumb to do all the work.

[lecroy]

Did you make it into the 6's?

[RacingJake]

Only a 7.71 at 94 mph, my 170 tire was so hard it felt like I was driving on ice. I hear those shinko 003's are real soft and at $119 I may just get one.

I was thinking today of just putting the slick back on the rim. I'm also thinking of removing the lockup for awhile to get alittle more feedback from the clutch.

I did install a 2nd crush washer on all the plugs today so hopefully that issue is fix.

[lecroy]

There must be a story there because my stock 1100 runs 7.20s - 7.40s. That's with the hard Battle Axe tires. I run about 15 PSI in them at the track and it's hit and miss if it will hook up. You must be spinning like a 70s fueler bike.

Still, not bad for the first run of the year with all the changes you made.

Just missed a gsxr head on ebay. Not saying I want to run one just thought I would get one to tinker with.
