bored 1 over, added head wi/21cc domes, v-forces

[knight_ripper]

Ok, I have a 97 shee at sea level.....running great. But I was down to 90 PSI per cyl. So it was time to redo the top. I however had to have her bored to 1 over. And since I had the top end off, I purchased a NOSS head with 21cc domes, and V-force reeds.

 

My question is.....will I have to re-jet her?

 

I have never been good with carbs so the last time I had her tuned by the stealer. So, Im not sure whats in her carbs now. But I want to see whats the general concensous....SINCE I DONT WANT TO RUN HER LEAN....ya know?

 

thanks for the help.

 

 

 

Tors removed, exposed K&N with T5's.

 

Just added the NOSS head with 21cc, and V-Forces.

 

Im still runnin stock carbs....but that will soon change!

Well, in theory, your mods shouldn't change too much, but with any modification to the motor, including overboring 1 size, you will need to take it easy through break-in and check your plugs. Obviously, after a fresh top end, you can't go right out and run a WOT test, but fire it up and run around, after you've checked your "after top end" compression, and check your plugs to make sure they're plenty colored. Once break-in is complete, go ahead and do a wot jet check and make sure your jetting still matches your setup, you might have a little variance and then you may not have any. Regardless, it shouldn't be much at all, if anything.

Thanks Red,

 

Thats what I was thinking....I thought the 1 over might do something...but wasnt sure. I will be putting her together tonight and will do a compression test at that time. Then tomorrow I will take her out and warm her up. Fingers crossed...cause this was my first top end.

 

I gotta go get the plug chop instructions....time to use um.

 

oh and Im already familiar with a top end break-in....so thanks for the heads up. No WOT for 5 minutes....lol. Ok a whole tank should suffice. How am I sapposed to not WOT her for a whole tank. Thats gonna be tough.

 

but will have to be done.

 

Thanks again,

 

 

PS....I also added a Kevlar clutch, springs, and a trial tech computer....finally I can see how fast Im going.

 

Shee should be rockin now.

Let me know how you like that Trailtech, I've been thinking about getting one.

 

As far as the plug chop, I wouldn't even worry about cutting your plugs until your able to get into it full throttle, just make sure there's some good color on them after about 20 minutes or so.

 

Good luck and you can come and do mine next if your feelin froggy.
