Hey everyone, I have some questions about the potential of converting an 86' KZ1000P over into a drag bike. Most of my drag experience is at the San Antonio Speedway with my 80' Malibu, Concours 10, and Concours 14. How difficult would it be to build this bike into a low 10 to 10 flat quarter mile bike, while still being able to ride it home?

The budget is tight out of the gate starting at 3-4 grand, so will be re-using most of the chassis parts such as the swingarm and wheels. I will try to divide this up a bit to make it easier to answer questions.

Chassis
- Any issues with frame integrity? These frames look to be the most robust stock I've come across with plenty of cross bracing.
- Is there a slick or decent tire out there to fit the stock wheel?

Engine
- Plan is to weld up the crank, port match the heads, look into cost on larger valves
- Switch over from stock electronic ignition to Dyna Digital Components.
- Can the stock cams be re-used or is there not enough duration/lift?
- How big of a big bore kit is needed? Or will stock displacement fit the bill?
- Compression ratio to aim for to use pump gas? 10-11:1?
- Are the BS34 carbs capable or is it simply better to go with a new set of smoothbores/flatslides?
- Issues with cooling?

Transmission/Sprockets
- Longevity and strength?
- Upgrade the clutch basket, clutches, and springs?
- Are the stock police sprockets geared low enough for this application?

I'm sure I'm missing a few things, but trying to get the ground work laid on this build. I appreciate any input and advice on this.

The budget is a rough start. Got a few other avenues to work out.

McKinney look at my sig. for an idea of what it'll take to get in the low tens.
I'm not in the tens yet but getting close just a need a set of good cams, Ti spring retainer's. and H/D shim under buckets from APE
and a carb upgrade so other $1500 + on top of the $2000 or so I've spent just on the motor so far.

Then lets add all the other shit in off the top of my head.

Dyna 2000 ign. + programming kit. $500
Air shifter kit w/o kill box. $200
Digital Delay Elite rpm switch. $200
VM29's smokin deal from a buddy +
all the jets and other parts I've got for them. $300
Swing arm and wheel/brake setup w/tire, $500
Total $3700
With my labor @ $50. an hour added in I've got over $6000 in my little bike.

11's should not be that hard. My stock 78 KZ1000 did 12.20's all day long. I did have one occasion where I hit a 11.99 and followed it up with a 12.00. I thought about the 10 second street/race KZ, but I think the closer to 10 you get the more likely you will have other issues on the street.
