the kwik shift

[tmac20031]

Have any of you heard about the kwik shift mod and does it really work? If any one has some good info please feel free to share.

new to me. never heard of it but hears what I found on it.

"Kwik Shift" Kit

The Kwik Shift kit makes hard shifting and missed shifts a thing of the past. By interrupting the ignition pulse for a split second, our kit allows faster and more accurate shifting without letting off the throttle or pulling the clutch! After all, when the clutch is in, you are not making time. Our kits are custom engineered for your application and require only minimal wiring experience. Also includes a bypass switch for normal operation. We also designed this low profile kit to

hmm ne one gonna take the plunge lol

Once again...my advice is that there's alot of other go-fast parts that you could do that will give you a hell of alot more advantage in a race. You've got pipes and reeds for christ's sake! If you had every go-fast part available and you were looking for that extra edge then yes, I'd say the kwik shift is a good purchase. But right now? You'd be better off w/ a timing plate, mill the head, air filter, etc...

Sounds like alot of money to make your Banshee shift easier. I would get ahold of Boonman or have Us do some shift mods to make your bike shift like a dream for MUCH less! Usually around $25.00

jefss mods work real well and are much cheaper, I had the FAST shift mod in my bike before I went to an over ride, I had to switch it back to stock cause the damn thing shifted to easy. everytime ya hit a bump with the override it changed gears.

hows that for easy shifting

This sounds more like full throttle shifting, like the pro drag bikes run. There are kits just like these being used in street bike drag racing, same advantage as an air shifter. If dragging is a huge part of your riding, and you have the other mods done for more power, I say go for it.

Again, I have t6s and I dont see the need for me to spend more money on different ones, so Im trying to find other ways to help my bike so that it isnt fighting itself mechanically.

Advance the timing, get a coolhead, run race gas. Do that and you'll get 20x more gain than you would with just a kwik shift.

I guess I could get a ricky stator timing plate. Im not exactly sure how it works but I imagine that advancing the time between spark ignitions has to go along with using the race gas(higher octane=greater force=advanced timeing requirement).Am I right or am I way off. If I happen to be right, thanks for the advice. Is the coolhead for reinforcement? Can damage occur to my bike if I switch from premium to race gas on and off, changing the timeing accordingly?Thanks

[Wallrat]

No ur not right. Basically ur altering how early the spark is generated before heading to the plugs. Too much and you risk detonation, so you need to run race gas if you go too far. The only benefit race gas gives you is the ability to run higher timing and more compression.

 

Too much compression and ur also gonna risk detonation because pressure=temperature. I dunno that I'd recommend anything smaller than 20cc domes without getting ur crank trued and welded.

I ran across this thread a while back when I was looking for options to modify the shifting on my banshee. My bike is already modified (porting, timing, pipes, carbs, etc

[csrmel]

why cant one just add a contact switch to the shift lever so when you push down or pull up on the shiter it engages the switch which would be connected to the killswitch part of the wiring harness.

csrmel,

 

I asked myself the same question when I was looking around. The answer is yes, you can put a contact switch in. One big problem though - the time it takes to shift still depends on how fast you pull the lever. While your foot is on the down travel, you're bike hasn't engaged yet.

 

I asked Brandon at mull engineering why I couldn't just put a switch in and you know what he said?? They've already tried it. It failed in 8 minutes of riding at the dunes. It clogged with sand. I guess they mean it when they say they test everything themselves he said they've actually timed a few riders that shift extremely fast (these are pro riders) and they shift at approx 70ms. But when you count the down stroke of the shift lever this increases to over 2x. That means a pro rider would probably slow down if they used a switch!

 

Mull engineering says you can shift in about .035 seconds. The reason is that their system kills the bike for only a certain amount of time, that you preset. It also allows you to finely tune the point when the bike cuts out so that your bike only cuts out for a very short time. You can hold the shift lever in the up position all day long and the bike turns back on in .035 seconds. If your foot is a little slower you can make the time longer. I think the fastest setting is for people that are insanely fast though. I'm not quite that fast.

 

They use a sensor system that's just stupid simple to install and has no moving parts. I was so worried that i would take this thing to the dunes and it would fall apart, but there is no moving parts. The way they tell you to route the wires is pretty cool too. You really can't tell you have it installed.

While i'm actually on the computer tonight I might add another thing.. Since i'm new to this forum and have no idea where else to post i'll post here. not to plug for Mull Engineering, but if anyone else has jetting or other engine problems, Brandon is the man. I had a problem with my bike running fine at WFO, but had almost no mid range. I also had a few other small problmes. Anyway.. brandon knew exactly what i was talking about and had no problem telling me how to fix it. I figured he'd tell me to just send it to him, but he told me over the phone what jets to use, and even checked with his engineers for my little suspension "bump steer" problem. Brandon has obviously been around banshees for awhile and knows a ton about them.
