Rk tek 858 kit not working.. Det 7 code

[Jkinzer]

i shipped three kits up yesterday with tungsten washers (assuming their for you three? Sea to Sky Motorsports) you should have them in 2-4 days. Been working willy PolarisBlue the last couple days over the phone and the clutching got him on the right track now he's ironing out a PCV map for his.

These sleds need more than clutching and fueling they need true tuning capabilities. A way to control heat, timing, fueling on and off throttle, and load change. Clutching is the icing on the cake. not a motor tuning senerio. You will need to find the tuning issue separate then clutch to the motor. If not you are only masking the problem and not getting the full potential of the motor.

Yes Jkinzer those 3 kits are for us... Thanks a lot.

How much for the Vi-pec? $2g+? The real question is is there enough seat of the pants gain to justify the $1600 more over a piggy back fuel system.

It it better performance with day in day out riding. Not alot of days lost riding with the problems you are facing.
To most that is seat of the pants performance.

Nice sales pitch Brycter, but when these sleds are clutched properly from the start there are no days lost riding with problems, and to answer his question NO the Vipec does not make a $1600 difference unless money is no object. Having a dealer that knows what he's doing and sets up your sled properly makes all the difference in the world. All of the 858's up here that have been set up and clutched from day 1 are yet to have a hiccup.

 

[brycter]

I guess that is why people buy the vipec.

Because the ones I have done all have this problem and have tried clutch up and clutching down. Like I said before your clutching is just masking the true tune of the sled.

It about ve and you motor is not flowing correctly with a stock ecu and piggy back. Can you get close sure but not spot on. That is a fact.

Timing, fuel, trimming in the right areas is what is needed. You just can't do that. Clutch all you want but you don't have the right info.

Sales pitch maybe. But proof is in the pudding.

I know it definitely not for everyone, but my Vipec 858 has been running like a champ all season. The data logging alone is worth the admission fee, and I highly recommend Bryce for his tuning abilities.

Glad she is working good for you.

I Like I said before your clutching is just masking the true tune of the sled.

Serious question - If the sled performs better(track speed, back-shift, etc.) with the altered clutching & the detonation is eliminated how can you say that the problem was masked unless you were able to do a side by side comparison of your engine re-tuning VS Kinzer's re-clutching?

At this point without a valid side by side comparison of your method VS his on the hill, I'd say that both of you could be accused of masking the problem.

No offense intended, just an objective observation.

Well got all the new clutching parts installed and 70 grams of weight now, going to the coq today to try it out... Hope shes fixed and no det 7. Will let you guys know at end of day cross your fingers kelsey or im sending sled to you, and you pay freight lol.

 

[zx7thrills]

Still getting det 7 code

Yup with all the new clutching and have 70 grams of weight still going into det 7 code I can not believe it . geting rmps up to 7500 and shes hiting det 7. I just have no idea now what to do except trying to sell it. If anyone in bc wants a 2013 pro 500 km electric start with Kelsys Big Bore 858 kit that keeps hitting det 7 code ill sell for 8000 bucks, just want it gone i dont have the patients to deal with it anymore and if no one buys it go on u tube type in Kelsys big bore kit there will be a video of it blowing up at the coqahalla parking lot.... ps my pals sled to with big bore just ran terrible too today he going take 2 grams out though trying 68 grams ....

 

[xc6rider]

Have you tried blending any race fuel, or avgas?

What's compression on all the sleds, tested with same gauge/process etc...?

What head were you supposed to get? Maybe kelsey accidentally sent you a higher compression head?

Can't remember if you tried any of this or not.

 

[zx7thrills]

I talked to my dealership today thats trying to fix sled and thats what they said maybe Kelsey mixed mine up, dealership said we should try race gas and see if it runs better plus there going to check fuel pressure. One last try with it than its gone either way.. Was told with this kit you just basically bolt on thats it. my seasons basically been ruined because of this

 

[Sunvang]

How much for the kit and bd box? No clutching needed.

 

[zx7thrills]

Wont sell separate , sled goes with kit for 8k or sled goes up in flames, Kelsey I think mentioned fixing it also to Mc kay marine so its one of those 3 things...

 

[rmscustom]

Did you ever check the squish on all 3 to see if its different?

I got another idea too. Instead of taking a huge lose on the sled get ahold of Brycter or vice versa. If the vi-pec makes the sled run awesome and better than your two buds you pay him for it, if not send it back no charge and either way you report your results on here...
It would be a great way to prove the worth of the vi-pec with 2 others running piggybacks that you know and I'm assuming you ride with all the time.

I can definitely feel your frustration, my 858 ended up with fried pistons after just a few short runs. The map supplied with these kits are not nearly rich enough for scandinavian sealevel conditions. But blame is on me for not checkin my plugs quickly enough, and not beeing experienced enough reading my af values.

As mentioned before, have you checked squish, tried running more octane, change out electronic components like ecu, sensors, injectors, ves solenoids etc?

If this sled was closer I would have been all over it for for 8k, but I think you should give it some more time.

 

[zx7thrills]

Thanks guys for last 2 comments, What is the squish?? How do I check that? Just soooooooo frustrating as I am not very mechanically inclined , we were told just bolt on new kit thats it... Never again I like pull and go! But I have been told when this kit is running proper it really is a big difference . Sorry to hear about your pistons Rydningen... How do you like you 858 now with new pistons etc?

 

[rydningen]

To measure squish you use Three thin pieces of soldering wire and braid them together, then you take Two pieces of the braided wire and put them into the plug hole. Each of the pieces should be Places of the wrist pin on top of the piston, this should be done With the piston allmost at the top of the bore, Then you rotate the engine so that the piston squishes the solder between the head squish band(the Outer face of the head) and the piston. Then you take out the solder and measure the thickness of the area that has been pushed together, normally measured in the middle of squish band.

This setting should be approx .065" at sealevel and about .055" at 5000ft. This might be different With Kelseys kit, check With him.

If the Readings are less than this you should add another base gasket between the shim and cylinder to achieve proper tolerance.

Heres several videos on youtube explaining basics of the process.

Your dealer should be able to do this if you do not feel confident doing it yourself, they should also check the compression ratio of Your head at the same time.

Well, I am currently running Stock cyls With a stage Three kit, Kelsey wont have pistons in a couple of months, so I Guess ill just have to be patient!
