Freestyle Krash 50 Cal Footrocket Kit

Oh, I'm sorry, my answer was not for your question. ha.

For those two middle b pipe manifold bolts you need a super skinny wrench. Go to the hardware store and buy a cheap one and grind it down. Yay, another fun thing right.

I had to drill and tap new holes on the bed plates for all 4 motor mounts. It's a mistake from Krash. Fyi

Their pre-drilled holes on the bed plates came nowhere near where the motor mounts needed to be for my setup. I put the motor in with the mounts attached to the motor but not bolted to the bed plates. I got the motor/midshaft aligned perfectly, then marked where the motor mounts needed to sit on the bed plates. Drilled/tapped new holes, then dropped the motor back in with the motor mounts attached to the bed plates. Took a while, but it worked.

Mine came with no holes drilled and tapped at all so my initial motor install when new was cake....cake covered in gravy

Yep. I have a custom ground down wrench in my toolbox for the factory b pipe manifold also

after having motor mount bolts, exhaust bolts and carb bolts come loose on my HX, I've used Loctite and haven't had any issues since. if you've never gotten a good sense of how much vibration these motors give off, even at around 3k rpms, try adjusting an allen head idle stop screw while the motor is running. I honestly don't see how any of these bolts stay in at all.
If you use the Loctite, will you be using the red or the blue?
I used blue, but also bought a small bottle of red. I'm just apprehensive to use the red, as I've heard the only way to really break the red loose is with heat.

l would be a concerned putting loctite on bolts and running in salt water from seeing where you live."Salt is Mother Nature's loctite" is what l was told years ago.Try using Red-N-Tacky on all exposed bolts and nuts.l have been doing this for quite a while,but do have to check them regularly and mostly run in fresh water.But will tell you that l have lost bolts because of using this grease but better than not being able to break something loose.

I was told to use locktite on engine mounts. I bought blue and red. Maybe I'll use blue on the engine mounts. I've never been in salt water, but I hope to change that.

I have a ton of video from yesterday, but today I got angry and gave up on the Krash to work on my SXR. Hopefully tomorrow, my last 'vacation' day I can to the ebox, tighten impeller, other bits and bobbules while I wait on parts.

 

[KawiKid]

Yes salt is mother natures loctite for sure, and I've had the worst of the worst, but it has ALWAYS only been difficult on the motor itself, such as head bolts, etc. I've learned A LOT being surrounded by salt water, and ever since I've started using XPS Bombardierlube on everything, I haven't had a problem.
And, I've had good luck using the blue loctite. On the HX I was chasing down a carb/fuel gremlin so I switched from an A/M west coast Venturi flame arrestor kit back to the stock air box setup, and before I started using the blue loctite, I'd have issues with the 6 Allen bolts backing out at times. Used the blue loctite and hadn't had a problem since... it's fairly easy to break free as well (when you're wrenching and WANTING to take them out)

So yea chix, good call on the blue.
Also, please upload the vid. I need some in flight entertainment tomorrow before the plane takes off!
You've got til 12:38 pm eastern time and not a minute later!

 

[chixwithtrix]

Psshh, you'll have to check out my SXR build thread for video. Uploaded one last night and working on another now.



About to go back in the garage and work on the Krash. Thinking I'll try to work on the ebox and line routing since other stuff is on hold due to waiting on parts.

Rule of thumb is always use blue on something you will want to remove one day... red is for bolts you never plan on taking out.

I would have rather retapped, but the mounts 'new' location was too close to the old holes. Wish they could ave just done it right the first freakin time.

 

[Pat Benatar]

Kinda hard to see, but the black lines are where the holes should have been. Pretty far off from the factory. Would've rather had them just not tap any holes so I didn't waste my time trying to get the motor to align properly on the old mount locations. It was that far off on all 4 mounts.

Wow, worse than mine, it was the LH plate that seemed to be cocked on mine.

This ski better freaking ride like I hope it will....then all this butthurt will go away. I took 4 days off and so far this is as far as I have made it.
Spent 18 hours worth of work to achieve sorta engine alignment, siliconed the pump/scupper area, installed screws into the pump shoe, installed and carbon fibered tank inserts, cleaned the bpipe manifold and engine gasket surfaces (realized I need helicoils for the new smaller bolts), turfed the waterbox and tank...and that is it.

Today I will probably try to see what isn't going to work on the trim setup.

Pat Benatar , wow that's not even close.. I agree, no holes would be better than wrong misleading holes. Just crazy how they can build and produce multiple hulls and not come across this anomaly or at least mention it to buyers, as this obviously isn't a one off occurance.

Chix, I feel your pain, patience is a virtue and you're doing it right instead of just rushing it thru and half-assignment it.
Every little minute you spend is progress.
In the end, I think it'll ride just as you're hoping.

When stuff like this happens, where bolts don't fit/line up, do you guys mention it to them?

 

[Jyzmbe]

I use red on bedplate bolts and mostly blue on everything else. If it's an XScream part definitely use red. Doesn't matter if it's trim, steering or pole bracket lol

i dont use locktite i just torque to spec. When my elbow clicks she tight enuf

I haven't yet for the most part if I can fix it because you generally have to wait a while for parts to be shipped from Thailand or Australia. Once I finish the build and ride the ski I will be doing a thorough review.

Back when I was being shipped the ski Chris said they put an engine in my hull to make sure everything was aligned properly.
Not sure what powerful strain of weed he was smoking when he told me that because the pump rubbed and the engine lined up straight as a plate of spaghetti.

 

[KawiKid]

I agree, there's no way a motor/pump setup was installed and aligned in that ski. The two skis that I've pulled engines out of and swapped, I've never had those issues. I guess that's the difference between mass produced assembly line products and aftermarket hulls.

Obviously there must've been issues in the early stages of rickter/rrp hulls, but for the most part, does anyone have similar issues with the RRP starter kits that you guys know of?
