Blaster 96 WaveBlaster 1 (Redemption)

[mrfist9]

About maybe... 2 rides into my latest iteration of my last B1. (Blursed) I determined that I had once again not built what I wanted. So like any ADHD ridden rider. For sale she want, sold she go.

I hadn't given up, basically every other B1 I ever ridden I absolutely adored. All that said, I wasn't really feinding for one, but kept my eyes out for a good deal. Specifically want a 96 twin carb. I have to date not had a dual 38 ski, wanted to see what it was all about.

Found my self Saturday morning Superjet shopping frankly cause I just need another b-pipe, stumbled upon this. Drove to Destin Sunday.






Figured worst case, I get a 61x/62t, sell the chamber, make it stock and send it on it's way.

Turns out it's super clean, rides amazing, and ah man I LOVE the thing. Doesn't really get me a loose bpipe (original goal) now does it.... IDIOT. Did nothing, put a whole tank through it, airbox flew off. Minor setbacks.







So now what. sigh another ski project just what we needed.

Gonna try and keep it simple. it's stock as a rock + a bpipe, really nothing crazy I've found so far.
Only things are a @JetManiac waterbox & a RIVA rear outlet. Which is nice.

Problems:
- weird idle transition... and idle. gonna go through carbs, got some fresh kits on the way, plans to jet it to FPP settings, hope it's already there with just a leaky N/S or something stupid.
- wear ring / impeller gap, gonna inspect and shim see what that gets me. Looks clean enough, but cavitates a bit when you do something stupid on it.
- fuel selectors bypassed.. normally I do this but on this I want a selector for SURE

Things I've already triaged
- tank check valve was blown out, replaced with a new
- missing small waterbox strap
- airbox flew off (2 of the 6 carb mounting holes are stripped lame)
- head pipe bolts 1 backed out, other 2 were loose as hell. All mismatched hardware. And ones helicoiled to M8
- steering shaft is tight, got it better but this won't matter

Mods planned:
- UMI (no particular reason why just a want)
- Bars probably
- Advance the stator a tiny bit (if it isn't already)
- play with nozzles & impellers
- intake grate maybe
- shaved head (wish this was easier to procure)
- reeds (if I find metal ones still)

Just want the thing to work! And work well!
Stoked regardless

I don't recall seeing a b pipe that looked like that in a blaster before. Nice looking ski regardless.

Thats the blaster limited chamber. The mod chamber is the center bleed chamber

 

[mrfist9]

Got the UMI in
way more of a pain than I was bargaining for on an afternoon job, oh well. Still kinda tight, guess a cables in my future.
Didn't have any grommets on hand, future me problem. Also probably should have shmoo'd the UMI on, another future me problem
I'd like to get the extra throw out of the steering, but seems like it binds up on the nozzle, end link out the back if I scoot it over that far. Need to play with it with a clear head

 

[mrfist9]

So an update on this unit.

Immediately exploded a steering nozzle (cause I'm an idiot). I was super unhappy with the steering cable anyway that was in there. Turns out it was either a GP/b2 cable just shoved in there with the stock bracket bent over it. Weird.

Replaced with a clean freshwater cable. new steering nozzle I spent some time shaving the sides to get more throw out of. Love making this thing spin.

Went after the driveline, put in a better wearing it was spent, stock impeller was also pretty worn out and cavitate'd a bit. Put the 13/16 concord I got from @brapperdoodle with the SN in it. totally forgot I hate this impeller I'm not a big concord guy and it's defo way to short for this thing lost 3+mph. so may go back to a stock stainless buddy, hookers probably overkill for this thing.

Went to rebuild carbs as it idled like garbage as was a pain to get past idle. Took the carbs off and some dummy did this.



Go figure. Carbs were otherwise immaculate despite being salty crap on the outside, stripped screws on the top. Got some fresh carbs from @yamahaulass thanks again man. Came in clutch.

Got it all back together, plumbed back in a fuel selector because well it seems important on this ski.... Runs AWESOME

Idle like a dream first click.

Only 2 issues I need to resolve.

I forgot to put a fuel filter in there like a dummy.
And for whatever reason it bogs a bit under load on the ON setting, which is using the tank pickup I've never used before, and maybe the selector from my stash is junk. Hopefully something simple.

I have yet to open the ebox or the stator cover. But I would be surprised if I didn't find something, it revs FAST. Feels super good. Compressions an ordinary 150, so maybe an MSD box or shaved flywheel something going on.

 

[mrfist9]

So this things kicking my ass! It's got some weird intermittent issue once I got it hot and wet in the hull. Feels like it's leaning out, but there's zero indication of that.

All we've touched is carbs, pulled them back off. All looks kosher.

Went through the unit chasing phantoms. Stock flywheel.. no water in there. Stock electronics... No water in there either.

So. There is this. I'm going to address this. Hoping it's my problem.


Stator wires are a vinyl taped gumbigambi schmoo mess. So previously they were wrapped over top of the intake. I threw them to the side of the hull. Now it just sits in the bottom. I'm HOPING this wiring is junk and is just shorting out when it's soaked in water. Which would make sense it acts worse in right turns.

Id say you probably found your issue. Id cut that off and install a duetch connector that way you can remove the ebox separate from the engine and vise versa. Even if that doesn't fix your issue, it should definitely be addressed. Your main ground goes to the stator from the ebox so any shorting or corrosion there can cause all kinds of strange issues especially if you ride in any salt water.

 

[mrfist9]

Yeah definitely
I run weatherpacks on everything gonna just match it to everything else I got

Whelp. Still kicking my ass. It's beyond strange. It'll run great cold, I got 5-10 minutes zero issues of decently hard riding. Then it started once again. It's super intermittent, it'll come and go. It just loads up super heavily at low speed, And I can often nurse it to higher rpm then it'll be fine until I drop down in speed again. I'm continuing to think it's something electrical. Plugs look great, when it's working it runs flawlessly, no bogs. Nothing.

Definitely seems to accumulate fuel when it's running funky for an extended period. Not sure I'd call that rich, but just smokey after it's acting up.

When it sits and heat soaks. That's when It really acts up. The only consistency I can seem to find is if I really beat on it through the issue. It runs better. If I can get it past the strange hesitations... It'll consistently hit top speed no problem.

Next steps coil / plug wires. Gonna actually hit the manual and measure stuff. Not sure that'll show much when it's cold.


But an update of what I have done.

Plumbed in a bilge



Redid the stator wiring with weatherpacks (I'm floored this wasn't the issue)


Went down to 3/16 tygon lines the 1/4 didn't really fit well. Little better routing this time too.

Sounds like you could have a leaking oring on your seat of the needle and seat or possibly a leaking needle. Wouldn't hurt to do a popoff to verify. Its important to know the actual popoff psi but also you can pump up the pressure a few psi below the popoff pressure and let it set for a few minutes to check for a leaky oring or needle. If you see any groove in the viton tip, then the needle is worn and needs replacing. This can do this when the engine warms up as pressure builds up in thr tank as you ride. I reread your posts and it looks like you went through the carbs already. Did you do an actual popoff test to verify your carbs are good?

I did they're brand new 1.5 N/S I got from @JetManiac
I hate to pull these carbs a 3rd time, but guess it can't hurt to really inspect.
I wanna say it feels unlikely to me, because lets say it's leaking and just dumping so much fuel I can't run past it. Putting it onto the trailer I did a 45second ish just WOT what must've been 4000rpm bog all the way to the trailer and cut it
pulled plugs and they are a lovely brown, I would've expected if it was rich and trying to burn all the excess fuel plugs would've been beyond fouled.
Not what I found at all
