I am having an issue with a backfire on my 90 superjet that is only happening after trailering my ski. Its happened twice and sounds like a shotgun and I'm afraid of damaging my motor. It is an exhaust backfire that blows of my exhaust hose off. Ski runs great after the backfire and shuts off...

Im running two motors with forged pistons for the first time this year. A jetworks 828 and tpe 964. What do I need to do differently? I've heard I need to make sure they warm up properly, anything else? Sent from my iPhone using Tapatalk

Going through an end of the year tear down. Front cylinder has some scoring. Do you think I should have it bored or should it be ok? I cant feel anything when I run my finger over it.

Recently purchased a 1990 SN hull that I am currently reinforcing. All my previous experience is with Blasters and was wondering if this pump was setup for dual cooling or if one side would be for the original siphon bilge. Being that both lines go into the stator section I'm assuming they are...

I purchased a set of 62T cases from js/sj on 6/12. Well, its August now. I was told they were going to be shipped multiple times over the last 2 months. He also tried to say he just hadn't been on the site in a while which is a total lie. He is on the site every single day posting. Then sends...

Thinking about buying this, what do you think its worth? http://cnj.craigslist.org/boa/3895492931.html

Has anyone tried both the TDR waterbox for a B1 and the TDR designed for the b-pipe? Any preference?

Where can you find mounting plates for dual intake manifolds? I can't find them anywhere. Seems like a terrible design in the first place to have the studs on an angle. I'm looking for a spacer plate that would accomodate dual 38s.

I recently installed a used EPIC CDI on my Blaster and I have zero spark. I installed a used OEM tested 62T stator and lightened flywheel from Jetmaniac and new oem coil. I'm pretty sure I hooked everything up right. The only wires not connected are the black and pink wire to be used for a...

Has anyone been able to contact jetworks recently? I've written several e-mails to JR over the past couple weeks about a new ATP ignition for the top end he did for me.

I recently installed a brand new ADA head on my ported 64X. After riding it during break in I noticed fuel/oil puddling around the spark plugs. No bad symtoms. Ski actually ran great. I removed the head and double checked all o rings and everything looked good. I am using NBK B8ES spark plugs...

I am beginning a 760 swap on my B1. I've got a 64x and a b pipe on the way. Planning on putting an ADA head on with 40cc domes and dual 44s. Any suggestions or best practices?

Recently rebuilt the ebox on my blaster because the screws came loose and salt water got in and began to corrode everything. I cleaned off the CDI, ignition coil, voltage regulator, starter relay, and replaced all screws. I want to used some sort of spray protectant before I put it back...

I'm replacing the pump shoe assembly on my 93 blaster. I have removed the steering mechanism and fist piece of the pump. How do i remove the rest of the pump? I can't seem to figure out how to remove the driveshaft to slide it out. Also any tips on how to remove the rest of the old pump shoe.

Looking for some help. I have a 93 blaster with red pipe that will start and idle, but backfires and stalls out when hitting the throttle. This caused the waterbox to rupture (I'm going to replace it with an aliminum one). Disconnected the head temp sensor and it still ran the same way. I'm...
