I would like to see a version of this motor with 86mm bore x 76mm stroke. Would be all over it.

Been running Flame TS2 all season and it has been working very well. Zero issues.

Pipe is in Dry Pipe territory power wise with none of the dry pipe hassles. Does not bolt to the head like up and over dry pipes , so chamber can be removed easily by just loosening hose clamps and lifting out. Goes back in just as easily. Clears power valves with room to spare and...

This new chamber is working very well on my 8mm Judge powered SuoerJet . Good power all the way through and revs to oblivion.

Try using a battery cable to ground the system.

Yamaha is left hand thread and only needs about 8ft lbs or hand tight. L Kawi has right hand threads and needs to have a wrench put on it . Do not recall the torque , but somewhere between arm tight and shoulder tight.

The yellowing is on the surface. Look inside one and you won't see the yellowing. I cleaned an old one up a while back. Laquer thinner for the grease then sanded it. Looks ok now.

No matter what the spray pattern looks like with pipe off on a garden hose , it's gonna be a lot different with 7,000 rpm exhaust gas blowing through it.

One percent of stroke. Wax is right.

Rear bearing is already up against flange of tailcone . No room to move it back . Pump uses a 5205 double row in front 20.6mm wide. 6205 in back 15mm wide 3mm wouldn't be enough. Had to cut back 8mm total.

You could machine the step on driveshaft so the prop goes on further . That means breaking down pump and new bearings , i run ceramic bearings and there not cheap Machining pump would not help. Would make gap bigger. Before the cut back , there was an excessive gap between rim of prop and...

I had to do additional cut back on the props for 144 Maxx pump. Seems like it was an extra 4mm vs skat mag cutback . Even the cutback on a skat mag is different from a stock pump. If it gets to close all you need is a shim or two.

Not much left of ski he was on or poor old Ted

I put a Kawi Dasa in an 09 SJ. Rad Dudes bedplate , cold fusion Yamaha coupler on stock SJ midshaft. Cold fusion kawi coupler on motor. Option A- Get a midshaft approx 38 mm longer than stock I went with option B Option B - Drill new holes in bedplate approx 38 mm rearward. The holes...

Depends on your definition of excessive. According to Jan Thiel , a 2stroke engine with an expansion chamber that is de carbonized is more prone to detonation and will make less horsepower , than a motor with a dirty pipe.

My Beta unit has been trouble free as well as a 2nd HX3 I picked up last summer.

Fresh set of battery / ground cables may be what it needs.

Not a very cost effective way of getting a hull . Cost of new SJ minus 3500 and you just spent 5k on a stock hull . Should be able to get a hull for less than half that . I found two .

Got to watch out for over tightening prop , especially with threads lubed . Tourque spec is 13 ft lbs . I just barely snug it and still have to stand on a four foot cheater piope and jump on it every time , after heating the hell out of prop .Left hand threaded prop tightens itself under power...

No way would I have my engine cases powdercoated . 450 degrees no thanks
