If you got the high screws closed, you need to put smaller mains in there and see if the rpm go up. Since the low jets contribute to overall fuel at top end, just turn the lows in and see if you get more rpm. Quick way to see if it's too much fuel

The throw is a lot shorter on the 08 too. It's like 3 inches when the 07 is like 3.75 and the old squarenose is over 4 inches.

Yamaha doesnt have screw on boots unless they have been replaced with kawi resistor or screw on boots

Ohm out the stator and if it's in spec, it's the cdi. I'll bet it's the cdi anyway

I used to run them years ago but they were junk just like most lithium batteries. They did warrante a few for me but they werent worth the money. Brandon lawlor was sponsored by them and I see his had some extra sealing goop on all the seams. They die quick when water gets inside, which is...

I got one that looks pretty much like that. Does it say hot rods on the side of the rod? It had nothing to do with water ingestion. Rod just snapped in half probably from a casting flaw. My old friend that died, Henry rapheld, said probably a good idea to have rods xrayed or magnafluxed on high...

I'll take it. PM me your info. Thanks

650 ports are square. 61x 701 ports are angled at the bottom and 62t ports are even bigger than 61x but the same shape. Those are the only 3 port configurations

When a prop spins, it's either too small or its spinning on air. If it's not jumping out of the water like you want at basically a dead stop, why not? Does the motor not rev or does it just spin the prop. 140 pumps are not for bottom end. Old SJ race boats turned 144s into 140 mags and only...

Couch models use a bigger 4 bolt pattern where the head pipe bolts on to the manifold. All 750 standup models use the small 4 bolt pattern and that's big or small pin. 650 manifolds are 3 bolt on top and most aftermarket pipes use the 3 bolt type.

My first tigercraft. Maiden voyage at miller on sunday

I just saw this post. I got the complete running gear out of an octane that fell out of a truck. The idiots threw the hull away. I traded it for a 61x dual 44 setup and an msd enhancer lol

The curved wr3 tail cone works on the blaster. Even the kawi 650 rocket version will fit in the blaster since the hull is wider. Kawi pipe in a superjet rubs on the hull big time. Like I said cause the gromet loop put the chamber to the outside farther

They are no longer available new. $40 each for used. 916 334 3786 if you want some

So it's the same motor as the new sj just in a couch body? I see spark riders doing wheelies all day long. I dont care what you ride, just dont get in my way

R&D dry pipe needs the side ground on a bit for the chamber to fit the hood opening. You can always tell a sj hull that had that pipe in there once upon a time

Garbage crank. Probably hot rods . Been there but with a lot more expensive motor

I dont even hit the green button until I dump some gas in the carbs unless I'm just checking to see if the damn thing is going to crank at all that day lol

I used to throw those 650 setups together with the proper jets ready to rip with intake , carb and filter for 350 ages ago. My prices used to be the highest on ebay, and I got it , until robjetskihaven started charging even more. Foreign countries and up short areas pay premium prices. Some...

I got all that junk for the 650 but when you said 350 for the carb setup was high, I knew you were delusional on price and I'm not wasting my breath lol
