Very interested in the Kawi triple if it fits in a blaster.

What motor is going in it ?

Great video, thanks for putting it together..

Looks Great!!! How did you get the shape? Fill with foam and then shape it, then fiberglass on top?

Yes, I just wasn't sure how hot..... I am spinning some high RPM compared to a freeride ski. I will keep an eye on it to see if it gets any hotter, I only ran it for a couple of minutes as I am still tuning, I think I may cut the first seal as well. Thanks

Does anyone know how hot or warm a midshaft gets. On a high 7300+rpm race boat application. I just rebuilt my pump and midshaft, alignment is all good. But midshaft is getting hot to the touch. Hot enough you can touch but not hold your hand on for ten seconds. The splines are well lube...

Yes sound was not the issue, but I do not like the idea of the mess like you said running down the back and getting all over the mats.

Is there an issue with exiting the exhaust above the bondline? I was thinking of exiting in the rear where the fire ext location normally is. Mine is already glassed in there I was just wondering if anyone has ever done this. I know it may be a bit louder but when your riding the rear is...

I am looking at getting JP Flight Lace up shoes. Doe anyone know what the fit is like? Is a size 12 a size 12 or would I need an 11 or a 13?

If if is a setback, what does it use? I stripped my splines and looked and they do not have very much engagement. I have a spare blaster I could steal the parts from but before I strip the other one, I just want to make sure they are the same. Thanks for the help...

Does a 148mm Skat pump on a B1 use a stock driveshaft???

I have a 5 mm stroker crank and ported/clearanced 62t cases I am planning on selling. Any idea what they are worth. There have not been many listed for a while.

You can get decently priced race fuel from Pro Racing Fuels Mississauga, Ontario (905) 858-9320 They had their Mark 4 (114oct) last year for around 4.50 a litre and I was mixing it 25% to 50% with pump gas with great results on my triple piped GPR last year. Much better than C12 or C16

Thanks Chuck, I don't know if any of you guys have worked on the GPR or not but with a single pipe on it, its next to impossible to get at the high speed screws. My arms look like I have been fighting a tiger from trying to get in there to reach them. The closer I can get them before I...

Perfect, thanks, I know you shouldn't run at less than 1/2 a turn I just didn't know where to start with the next size down.

It is a big bore Yamaha tripple, I know I am close on the jetting I just need to know approx where to start with the screws when you downsize one jet size with the mains with the screws almost all the way in. Do I start at about 2 1/2 turns out and then 1/4 turn in at a time from there?

If I have a motor jetted rich with 147.5 mains in it at 1/2 a turn, and I downsize to 145 jets what would be the reccomended starting position for the screws. Thanks

The rpms were around 7000. The restrictor was in the whole time, just dried out the pipe but didn't richen the screws enough, I guess...

The headpipe diameter is 47 or 48mm will double check today. The timing I thought was 20 deg I will check it tonight, I found someone with a piston so should have it running. The setup was only running for 10 to 20 min while I was checking the plugs and it was only reving out to 6650 until I...

What do you mean by headpipe outlet? Between the Cyl port and the pipe or between the first and the second pipe. I'm just looking online now to find someone who has 83mm pistons in stock to order them. The Bore seems good no real marks and it has next to no time on it since it was bored.
