im pretty sure you can tune the PV's on an Xmetal motor..but you do it through spring changes
When is dasa going to update their website with this stuff?
When is dasa going to update their website with this stuff?
Website updated as of last week sometime.
Finally.
Website looks great
Good to see dasa making a comeback in the watercraft industry
I know they have always been there but it seemed to fall away in the prioty list for a while
Hello Brian,
I live in France and here we have very few of these engines. So, I would like to collect several informations, as kawi big engines market is growing !
Is the package you offer at 2800$ include the port job ? If no how much do we need to add to have an operational cylinder.
Is the port job done on 4/5 axis machines too ? Do you propose different port jobs depending on the client wishes (Low end, mid-top end) ?
Do you have a release date for the big bore long stroke cylinder (78X89mm is this spec is the right one) ?
Is +4mm OEM Kawi crank (78) a good choice, or is that mandatory to go with Bulletproof crankworks custom crank ?
Sorry for all of these question, but I think I am not the only one who is searching for new engine solutions.
Regards,
Seb
Thanks for the answers.
What about the intake ports ? Are they finished with the 5 axis too (to get accurate angles and port area) ?
So the total for a ported cylinder is 3100$ ?
78X90 will give 992cc. Concerning what you said about over square engine, is that a good stroke/bore ratio ? Is the stroke not too short against the bore ?
I think it would be great for a GP engine, but for a FS engine maybe it could be better to go with the 78X84 cylinder even if the displacement is 128cc less... What is your feeling about that ?
And last question concerns the exhaust, what kind of exhaust would fit the best your engines. Wet and dry are still OK ?
We need to mod the head pipe of the wet like on the Yamis to fit the PVs ??
Thanks,
Seb
Our sleeves are custom made for us, the port angles are set to our specs.
The port area/port angles in the cylinder are set by the machining of the ports when the cylinder is machined on the 1st op. Very little manual machining is done on this cylinder, it is for the majority, all done on a CNC machine.
Porting is only changed slightly to accomodate different set-ups.
Yes, the total ported cylinder would be $3100. This is a complete top end. Gaskets, bored and honed cylinder, pistons, head, domes, orings, PV hardware.
The stock stroke(68MM)/90MM bore deal I have posted about, in our opinion, is just too over-square to work correctly, regardless of the hype. That market segment is fueled by marketing and the desire to brag about engine size and the resistance to the cost of a billet crank and nothing more.
The stroke needs to be relative to the bore size. Kawi cranks stock are already bigger than a Yamaha. The small bore cylinder for closed course will be a good package.
For freeride/freestyle the bigger bore may prove to be a higher horsepower package, but at this time, is un-tested to be released. The Kawi may just need a longer stroke/rod to provide enough dwell and crank timing to properly fill a 90MM cylinder to work correctly.
Due to the Kawi case design, any stroke larger than 4MM will only be possible with a billet case to accomodate a larger crank, with better ports and transfer area.
So far the only pipe we have used is a Factory SXR dry pipe. It will clear the PV's with no mods.

Please don't insult a kawi by saying the stroke is 68mm :smokin:
