5mm stroker with 88+mm bore?

[NathanMoore]

I'v been trying to do some research and checking various p/v cylinders out. Xmetal has the stock stroke 88+ cylinder, and it looks like their other cylinders require a 8+ stroke. On Dasa's website they have the 85mm available in a 5mm, but looks like the 88+ is only available in 6+ strokes.

Is it possible to get a cylinder set up for +5mm crank, and 88+ bore from anyone? Is it possible to buy a cylinder, such as the lamey 88 bore with +6stroke and have it machined to accept a +5mm crank or maybe even a +4mm crank? Or is it possible to add a stroker to the xmetal 865 kit?

Reason I ask, I can get a stroker crank for extremely cheap from a buddy, he said he thinks its a +5, but it might be a +4. So since its cheap id like to run it. And if I can i'd like to run 88+ bore to get around 900cc.

Yeah I know, I should call them directly, but dont really want to until im positive what crank I have, and im ready to buy..

Thanks!

Nathan,

DASA could get you an 85MM 7 port cylinder for either of the cranks you mentioned, but you need to know what it is(and make sure it is good) before you buy any cylinder.

At this time, DASA does not offer the 89+ for anything less than 6 MM stroker.

Many here can attest that a 5MM 85MM will yield plenty of power.

I love my 5mil 85mm Lamey!!!

 

[waterfreak]

the reason is that the 6mm+stroker cranks uses the longer kawi rods which are necessary because of he lesser rod angle when going with he bigger 88mm+ pistons

 

[NathanMoore]

Thanks guys,

So what if I were to have the crank rebuilt with longer rods? Is that possible, and would it that change anything in be able to run the 89+ cylinder?

Brian, would a cylinder for a +4 crank be the same cost as a +5 cylinder?


Anyone know anything about the xmetal setup? Or any other set ups?

Thanks again!

Make sure the crank is good or at least rebuildable. Yes, there are billit stroker cranks who have seen their last build. You could send the crank to Crankworks and have it checked, for a small fee. CW can do almost anything you want to a crank and they will recomend the best solution for you. If the crank is worth it then decide what to do after that.

The rods are a specific length for a reason.

The cylinder cost is the same for all strokes.

Nathan, I ran a 5mil dasa motor with 85mm pistons the year before last and I could not of been more happy! in my opinion 84-86mm pistons are the best for torque.

 

[NathanMoore]

The crank would be in perfect rebuilt condition...no worries on that. It would be comming from a good crank shop..

I understand the reasoning of lengthening the rods to lessen the rod angle on stroked cranks, but what does that have to do with the bore size? Xmetal has a stock crank 88+ kit that works pretty well according to many?

Why could a 5mm not be built with longer rods?

Iv ridden a few 5mm lamey 85 set ups too and I know they rip, and more than likely be what i'll end up with if/when I decide to pull the trigger :veryhappy:

Just trying to figure out why you can get the 88+ in stock stroke, and large stroke, but nothing in between.

With how many xmetal setups you see on here, I figured someone would have something to say about them???

Thanks again to you guys helpin me out and answering my questions

Do up a 10MM 90MM bore. You will never go back to a smaller motor.

Stroker cranks up to a 12MM all cost the same.

ADA's billet. I am building one now. starting at 88.75mm (Seadoo pistons) Cheap rebuilds. I am using a crank works 5mm crank (no spacer plate required).
Suposedly no bottom half case work is require but we will see when the crank gets here. If it needs any it will be minor.

I like this set up simply do to the VERY reasonable top end rebuild cost. About $300 with boring versus $600 on the x-scream set up. You do not get the PV's, but I am not sure I want them anyways.

total cost with new 5 mil. crank, porting, pistons, billet cylinder, head with domes, BB sleaves, boring and machine work, shipping, gaskets and all will be $2800.00 with me supplying only the cases and the case port work.

If it were not for the added (long term) costs of top end rebuilds and the limmited amount of bores before resleaving I probably would have went with the x-scream standard stroke PV 88mm set up. But in the end it was cheaper and easier for me to do the ADA 5mil non PV.

If I were buying a brand new crank, no doubt I would go for at least a 10mm 90mm bore. But a buddys hooking me up with what he's got lying around for cheap...I wouldn't be able to do it if i had to buy a brand new crank.

I have been looking at the ADA set up, and it looks pretty nice. Just not sure how I feel about a 5 port non powervalve cylinder, when theres 7 port p/v cylinders out. I'v never ridden one, or heard from anyone who has, but would love to hear. Really like the price though. Keep us updated on how yours runs when you get it built sjetrider.

 

[Matt_E]

Ask Crammit, Sportfish, or NJFL about the 5 port ADA cylinder. :biggrin:

I hope theyll chime in here??

I'd PM them.

jack sutton rode the ada with a 5 mil and i dont think he was to happy with the power.

I think he was riding the older 85mm cylinder, not the new 89+ cylinder. Not sure if there are any other differences in the cylinders besides cylinder bore and pistons used? But I talked to jack, and he said it wasnt bad, but thought comparable sized p/v motors were better.

I think I can build an ada for around $1600 cheaper than a dasa or xmetal all said and done, and since im currently running a stock flywheel, and pump...I could put that 1600 towards a total loss or tbm flywheel and tbm cone or maybe mag pump, that I wouldn't be able to afford right away if I went with the p/v cylinder.

So...now whats the better option, a dasa motor, or an ada with a more "complete package" (total loss, pump...ect) right now?

Dasa, and upgrade as u go. U will always know ur build started off right. Not something u settled for in the past. That ADA setup was good but now with other stuff out there
such as the dasa cylinder with design in mind id go that route.

Whether you go with a DASA or not....

I will agree. Even if you have to buy a new one, the crank will seem like pennies down the road compared to being "stuck" with a particular setup cause of a deal you got on a crank.

I can say that the 7 or 5 port doesnt seem to make much difference short of a wider range of pistons you can safely use. I have tried Lamey sleaves (7 port) and R&D sleaves (5 port) in OEM cylenders with better results from the R&D's. As far as power valves, My opinion is, one more thing to deal with and unless you require BOTH top and bottom speed, why bother, set up a non powervalve for low end power and go with it.

Just becasue its new to an SJ 62T motor does not make it "BETTER" just different. I have rode Lamey power valves and lamey non powervalves and I preffer the non powervalves more light switch type power over the powervalves electric motor constant pull power.

Dont get me wrong, as I said earlier, if the initial cost and down the road maint. costs were equal I would have a CHUCKEY motor in a minute. He is the best out there right now for a turnkey motor IMO.

Just figured I would give ya something to think about and in a little different price range as well.
