BB Lamey Sleeves?

You can do a BB kit on a Lamey correct? What size pistons can you go out to and what are the draw backs to doing a BB lamey? I have heard of 87 all the way up to like 90mm but only hear about them in passing.......no specifics? Any info?
 
All Lamey's are set up for 85mm unless otherwise ordered. I had a 5mm PV with an 87mm bore. I never actually ran the motor, but I have heard of people going a little past that. A friend of mine had an 8mm PV 85.5mm bore Lamey and that was a nice motor. Tons of torque. Plus the lamey sleeves allow for a lot of bore range.

If cost is an issue, you might want to see what pistons are avail. and @ what cost then go from there. Tricky would know on both I would PM him or hope he chimes in.

Do these use Yammie pistons larger than 86mm? Who sells them?

If you can find them, the KAWI flattops work great in this set up and they are much more cost efficient than the R&D flattops that are $189 ea. and on Riva carries the R&D's lately. To my knowledge there are no Yammaha pistons that will work over 84mm domed.

In one of Pat 'Bogie' Bogart motors I built for him is a Lamey P.V. 5mm stroker X 88 mm seadoo 951 piston = 888 cc's. Lamey sleeves are maxed out at this size and will need to resleeve when needing a rebuild. We had to custom CNC the ADA yamaha head to fit the 951 type domes (also had to make custom domes too as the 951 ADA domes have the o-ring groove to far out and won't seal on the lamey block)
I haven't bought any... but I see that R&D has up to 86.5 pistons listed on their website. The dis-avantage to this big bore is you cant use ADA head with their domes as the o-ring will be in the bore...Must use the R&D head and domes for this big of bore. Phil at CrankWorks builds all the stroker cranks now...8-10 mm cranks are all 133 mm long rods. The motor I'm working now will be a Lamey P.V. 8mm stroker x 88 mm bore/special custom flattops = 924cc's.
Another Lamey that's in the works is a P.V. 5mm stroker/85mm flattop = 828cc's

I figured it was allot of work to get the head configuration right. That 8mm X 88mm bore lamey sounds killer. Why not do the 10mm stroker? Cases get too thin for comfort?

I am running 86mm R&D pistons in my dominator flattop, I had the domes cut by Speedwerx to 86.5mm 26.5cc so that I dont have to buy them again for the next bore. The Speedworx, UMI, cool head and Quite a few other heads work fine at 86.5mm as they all use same domes, You may me right about ADA domes, but I have found my Speedwerx head works as good as ADA and Ideally should cool better than ADA domes. The lamey sleaves are definateley more flexible on what pistons you can use due to ring pin location than the R&D sleaves, I would not try SeaDoo or Kawi pistons in the R&D, kinda stuck w/ R&D pistons only.
The motors your building aught to be some friggin arm stretchers fo sho.
Anyone try ADA's new big bore cylender yet?

Yes I just finished one, ADA billet block w/8mm stroke, it came out to 967cc's
It's done sitting on the bench waiting for the WaterCraft hull to come back from the paint shop and will have to assemble the entire boat! In a few weeks hope to have a report on how it runs.

what would like to get a 800cc or larger for the times I head out to the river (flatwater). Keep my current setup semi stock setup for the surf.

what is the cost for the motor setup and carbs? Could I get away for less than 4 g's. I would problably need a diffrent pitch prop.

I imagine I can keep my 61 x electrics, msd enhancer, coil and such.

If you set them in the right place and use the right piston and head combination.
I build them quite a bit, PM me for any more details
