reliability of a 16mm stroker?

reliability != stroker


my guess is about the time a 16mm is broke in its time for a rebuild

How did you arrive at that conclusion?

What specifically makes strokers less reliable?
Does that mean that a 66E is less reliable than a 701 by a factor of a 10mm stroker?

note that i said guess, based on what i have read. i dont have a 16mm DASA and never will. my input is useless i wanted to state that if he wanted something reliable strokers aren't known for their reliability, expectually considering the size hes inquiring about.



btw a 66e is not a 10m stroker, its 10mm longer.

get off your high horse matt, go troll someone else so the thread can get back on topic.

With proper lubrication, minimal water ingestion and everything being dialed in correctly, I see no reason why it would not last awhile.

Even if you want to freshen up the crank bearings, hone and rings, your talking way under 1 G unit for sure.

I think that the gp800 motor does have a 10mm longer stroke stock then the 701. 80mm pistons 78mm stroke. I could be wrong

It is a matter how far you take the revs, don't want to go past 7000rpm regularly as the piston speed is very high. 66E has 78mm stroke so is technically a stroker compared to the 701's 68mm

66E's are time bombs compared to a stock 701! But, the 66E is built stronger (bigger bearings, beefier castings, etc.) than a 701.

A stroker crank with stock length rods will put higher side loads on the pistons, which will increase wear.

Doing a double bf will probably add some stress to the engine.

16mm stroker crank is almost 25% longer than stock but the crank/big end/small end bearings are the same size so based on that I would expect a much shorter life before needing a rebuild.

You gotta pay to play with stuff like that.

25%! C'mon man - it's only a 5/8" stroker. My 5/16" stroker is holding together just dandy. :)

Like Darin said though, it'll have a shorter life than stock. HOWEVER, when you consider that Yamaha designed 'stock' for 1000 hours, a shorter life really isn't that bad.

Bogie told me that he ran like 3 LONG south florida seasons on the pumpkin (1000cc 10mm stroke) before it was ready for a teardown..

and the only reason it blew is they took it out on a racecourse and let a pro racer run it WOT all day long

next day it was hard to start but still ran but was ready for pistons...

Not that this really counts for anything, but, I have a 5 mil runnin 85mm flat tops and the only 'rapid wear' that I have found is skirt collapse on my pistons after 160 gallons of fuel. That is 1 full season for me therefore I see no problem with my lil stroker.

how ofter do you have to pull the 16mm Dasa stokers apart for inspections/rebuilds if you had the SB Products cases and DASA cylinders and their crank?

Fixed your post for you...

I just stumbled onto this thread, kinda slammed at the moment, but I would like to comment later on today.

They use 144mm Honda CR500 rods just like Miller uses in his +6mm 951 strokers. both 84mm stroke Rod ratio is 1.71

This is the same ratio as you guys running 5mm stroker Yamaha twins with 125mm OEM Rods.

Exactly.

1000 hours at WOT...all 65 horses.
