I remember reading a thread about some of the early 850s having a different engine? I have an early one and was just curious which mine was. I believe it had to do with the cylinder wall. I have searched and searched and am unable to find the thread. Thanks

 

I heard of the 800 being called a 800 H.O at some point due to a change of some kind.

The 850 only has been out less than year I think so I doubt they had time to do anything yet.

 

Some of the 850's have nicasil lined cylinders and some have iron lined cylinders.Pull your seat off and look at the back of the valve cover for a sticker indicating what engine you have.

 

Thanks Plumbob. I was spelling nicasil wrong. It is nicasil. Hope it is a good thing.

 

What's the difference? Also...was there a cut off date from one type to another?


Thanks!

I dont know if there is a date but look where plumbob said. It should read to the effect LEO85011. If 11 is the last 2 digits it is nicasil. If the last 2 digits 12 it is iron. You can search it. The consensus is basically nicasil is good but dont know why they stopped putting them in. It could be cost. There could have been a problem. Dont know.

 

the nicasil cyclinders are supposed to be stronger and longer lasting, but i think you can bore out cast iron easier. not 100 % sure

 

Thanks for the info! But it is really interesting...why they would change something like that. Humm...very interesting indeed...

with nicasil you dont ever bore it out..you resleave it. but it also takes some serious damage to mess up a nicasil cylinder

 

yea kinda like the a arm change and the ball joint change those are the reasons i traded mine in dont get me wrong i do miss the xp that was one hell of a ride it was just the reliabuilty issue i had so i went back to the tried and true sp the xp is still a far better ride hands down if they make a new one next year i will be going back
