Had my last ride yesterday for the season. Seems early but that's the way it goes. I have 1234 miles on my '09 now. The PCV with DTR's Chad MAP work very well yesterday. A little giggle on the trail in the Mid bit once at altitude it worked great. I am going to deal with the piston/cylinder stuff this off season. Warranty is done now. I know the "FIX" is having good luck. Another option that was put to me was having the NIK coating increased in thickness and honed to bring new pistons into the correct spec. Power Addition 12.5 head and a little porting. Hopefully this will get me another 10 horse or so. Thoughts on the thicker NIK coating though?
Piston/Cylinder coating option for '09 Dragon
- Thread starter gerrman
- Start date
And IMHO on the iq cylinder I would NOT go any tighter than .006 due to the insane distortion as it heats up to operating temp. The best bet is to use torque plates top and bottom and hone it at 120 degrees. (you have to make your own plates btw) Also be durn sure you have zero clearance in cyl skirt to case fit.
Oh yeah i'd just do the fix kit with a 2010 cylinder, much better/easier deal

Piston/Cylinder clearances
I have been reading a few of these updated posts. If I used the 3022201, 2010 monoblock cylinder with the fix for an 08 800 turboed dragon. What piston to cylinder clearance would you think is safe? Also would it be better to get a remaned cylinder that has been rechromed or nikasil plated instead of a new cylinder? I was thinking the used cylinder might be more stable after being used and already heat soaked.

I would absolutely be putting in new pistons no matter what I do. Like anybody else that owns and likes these sleds, I am looking for longevity, for a pull the rope and go machine. The one thing I have going for myself is that I have had NO engine issues at all with my current sled. With that in mind, warranty done, I feel it would be in my best interest to address any possible future piston/cylinder issues now, while it is still in one piece. The problem is, what's the best current option to address the piston/cylinder issue, but would also work well with a Power Addition head and possible porting? It really isn't an easy decision.
