Finally got my 2018 out for a full weekend and had my first (mostly) trouble free trip thanks to some (ok, maybe more than just some) help from Mr. Sled rebuilding it. Previously I had coolant leaks, continuously blown belts and studs breaking off which all killed trips. The biggest issue all weekend was the speedo fell off the chain-case.
The coolant on the machine would leak as soon as I shut it off. This turned out to be a broken exhaust clamp from the header to the turbo below the gas tank!!! What surprised me is the machine wasn't unbearably loud, quieter than a stock 900cc two stroke.
If I did more than 1/2 mile at wide open the belt would blow. After resetting the stub shaft and advice from Thunder Products we set the offset to ~57-58 mm depending on what time we measured. I ran 820 miles this weekend without a belt issue. A couple times I ran 10-15 miles at 90+ mph without issue. I will replace the belt before the next weekend just to be on the safe side though.
After fixing all the above issues all I can say is wow! Corner to corner performance on this machine is insane! Running stretches of trail where my 900 2-smoke would top out at 60-70mph before braking for the next corner I was seeing 70-90mph speeds!
