2013 EC250R - 65Hr Report/Review

[Jakobi]

So I've got 65hrs/2600kms (average speed of 40kms) on the 2013 model now. Its been around 10months since I took ownership, and maybe 9 months worth of riding on it. In that time its been put through its paces mostly in single track, 1st - 4th gear. My initial review can be seen here.

Overall a fair amount of time has been spent dialling in the suspension at both ends, and getting the engine running well. I've been through a few sets of rubber, several front sprockets, replaced the rear rimlock, bent and straightened the shift lever, put a ding in the rear rim, torn the seat to shreds, lose a gromet out of the lhs shroud, busted the clips on the rhs shroud, blown out the bushings in the brake pedal, and cracked the lhs brushguard. Pretty typical wear and tear for the hours I'd assume.

Today I pulled it down, and decided to completely pull the engine from the frame in order to give it a clean up and replace worn parts. On the list:
Replace leaking counter shaft seal
Replace stock chain
New piston and rings
New spark plug
Upgrade to 2014+ outside brake pedal
Replace seat foam and cover
Service and revalve suspension at both ends
Grease all linkage and swingarm pivots
Clean and polish the pipe

First issue today was that the coolant drain bolt. Wouldn't crack, rounded out, cut a groove into it and tried the flat blade impact. Still no cigar. Undid the whole water pump cover and gave it a few slugs with the mallet - it didn't want to come undone either. Pulled the coolant line and made a right mess. Finally got everything off and put some inox in the back side of the drain bolt which was showing signs of corrosion - cut a groove deeper and finally got it out with the impact.

2nd unexpected sign. Pulled the flywheel and stator and noticed a weep around the main seal. I haven't noticed any signs of running lean or air leaks, but may look into replacing it, or at least will monitor it closely.

Tomorrow will clean up the engine some more, and then pull the head for a peek at the piston. I'll snap some pics of things. Let me know if theres anything in particular anyone wants to see.

Cheers
Jake
