This is my first time on this forum so... Hi everyone

I'm looking for a low maintenance supermoto and KLX 250 might be the one. Manual says that valve clearance inspect, engine oil and filter change intervals are 12 000 km.
My question is how often engine rebuild must be done and how much those maintenance intervals change after all those modifications that we can put in this bike to get some nice power? I mean big bore 330 kit, new exhaust, camshaft mod, new EFI map etc. etc.
Also how fuel consumption change after modifications?

Anyone can help?

 

rly noone now? I saw tons of pages on this forum about those mods but there is nothing about maintenance, you always focus on the performance. Just tell how often do you change oil, check valves and do engine rebuild after those mods. Is that so hard?

 

I do not remember any posts about the maintenance intervals changing due to the mods you've mentioned.

 

I wouldn't dream of running 12,000km oil changes on a stock bike, yet alone a modified one. I do however only check valves every year.

 

I put mine on a KTM schedule. Oil that is anyways. Every 10 hours it gets a change. After all its only a qt and a half. Valves I will check in the winter.

 

These bikes don't need much 'maintenance'. Ride them hard!

 

Thanks for your input guys. So can you tell me how exactly your maintenance schedule look like with stock and modified KLX 250?

 

Keep an eye the oil and change it as needed. Make your own intervals.

 

I change the oil every 2,000km or less if I off road alot. Air filter is cleaned when it gets dirty. Valves get checked ever winter. Steering and suspension bearings done at the the same time.
I would think the fork oil should be done every other year.
Spokes and chain I try to check weekly.

It's pretty basic on these bikes.
One thing I can't seem to get a straight answer to is how much you can adjust the valves before you need new valves and seats.

 

When you can't get a shim thin enough to bring your valve into spec, it's time for new valves. The seats usually hold up much longer than the valves.

Ride on
