2008 crf250r hard to start and run... HELPšŸ˜‚

Alright so i recently had my bike apart for changing shims forĀ about a month due to lack of timeĀ but after I put everything back together correctly(I'm fairly certain I did) it would not start so I checked timing etc and it's all correct so I started bumping it and wheneverĀ it did finally start if it was below 4000-5000 rpms it would just die any advice on what to check or try would be greatly appreciated!!

(always maintained very well with oil, filters, air filters, cleaning after every ride, etc not just a pos I throw around)

If it was sitting it maybe the carburetor, maybe try to clean that out and see if that helps.

Sounds like timings a tooth off.
