hi there,
ive got a 2000 wr400 and a few weeks ago i had a white bothers e-series system fitted (5 plates). i rode it home steady due to having new tyres fitted at the same time.
ive not used it since and last night i decided to change the water pump due to a slight weep......all went well and it no longer weeps :eek:
while i was doing this i fitted a new air filter with plenty of oil on it......and when i came to kick it up.....it was a pig to start and kept cutting out.
ive taken the filter out and dried it a bit......it now starts first kick as usual and runs ok ish.....but it feels like its running out of steam too quick through the gears and when ticking over if i give it a some revs.....it bogs down and cuts out.
sorry for being a bit long winded but i didnt want to miss anything out.

PLEASE IGNORE - was due to me putting to much oil on the filter.....runs like a good un now its dry :thumbsup:

According to white brothers, the e series DOES NOT require rejetting.
I put one on my bike a month ago, but due to everything being covered in snow and ice, it hasn't been started yet, will report on it once I do fire it up.
