Hi, hopefully after spending some time searching this forum and the rest of the internet you can help me confirm a few issues and resolutions for my bike.
Below is a snap of the bike i have just purchased. I have had a WR250F for the past 2 years and fancied something with a bit more power.
My issues so far:-
1.) I noticed my bike had an oil leak after i ran it in my garage for 5 minutes. After cleaning the bike and resting it against the wall i found that i had a nice little puddle of oil and it seems to be coming from the main drive shaft. (see photos below), Can some confirm that the link i have posted below is the correct part to fix my issue. I am 99% sure its correct even though it does not state it fits my bike in the link i believe the All Balls Part Number 25-4019 seems to be correct.
2.) My second issue i noticed when rolling the bike around the garage and grabbing the front brake. When i apply the brake there seemed to be a jolt feeling i could feel. I think it may be free play in the head bearings, but is there anything else i should look for?
I am going to have a look at the old head bearing and probably buy the head bearings in the link below
3) On my WR250F i have an oil bleed bolt that you undo after an oil change to confirm you have oil pressure, The photo below shows my YZ400F 98 and there seems to be a ball bearing in place of this bolt? Why would this be like this? My brothers WR400F has the same ball bearing in the same spot. Any Ideas?
4) Finally........................ It seems my bike has a major bodge on the sump plug at the lowest point on the engine. It does not leak but what should i do with this? I have not tried to undo it yet. Any suggestions would be appreciated.
Thanks in advance for any assistance you can offer. I have used the search function quite a bit but would like your opinion on my specific bike with the photos shown.
I will update this post with some good quality photos as i fix the above issues and anymore i find to hopefully help others at a later date
Kind Regards Ian
