I had the same symptoms on my MK2, my bike was running fine but would intermittantly pump oil out of the breather. The fix for mine turned out to be the small oil seal that sits behind the oil pump. You have to remove the clutch cover to get to it, when I took mine off the oil seal had fallen out of ...

When I called LT they confirmed that they install C3 normally, the standard item I received was an error in their stock. Since I had already installed one 63/28 I sourced a second locally and returned the C3 for a refund. Since a 63/28 came out I assume it is an acceptable bearing for the ...

Hi Knackered

I shall have to postpone the job and call LT tomorrow to see if they will exchange it for the standard bearing or if they suggest I install it anyway.

Thanks Mike, that is an useful website. Their explanation on C3 confirms that they can feel loose until running at temperature, I now wonder if the other would benefit from being a C3 as well.

I am just in the process of trying to reassemble my engine after a main bearing failed.

I have the new bearings from LT but one seems to be loose. The part numbers are also different.
One is simply marked 63/28 and I have fitted this in the left crankcase.
The other is marked 63/28C3 and I am ...

Thanks for the reply, I'll try to remove the balance shaft today to inspect the bearing surface. I suspect that is the reason the drive gear was removed in the first place.

I have read through the what fits what post but I am unable to determine if the balance shaft and drive gear are interchangeable between the Mk2 and Mk3. I need a gear and woodruff key and there is a whole unit on ebay at present.

Also I seem to be unable to find things with "search" at present, is ...

I'm just outside Leighton Buzzard. I measured the diameter of the pin it is 25.7 mm this obviously isnt the same diameter as the part pressed into the bottom yoke.
The KDX headstock is 185 mm high.

Hi Gooner
I still have the whole front end, as to will it fit I dont know. I will measure the pin height so you can see if it is similar, if that looks something like the same then I guess it could be made to fit if appropriate bearings are available to match the pin with the diameter of your ...

Hi Jon, thanks for the information I found your post and will have a look into the clutch side this weekend.
Keith

Hi, thanks for the reply. I have downloaded a Japanese manual earlier but the resolution was so low it wasnt much use. I bought the service book from LT and I am still not convinced that I didnt get an incomplete copy. I have been looking at the balance shaft (Ithink), on the engine I am working on ...

Hi, my name is Keith. I purchased a Mk2 in August this year only to have it stolen in September. The police recovered the majority of the bike for me after two weeks and having paid the recovery fee (how annoying is that!) I set about trying to source the parts I needed to put it back on the road.
