CB1100F Big ends and Yoshi can advice please
« on: June 15, 2008, 10:33:44 PM »
I know, it's the first time I have I posted, and then it's just 'cos I want something - can you forgive me, Yes?, good!

Having just got the CB1100F on the road for summer (my GT550 needs small ends so SORNed to do at my leisure), I now find the big ends have gone (knocking from 2500rpm up) - bunch of arse, I'd just got the ignition sorted! Anyways, I am gonna pull the big ends myself - you can get to them from the sump pan...

Sooo...

Any suggestions? I'm gonna leave the heads on, but drop the bike on its side and lift the frame off, a removable frame member helps. The rest looks fairly straightforward to me, and I know you will throw your hands up in horror, but being on a very limited budget, I hope only to replace those that are noticeably damaged.....

Secondly, while the exhausts off I thought I might refurb it (it's a Yoshi)...

The downpipes and collector have come up nice in Satin VHT, I have the badge off and wanted to pull and repack the baffles. I drilled the 3 rivets out, and it looks like the baffles should just pull out....

Nothing, not a thing, nada - can't shift 'em. So just to check - the baffles are removeable, and am I right in thinking that all bar the outer ally sleeve comes out. If this is the case I will just have to exert a touch more welly...


Oh, and any tips for when I bolt it all together..?

Hi,
I would have thought that if it only starts knocking above 2500, then I doubt if it is bearings.
If the bike has been laid up, it could be the carb jets/ channels gummed up. If your getbthe carbs ultra sonically cleaned it may clear you problem. Cheep than an engine rebiuld.
If rebuilding replace cam chains and tensioners! Money well spent.
Regards
Steve
