Nick60 Posted March 31, 2011 Share Posted March 31, 2011 Hi guys, The sun is shining and I need advice to get me back on the trail. I'm just about to put the top end back together after a rebore. Everything is great but I have noticed that one of the two "spacers" on the right hand barrel studs is missing. Don't know why I didn't notice it before but it must have been missing when I got the bike as I certainly didn't loose it. Can I reassemble the barrel without it ( there is some movement when I put the barrel in place ) or is this part of the reason for the partial seizure that happened before I got the bike. Until I stripped the top end the bike was running quite well, Should I be worried? Thanks in advance for any knowledge. Nick, in sunny Bulgaria.

Moderator Airhead Posted March 31, 2011 Moderator Share Posted March 31, 2011 I think you are referring to the locating dowel part # 91810-16016 I wouldnt use the bike myself unless both are fitted, is there ANY possibility it has dropped into the crank case? thats a worry too Thats why rags should be shoved in there when removing and re fitting the barrel, until there is just enough room to get them out.

Thanks old boy ( can't bring myself to call you "old git" when you're so helpful ) I think we're speaking about the same part, a "tube" around the barrel stud, two of them, both on the right side crankcase, the base gasket holes are larger to accommodate? I'm 100% sure I didn't drop in into the cases, rags in place and anyway the groove it should sit in is full of gunge. I'll try to get a new one or get something made up. Cheers for the advice. Nick.

YPVS TONE Posted April 1, 2011 Share Posted April 1, 2011 Were they located in the barrel when you took it off, if so did the people who did the rebore take them out ? Tony Link to comment Share on other sites More sharing options...

Tony Hi Tony, Thanks for your response. No, I am certain that the missing dowel was missing when I stripped the barrel off. My question was not about where it's gone but whether I should re-fit the barrel with a missing dowel. The engine had partially seized before I bought the bike and I'm wondering whether the barrel might have been slightly mis-aligned because of the missing dowel and whether that might have had something to do with the seizure. General consensus is that I'd be nuts to rebuild without the dowel anyway, so no further doubt.... buy or make a new dowel. Job sorted. Hope to be back on the road/trail over the weekend, after checking oil pump settings of course. Thanks to all for their answers. All the best, Nick.
