flyingbrick Posted August 21, 2021 Share Posted August 21, 2021 Dude... Nice bike! Doesn't get much better than that. Doubt it will take you long to get it running like new. That color and tail looks great in my opinion.. 1 Quote Link to comment Share on other sites More sharing options...

tortron Posted August 24, 2021 Author Share Posted August 24, 2021 I'm told they are pretty indestructible, don't have the 750 or 400 tax either, but AFAIK they are "the same" Quote Link to comment Share on other sites More sharing options...

tortron Posted September 10, 2021 Author Share Posted September 10, 2021 Checked out the cylinders today. Head gasket is damp on the edges, they have some O rings in there that dry out and cause leaks, that might be part of it. Plugs 1-2 were rich but OK, some oil on the threads but seemed to be coming from a valve cover leak Plugs 3-4 oil contamination and oil up the threads. Did a leak down test. #1 15% #2 can't get the fitting to thread in, plug goes in and out fine, idk #3 40% #4 75% On 3 and 4 all the air is coming out the crank case, so they have ringed their last ding I'd say Quote Link to comment Share on other sites More sharing options...
tortron Posted September 10, 2021 Author Share Posted September 10, 2021 There are two different headgaskets and no way to tell until you pull it apart, so I will have a look at it later. Hopefully the cylinders and pistons are within spec and I can just hone, rering and regasket it 2 Quote Link to comment Share on other sites More sharing options...

tortron Posted September 10, 2021 Author Share Posted September 10, 2021 Well not so bad All the cylinders are silky smooth, so sign of crosshatching left, pistons are snug in the bore, so I think a hone and ring will do the job. Will measure the bores tomorrow #2 has half of my sparkplug threads in it, that explains why the plug was screwing in, but the leak down fitting which is half the length was not. It wasn't even that tight and the bits don't feel like aluminium to me, I think it's been stripped before and jbweld or threadlocked in there tbh. Will look at a threadrepair thing or look at the spare head (which I now feel was supplied for that reason) Head gasket and orings were not original honda, head gasket is full of absorbed oil, but the o rings were new. The rubber bungs that stop oil running out of the valve cover and down the head bolts were siliconed up. So general dick fingers have been at it I think. 5 Quote Link to comment Share on other sites More sharing options...

flyingbrick Posted September 10, 2021 Share Posted September 10, 2021 My KTM had a shit battery when I got it and was sometimes a cunt to start.. used to HATE gas stations.

tortron Posted September 10, 2021 Author Share Posted September 10, 2021 Measured up the cylinders Not warped No scratches Nice and parallel Stock is 59.800-59.810mm service limit at 59.90mm I'm getting 59.805 ish right across the 4 at all heights so an ideal outcome. Will give them a zing with a dingle hone, new gaskets (cant get genuine which I'd prefer so same as what was in there is what I will settle for) and new standard rings, which I can get genuine. Base gasket was real brittle, and some crap was under the gasket. So I'm figuring there was a gasket job done to replace those O rings that leak oil, and it was a shit job where base gasket was left and just the top ones done, smoo up the head and away we go. Should have just done the job correctly and been riding the bike for 10 years m9 4 Quote Link to comment Share on other sites More sharing options...

I used to start my morrie by popping the bonnet, holding the choke lever by hand, and pressing the in engine bay starter switch. So many crowds 1 Quote Link to comment Share on other sites More sharing options...
