Hi Guys,

Hope you're doing well.

I finally start my TR1 engine restoration. I bought a very tired TR1 with crankshaft dead and I'm planning to make this engine running, install a nice fork and a Z650 SR tank (I've got one! ) and ride !

Last year I bought a 2AE Engine from a XV1000, aiming to remove the crankshaft and pistons to install it on my 5A8 but, trouble just started.. On my 5A8, rear cylinder is scratched, and my front cylinder exhaust valve guide is broken

So now I'm just thinking to swap the cylinders assembly but, notice the 5A8 low cylinder is having 2 seals whilst the 2AE is flat. I compared the rest they look identical. I had few pictures for you to see.

Is anyone can confirm mounting 2AE cylinder is doable on a 5A8 ? Came shaft are identical ? Any advice ?

Thank you !

2AE

Thanks for your prompt reply !

I saw on google that 5A8 compression ratio is higher than 2AE, do you think that really matter ?

Hi Guys,

Anyone succeed to fix a scratched cylinder, instead of replacing it ? I still can't find any cylinder available on Google ..

Cylinder 1 and 2 are identical ?

Thanks !

Alex

Hi Greg,

Glad to hear from you again !

Thanks a lot for your reply, in theory (depending of the current French lockdown) I should be able to know if I need 1 or 2 cylinders this weekend as I’m going to check cylinders and piston size with a true bike mechanic (Yes I’m just an amateur )

I’ll reach you by MP to get more details.

I’ll also try to post some pictures of the beast, this forum is also for passionate isn’t it ?

Cheers
Alex

2 engines aren’t enough to make one running🙄 Iwas supposed to buy a serviceable 2AE engines but I found a timing chaîne guide in the alternator cas when I open it. Not a honest seller 😡

Freshly painted parts

Yep, that's the number. On how to do it, i.e. the table: it's in the Haynes and Clymer manuals and I am pretty sure it's also in the tech-section of this forum as well.

If you have plastigauge available you still may want to check the clearances just to be sure.
