New heart for the old girl
allankelly1:
Hi all
Always was planning to rebuild the engine on my old girl as the “last piece†of the jigsaw
Trouble is it’s never a “good time†to do it with a running bike so decided to buy another engine so I can do the work without the old girl being off the road too long
So picked up this today from Ted ( many thanks again Ted)
Now it’s home and as it’s a “no rush†build going to not just do a rebuild but planning to do possible the following changes as well as a complete rebuild from the sump bolt to the top of the rocker box
Take it up to 460cc
Yoshi stage 1 cam
Get the head ported and sorted and possibly swap to Amal smoothbores and pods
And no doubt a few other internal tweaks too as been reading you can update the oil pump to a GL1000 with a modified oil pump housing?
Once done should be a special bike with some nice additions
Lastly no doubt along the way I will be asking lots of questions but first off need to build a engine cradle so the motor will sit nicely on the bench as it a bit more heavy than the RDLC engines I have built in the past so don’t fancy it falling over
Catch up with you all soon
Best wishes Al

Nice 1, any broken fins ? even has the rare kickstart :)

Yes no broken fins
As for kick starter I had one spare as with Raask rearsets on my old girl you cannot have a kicker so fitted this to see if it spun over which it does

Sounds like the ATF I put down the plug holes has worked!

Yes it looks good for my first initial peek inside.
Had a look at the cam and the bearing journals it runs in as I read somewhere that infrequent oil / filter changes cause this area to become scored and all looks ok
So that I hope bodes well for the rest of the insides including crank and box
