The biggest headache I faced was fitting the mc21 swingarm due to the linkage mounting point being higher than the mc16 item. There were 2 available options to me, either making new linkage plates or modifying the swingarm and moving the linkage point. Now the latter would have been the best way, but also the hardest. The former was running the risk of destroying the shock absorbers action and spoiling the suspension setup.
BUT.. before comitting to chopping the swingarm up I thought I'd just try going down the plates route, just to see how the back end would behave. Doesnt make sense to try the hardest route first does it?
So I got some gash alloy plate, did a few measurements and got the hacksaw out;
Lo and behold it worked ok, I even had to back the shock off (fireblade item) from its max hardest setting as it was too stiff with the new setup. Ideal, it now gives me more room to play with the shock settings as it was a bit soft when on the standard bike. The action feels ok, but the proof will be in the pudding as they say..
I'll get some proper plates made up now!
Apart from that, I've put the new subframe on, fitted with a little bit of modifying;
Chance to fit the rear wheel now too, looking better already!
I found a crack in the frame, on the front down spar. Lucky I spotted it and its made me think it could be worth getting the whole thing X-rayed in ndt at work. Not sure what caused it so would be worth checking the rest of the bike out.
Another job was to modify the lock stops as with the mc18 yokes there was bugger all lock!
Then a trial run with the tank and seat unit..
Thats all for now...
