Forks advice

<< < (4/6) > >>

The plot thickens!
New OEM seals arrived today from Silvers, i was told the Hagon order would too, but no joy - anyway, stripped the forks and changed the seals in readiness for the springs - total oil quantity was around 300ml from both legs and it was 'fairly' clean ATF that came out. The springs however are already progressive - I have no idea if they are the right springs though until I can compare them to the new ones that I'll be fitting, total free length of the old ones 465mm - obviously longer than stock. They might be going on e-bay soon - or, if they look and measure the same as the Hagons I'll offer them up on here.
Checked the head race too and its tapered, now readjusted.
Can't wait to get out on it now! hopefully be ready for a spin tomorrow evening.

did you re pack the bearing with grease!!!!!!!!!!!!!!!!   marine grease is good

Little bit of an update:
New suspension went in front and rear (end of july) - improvement, but still didn't feel right, especially the front end which was following every little blemish in the road, it felt dangerous - from that point I knew I had to change the tyres.
I installed the Bronze swingarm bushes last week (dead easy really) and a new set of tyres (Avon Roadriders) Just been out for a run and I can say the bikes handling is back to how I expect a bike to handle. The swingarm bushes may have helped a little, but I would say 95% of the improvement is with the tyres. I've opted for a 3.25 front and 4.0 rear. Only done about 20 miles and still running the shine off of them, but I'm happy.
The moral of the story: don't buy Continental supertwin tyres
Just got to sort the dodgy carbs now...
Nearly there, but I can't see me doing much more riding until well into next year - I've declared winter!

interesting about the tyres,I just took off a worn set of Avons,the 90/90 x 19 f.and 100/90 x 18 rear,I thought they were great,in all weathers,but,

changed them for 3.25 x 19 f,and 4.00 x 18 r,Dunlop arrowmax,both sets running 29psi F,and 36 psi R ,

so far after about 200 mls these seem even better !!

I also modded the forks to fit second disc,used ATF ,and still the original springs,nice soft and progressive,

Ian DB:
I've been having a think about changing the tyres on mine recently, they both look ok and have decent tread depth but I'm unsure as to how good they are, only having had the bike for a month or so.
The front is a Kenda Challenger 100/90-19 and the rear is a Cheng Shin C289 MN90-18 (4.00-18) The rear looks in proportion but to be honest the front does look a bit wide for the rim

The workshop manual states the original spec to be Front 3.15-19 or 3.25-19 and Rear 3.50-18
 
I'm getting a bit of vibration through the handle bars even though I've rebuilt the forks and stripped down the stearing head and cleaned up the bearings etc. As the ball race bearings looked in good condition i have retained them for the time being, perhaps changing to taper would have been a better option. But will see how we go. Perhaps the tyres could be the cause?

The Avon and Dunlop options look and sound great but does the modern style not detract from the classic lines on the bike?

Ian
