maxim and seca fork spring compatibility

I have a 82 xj 550 maxim and I am looking at purchasing some progressive replacement fork springs.

In my search I found that the seca takes part number 111114 and the maxim 111111. Are they just different spring rates? Can I put the seca springs in my fork to get better performance?

Can or should I run different weight shock oil from stock with the progressive springs?

Finally, Fork seals, cheap ones ok?

thanks

 

Springs. Not my bag, sorry but I'm going to say that you shouldn't get the Secas springs for your Maxim given the difference in weight and the different types of forks. You're liable to introduce some problems even if you can still get the fork caps back on.
On the seals, I can offer an experienced opinion. Buy the Yamaha units. They just flat out last longer and are of better quality. Few bucks more but worth the extra years you don't have to go back and replace them!

 

Hey Main, I just did the fork seals on my 550 Maxim. I had very heavy brake dive and the bike didn't feel balanced with the stock 10w oil. When I reassembled I used a 3/8 spacer on top of the spring and went to 15w oil and it made a huge difference. It cut the brake dive in half and the bike feels a lot more stable and balanced.

 

thanks for the replies.

I was just looking at a parts diagram, am I replacing the dust seal and or oil seal on these forks?

 

You are primarily concerned with the oil seal, however, the dust seal is the first line of defence for your oil seals. Depending upon what shape the dust seal is in, replace it also. Just a little more insurance at about $13 a pop.
