1000 FJ Tyres + Suspension...confused!!
Hi guys,
as some of you know there were some bits and bobs I wanted to get done on the CBR 1000FJ I recently purchased. With a tyre upgrade being one of them.
As I wanted to get back into doing bits on my bike myself, this weekend gone, I took all the farings off to get on with an oli +oil filter change and a coolant flush.....apart from the fact that I found numerous 'DIY' repairs on the farings ( which as Im particular about things makes me want to replace them all! ) I also checked the tyres.......this is where Im confused.
I've looked at other threads about tyre sizes on these FJ's and gather that you can get a max of a 120 on the front ( tho apparently 110 is recommended ) and a max of a 150 would fit on the rear...I found that mine had 120 on front and a 160 on the rear!!!
Is this unsafe??? And does it impact negativly on the handling or conering of the bike???? I cant tell myself...its been 4 years since I rode my last CBR and I have to say its seems ok when I ride it, conering is fine ( apart from when my Mrs is on the back and chits herself going around roundabouts )
On another note to I was thinking of playing with the suspension setting to see the difference........what is the difference between hard/soft suspension and what would you more experieneced guys recommended with the FJ???

Yep, you'll have no problem running 150/120. People run bigger than that, but at +1 like you are now, you're fine.
As far as removing the fairings, I think the manual says you have to remove plastic to do the oil changes, but you don't. Just FYI in case you didn't know. If you don't have an oil filter socket, you should get one. You can access the filter through the front wheel well with the socket and an extension, and just drop it out.

I'll know for future oil changes I didnt have an oil filter socket so had to ram a screwdriver in it to get it off....luckily the new K+N oil filter I put on has a wrench nut on it so I could just screw it on with a normal socket
As for the suspension..anyone got any advice???

Haha... I did the same thing to my oil filter on my jeep when I couldn't find my filter wrench. I used a screwdriver...
As far as suspension, it has been covered here several times. You can do a search on "suspension" in this section and you'll have plenty of reading. Also, download a factory service manual in the "how to" section if you don't have one.
Here is a pretty useful thread.... Rear Preload Adjustment

Thanks, I'll read up on it Just so many things to read up and learn about now Im back on a bike
Ive also booked the bike in for a K+N air filter, re-jetting and re-synching of the carbs....once this is done, I better research some recommended tyres to put on the bike.....then maybe a respray lol

It seems the OP is saying he has a 120 on the front (no problem, it's one size up) but he has a 160 on the rear (which is two sizes up).
I'm interested in an informed opinion about this as well as I have a 110 on the front and a 150 on the back. I'm planning on going to 120 front and 150 rear but it can be hard to find rubber for the rear at sizes less than 160. If 160 is okay on the rim, I would consider running it, which I think is the jist of the OP's question.

Grif, good catch. I don't know why I thought he said he was running 150s.
I know most recommend no bigger than 150 on the rear on the early ones.
You have a 3.5" rear wheel, right??
People do run 160's on the older ones on 3.5" rims, I do know that.... BUT I don't know if I'd do it. Your best bet is probably just to buy a later model 90+ rear rim and fit what's easy to get (180 if you like).
