So I got it to run today, basically the fuel tank was dirty and was not sending fuel into the bike. Once it was running, it was crazy, I loved riding every minute of it, it'll come tomorrow here to Gainesville via my dad's truck and I'll pictures. The weird thing is that I read a lot about tire sizes on the forum when I read through all of it yesterday and today I noticed on the back that they are 180/55 on the rear. No rubbing, I'm going to buy new tires because they both are super bald but my question is should I stick with the 180 since it's on there already and it fits perfectly. I read that it's dangerous to have it on there so I don't know if I'm going to stick with that tire size.

 

^^^^up to you on the 180...160 is the factory recommended though.

I like the look of 180, it's a good look but most importantly what performance issues may arise? Also, will a 160 fit on the same rim. Thanks for the help.

 

btw the way here is a picture of the bike up on the truck before it gets moved up to gainesville (sorry for the crappy cell phone pic), it's completely nakid but I have all the fairings and tank. The previous owner just took them off to paint them but never did.

 

Are you sure its a 180? From the looks of the pic, it leaves alot of space from the tire hugger. I run a160 Pilot and there's not much space...Hmmm.

Yeah, I'm positive it's an 180. I checked on the side of the tire again, Dunlap 180/55/R17, that's what's so wierd, there is a lot of space between the hugger.

 

I bought my f2 and the same thing. It is almost def the carbs. Drain the bowls on all carbs, empty gas tank. If it still don't start tear em apart and soak em, if you can't do it yourself it'll cost 2-3 hundred at the shop( and that includes sincin 'em in).

 

I've already got it to start but I'm still going to clean the carbs soon.

 

look some people say yes a 180 will fit but think try putting 9 inch wide tire on a 3.5 rim, mushrooms not safe i have a 91 f2 i'm working on i put "93 900 rr rim which holds 180/55/17 and fit bike had to use different spacer but had to loose rear hugger due to rubbing rim has same spoke pattern

 

See that's the weird thing, I read that 180 causes a lot of rubbing but there is plenty space for it, I think the previous owner has already modified it to be able to support a 180 size tire.
