12/42 does work - I run that combo on one bike, and it gives basically the same ratio as the 13/45 combo. But, you can keep your stock chain, leave the chain guard on, and it puts the axle in the stock position. The 12 might result in a little more chain wear... but if the chain wears out too fast for your liking, you can go 13/45 (one link longer chain) or even 14/48 (two links longer) at that point.

13/45 with a longer chain is what I'll do on mine when the chain wears out. I can easily swap it to a 14t front for more all-around use, or 45/15 to get back the ability to cruise 75mph+ on the freeway.
45/15=3, is really close to 40/13=3.07. I like the idea of swapping the front, since it takes so little time, even figuring in chain adjustment. Wondering if with a 45 rear, you could use the same length chain with all those 13, 14, and 15 fronts, and still be able to have the correct slack.

Any help on this matter would be appreciated, thanks.

On all three of our bikes, there's enough room to run two extra teeth. 15/45 with a +1 chain is the same as 13/43 with a stock chain, which seems to work well for lots of people. So, in a word, yes, it'll work.

Will a 15T front fit with the standard rear and chain?

Would help when there is a lot of tarmac to cover,
Thanks
Lloyd.

The storm picked up some speed, I guess, 'cause even with me doing my planned 55 and 65 mph I had my first opportunity of riding in the rain the last 10 miles... a rather driving rain... a good soaking.

But, it was worth it. I had a good laugh at myself... the cold and wet made my hot shower feel SO much better... it seemed like some kind of motorcycle-rider-initiation... and, it was kinda fun... just like the other 5,500 miles I've ridden since purchasing my CRF250L on March 29.

Thanks to the various commentaries of this forum I've gotten to know much more about this whole motorcycle thing (I'm trying to NOT learn everything through experience.) Last week I even purchased the stuff needed for another new adventure still to come my way when I decide to replace my OEM rear tire (still a few mm on the center blocks that I might as well make use of.) I also ordered some oil filters today... knowing that changing my own oil soon will be yet another new adventure for me. I'm good with the typical changing of oil at 5,000 miles with my car (at a dealership service department, however) but I'll try taking task this on myself with my motorcycle. The apparently typical tire replacement rate with motorcycles caught me a bit since I'm used to thinking of tire wear in terms of my car... 70K to 100K between changes. Ah, well... I've enjoyed all of the various adjustments and adventures that have come along with my recent purchase.

(This is also my first adventure of "posting" on this forum.... whoo hoo!)
with the point of trying NOT to learn everything through experience , waterproof-ness of some sort is excellent for commuting: One-piece suit from Aerostich or Olympia (or other vendors), or jacket/pants that are a pain for commuting (YMMV) but are easier for non-commute rides.

enjoy your cool bike!

I think so, but I haven't tried yet. See here:

http://advrider.com/forums/showpost....postcount=4691

Also, 15/40 won't boost top speed at all. In fact, you'll end up being faster in 5th gear. I think 15/40 might make 6th kinda useless unless you're going downhill, or just want to cruise at 65mph at lower revs. Now, with a bunch of power mods... you might be on to something. But without a 305 jug, cam, programmer, and exhaust, you won't see me gearing a LRP over 14/40.

Ramz' site

Just checked on Ramz site, haven't been there in a while. Info on seal doctor, might be something for the tool kit, even preventative maintenance, before you get a leak. Knowing about the old 35mm negative fix, but like Ramz, I've gone digital also. http://www.rickramsey.net/CRF250Lmods.htm#sealdoctor

Welcome to the world of dual sport! I'm 70 miles South of you "Where the North Begins" in Portage. I ride a WR250r though... Doing the tire change yourself? The first several are a pain. Get an extra tube and irons, watch youtube videos several times before attempting, and be ready to swear like a long shore man.

Thanks! I saw this before, either on this thread, of some other, bookmarked it, then my laptop got toasted. Much good info here.

I just removed the spark arrestor from my FMF PC4 (out of curiosity) after a fair bit of fiddling about as it was properly lodged in there. Once out I noticed that there was a fair bit of steel wool built up on the inside. I know the purpose of this part is for this exact reason, but for 2400kms this seems excessive?

I am assuming the muffler is designed as a perforated tube down the middle with lotsa holes in it, with the "can" around the outside packed with a sound absorbing material (steel wool in this case). Steel wool is generally considered the lowest temperature, lowest cost "packing" material. Also, it rusts....and exhaust gas contains lotsa water. Other choices are glass wool, which is next in temperature resistance, and "rock" wool or mineral wool the highest temperature resistance. How tightly packed the "wool" is affects how quiet it will be....loosely packed generally more sound absorbing, but lest durable. I further assume FMF sells materials to repack the muffler. Such designs require occasional rebuilding (re-stuffing). So much for how these mufflers are designed....the bit of steel wool looks like a wad of steel wool that was left loose in the muffler during a sloppy packing job, rather than dislodged during usage. I'd email FMF and see what they think. Again...all my opinion.
