What year of a Z? Does it matter?

Thanks for the advice wht180.. my Yosh full exhaust is on its way.. what if I'm a bit bigger than usual?? like 6'-2" and 225 on a good day :D and another thing.. with the lid off and the cherry bomb and the full rs-5 yoshi exhaust I still don't think youd be getting close to the 50 HP mark... I'm thinking more around 42-45???? my neighbor owns K&T Performance and has a dyno.. he already said we should do a before and after.. if he is not too busy and has a few extra hours I'd love to take him up on that.. and if I do I will make sure to post the results.. just not under this topic! I have already blended about 5 other topics together just with this post...

13/38 is what I plan on running just like the ole 250R.. I hope this will work out for my 20x10x10 sand snakes and 21x7x10 diamond traks.. I have the front 13.. but I know of no-one that has a 38t rear out yet.. I am also waiting for my dynatek F.I. programmer.. with the full Yosh RS5 I have and the sparky removed I'm almost certain that the cherry bomb isn't enough.. so there my LTR sits in the garage waiting for a few things..

Does the chain need to be shortened with the 13 tooth sprocket? Does it need to be removed to get it on? I have not checked mine yet to see if there is a master link on the chain. ANy comments would be helpful as I need to order my 13 tooth sprocket for my new paddles.
Best regards,
Scott

I was just looking on the Suzuki website, the z400 uses the #520 chain and the r450 uses the #525 chain.

Here is the difference? I found this info at http://www.everything2.com/index.pl?node_id=1342594


A motorcycle chain is the most common method used to connect and drive the rear wheel in a motorcycle. The others are belt drive and shaft drive.
Chain size is in inches, the three digit number used to discribe the chain size is based on the "rule of eights". The first digit is for chain pitch. This is the distance between the pins. The second and third digits combine for roller width, with a decimal point inserted between the second and third digits.

For example, a 420 chain has a pitch of 4/8" = 1/2" (12.70mm) and a roller width of 2.0/8" = 1/4" (6.35mm).

A 525 chain (the size my bike uses) has a pitch of 5/8" (15.88mm) and a roller width of 2.5/8" (7.94mm).

A 530 chain has a pitch of 5/8" (15.88mm) and a roller width of 3.0/8" (9.52mm).

There are a number of chain sizes in use, and chain manufacturers may have slightly different specs for roller diameter, sprocket width, etc. But a 525 chain from one manufacturer will have the same pitch as a 520, 525, 530, or 532 chain from another and run smoothly on any 525 sprocket from any manufacturer.

So if I'm interpreting this correctly then the r450 with a 525 chain just has a wider roller width and 520 sproket shouldn't effect the chain at all...except maybe grabbing a little less roller as it goes around? Help me out with this boys :oops:

well if thats the case, then a set of calipers tonight will tell all.

edit:
side thought, aren't 525 chains more used on street bikes? if so, then maybe we need to look at one of them for a front and rear sprocket....

edit again:
Both the Z400 and the LTR450 use 520 sprockets and chains. We own one of each so this is pretty easy. Also notice the bolt circles:



LTR rear sprocket 36-520



LTZ reat sprocket 40-520

From the dead. I'm getting tires [attachment=7640:blah.gif]...

Maybe I can't find the thread where this get explained or whatever.

but... I need a 520x?? chain for a 13 tooth sprocket. I personally don't have a chain breaker so correct size would be cool, but if not my friends should have one.

Since I'm a first time chain buyer, is an X or O better for a woods rider. Mud, water, dirt the works. Any prefered brands for chain and sprocket. I don't want to drop 150 in a chain and sprocket but I'm not going to low ball and have it last like the stocker did so its not a huge deal. Master link, Does it come with a chain purchase or do I need to order it also?

Sorry I'm a turd. :lol:
