Are you running stock ratio Jimmy was going to do a 41/17 but damn it is hard to find that 41 it is out there just no one carrys it except JT and the only place I found that was the dist !!!!

This last time I went to the 16/42 to help offset the effect of the oversized rear Metz (1780/80). Why would you do a 17 and a 41? That would be kind of working against each other. A 17 and a 41 basically would not change from stock since a larger front sprocket lowers rpm's while a larger rear raises rpm's.

Well as you know we divide the 2 numbers and get the ratio like stock is 16/40 which is 2.50 the lower the number the better the gas mileage but what a dog off the line.. Now 42/16 is 2.62 so that means your bike is reving around 5500 or so around 75 and you are quick off the line. I was going for something close to stock but wanted the mileage being that I put 120 miles aday on my baby 60 miles one way. So I figured 17/41 is 2.41 which is close whith out giving to much off the line!!!!!

Hmmm. What rear tire are you running?

I'm probably wrong but I still think what you will end up with is the same as stock gearing. I always thought 16/40 was great with the stock size rear.

I tend to agree with Jimmy, I was running the higher ratio (17 front sprocket) when I first got my 97. I thought the Magna ran great except for the sluggish take offs, all the higher revs and clutching slipping on starts pretty much off set any mileage increase I might have got out on the highway. After I changed it back to a 16 it made all the difference in the world in take offs and I can't tell any difference in mileage. As I said before there is no way I would go back to a higher ratio..Gas milage increases are usually so small that they rarely offset the cost to achieve it..Just my uneducated observation,

Well right now the 170/80/15 but I am going to have to go smaller when I put a new tire on so trying to figure that out too Was thinking about the stock size Metz on the rear should give me great turn in. I am also going to get rid of my forward controls and put the stock pegs back on.... The forward controls I have on now do NOT MOVE as in if I am not careful I will find myself with the bike sliding out from under me not a good thing and I enjoy leaning so they got to go !!!! Would love to figure out how to mount them back like sportbike style. I will save that for another post LOL....

I don't know bro. If you are wanting a stock rear tire then I don't understand the 17/41 gearing. Maybe 16/41 if you want more take off without losing too much mileage but then if you're liek me the quicker take offs just make you twist the throttle more...lol. Best way to help gas mileage is just do the hardest thing, stay out of the throttle. Honda pretty much nailed the stock gearing with the stock size tire IMHO.

SO you have the older stype Mapam's with the non folding pegs? Yikes!!! I can imagine how those would lever a bike up at angle. Not a good thing!!! I have actually thought several times about going back to stock pegs but just never do. I mean, after all I have put my forwards through it kind of seems mean to take them off

roboto65 · November 27, 2007, 06:16:46 PM

Well my back does not like them either hunched over with your legs out not a good combo !!!!

Len, I have the tool to use when removing/replacing the chain, if you want to come by some evening or weekend it is doable in about an hour. Just make sure you have the right size chain. I bought one from Honda once after giving them the bike numbers and they gave me one too short. (is this what you meant by making a chain?)
Bob

Yep thats what I meant. Sounds like a good Idea. I just need to by the chain.

Curtis_Valk · November 30, 2007, 03:51:21 PM

Len, let me know when you plan on going by Bob's to do the chain. If my schedule allows I'll drop by and visit while ya'll work.

silveradocowboy · November 30, 2007, 08:41:40 PM

Let me know also...

I just got new Sunstar sprockets (16/40) from Dennis Kirk $86.93 wiht shipping (front 25.99, rear 53.99, both steel) for front and back and a RK-530XSO chain from Cyclegear $75+tax and a chain breaking riveting tool from Pit Posse (through ebay) for $52.

I'm fairly pleased with prices...although we'll see how long the RK chain lasts. Do you guys know what chain comes Stock? When I got my bike it had less than 4K on it, but it had a D.I.D. chain on it.

roboto65 · December 01, 2007, 04:17:31 PM

I just did the same thing from Dennis Kirk LOL went with stock also got front wheelbearing and seal kit !!!!!!!!!!!!

Manual shows two chains:

DID 50V4/118
RK 50 MF0Z1/118

Herman · December 02, 2007, 09:26:43 PM

DID 50V4 would be the one. Got just about 24K out of it. I wish I could get that out of a rear tire!

Len, congrats on the chain stuff. Hope you got what you needed with the chain break tool, I know when I was shopping around there were a lot of variations and prices for what they were offering and it was hard to tell what was in the kit, some kits had this and some had that. The $100 kit was the one I knew had all I needed to do the job.
If you need any advice or run into issues while doing the job give me a call, any time... My cell is 9723587079. I have done about 5 chain jobs on my Magna and others.
Bob
